Technical Features

Furnace Lid and the furnace pot can use the workshop Overhead Crane to lift out the entire vacuum nitriding pot for natural air cooling or forced rapid cooling in a pool, to facilitate loading and unloading of workpieces. To improve Production Efficiency , you can order two vacuum nitriding pots for alternate continuous operation. Nitrogen Protected Pit Type Tempering Furnace above 60KW is divided into multiple zones for temperature control, High Precision designs and distributes power. It adopts multiple sets of microcomputer program temperature control electric cabinets, Automatic displays the measured furnace temperature and nitrogen protection status, calculates Liter heating slope temperature values and set values, provides over-temperature alarm and Automatic process curve recording. It can set 8-segment process curves, with a temperature control accuracy of ±1℃.

Nitrogen Protected Pit Type Tempering Furnace can perform rapid in-furnace Cooling System , which can be proposed when placing an order. After the hot nitrogen inside the nitrogen-protected furnace is drawn out of the furnace, the rapid nitrogen circulation receives heat to reduce the nitrogen temperature, and cold nitrogen enters the tank's rapid cooling circulation system.
