Temperature Conditions of the Work of Matrix during Hot Pressing Steels with Glass Lubricant,

Abstract

The greatest heating of matrix/die is observed in the place of the transition of conical part to the calibrating mesh. The combination of high heating and large loads leads to the intensive wear of this zone of matrix/die. The basic heat shield of matrix/die from heating is reached as a result of applying a lubricating disk. When using this form of lubrication lowers the heating of matrix/die to 400 C and more. The value of the heating of matrix/die depends on the properties of the used lubricating disk, coefficient of drawing, velocity and method of pressure forging (with butt or without it). (Author)
