1. Features

1.1 The resistance electric melting furnace lining is composed of the superlight refractory

bricks and the ceramic fiber module material, which has a good heat preservation effect. The

wall temperature rise is ≤ 40℃.

1.2The resistance electric melting furnace adopts the Taiwan brand temperature controller with

PID control. The temperature control accuracy reaches ±5℃.

1.3 The resistance electric melting furnace is equipped with one thermal couple protected by the

silicon nitride outer pipe, and this thermal couple could directly measure the aluminum liquid.

3. Structure of electric crucible melting furnace

The melting furnace consists of the following three parts: furnace body, electrical heating and

control system.Furnace Shell: The furnace shell is made from steel plates and sectional steel

in a shape of a round column. The joining areas are closely welded.

Lining: For side wall, the lining of the side wall includes the silicate aluminum fiber block,

superlight 0.6g/cm3 refractory brick, and filling vermiculite powder. The heating components

are OCr27A17MO2 high-resistance alloy wires.For furnace bottom, it is built with once-forming

castable material with a long service life and a high strength.

Heating System:

a)heating components—high-resistance wires (1 zone control);

Control system: temperature controller (imported from Taiwan, 2 pieces), electronic power regulator,

contactor, relay.Temperature sensing component: thermal coupling (2 pieces in together, 1 for

measuring the hearth atmosphere temperature and another for measuring the molten aluminum temperature)
