Study Of Impulsive Corrosive Wear And Tear Of Two Kinds Of Steel In Hot Strong Alkaline

This paper studies the corrosion and wearing and tearing characteristic of high manganese steel and medium- chromium steel in hot strong alkaline and the ore pulp of aluminum, Ball mill welt select suitable materials basis of offering rationally for operating mode this, Assault and corrosion the wearing and tearing theory abundantly. Study and an assaults and corrosions and wears and tears the testing machine.Apply the machine and SEM and the cure of partly polar, analysis quantity the interaction of corrosion the wearing and tearing characteristic of high manganese steel and medium- chromium steel in hot strong alkaline and the ore pulp of aluminum. As the result shows, the percent of wearing increase in rate of all weightlessness, on the contrary, the rate of pure corrosion decrease. Wearing will increase the ability of corrosion, and wearing is the main reason of affect the ability of corrosion. The rate of weightlessness in affection of corrosion is higher than in pure wearing, which is make up the rate that is more than 50 percent. So the effect of corrosion impulse to wearing is the main reason of weightlessness impulsive corrosion. In conclusion, the anticorrosion of medium-chromium steel is better than high manganese steel in the environment in hot strong alkaline and the ore pulp of aluminum. So former is moresuitable than later form the operating mode of ball mill machine offering aluminum oxide factory.
