Features: ★ mainly to solve the material structure with the general methods are difficult to access, particularly suitable for the connection of aluminum, titanium content of more super alloy, stainless steel and other metal materials, as well as graphite, ceramics and other non-metallic materials. ★ round furnace, by controlling the output of the regulator to regulate the temperature, complete the set requirements of process parameters, and with the corresponding display record. Run the vacuum system of the implementation of automatic / manual control, displayed by the gauge vacuum. Controlled by a programmable logic controller implementation process, the entire system with automatic alarm function. The main technical parameters: Model effective working zone size mm maximum temperature ℃ Limit vacuum degree of temperature uniformity ℃ Pa pressure rise rate Pa / h Heating power kW installed furnace capacity kg air-cooled pressure bar BOK-80 450 × 300 × 300 1350 6.67 × 10 -4 ± 3 0.3 80 100 ≤2 BOK-90 600 × 400 × 300 1350 6.67 × 10-4 ± 3 0.3 90 200 ≤2 BOK-120 1100 × 600 × 600 1350 6.67 × 10-4 ± 3 0.3 120 300 ≤ 2 BOK-150 900 × 700 × 500 1350 6.67 × 10-4 ± 3 0.2 150 500 ≤2 BOK-420 1000 × 1000 × 1000 1350 6.67 × 10-4 ± 3 0.2 420 1000 ≤2
