SB480M steel plate process

(1) Raw materials (scrap steel, pig iron and molten iron)

(2) Electric furnace (100 tons of electric arc furnace training), converter

(3) LF furnace molten steel essence treatment

(4) VD or VOD furnace molten

(5) Die casting (a variety of key type die casting lines) or continuous casting (large slab continuous casting machine); (1. Steel ingot remelting treatment 50 tons slab electroslag furnace)

SB480M steel plate is commonly used in petrochemical industry, boilers, spherical tanks, petrochemical equipment and so on.
