Uses:For small and medium quantities of mechanical parts in the control atmosphere hardening, tempering, carburizing, carbon ammonia permeation treatment, can be used for brazing, sintering, solid solution treatment. Such as standard parts, bearings, gears, drive chain, hand tools, springs, Case, gossamer, vernier caliper, minor equipment, small molds, cutlery, various types of textile machine needles, needles and other heat treatment. Configuration on the feeder, before and after the washing machine, hardening furnace, quenching tank, furnace, protective atmosphere generators and electrical control system can be composed of mesh resistance furnace automatic production lines. Quenching furnace temperature: 750 °C -1150 °C Furnace temperature: 160 °C -750 °C The composition of each production line heat treatment according to the quality of the user requirements for the design and composition.Features:Mesh belt running, variable speed, easy maintenance. Heating element (electric radiant tube), can not completely shutdown to replace. All fiber lining, light weight, good insulation. Gas furnace with forced circulation device, workpiece heating temperature, heat treatment and smooth surface, uniform hardness, deformation. Complete automatic control system. Temperature by a PID regulator, gas furnace carbon potential of carbon from the oxygen and carbon control of the first monitoring device or computer controlled, high precision, process parameters and stability.
