Product introduction
Silicon carbon rod is used as heating element in the atmosphere furnace of ventilated protective sintering furnace, double shell structure and intelligent temperature control system are adopted, phase shifting trigger and silicon controlled, inner liner is made of temperature-resistant and pressure-resistant alloy material, and furnace door is equipped with circulating water cooling to ensure reliable sealing of furnace door and furnace gall.
Main uses and scope of application:
It is applied to vacuum treatment of electronic components, new materials and powder materials.
Main functions and characteristics:
1. The inner liner is made of temperature-resistant and pressure-resistant alloy material, which can vacuum up to - 0.1 MPa, and can lead to a variety of protective atmosphere.
2. The furnace uses alumina polycrystalline fiber material, which has good thermal insulation, durability, high tensile strength, no impurities, high purity, better energy-saving effect than domestic fiber materials, and high-quality silicon-carbon rods are used as heating elements.
3. Through our software and computer interconnection, we can realize the functions of remote control, real-time tracking, history recording and output report forms of single or multiple electric furnaces, and install paperless recording device to realize data storage and output.
4. Overvoltage automatic relief, over-temperature alarm and power failure, leakage protection, safe and reliable operation;
