At the same time of doing well in A572 grade 65 CS steel carbon plate production and operation, Yunnan company focused on completing the four phases of technical transformation construction projects, realizing industrial upgrading, improving equipment level, and laying a good foundation for the future development of the company. In the A572 grade 65 CS steel carbon plate technological transformation project, pollution control facilities have been built synchronously, and a large number of comprehensive utilization projects, such as comprehensive sewage treatment and recycling project, blast furnace gas waste heat and residual pressure power generation, have been invested and constructed.
Our company is located in the Central Plains, Zhengzhou City, convenient transportation. There is the largest Xinzheng airport, welcome customers from all over the world to visit our company. Our factories are all located near the port. The logistics is very convenient, which can save the delivery time.
The hot rolling method is to heat the A572 grade 65 CS steel carbon plate steel material to about 1000 ℃ ~ 1250 ℃ and use the rolling mill to roll it. The traditional hot rolling process is generally divided into the following two steps: the first step is to use the primary rolling mill or billet rolling mill to roll the ingot, billet or continuous casting billet into a certain shape and size of billet. This kind of A572 grade 65 CS steel carbon plate rolling process is usually called semi-finished product production, also called blank production.
In 2014, we offered 175 ton Cold rolled stainless steel plate to Thailand. The A572 grade 65 CS steel carbon plate products are from TISCO. Here is the MTC that we offered to customer. We have our own quality team. Our quality team will inspect every order before shipment for customer. Normally, we will test the chemical composition, thickness, width, and length. Here are some pictures for last inspection.
Chemical composition differences between the A572 grade 65 CS steel carbon plate, Q345 steel grades (Q345A / Q345B / Q345C / Q345D / Q345E):Q345A steel:C≤0.20,Mn ≤1.70,Si≤0.50,P≤0.035,S≤0.035; Q345B steel:C≤0.20,Mn ≤1.70,Si≤0.50,P≤0.035,S≤0.035; Q345C steel:C≤0.20,Mn ≤1.70,Si≤0.50,P≤0.030,S≤0.030,Al≥0.015; Q345D steel:C≤0.18,Mn ≤1.70,Si≤0.50,P≤0.030,S≤0.025,Al≥0.015; Q345E steel:C≤0.18,Mn ≤1.70,Si≤0.50,P≤0.025,S≤0.020,Al≥0.015; All the Q345 steel grades contain Nb≤0.07,V≤0.15,Ti≤0.20,Cr≤0.30,Ni≤0.012,Mo≤0.10。
The company uses online training system to let all employees use fragmented time to carry out targeted training anytime, anywhere, regardless of time and geographical restrictions. Through training to improve A572 grade 65 CS steel carbon plate work skills, at the same time, through training, let all improve their own quality education level, let employees work around a goal, create a career and achieve results.
