PROTECTION OF STEEL BILLETS FROM OXIDATION DURING HEATING AND PROCESSING HEAT TREATMENT UNDER PRESSURE
Abstract
Analyzed existing methods nonoxidative heating under pressure treatment and heat treatment. Of these, two are tested and selected to give the best protective effect at the lowest cost and do not require scarce equipment, supplies and raw materials – time high-temperature coating and heating of billets in baths of molten glass. Selected composition coating deletes itself capable of performing the role of technological lubrication by pressure treatment. The results of laboratory and factory tests. Recommended consistent application of heat in the glass melts in forging and stamping, followed by protection of finished products temporary cover during the heat treatment that allows you to create a solid nonoxidizing manufacturing process of high-quality products.
