Abstract

The technological scheme for forging of heavy ingots by means of special figured block head is represented in the article. Its influence during the ingot drawing is described. Appliance of specialized tools and cooling-down provided receipt of metal required characteristics and positive results in ultrasonic testing. Combined technological solution gives the opportunity to extend the critical forgings assortment.
