Category：Vacuum brazing furnace
Applications：Cemented Carbide Tool industry, Natural diamond, artificial single crystal, PCD/PCBN ceramic materials, etc. Ideal product for high-temperature sintering, high-vacuum welding of metal materials, annealing, degassing, and quality inspection for scientific research institutes and industrial and mining enterprises.
Main Features：Heat zone size: 400mm. Max. temperature: ≤1000℃. Ultimate vacuum: 6×10-4Pa. Furnace tube size Outer diameter 200/inner diameter 190/length 600mm. The equipment occupies less space, is easy to operate, and has high efficiency. Good welding quality, high strength, and strong stability. This equipment only needs 10-13 minutes for the vacuum to reach 10-3 Pa, 15-20 minutes for the vacuum to 10-4 Pa, and the ultimate vacuum is 10-5 Pa. This equipment only needs 120-150 minutes to process the products (including vacuuming, heating, cooling, and finished products.
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.
