Product introduction of box vacuum furnace



Box vacuum furnace can be professionally designed and manufactured according to customer requirements.

First, the use of box vacuum furnace This series of vacuum resistance furnace (hereinafter referred to as electric furnace) is a periodic operation furnace, mainly used for vacuum bright annealing of various metals, can also be used for other heat treatment.
2. Brief introduction of the structure of box vacuum furnace The furnace shell is welded by section steel and steel plate, and the interior is built with ultra-lightweight high-alumina foam bricks. The insulation layer is made of aluminum silicate refractory fiber and diatomaceous earth (or vermiculite powder). Bulk material structure to improve the insulation performance of the furnace body. The heating element is placed on the wire brick, and it has a small wire hook to make it. Inside the furnace, there is a vacuum tank welded with stainless steel plates. The workpiece rack to be processed can be placed in the tank. The top of the vacuum tank is filled with a refractory fiber-filled furnace for heat preservation. The vacuum pipeline is equipped with a protective gas valve, a bleed valve and a disc valve for use during operation. A vacuum gauge and a spare port are installed at one end of the pipe (for the user to install a vacuum gauge). A mechanical pump with an electromagnetic vent valve is connected to the vacuum tank through a plastic hose. Damage, the upper part of the vacuum tank is provided with a cooling water jacket. After the vacuum tank is out of the furnace, the user can configure a cooling bucket for cooling as required. The furnace lid and furnace can be lifted by the user.
Third, the box vacuum furnace control system uses PID zero-crossing trigger SCR, automatic power adjustment intelligent meter temperature control.
