Abstract

The invention relates to a metal melting method. A heating furnace, a smelting furnace erected on the heating furnace, a checker chamber combustion system, a feeding device and a cycle slurry pumping and fluid feeding device erected on the smelting furnace are included in the method. The checker chamber combustion system can heat the heating furnace, store high-temperature gas in the heating furnace into a regenerator, improve the efficiency of heating the heating furnace, guide waste heat of the regenerator into the feeding device and heat granular or sheet-like metal materials charged into the feeding device; as a result, the waste heat can be fully recycled, and the preheated metal materials can be further pushed into the smelting furnace by the feeding device and heated and melted into liquid. Thus, heat energy can be fully recycled, the time and heat energy (fuel) required for subsequently melting the metal materials into liquid can be substantially decreased, and the metal materials are overall preheated, heated and melted; time is shortened in the process that liquid metal is injected into the mould, and the process is smooth and can be conducted continuously, and high safety is realized.

Description

Technical field [0001] The invention relates to a "metal melting method" in which a granular or sheet metal material is preheated by the waste heat generated by a melting furnace, and then the metal material is further heated to melt the metal material. Background technique [0002] The method of melting metal in the prior art mainly involves directly or preheating the metal ingots, bars or scraps before putting them into a boiler for heating. After the metal materials are melted and completely mixed, the ingots in the boiler Liquid metal is injected into the cavity of the mold to solidify and form. [0003] However, the problem with the above-mentioned existing steps of casting metal products is that: firstly, since the ingot-shaped or bar-shaped metal material is directly put into the boiler for heating at room temperature, it takes a long time to reach the molten state. , The process is very time-consuming; secondly, because the liquid metal is injected into the mold by manual ...
