Description

Smelting furnace for cast iron

Technical Field

The utility model relates to the field of smelting furnaces for cast iron, in particular to a smelting furnace for cast iron.

Background

The heating mode in which heat generated during combustion of the fuel or heat generated by the resistive element is directly transferred to the charge is called a direct heating mode. Its advantages are high heat efficiency and simple structure. The disadvantage is that the harmful impurities contained in the combustion products have an adverse effect on the quality of the charge; harmful gases volatilized from the furnace burden or the covering agent can corrode the resistance element, and the service life of the resistance element is reduced; in the fuel combustion process, the content of excessive air in combustion products is high, so that metal burning loss is large in the heating process, and two types of indirect heating modes exist. The first type is that combustion products or electrified resistance elements do not directly heat furnace burden, but heat transfer intermediaries such as radiant tubes are heated first, and then heat is transferred to the furnace burden in a radiation and convection mode; the second type is to apply alternating current to the coil to generate an alternating magnetic field, so as to heat the furnace burden in the magnetic field by induction current, and the heating elements such as the induction coil and the furnace burden are separated by furnace lining materials. The indirect heating mode has the advantages that combustion products or electric heating elements are separated from the furnace burden, no harmful influence is generated between the combustion products or the electric heating elements and the furnace burden, the quality of the furnace burden is kept and improved, and the metal burning loss is reduced. The induction heating mode also has stirring effect on the metal melt, so that the metal melting process can be accelerated, the melting time is shortened, and the metal burning loss is reduced. The disadvantage is that heat cannot be directly transferred to the burden, and compared with a direct heating mode, the heat efficiency is low, and the structure of the furnace is complex.
