Pusher Reduction Equipment

Overview and Principles

 Powdered material deoxidization/annealing equipment of this series produced by, is primarily applied to the deoxidization/annealing of metallic oxide powders, also to the calcination of salts and the metallurgy and sintering of powders.

 The entire equipment is consisted of three major components, furnace, material pushing device and temperature regulating system. Heating elements are distributed on and beneath the Muffle device, installed as draw-pull type of two lateral sides of the furnace connecting through with each other, convenient for installation and maintenance.

 Both front and rear material passing ends are designed with bi-door furnace for constructing gas-replacing room, decreasing the gas exposed points and consuming, and greatly improving the steady of product quality and production security.

 Each stage is equipped with closed-loop control system consisted of thermocouple, digital-displaying type intelligent PID regulator, and pressure and power regulator, achieving in precisely auto-controlling temperature (temperature control precision ±5℃). Pusher’s pushing force is set with monitoring, PLC + touch screening control, simplified and clear operation, and auto-checking procedure guarantee device safely performing.

Innovative Technology:

Wet powder directly enters in deoxidization reaction, lower oxygen content. The gas pressure inside furnace is controllable, higher powder quality.

 Temperature control system is equipped with thermocouple, digital-displaying type intelligent PID regulator, and controllable silicon, forming closed-loop control system, achieving in precisely auto-controlling temperature.

Performances and Advantages

　       possesses several key core technologies and proprietary intellectual property rights.

Own patent technologies (Patent No. ZL200730070496.0). Uniformed furnace structure improves its temperature holding property and is convenient for maintenance.
