Description
Technical Field
The utility model relates to a metal smelting field particularly, relates to a large-tonnage smelting furnace.
Background
Smelting of metals is to change the metals from a combined state to a free state. A common smelting method comprises the following steps: the metal oxide is reacted with a reducing agent such as carbon monoxide, hydrogen or the like at a high temperature. The smelting principle is as follows: 1. reduction method: smelting the metal oxide (co-heating with a reducing agent) into free metal; 2. substitution method: smelting the metal salt solution (added with active metal) into free metal; among them, pyrometallurgy, also known as dry metallurgy, involves heating ores and necessary additives together in a furnace to a high temperature, melting them into a metal liquid, producing the desired chemical reaction, separating out the crude metal, and then refining the crude metal. Hydrometallurgy uses aqueous solutions of acids, alkalis, and salts to chemically extract the desired metal components from ores, and then uses aqueous solution electrolysis to prepare metals. The method is mainly applied to low-position ores which are difficult to melt or are in micro-powder form. At present, 75% of the zinc and cadmium in the world are produced by roasting-leaching-aqueous solution electrolysis. This method has largely replaced the traditional pyrometallurgical zinc smelting process. Other metals which are difficult to separate, such as nickel-cobalt, zirconium-hafnium, tantalum-niobium and rare earth metals, are separated by adopting a new method of hydrometallurgy technology, such as solvent extraction or ion exchange, and the like, so that the remarkable effect is achieved.
The smelting furnace is equipment for melting metal ingots and some waste metals, adding necessary alloy components, and smelting the metal ingots and the waste metals into required alloy through operations of slagging-off, refining and the like.

② the ratio of the surface area of the molten pool to the depth of the molten pool should be as small as possible;
③ the temperature of the metal in the molten pool is uniform;
④ the furnace has high thermal efficiency;
⑤ the process is convenient to operate, and all the procedures of charging and smelting should be operated by mechanical and automatic methods as much as possible;
⑥ the chemical stability and all aspects of the performance of the furnace brickwork ensure the quality of the melt.
The tonnage of the smelting furnace on the market is usually several tons to dozens of tons, but with the progress of society and the development of society, the smelting furnace with the tonnage can not meet the requirements of people, so that a smelting furnace with a large tonnage needs to be developed, and the smelting furnace with the large tonnage can also meet the basic requirements of the smelting furnace.
