The electric control part of the electric heating furnace of the copper carving mold shell

The electric control part of the electric heating furnace of the copper carving mold shell

The electric control part mainly includes two parts: temperature control and operation. Temperature control adopts domestic digital display meter and AC contactor to implement common position control. It is also equipped with a recorder to record the complete process curve and can alarm over temperature; the operation adopts buttons and light display to realize the on and off of the heating element and the lifting of the furnace door. Action control, with interlocking device, safe and reliable. (This furnace type electric control can be equipped with PID intelligent control cabinet)

Bronze Carving Mold Shell Electric Heating Furnace Door

The furnace door device is composed of a furnace door, a furnace door lifting mechanism and a furnace door pressing device. The furnace door shell is welded by section steel and plate to form a firm frame structure, and the interior is laminated with refractory fiber pressing modules, which require good heat preservation performance and light weight. The lifting device of the furnace door adopts an electric device, which is mainly composed of a furnace door frame, a furnace door lifting beam, a hoist, a sprocket, a transmission shaft and a bearing, etc. The furnace door is raised and lowered by a hoist. The furnace door pressing device adopts the domestic advanced spring-type pressing structure. When the furnace needs to be lifted, the weight of the furnace door automatically loosens the furnace door through a lever, and moves horizontally for a certain distance and then rises. When the furnace door is lowered into place, the furnace door When it is put down on the pulley on the trolley and needs to be compressed, the elastic force of the spring will move the furnace door horizontally into the compressed and sealed state through the lever. The pressure device of this structure makes the fiber plane on the furnace door and the furnace mouth cotton There is no friction between them, and it has the characteristics of good safety performance and long use mission. The lifting of the furnace door is electrically controlled, equipped with interlocking control, that is, after the furnace door is opened slightly, the heating element is automatically cut off, and the power supply of the heating element is restored after the furnace door is closed in place.
