Method for hot shaping a workpiece and agent for reducing the heat emission
First Claim
1. A process for hot shaping through solid-blank forming a workpiece or raw material of metal or of an intermetallic compound at a temperature of higher than about 1000°
- C., wherein the process comprises(a) at least partially coating a surface of the workpiece or raw material with a coating agent that comprises
1) an oxide phase,
2) at least one of an additive and an adhesive, and
3) at least one liquid component at a temperature of from more than about 100°
C. to approximately 200°
C.,(b) allowing the coating thus applied to solidify,(c) subsequently preheating with through-heating the coated workpiece or raw material to deforming temperature and transferring same to a shaping device, and(d) processing the workpiece or raw material with the shaping device into a formed body or a rolling product.

Abstract
A process for hot shaping a workpiece of metal or an intermetallic compound at a temperature of higher than about 1000° C. The method comprises at least partially coating the surface of the workpiece with a coating agent that comprises an oxide phase and an additive and/or an adhesive before processing the workpiece into a formed body or a rolling product. A coating agent for reducing the heat emission from the workpiece comprises a predominant amount of an oxide phase. This abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
