Product Description:
Precision shaft furnace adopts top open door, high quality resistance wire as heating element, double shell structure and intelligent temperature control system. The furnace uses alumina polycrystalline fiber material, which has good thermal insulation and energy saving.
Main uses and scope of application:
Special equipment for sintering, melting, analysis and production of ceramics, metallurgy, electronics, glass, chemical industry, machinery, refractories, new materials development, special materials, building materials, metals, non-metallic materials tempering, annealing and other heat treatment, as well as quenching, solid melting and aging treatment of aluminium alloys.
Main functions and characteristics:
1. Alumina polycrystalline fiber material is used in the furnace, which has good thermal insulation, durability, high tensile strength, no impurities, high purity and obvious energy saving effect.
2. High quality alloy wire OCr27Al7Mo2 is used as heating element.
3. The shell can be designed with Q235/304 stainless steel and the inner liner can be made with 310S stainless steel.
4. Turn on power-off and leakage protection, and alarm over-temperature to ensure the safety of the equipment.
5. Our software devices are connected with computers through 485 or USB interface, which can realize remote control, real-time tracking, history recording and report output of single or multiple electric furnaces, and can install paperless recording device to realize data storage and output.
6. The vacuum system, inflation system and temperature control system can be programmed by touch screen operation. The operation is simple, convenient and accurate.
