SPA-H section steel maximum CEV based on the ladle analysis

BBN company team and culture: tt the end of 2019, in order to thank employees for their hard work and enrich their sparetime lives, the company organized a pleasant trip to Phuket Island, Thailand. This tour lasted 6 days and 5 nights, and returned by plane on the evening of December 27. We took off in Zhengzhou at about 5o'clock in the afternoon on the 22th December. Let's seize the day and live it to the full, and greet the arrival of the year 2020 together.

"As Covid 19 spreads around the world, all unnecessary businesses and factories have been closed in Italy this week. South Korea's POSCO, the world's fifth-largest steelmaker, announced on March 24th that it would close its SPA-H section steel wire-processing centre near the northern Italian city of Verona from Thursday March 26th until April 3rd. POSCO has already closed two wire-processing centres in Delhi and Pune. Two wire processing centers in Malaysia and Thailand also announced last week that they will be closed until March 31."

40B steel plate is alloy structural steel plate formed by adding boron to the carbon structural steel with a carbon content of 0.40%. SPA-H section steel, 40B steel plate has high hardness, toughness and hardenability, and has good comprehensive mechanical properties after quenching and tempering, which can be used instead of 40Cr steel. 40B steel plate chemical elements: C: 0.37-0.44, Si: 0.17-0.37, Mn: 0.60-0.90, B: 0.0005-0.0035. 40B steel plate is used to manufacture parts with larger section and higher performance requirements.

The company's logistics uses third-party logistics. This logistics model plays an important role in improving the efficiency of our business operations. Third-party logistics is an important form of logistics specialization. As a company specializing in logistics, third-party logistics companies have a wealth of experts who specialize in logistics operations, which is conducive to ensuring the professional production of the company, reducing costs, and improving logistics level of the company. Both the customers and the company benefit from the logystics mode.

S355J2 steel plate SPA-H section steel rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the rolling speed is 1.6-2.0m/s, the SPA-H section steel single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.

If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.
