Product Description

Use:
SLR series mesh-belt sintering furnace (also known as mesh-belt powder metallurgy sintering furnace or powder metallurgy continuous sintering furnace) is mainly used in the sintering of copper-based and iron-based powder metallurgical product, composite material and bimetallic material. also can be used in the brass soldering and bright heat-treatment of cooling accessories of auto filter, refrigerator, air-conditioner, stainless steel parts, carbon steel parts, brass parts and red copper parts.

Features:
1) The complete equipment is composed of furnace body, mesh-belt transmission system, temperature control system, and atmosphere control system.
2) The furnace body is composed of feeding section, pre-sintering section, sintering section, slow cooling section, and discharge section.
3) The pre-heating section adopts heating resisting metal muffle, which is divided to three sectors to control temperature and heated by resistance wire or gas. 
4) The sintering section adopts muffle made of silicon carbide combining with silicon nitride (SiC+Si3N4), which is divided to three sectors to control temperature and heated by silicon carbide rod (SiC). 
5) The mesh-belt transmission system is composed of imported SUS314 high-temperature resisting mesh-belt and transmission devices. 
6) The running speed of mesh-belt can be adjusted by frequency converter. There is a speed sensor with digital display to readout the speed of mesh-belt.
7) The temperature control system, which forms closed loop control system to realize automatic accurate temperature control, is composed of thermocouple, intelligent PID regulator with digital display and silicon controlled rectifier.
8) The gas flow meter displays the flow rate of protective atmosphere. The rates of all kinds of atmosphere can be adjusted according to process requirement. There is an under pressure alarm system for atmosphere. In case of the pressure of atmosphere is under the setting value, the system gives out sound and light alarms. 
9) The temperature of cooling water is automatically controlled by the make and break of magnetic valve controlled by temperature controlling elements. 
10) The electric control cabinet is completely sealed to guard against conductive dust. The heat exchanger or air conditioner in it can lower the working temperature of electrical components so as to raise the reliability of controlling system.
