Problems solved by technology

[0004] Ingot pumping electroslag is an important electroslag method. Ingot pumping electroslag was invented to solve the problem that the length of electroslag ingot is limited by the height of the crystallizer. Using ingot pumping can produce longer electroslag ingots to meet various industrial needs ; However, after the remelting, taking the ingot and cleaning the solid slag in the crystallizer takes a long time in the entire production cycle, about 25%-40%, resulting in low production efficiency; while taking the ingot and cleaning the solid slag in the mold The crux of the long time consumption is that after remelting, it is necessary to wait for the liquid slag on the molten steel to solidify and shrink before pulling out the electroslag ingot. Since the shrinkage rate of the slag is smaller than that of the steel, the solidified slag that solidifies when the electroslag ingot is drawn out often remains in the crystal Therefore, it is necessary to clean the crystallizer separately. For the same reason, when cleaning the crystallizer, it is necessary to wait for the slag to cool and shrink for a long time before cleaning, otherwise cleaning is very difficult, and it is easy to scratch the crystallizer during cleaning.
