Wear resistant steel plate is often used for construction machinery and equipment manufacture, such as excavators, scrapers, sand making machines, etc., which operate repeatedly in the sediment for a long time. That requires the wear resistant steel plate have good wear resistance. Otherwise, once the mechanical equipment is damaged, the progress of the whole project will be greatly affected. GL-DH 32 coal carrier steel plate, Wear resistant steel plate can also be used for building equipment, such as excavation machinery, shovel transport machinery, compaction machinery, engineering lifting machinery, piling machinery, etc.. They need long-term contact with all kinds of sediment, and need the support of wear resistant steel plates.
The surface quality of pickling coil is very good. Compared with ordinary hot-rolled plate, GL-DH 32 coal carrier steel plate, the surface quality of hot-rolled pickling coil is improved in addition to the oxide scale on the surface, which is convenient for welding, oiling and painting. The accuracy of pickling coil specification is high. After leveling, the shape of the plate changes to a certain extent, thus reducing the deviation of unevenness, improving the surface finish and enhancing the appearance effect of pickling coil.
Weathering steel generally adopts the process route of fine material into the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire)-controlled rolling and cooling. The scrap steel is added into the furnace together with the charge, and smelted according to the conventional process. After the GL-DH 32 coal carrier steel plate steel is tapped, deoxidizers and alloys are added. After the molten steel is treated with argon blowing, the molten steel is cast. By adding rare earth elements to the steel, the GL-DH 32 coal carrier steel plate weathering steel is purified and the content of inclusions is greatly reduced.
For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate GL-DH 32 coal carrier steel plate EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.
Respect customers and treat each other sincerely. Customers are always right. Always remember that the user is the God of the enterprise, respect the customer, and accept the customer's opinion modestly is the guarantee of the long-term development of the enterprise.
