Accident handling and prevention of ladle leakage

图片
1. Causes of Leakage (1) Molten steel temperature is too high, and with strong oxidation; (2) The quality of refractory materials or ladle masonry is not good; (3) The quality of purging-plug at the bottom of ladle is poor; (4) Ladle slide gate plate or nozzle is not properly installed. 2. Accident Handling (1) When leakage occurs, the BOF must be lifted immediately to stop tapping; (2) At the same time, the steel ladle transfer car shall be driven away to avoid damage. (3) Lift ladle to the accident treatment area; (4) Inform the relevant personnel around the operation area to pay attention to the leaked ladle, and avoid it in time. 3. Prevention of ladle leakage (1) Check the ladle carefully; (2) Quality acceptance of refractory materials ; (3) Check the masonry quality of ladle working layer; (4) Used ladle before re-use, the residual steel slag must be removed under red hot conditions, and the erosion must be checked in detail; (5) When the ladle

The application of magnesia carbon brick

Magnesia carbon brick is made from high melting point alkaline oxide and high melting point carbon material that is difficult to be infiltrated by slag and various non-oxide additives are added. Magnesia carbon bricks is mainly used for converter, ac arc furnace, dc arc furnace lining, ladle slag line and so on. As a composite refractory , magnesia carbon brick has been used to effectively utilize the slag resistance of magnesia and high thermal conductivity and low expansibility of carbon. Wanhao is a manufacturer who is specialized in designing various kinds of furnace and making refractory products for electric furnace, ladle, tundish, blast furnace, AOD furnace, IF furnace, etc.
