In order to address the above problem, electric heating casting ladle preheater of the present utility model, comprise electric cabinet, main body rack, be arranged on the elevator chamber on main body rack and the drive unit in order to drive elevator chamber to slide up and down along main body rack, on described elevator chamber, be fixed with lifting support, the below of described lifting support is connected with insulation cover, and the lower surface of described insulation cover is provided with the electric heater unit by electric cabinet control.
For the ease of driving elevator chamber, lifting support, insulation cover and electric heater unit, electric heating casting ladle preheater of the present utility model, described drive unit comprises the gearbox being connected by the motor of electric cabinet control, with electric machine main shaft and is separately positioned on two sprocket wheels of main body rack top and bottom, between described two sprocket wheels, be provided with chain, described chain is fixedly connected with elevator chamber, and the sprocket wheel of described main body rack bottom is fixed on the output shaft of gearbox.
Electric heating casting ladle preheater of the present utility model, another mode of described drive unit is cylinder, and described cylinder is provided with push rod, and the top of described push rod is fixedly connected with elevator chamber.
Electric heating casting ladle preheater of the present utility model, is provided with the chain sling that is connected use between described lifting support and insulation cover.
Electric heating casting ladle preheater of the present utility model, described electric heater unit is squirrel-cage heater or resistance band heater.
The beneficial effect that the utility model is obtained is: (1) is simple in structure, and maintenance cost is low; (2) by electric heater unit, casting ladle is carried out to preheating in thermal-radiating mode, compared with existing combustion type preheating method, can not damage the flame retardant coating of casting ladle, greatly extended the service life of casting ladle and flame retardant coating; (3) drive elevator chamber, lifting support, insulation cover and electric heater unit to carry out lifting by motor or cylinder, whole elevating mechanism is simple in structure, good reliability and be easy to control.
