Detailed introduction


Technical Details:

The hard alloy high-vacuum welding furnace adopts infrared radiation heating method, 30 – steps programmable temperature control, and uses an N-type thermocouple. The body is of Alumina (1500) microcrystalline fiber material, which has a good heat preservation effect that can improve the heating efficiency of the equipment,   and also extend the service life of the heating element. The furnace tube adopts a high-purity quartz tube, which has less airflow under a high vacuum,   good light transmittance, and can withstand rapid cooling and heating. It can reach up to 900℃ under a high vacuum, with a balanced temperature area, and low surface temperature. It has the advantage of fast temperature change, energy-saving, etc. 

The control part adopts   PLC intelligent module combination control with the provision of automatic/semi-automatic/manual operation. The control system integrates   AI518P temperature controller, ZDF-5227 compound vacuum gauge, and molecular pump controller. It adopts a 10-inch MCGS LCD touch screen operation.
