The problems found in the after-sales service shall be summarized in a timely manner, discussed with the technical department, the quality inspection department and the production department, and a proper solution shall be proposed for the technical department to improve in a timely manner;Converter steelmaking: The furnace body of the converter can be rotated, and the steel plate is used as the outer shell, and the refractory is used as the inner lining. Converter A387 grade 11 class 2 pressure vessel steel sheet steelmaking does not require additional heating, because the molten iron is inherently high temperature, and it still continues to generate thermal oxidation reactions (from silicon, carbon and oxygen in molten iron).Because no more fuel is needed for heating, energy consumption is reduced."BBN STEEL A387 grade 11 class 2 pressure vessel steel sheet 2020 newly inventory in Shanghai(500tons)16*1524*5900, 5*2800*12000, 15*2000*12000, 6*2500*12000, 10*2120*926012.5*1820*6096, 10*2900*7350, 24*2650*11100, 5*2800*12000, 8*2600*1000016*1524*5900, 8*2800*11230, 19*2910*11025, 32*2700*11025, 10*2270*711010*2120*9260, 65*2100*6000, 22.5*2910*11025, 12*2050*7780, 14*2050*90008*2600*10000, 10*2270*7110, 36*2140*9150, 40*2910*11000, 57*1600*6000Product concept: take the technology leading as the pillar of the enterprise, achieve the development goal of the enterprise with the reliable products, the reliable technology and the trustworthy services, and devote to the creative reform activities leading in the technical development and career of the industry to create new value through continuous change.
