Metal block smelting furnace equipment for secondary heat recycling

Abstract

The invention discloses metal block smelting furnace equipment for heat secondary cyclic utilization. The metal block smelting furnace equipment comprises a smelting crucible body, the smelting crucible body is sleeved with a heat insulation and preservation sleeve, and the circumferential side wall of the heat insulation and preservation sleeve is wound by an electromagnetic induction heating coil. A flue gas conveying pipeline is made communicated with the bottom side wall of a gas heating chamber. An air circulation pipe is arranged between the pipe body right side wall of an outer cavity air guide-in pipe and the pipe body left side wall of a hot air guide-out pipe in a communicated mode. A deslagging agent storage tank is fixedly installed below a supporting installation frame. The body of a rotary stirring rotating shaft is evenly provided with a plurality of stirring blades. The body of a deslagging agent discharge pipe is provided with a manual switch valve. By means of the metal block smelting furnace equipment, the problem that resources are seriously wasted when a large amount of heat doped in flue gas is directly discharged out of a furnace is well avoided, workers will not be scalded in the delivery process, deslagging agent placement is more convenient and faster, and a deslagging effect is ensured.

Description

technical field [0001] The invention relates to the related technical field of metallurgical processing equipment, in particular to metal block smelting furnace equipment for secondary heat recycling. Background technique [0002] In the modern metallurgical industry, it is necessary to smelt and process metals. Smelting is to put metal materials and other auxiliary materials into a heating furnace to melt and temper them. The materials in the furnace at high temperature (1300-1600K) undergo certain physical and chemical changes. A pyrometallurgical process that produces crude metal or metal concentrates and slag; in addition to concentrate, calcined sand, sintered ore, etc., sometimes it is necessary to add a flux to make the charge easy to melt, and to add a certain reaction Reductant; In addition, in order to provide the necessary temperature, it is often necessary to add fuel to burn and send in air or oxygen-enriched air. Crude metal or metal enrichment can be separate...

Problems solved by technology

[0003] Melting furnace equipment is needed for smelting, but in the past, during the long-term processing of the melting furnace, a large amount of smoke will be generated in the inner cavity. The traditional method is to directly discharge the smoke. In fact, the smoke is still Doped with a lot of heat, the heat has not been fully utilized and this kind of resource is seriously wasted, the heat utilization rate is seriously reduced, and the use effect is very poor. The slag removal agent is sent in by the way of the trolley, which will not only directly lead to the appearance of unevenness in the delivery process, but also cause scalding accidents due to high temperature, which may cause workers to operate incorrectly, and the effect of removing impurities is not good, affecting The quality of the finished product after the entire metal is melted needs to be solved
