If steel plate unti-dumping in Europe?

  By

Yes, there are anti-dumping measures in place for certain types of steel plate imported into the European Union (EU).

Anti-dumping duties are imposed on steel products when they are sold at a price lower than their normal value in the exporting country, and when this causes material injury or threatens to cause material injury to the domestic industry of the importing country. The EU has initiated several investigations into alleged dumping of steel products, including steel plate, in recent years.

For example, in 2018, the EU imposed anti-dumping duties on certain types of steel products, including hot-rolled flat steel products, originating from Brazil, Iran, Russia, Serbia, and Ukraine. The duties ranged from 17.2% to 37.9% depending on the country of origin and the specific product.

It is important to note that anti-dumping measures are not applied to all steel products or all exporting countries, and they can change over time depending on the specific circumstances.

How to produce high thickness steel plate?

  By

Producing high thickness steel plates involves a number of processes and considerations. Here are some general steps that are typically followed:

  1. Selection of raw materials: The first step is to select high-quality raw materials, which typically include high-grade steel alloys. These alloys have properties such as high strength, toughness, and resistance to corrosion and wear, which make them suitable for use in high thickness steel plates.
  2. Melting: Once the raw materials have been selected, they are melted in a furnace. The furnace must be able to reach high temperatures in order to melt the steel alloys. The molten steel is then poured into a mold.
  3. Rolling: The molten steel is then rolled into a plate using a rolling mill. This process involves passing the steel through a series of rollers, which gradually reduce the thickness of the plate.
  4. Heat treatment: Once the plate has been rolled to the desired thickness, it may undergo a heat treatment process to improve its mechanical properties. This involves heating the plate to a high temperature and then cooling it down rapidly.
  5. Finishing: The final step is to finish the plate by cutting it to the required size and shape, and then applying any necessary surface treatments such as painting or galvanizing.

It’s important to note that the exact process for producing high thickness steel plates may vary depending on the specific requirements of the application, as well as the type of steel alloy being used. Additionally, producing high thickness steel plates requires specialized equipment and expertise, so it’s typically done by specialized manufacturers who have experience in this area.

Pressure vessel steel plate from Hanyesteel made a major breakthrough in the high-pressure steam drum industry

  By

On August 19, 2020, Dongfang Boiler Co., Ltd. of Dongfang Electric Group in Zigong City, Sichuan Province received good news. hanyesteel’s 150mm thick high-pressure steam drum plate 13MnNiMoR passed the company’s boiler vessel steel certification. The steel plate is being tested. The performance indicators in the medium are qualified and the simulated use performance is good. It can be used in the high-pressure container steam drum manufacturing industry. This marks another big step forward for the special container steel plate produced by Nanyang Hanye Special Steel Co., Ltd. in the steam drum industry.
In response to the group company’s slogan of enhancing competitiveness with “richness, improvement, reduction, and excellence” as the core, Nanyang Hanye Special Steel blew the Charge for the 150mm 13MnNiMoR certification campaign. In September 2018, Hanye Special Steel Research Institute and sales personnel went to Dongfang Boiler for the certification and exchange of boiler drum plates. In December of the same year, the product development was carried out. In May 2019, the national standard limit thickness for special container drums was completed. The 150mm 13MnNiMoR steel plate was developed, and the 13MnNiMoR evaluation technology agreement was signed with Dongfang Boiler and the evaluation test board was distributed. In August 2020, Dongfang Boiler Company completed the supply state of the test board, simulated thermal cycle state, and welding evaluation. The evaluation result of Dongfang Boiler is: “The 150mm 13MnNiMoR steel plate produced by Nanyang Hanye Special Steel meets the requirements of GB/T 713 for boiler and pressure vessel steel plate and Dongfang Boiler Enterprise Standard DG1806, and can be used for steam drum container manufacturing.”

According to the technical evaluation requirements, the difficulty of technology research and development is: simulating the thermal cycle process, which must be combined with the simplified thermal cycle process procedure of Dongfang Boiler Co., Ltd. for simulation evaluation. First, it needs to combine the pressing capacity of Dongfang Boiler’s equipment, so the high-temperature pressing temperature should not be low; second, Dongfang Boiler proposed that if the normalizing deformation process of the 150mm head plate adopts water cooling, it will increase the calibration cost, so the normalizing air cooling deformation technology should be adopted. ; Third, in order to reduce the cost of the process, the customer actively proposed to use the normalizing suppression process to replace the normalizing suppression + normalizing recovery performance process. In order to meet the various special technical needs of customers, it undoubtedly adds technical difficulties to ensuring good strength and toughness after thermal cycling. According to Dongfang Boiler, the 13MnNiMoR produced by a well-known domestic steel company has unstable impact toughness according to the simplified thermal cycling process. For this reason, Han Metallurgical Steel Research Institute has collected a large number of domestic and foreign technical data, compared with international advanced and mature steel companies, organized more than dozens of heat treatment simulation tests, and carried out comparative technical analysis and summary around the clock to optimize the best thermal cycle process. , Through unremitting efforts, finally meet the various special technical needs of Dongfang Boiler.
It is reported that 145mm is the current limit thickness of the plates used in the domestic pressure vessel steam drum industry, and it is a bright pearl product in the boiler vessel steam drum industry. Out of confidence in our own product technology and capabilities, our company directly assessed the national standard limit thickness and the maximum thickness of 150mm in the steam drum industry. Confidence comes from confidence, and confidence comes from unremitting efforts. In order to ensure that the test process is known and controllable, and the key progress is followed up on site, the Institute of Iron and Steel Research and the sales staff track the evaluation process throughout the whole process, and after unremitting efforts, the victory is finally achieved.
The certification of 13MnNiMoR for steam drum container steel with thickness of 150mm has written another page and new chapter of our company in the field of boiler and pressure vessel products, and can provide technical evaluation support for large domestic boiler plants such as Harbin Boiler and Shangguo. This breakthrough has further established the confidence of all employees in the development of the company. Under the leadership of the group company, the employees will work hard to move forward and create a new era belonging to Hanye Special Steel.

Hanyesteel supplied for China’s first fast reactor nuclear power demonstration project

  By

With the economic development of the world and the deterioration of the global environment, the construction of nuclear power and the use of nuclear energy have become the focus of the next 10-20 years. my country has made significant progress in the development and construction of nuclear power, and the fourth-generation nuclear power technology has reached the international advanced level. Among them, the 600MW demonstration fast reactor project of the fourth generation nuclear power can lead the development of the industry and has extremely important strategic significance.

As a demonstration fast reactor, this project has extremely strict requirements on the safety of equipment. Among them, the refueling system in the key equipment stack mainly uses 20#Z25/Q245RZ25 carbon steel plate. This steel plate is very different from the conventional carbon steel in terms of comprehensive performance and organization, especially in the element composition, grain size and surface quality of the steel. The requirements for the uniformity of the performance of the steel plate and the whole plate are nearly harsh, so that during the material bidding period, the domestic old-age nuclear steel production enterprises are discouraged, thinking that the material design is unreasonable, and propose a large number of technical clarifications. The carbon steel plate used for the cock parts has become the material of the “stuck neck” of nuclear power equipment.

In July 2019, the relevant leading organization of Hanyesteel held a mobilization meeting for the production of carbon steel plates for nuclear islands, and determined the development of carbon steel plates for nuclear islands as a “key project of the group”. Facing the national demand, the Hanyesteel Nuclear Power Steel Project Team fully undertaken the project R&D, production and supply tasks in conjunction with the contract. Under the unfavorable factors such as nuclear island steel plate research and development, less production experience, many product units involved, complicated processes and strict technical indicators, etc., the full advantage of the integration of production, marketing and research was fully utilized, relying on the “three special” advantages, the steel grade was established The production process route successfully realized the steel plate product development of the fourth generation nuclear power 600MW demonstration fast reactor project. The delivery was completed in March 2020, and the first contract supply was completed. The fourth-generation nuclear energy system, sodium-cooled fast reactor, was used for the localization of carbon steel plates in the reactor refueling system, which solved the problem of scratching the product from scratch.

At present, the relevant products have been delivered to China First Heavy Machinery Co., Ltd. for the demonstration of the independent construction of fast reactors. Therefore, Hanyesteel has become the only company in the country to rely solely on its own equipment to produce this product. In the next step, the Hanyesteel nuclear power steel project team will continue to carry out in-depth research and development of the product, further optimize the production process, improve the process route, reduce production costs, shorten the manufacturing cycle, and fully support the construction of my country’s fourth-generation nuclear power 600MW demonstration fast reactor project.
