What is steelmaking process of 15CrMo steel plate

15CrMo steel plate is a heat-resistant steel with pearlite structure, which has high thermal strength (δb≥440MPa) and oxidation resistance at high temperatures, and has a certain resistance to hydrogen corrosion. Due to the high content of Cr, C and other alloying elements in the steel, the hardening tendency of the 15CrMo steel is obvious and the weldability is poor.

Steelmaking process of 15CrMo steel plate:
1. Raw materials (scrap steel, pig iron and molten iron)
2. Electric furnace (100-ton electric arc furnace smelting), converter
3. LF furnace molten steel refining treatment
4. Vacuum treatment of molten steel in VD or VOD furnace
5. Die casting (a variety of key die casting lines) or continuous casting (large slab continuous casting machine); (a steel ingot remelting treatment 50 tons slab electroslag furnace)
6. Heating (continuous furnace and soaking furnace)
7. Steel plate rolling (4100 and 4200mm rolling mills)
8. Heat treatment of 15CrMo steel plate (normalizing, tempering, quenching and tempering)
9. 15CrMo steel plate cutting inspection
10. Storage
