In the conventional method of supplying molten metal for casting, a metal raw material is melted in a melting furnace and made into a molten metal, and then an ingot, that is, an ingot is formed. The ingot is made by solidifying molten metal by injecting it into a certain mold, and it becomes a material such as casting, forging, and rolling.

Therefore, a casting company for molding a general product first melts the ingot carried from a casting company casting the ingot into a remelting furnace and uses it as a molten metal.

However, according to the conventional molten metal supplying method for casting, since the molten metal is melted as a molten metal after the molten metal is converted into an ingot, the environmental problem and the energy cost of the melting furnace are duplicated, and a similar equipment is invested redundantly Problems, shipping cost and time required for ingot transportation.

Therefore, it is an object of the present invention to provide a casting molten metal supplying system which can deviate from a conventional method of using an ingot as a medium of a casting material and can supply the molten metal of the melting furnace directly to the casting company.

In order to accomplish the above object, the present invention provides a molten metal supplying system for a casting, comprising: a molten metal supply unit having a molten metal furnace installed on the ground and a molten metal furnace rotation driver for supplying molten metal in the molten metal furnace; A molten metal storage unit installed in the ground with the material supply unit different from the workplace and having an electric heating / heating furnace for storing the molten metal therein; And a ramp for connecting one end of the molten metal to the melting furnace of the molten metal supply unit and the other end of the ramp for connecting the molten metal to the electric heating apparatus; And a ladle for containing the molten metal drawn from the underground electric heating apparatus and a ladle elevator for raising and lowering the ladle to the ground.

Here, the casting molten metal supplying system may include a molten metal level sensor for sensing a high level of the molten metal stored in the electric heating mantle; And a controller for controlling the solenoid rotary actuator to raise the solenoid when the detection signal of the molten liquid level sensor is received.

At this time, the casting molten metal supplying system includes a molten metal chute installed around the lower end of the electric insulating furnace; And a ground temperature sensor provided in the molten metal chute. The control unit may be configured to control the solenoid rotating actuator to raise the melting furnace when receiving the sensing signal of the ground temperature sensor.

Further, the casting molten metal supplying system may further include an alarm generator installed on at least one side of the electric heat keeping furnace and the melting furnace, and the controller may be configured to operate the alarm generator when receiving the detection signal have.

The casting molten metal supply system may further include a manual breaker provided on the side of the electric heating apparatus, and the control unit may be configured to control the spin furnace rotary actuator to stand the melting furnace when receiving the signal of the manual breaker It is possible.

As described above, according to the molten metal supplying system of the present invention, the molten metal in the molten metal bath is directly transferred between the molten metal supplying unit and the molten metal storing unit, which are different from each other, through the liquid transfer bath, It can be used as a molten metal.

Therefore, it is possible to solve the problem that the conventional problem of the melting of the molten metal after the molten metal is melted after the molten metal is converted into the ingot and the energy cost of the melting furnace is duplicated, as well as the problem of overlapping investment of similar equipments, The problem of time generation can be solved.
