Furnace charging into the furnace and power transmission

First, the charge into the furnace:
Charge into the blast furnace, electric furnace steelmaking operations plan should be based on the ingredients in a single audit charge weight and alloy elements and ingredients and feed weight pad in the bottom 1 to 2% of lime.
Top loading baskets have someone directing, opened the lid, it should promptly baskets hanging into the center of the furnace may not be too high, too biased and too low. In baskets of chain plate is not bad as far as sticky lower. For the second feeding, not other primary materials entirely of clear before feeding, to avoid spraying and splashing of molten steel, but also to prevent the explosion, humid charge non-loading of the material into several baskets.
After charging into the furnace, for excessive burden should flatten or hanging out, so as not to affect the fastening lid while preventing the lid was arcing and leakage.
Second, the power transmission:
Charge into the furnace after the power transmission before the deal lid, electrodes, cooling system, mechanical transmission, electrical equipment, etc. for inspection, if found to be timely treatment failure, resulting in the smelting process in order to avoid downtime; also check the charge with the door or cooling system is touching, if exposed to immediately exclude, in order to avoid transmission after breakdown.
If the electrode is not long enough, it is best replaced before the transmission, such as loose fitting location, should be tightened in order to facilitate a Chuanjing success, reducing downtime caused by the phenomenon of the smelting process.
