Abstract

The invention relates to the technical field of metal smelting, in particular to an immersion type furnace heating system. According to the system, a heating unit is immersed to a heating object to heat directly so as to prevent oxidation, efficient heating can be achieved, a whole heating module is in a floating state and not prone to being damaged in an expansion and contraction process, and themaintenance is simple and convenient. A floating island is floated on metal liquid by utilizing the buoyancy of the metal liquid, the floating island is in a floating state and not prone to being damaged in the expansion and contraction process, and the maintenance is simple and convenient. Isolation walls are arranged on two sides of the floating island, the floating island can be effectively prevented from incline or turnover, high temperature resistance soft layers are arranged between the floating island and the isolation walls, an air heat insulation layer is arranged on the upper part of the floating island, so that the floating island and the metal liquid and high temperature located at the lower end can be blocked to transfer a great deal of heat to the upper part of the floatingisland, the atmosphere between the floating island and the metal liquid belongs to an anaerobic atmosphere, meanwhile protective air can be fed, a protective air layer is formed above the metal liquid, and the metal liquid is effectively prevented from oxidation.

Description

technical field [0001] The invention relates to the technical field of metal smelting, in particular to an immersion furnace heating system. Background technique [0002] In the field of metallurgy, melting metal is a very common and important process. The molten metal can be used to cast metal parts of various shapes. These include furnaces for heating high-temperature molten alloys for heat preservation and transfer processes. [0003] At present, there are two ways to heat the molten metal in the traditional furnace body: the first is an embedded heating furnace, the heating unit is embedded in the furnace wall at the bottom or side of the furnace, and the heating unit contacts the furnace wall and easily loses heat to the furnace body. In addition, due to the difference in expansion coefficient between the heating unit and the material of the furnace wall, the shrinkage of the two materials is inconsistent during shutdown and cooling, which may easily lead to damage to...
