This box-type electric furnace can heat materials to very high temperatures. For
example, a carbon material graphitization electric furnace can heat materials to
over 2500°C.Powder
Metallurgy Gear Manufacturing Process The direct heating resistance furnace
can be made into a vacuum resistance heating furnace or a protective gas
resistance heating furnace. In powder metallurgy, it is often used for sintering
tungsten, titanium, silver and other products.vacuum-brazing-repair-method-for-cracks
When heating with direct heating box-type electric furnace, please pay attention
to: ① In order to heat the material evenly, the conductive cross-section and
conductivity of each part of the material are required to be consistent;Vacuum
brazing of ceramic and metal materials ② Since the resistance of the
material itself is quite small, in order to achieve the required electric
heating power, the working current is quite large, so the contact between the
power-transmitting electrode and the material should be good; In order to avoid
arcing and burning of materials, the resistance of the power transmission bus
should be small to reduce circuit losses;Application
example of vacuum heat treatment technology in mold ③When supplying
alternating current, the short network should be configured reasonably to avoid
excessive inductance and low power factor.
