Three advantages of semi-endless rolling technology: 1. The limit specification of Q345B steel is expanded from 1.5 mm × 1300 mm to 1.5 mm × 1600 mm. 2. the semi-endless rolling technology can effectively reduce the fluctuations in the temperature, size, and shape control accuracy of the strip head and tail. 3. The different parts of the strip steel KA36 ship structural steel plate produced by semi-endless rolling have uniform structure and mechanical properties, the yield strength fluctuation is less than 40 MPa, and the tensile strength fluctuation is less than 20 MPa.
Composition characteristics of low alloy structural steel, KA36 ship structural steel plate: (1) Low carbon: the carbon content of low alloy structural steel is less than 0.20% due to the high requirements of toughness, weldability and cold formability. (2) The alloy elements such as manganese are added. (3) The addition of Nb, Ti or V and other auxiliary elements: a small amount of Nb, Ti or V forms fine carbides or carbonitrides in the steel, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of low alloy structural steel. In addition, adding a small amount of copper (≤ 0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. The addition of a small amount of rare earth elements can remove sulfur and gas, purify the steel, and improve the toughness and process performance of low alloy structural steel.
The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the KA36 ship structural steel plate principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
