Abstract

The invention relates to a metal melting furnace and a metal melting method. The metal melting furnace comprises a heating furnace, a melting furnace erected on the heating furnace, a heat accumulating type combustion system, a feeding device and a circulating melt pumping and supply device erected on the melting furnace. The heat accumulating type combustion system not only can heat the heating furnace, but also can store high-temperature gas in the heating furnace on a heat accumulator, so that the heating efficiency of the heating furnace is increased. The residual heat of the heat accumulator is led to the feeding device and is used for heating granular or flaky metal materials thrown in the feeding device. Waste heat can be sufficiently recovered, and the preheated metal materials can be further pushed into the melting furnace by the feeding device, and heated and melted into liquid. Therefore, heat energy can be fully recovered, time spent on the sequent procedure of melting the metal materials into the liquid can be largely shortened, the heat energy (fuels) can be largely saved, and the whole process for preheating, heating and melting the metal materials and filling the liquid metal into a die is time-saving, fluent and successive and the metal melting furnace has high safety.

Description

technical field

[0001] The present invention relates to a "metal melting furnace" and a "metal melting method" for preheating granular or flake metal materials with waste heat generated by a melting furnace, and then further heating and melting the metal materials. Background technique

[0002] The method of melting metal in the prior art is mainly to put metal ingots, bars or scraps directly or preheated into a boiler for heating, and after the metal materials are melted and completely mixed, the ingots in the boiler are then heated. The liquid metal is injected into the cavity of the mold to solidify and form.

[0003] However, the above-mentioned existing steps of casting metal products have the following problems: firstly, since the ingot-shaped or bar-shaped metal material is directly put into the boiler for heating at normal temperature, it takes a long time for heating to reach the state of melting , the process is very time-consuming; secondly, because the liquid me...

Embodiment Construction

[0053] see figure 1 As shown, the metal melting furnace of the present invention includes a heating furnace 10 , a melting furnace 20 , a regenerative combustion system 30 , a feeding device 40 , a stirring rod 51 and a circulating pulping and soup feeding device 52 .

[0054] A heating chamber 11 is formed inside the heating furnace 10 .

[0055] The melting furnace 20 is erected on the heating furnace 10 , and the melting furnace 20 includes a furnace body 21 and a cover plate 22 . The furnace body 21 is placed in the heating chamber 11 of the heating furnace 10 , and the furnace body 21 can be heated by making the heating chamber 11 of the heating furnace 10 surround the furnace body 21 . Moreover, a melting zone 211 , a stirring zone 212 and a soup feeding zone 213 are separated in sequence by two heat-resistant partitions 23 inside the furnace body 21 . The heat-resistant partition 23 is provided with a plurality of perforations 231 , so that the melting zone 211 communic...
