Heating pipe and installation method thereof

Abstract

The invention discloses a heating pipe which comprises a protection pipe, a heating element and a fireproof supporting block on the inner bottom surface of the protection pipe, wherein the fireproof supporting block is arranged between the heating element and the protection pipe. According to the invention, by adding the fireproof supporting block inside the protection pipe of the heating pipe to isolate the heating element from the pipe wall of the protection pipe, the heating element is prevented from being in direct contact with the pipe wall of the protection pipe and the condition of local overheating cannot occur to the pipe wall, which is very sensitive to temperature variation, of the protection pipe, so that the service life of the pipe wall of the protection pipe is prolonged, the consumable quantity of the protection pipe is reduced and economy of the integral device is promoted. In addition, the invention also provides a heating pipe installation method. The method can avoid damage to the heating pipe and prolong the service life of the heating pipe.

Description

technical field [0001] The invention relates to the field of metal processing, in particular to a heating pipe and an installation method thereof. Background technique [0002] In recent years, with the rapid development of the chemical industry and manufacturing industry, China's aluminum industry has entered the stage of the world's largest producer of aluminum industry. The manufacture of aluminum products has also been continuously improved with the improvement of manufacturing production requirements, and the purification requirements for aluminum products have also increased. [0003] In the metal smelting process, especially in the manufacturing process of aluminum products, the degassing chamber heating system is one of the commonly used equipment. The aluminum alloy melt flows from the degassing chamber to the casting machine to achieve the purpose of purifying the aluminum alloy liquid. [0004] The degassing chamber heating system is to provide enough heat to th...

AI Technical Summary

Problems solved by technology

The disadvantage of this technology is that the wall of the protective tube is relatively thin, usually only about 10 mm, and the material of the tube wall is very sensitive to temperature. When it contacts a high-temperature heating element, it may cause high local heating and damage the tube wall

In addition, the heating tube is placed in the aluminum liquid during use. Due to the influence of buoyancy, the heating tube floats up and down and swings left and right, which increases the possibility of damage to the heating tube.

[0007] Therefore, the service life of the existing heating tube is short, which not only wastes materials, but also wastes the time for replacing the heating tube, which has a negative impact on the process of manufacturing aluminum products
