Aluminum ingot melting furnace

Abstract

The invention relates to the technical field of smelting furnaces, in particular to an aluminum ingot smelting furnace. The aluminum ingot smelting furnace comprises a smelting furnace body, a discharging opening is formed in the outer surface of the front end of the smelting furnace body, a lifting groove is formed in the annular outer surface of the rear end of the smelting furnace body, a lifting block is movably connected into the lifting groove, and a heat preservation cover is hinged to the outer surface of the upper end of the lifting block; sliding grooves are formed in the symmetrical positions of the annular outer surface of the heat preservation cover, and sliding blocks are slidably connected into the sliding grooves; lifting covers are fixedly connected to the outer surfaces of the sides, away from the sliding grooves, of the sliding blocks; the heat preservation cover body is composed of a plurality of heat preservation covers, and in every two adjacent heat preservation covers, the heat preservation cover on the inner side is provided with an inner groove, and the upper end of the heat preservation cover on the outer side is fixedly connected to a positioning block; and a spring is arranged between the positioning block and the inner groove for supporting, the innermost layer of heat preservation cover of the heat preservation cover body is made of transparent quartz glass, the other layers are made of steel materials with the bottom ends coated with high-temperature-resistant pattern layers, and the heat preservation range can be enlarged through a series of structures.

Description

technical field [0001] The invention relates to the technical field of melting furnaces, in particular to an aluminum ingot melting furnace. Background technique [0002] Aluminum ingot melting furnace is an equipment mainly used for melting and heat preservation of aluminum ingots in the aluminum ingot casting process. The ingot melting furnace melts solid aluminum originals into liquid at high temperature, and then forms an automatic production line of aluminum products with subsequent die-casting, forming and other processes. Quickly and efficiently pouring liquid aluminum water to the subsequent process is one of the factors affecting the efficiency of the automatic production line of aluminum products. How to heat quickly and evenly is one of the important factors to ensure the quality of aluminum ingot melting. [0003] In the process of realizing the present invention, the inventor found that at least the following problems in the prior art have not been solved: the t...
