Carbide vacuum sintering furnace

Cemented carbide vacuum sintering furnace is mainly used for sintering, vacuum heat treatment, high temperature vacuum sintering. Suitable for sintering of stainless steel base, hard alloy, high temperature alloy, high specific gravity alloy, ceramic material, magnetic material, carbide, boride, nitride, oxide and intermetallic compound.

The use of vacuum sintering of cemented carbides excludes hydrogen from hydrogen and other people with its impact on the gas, the atmosphere can be stable, to ensure that WC-like compound carbide to obtain excellent performance. In addition, carbide vacuum sintering furnace also short product life cycle, flexible process control features, so the trial of cemented carbide, shaped carbide sintering and small batch of some products have been widely used in small plants. Vacuum sintering temperature is generally below 1500 ℃, the vacuum sintering furnace is usually designed to have a maximum temperature of 16 ℃. At present, the vacuum sintering furnace used in China mainly adopts multi-layer carbon felt insulation screen, while the heating element uses graphite bar. The following 50 liters horizontal vacuum furnace, for example, describes how to calculate the power of the heating element and its commonly used structural design. 1 heating body power calculation Thermal equilibrium method of calculating power, involving more factors, a variety of heat and heat loss is difficult to accurately estimate the calculation results are generally for reference only. The empirical method is based on mathematical statistics and multiple regression analysis of a large number of vacuum furnaces in use, and the result is more accurate. P 2,06 F076 (win, ‘on the formula 1) a vacuum furnace rated power (KW); F an effective working surface area (dIT12); T a rated temperature (℃). The available space for a 50 liter vacuum furnace is 2.5 x 2 sxsdm, with F = 92.5 dm2 and T = 16 ° C for the above formula, with P = 61 .Skw.
