Analysis of ball mill liner cast iron process

　　The ball mill liner cast iron process analyzes the production of iron forging, and two of the 0.5T small rinseed flakes. Sabering machine equipment rotation; coke iron ratio 1: 6; 5 water-cooled small iron mold, small bag note, continuous operation, and passengeation production of 300 ~ 400kg. Ingredient ratio (mass fraction): 30%; 20 # pig iron, scrap, 40%. Lying back iron, 30%; two, lining, lining brick production of 2.5T three row of small air mouth hot air flashes, primary focus height 1200 ~ 1400mm, batch 280kg, limestone 20kg, layer 40kg ,. The addition of primary focus and layer has a significant effect on ferrous temperature, carbon and melting rate, and should be severely controlled. Adopt higher scraps to reduce carbon equivalents, which is advantageous to obtain white ports with thick surfaces of castings. The rare earth alloy is used to perform gestation treatment to prevent gestation recession, and carry out gestation in the bag; the purpose of gestation is to refine tissue grains, improve the mechanical properties of castings, and enhance toughness. The lining is poured with a wet type, and the lining brick is a dry cast. Line brick, lining ingredient ratio (mass fraction): manganese iron 4.5%: steel cast iron steel; 0.6% scrap, silicon; (including the addition of gestation treatment in the bag); rare earth alloy, 0.5% (including in out The amount of secondary gestation treatment is carried out in the iron tank. The steel ball in the ball mill is a industrial consumable, because the steel ball itself is a part of the grinding to say that there is no loss after the steel ball work, it is obviously unlikely, in order to keep the grinding steel ball With, it should be noted that various factors affecting steel ball wear. Of course, pay attention to timely replacement of steel balls. In order to make up for the effects of steel balls on the effective effect, the mill works after a period of time to meet the aggressive effect of the ball mill. Regularly adding the cycle is to generally not exceed the total amount of 5 according to the proportion of steel ball wear and steel ball steel ball, if there is a special factor affecting the amount of steel ball wear, the cycle period It should also be adjusted accordingly. It should be noted that the above is the cycle of the ball mill equipment under normal production conditions. If special conditions also need to develop the corresponding cappere program to ensure the ability of the ball mill to ensure the ability of the mechanical work.
