FEATURES OF OBTAING OF METAL CHARGE MIXTURE FROM A WASTE OF MACHINERY PRODUCTION ENTERPRISES
This article is devoted to investigation of possibility of obtaining the charge mixture blanks for foundry production and metallurgy, using metallurgical slag and shavings of aluminum alloy V95, by aluminothermy. Yield and chemical composition of the metal phase formed as a result of the exothermic reaction were used as the monitored parameters. To control these parameters the chemical and fractional composition of charging materials and their influence on the properties of thermite mixtures were studied. Experimentally determined the optimal ratio of the size and design of refractory equipment. Determined the interrelation of contact conditions of melt with refractory rig, during exothermic reaction and in process of filling a mould on the chemical composition of the alloy. The research led to the conclusion about the possibility of obtaining not only charge mixture blanks with specific properties, but also casting parts for irresponsible destination made from steel alloys using the specified materials.
