The vacuum furnace is mainly for wire, copper wire, stainless steel wire and other special specifications, luminous material need protective atmosphere heat treatment equipment in the vacuum state.
One, furnace type structure:
The bright vacuum resistance furnace is a combination of furnace body, furnace, control system, vacuum pump, ammonia decomposition furnace.
1, the furnace body is channel steel and steel plate by welding, the furnace lining is made from light clay brick masonry, the heating element to hang in the refractory brick silk put aside, the heating element material for 0Cr25Ai5, into a spiral, insulation materials is the use of Shandong Luyang production of cotton fiber and vermiculite powder, shell table 50 DEG C lower than the temperature of the surface is less than or equal to
2, furnace, the device is equipped with a furnace tank device, furnace material for 1Cr18Ni9Ti, thickness as the delta 8 mm, stainless steel plate welding. At the bottom of the standard head connection.
Furnace upper is a thick steel plate is with a flange, water cooling device, in upper flange processing for type O, a U-shaped notch, installation sealing strip for sealing protection.
The furnace cover is at the bottom of the barrel body, a heat insulating box carbon steel has a delta of 30 mm thick stainless steel plate welding good. Fill insulation material.
The sealing of the furnace liner and the furnace cover is fastened with a variety of studs, and the air inlet and outlet are arranged on the plane of the furnace cover, and the vacuum pump is connected to the plane of the panel.
3, control system
Control part of the use of PID zero crossing automatic reactive power adjustment, no paper recorder, with Taiwan adjustment instrument operation, the temperature uniformity of 1, and the installation of a super temperature alarm device.
