Manufacturing of Q295GNH Weathering Steel Plates

　　Q295GNH Weathering steel manufacturing process

　　Q295GNH weathering steel plate is generally used in the furnace-smelting (converter, electric furnace-microalloying treatment-argon-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. 153 is smelted 812 according to the normal 78 gauge process 738. After the tapping, the deoxidizer and the alloy are added. After the molten steel is subjected to argon blowing treatment, the molten steel is immediately cast, and the molten steel after the argon temperature adjustment is cast by the continuous casting machine. As a slab, due to the addition of rare earth elements in the steel, the Q295GNH steel plate is purified and the inclusion content is greatly reduced.
