RQ3-25-9 Small Heat Treatment Carburizing Furnace Resistance Wire Heating
Introduction of heat treatment carburizing furnace:
Pit type furnace is cycle type furnace, apply to the pole, long axial parts heat treatment. The Wells of the furnace body is cylindrical, by special crane installed vertically within the charging heating workpiece. Pit type furnace is usually placed below the ground plane in the shop, also have placed above the ground plane, or each half of the under ground plane.
Main Performance Index of carburizing furnace:
1.1 carbon potential uniformity: ≤±0.05%CP;
1.2 carbon potential stability: ≤±0.02%CP;
1.3 carbide uniformity grade: ≤±1 grade;
1.4 Effective case depth tolerance: ≤±0.1mm for case depth≤1mm; ±5% for case depth: ≥1mm; (same bath material);
1.5 carbon potential control method: oxygen probe and PID regulation;
Characteristics of gas carburizing furnace:
1) Rational structure, uniform furnace temperature, small upper & lower temperature difference in working zone, especially applicable for heating and heat treatment for long axial work-piece.
2) Adopt energy-saving furnace lining, fast temperature rise, low empty furnace consumption, save more than 20% of energy compare with old product.
3) The control system can be equipped with normal control instrument or instrument with micro-processor program control according to actual need.
4) When needed during process, protective atmosphere can be fed into the furnace to realize little-oxidizing heating.
5) Each product is installed with safety interlock and over-temperature device to provide reliable and safe operation and use.
