Vacuum furnace heat treatment of operational processes
Vacuum furnace heat treatment of operational processes 1. workpieces in a vacuum hardening, you should use a vacuum quenching furnace oil, this oil has a lower saturation vapor pressure. 2. Vacuum furnace maintenance should charge under vacuum or nitrogen status, avoid breathing normally when no...
Heat treatment furnace equipment
The heat treatment furnace equipment is old, the furnace lining has great heat, the heat treatment furnace wall temperature rises, the heat dissipation is more, the insulation performance is poor. The heat treatment process is too conservative, and the management of heat treatment furnace equipme...

Unattended Left May Lead To Major Destruction of Vacuum Brazing Furnace
Unattended Left May Lead To Major Destruction of Vacuum Brazing Furnace The cooling system is an important part of a vacuum furnace vacuum unit. Water should be kept clear, otherwise water temperature downtime. This is the system work is often overlooked. When unattended may lead to a significan...
Advantages of vacuum furnace compared with ordinary heat treatment furnace
The vacuum furnace completely eliminates the oxidation and decarburization of the surface of the workpiece during the heating process, and the clean surface of the non-metamorphic layer can be obtained. This is a great deal to improve the cutting performance of the cutting tools (such as the cutt...
Brazing diamond grits onto a steel substrate using copper alloys as the filler
Brazing diamond grits onto a steel substrate using copper alloys as the filler Surface-set diamond tools were fabricated by an active metal brazing process, using bronze (Cu-8.9Sn) powder and 316L stainless steel powder mixed to various ratios as the braze filler metals. The diamond grits were b...
