In recent years, in line with the development trend of iron and RB hull structural rolled steel steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which RB hull structural rolled steel are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.
Smelting process of RB hull structural rolled steel, container plate SPA-H weather-resistant steel: The molten iron for smelting SPA-H steel must be pretreated by molten iron desulfurization. Before entering the converter, the sulfur content of the molten iron is ≤0.010%, and the slag on the surface of the molten iron is cleaned. Nickel plates, copper particles or nickel-copper alloys are added to the converter with scrap steel. The carbon content of the converter smelting end is required to be less than 0.06% to prevent the molten steel from being oxidized.
Q345B material is a low carbon alloy steel grade with good overall performance, low temperature performance, cold stamping performance, welding performance and machinability. Q345 serues steel is widely used in bridges, vehicles, ships, buildings, pressure vessels. Q represents the yield of this material, and the number 345 refers to the yield value of this material, which is around 345MPa. As the thickness of the material increases, its yield value decreases.
The RB hull structural rolled steel, wear resistant steel plate is composed of low carbon steel plate and alloy wear-resistant layer, and the alloy wear-resistant layer is 1/3 ~ 1/2 of the total thickness. The alloy wear-resistant layer and the base plate are metallurgically bonded. When working, the base plate provides comprehensive properties such as strength, toughness and plasticity to resist external forces, and the alloy wear-resistant layer provides wear-resistant properties to meet the requirements of specified working conditions.
