Several methods of out – of – furnace processing of liquid metal are considered in order to reduce gas pores and non – metallic inclusions in the liquid alloy, to develop the mode of liquefaction of alloys and to process them, to obtain high-quality cast products. After cleaning the alloy from gas pores and nonmetallic inclusions, the alloy was poured into a sand – clay mold slightly larger than the size shown in the drawing [14 – 17].
RESULTS
Production of high – quality cast products from 35XGCL steel alloys and reduction of gas pores and nonmetallic inclusions in its content, liquefaction mode of alloys and their processing technology were developed, and high – quality cast products were casted (Pic. 3. 4).
