Melting channel type cored induction zinc sheet casting furnace for zinc ingot production line

Abstract

The invention discloses a melting channel type cored induction zinc sheet casting furnace for a zinc ingot production line. The melting channel type cored induction zinc sheet casting furnace comprises a furnace body and a plurality of inductors arranged on the outer side of the furnace body, wherein the furnace body comprises a furnace shell and a furnace wall refractory material, and the furnaceshell is cuboid-shaped; the furnace wall refractory material is composed of a castable refractory layer, a high-alumina brick layer and a heat preservation brick layer which are sequentially arrangedfrom inside to outside, and the furnace wall refractory material is tightly attached to the inner surface of the furnace shell; the inductors comprise steel shells, iron cores, coils, bushings, melting channel passages and refractory materials, the iron cores, coils, the bushings, the melting channel passages and the refractory materials are arranged in the steel shells, and the coils are wound around the iron cores; and the refractory materials are arranged on the inner surfaces of the steel shells, the bushings are arranged between the refractory materials and the coils, and one ends of themelting channel passages communicate with the furnace body. According to the melting channel type cored induction zinc sheet casting furnace for the zinc ingot production line, the structure of the furnace body refractory material is reasonably optimized, the leakage resistance of the furnace body refractory material is improved, the temperature of the furnace shell is reduced, and the purposes of saving energy and reducing consumption are achieved.

Description

technical field [0001] The invention relates to a melting channel type cored induction zinc sheet melting and casting furnace used in a zinc ingot production line. Background technique [0002] As zinc ingot products are more and more widely used in various industries, especially the wide application of galvanized products, due to the excellent corrosion resistance of this product, this product has achieved great development in the fields of home appliances, automobiles and building materials. . [0003] The production of zinc ingot products has the following technical performance requirements and characteristics: a. The zinc melt is highly corrosive; b. The working temperature of the melt is high, 480°C; c. The freezing point of the zinc melt is very high. Due to large temperature fluctuations, Easy to solidify; d. Zinc melt is easily oxidized to form zinc slag at high temperature. [0004] Zinc flake melting and casting furnace is the key equipment in the zinc smelting i...
