Manufacturnig techniques of aluminum protectors of underwater parts DSSP intended for protection

The paper is devoted to manufacturing process of aluminum protectors for electro-chemical protection of underwater steel parts DSSP (Deep-water smelt in the induction furnace and quality of them depends on manufacturing of charge a material and a material lining as well as on sequence of their input in a furnace, speed of fusion, casting liquid metal and cooling For cheking the segregation it is recommended to merge aluminum molding in the metallic form for maximum short time. Technological process of manufacturing of aluminum protectors is made in foundry installation. The matter of this way is,that liquid metal in regular intervals and without interruption flows from one end to cooled form crystallizer,and from other end is pulled out by means of the special mechanism preparation with round section .
