Abstract
Description
Technical Field
[0001] This utility model relates to a heat-insulating casting furnace for producing copper alloys, and more particularly to a horizontal coreless heat-insulating casting furnace for producing copper alloy ingots. Background Technology
[0002] Copper processing enterprises primarily use induction furnaces to cast copper ingots, typically heated by a molten groove inductor. However, when producing high-end copper alloy ingots at high temperatures, the complex process and demanding high-precision ratios in the molten copper often result in problems. The molten groove inductor heating equipment suffers from insufficient stirring range, uneven mixing, and severe slagging in the high-temperature copper, frequently clogging the molten groove and causing equipment damage. In actual production, the quality of finished ingots is unstable, yield is low, equipment lifespan is significantly shortened, and production capacity is insufficient. These issues lead to high production costs, inconsistent product quality, limited scale, and an inability to generate stable and sustainable value. Therefore, this paper proposes a horizontal coreless insulated casting furnace for producing copper alloy ingots. Utility Model Content
[0003] The purpose of this invention is to overcome the problems of uneven material mixing and severe slagging in the high-temperature molten copper during the production of high-end alloy ingots. These problems lead to blockage of the melting channels in the equipment, reducing its service life, and resulting in unstable ingot quality and a low pass rate for finished products, affecting mass production and quality. Through a reasonable design, this invention provides a horizontal coreless insulated casting furnace for producing copper alloy ingots. The furnace structure employs a horizontal furnace body and a lower furnace body. Small-scale material feeding is performed in the horizontal furnace body through observation windows and cover plates. The high-temperature molten copper for high-end copper alloys has a large mixing range and uniform material mixing, reducing slagging. The high-temperature molten copper for high-end copper alloys is kept in an insulated and relatively sealed condition for adjusting the component ratio. The casting pipe can be sealed and kept insulated during casting, avoiding the problem of melting channel blockage in existing equipment.
