Abstract

The invention relates to a heater, specifically to a heater for a vacuum hot-pressing furnace. The interior of the heater is a cavity. A carbon felt insulation layer is arranged inside the heater housing. On the four side wall surfaces inside the heater, a vertical heating plate and the heater housing are connected through an electrode rod and a supporting rod. On the upper wall surface and the lower wall surface inside the heater, a horizontal heating plate 1 and a horizontal heating plate 2 are connected with the heater housing through the electrode rod and the supporting rod. Thus heating efficiency is improved, and heating time is shortened.

Description

technical field [0001] The invention relates to a heater, in particular to a heater used in a vacuum hot pressing furnace. Background technique [0002] Metals, ceramics and some refractory metal intermediate compound powders need to be heated and sintered to become materials with certain density and certain mechanical properties. The powdery material is placed in a high-carbon mold in a vacuum and protective atmosphere, and when it is heated to a softened state at a high temperature, it is molded under pressure. Vacuum hot pressing furnace combines vacuum, hot pressing forming and high temperature sintering together, and is mainly suitable for high temperature hot forming of new materials such as powder metallurgy and functional ceramics. With the leap of science and technology, the high-temperature sintering process under normal pressure can no longer meet the needs of new material production. So a new process of vacuum hot pressing gradually appeared. [0003] At pres...
