Pouring melting furnace

Abstract

The invention relates to a pouring melting furnace comprising a shell, a melting chamber and a combustion chamber. The melting chamber is of a closed barrel-shaped structure; an observing port is arranged at the side wall of the top of the melting chamber; the lower end of the melting chamber is arranged in the combustion chamber; a feeding port is arranged at the side wall of the combustion chamber; a slag discharging port is arranged at the bottom of the combustion chamber; ports which are corresponding to the observing port, the feeding port and the slag discharging port are formed at the shell; a chimney which extends out of the shell is arranged at the top of the combustion chamber; the outer wall of the melting chamber outside the combustion chamber is covered with a thermal insulating layer; and a fire-resisting thermal-protective layer is arranged among the thermal insulating layer, the combustion chamber and the shell body respectively. The pouring melting furnace is characterized in that a smoke storing chamber is formed between the top of the shell and the melting chamber; a smoke channel which is communicated with the smoke storing chamber is arranged between the thermal insulating layer and the fire-resisting thermal-protective layer; a baffle is arranged at the bottom of the smoke channel and fixed at the side wall of the combustion chamber. The pouring melting furnace has the advantages of continuous pouring, convenient and rapid process, safety, reliability and improved qualified rate of casting molding.

Description

technical field [0001] The invention relates to a melting furnace, in particular to a pouring melting furnace, which belongs to the field of casting pouring. Background technique [0002] At present, when manufacturing metal castings, it is necessary to heat and melt the metal raw material in a melting furnace with a crucible, then take out the crucible, pour it, and shape it through a mold. Like this, the crucible must be taken out every time pouring, because the temperature of the crucible is extremely high, the operation is very dangerous, and the high temperature is harmful to the human body. In addition, when the crucible is taken out, a large amount of high-temperature gas will be discharged, which not only pollutes the environment, but also causes unnecessary heat loss and wastes energy. Contents of the invention [0003] The object of the present invention is to provide a pouring melting furnace capable of continuous pouring, convenient pouring, safe and efficient...

Problems solved by technology

In this way, the crucible must be taken out every time it is poured. Because the temperature of the crucible is extremely high, the operation is very dangerous, and the high temperature is harmful to the human body.

In addition, when the crucible is taken out, a large amount of high-temperature gas will be discharged, which not only pollutes the environment, but also causes unnecessary heat loss and wastes energy.
