Pre-embedded electric heating flow channel

Abstract

The invention discloses a pre-embedded electric heating flow channel. An adopted flow channel body is a pre-embedded flow channel body and mainly comprises an iron casing, a plurality of connected liners, electric heating modules, heat preserving layers and cover plates, wherein inner cavities of the liners are used for allowing molten aluminum to flow by; the electric heating modules are arranged on two outer side surfaces of each liner; the iron casing wrapping the electric heating modules and bottom surfaces of the liners is arranged on the outer sides of the electric heating modules; the cover plates connected with the iron casing are arranged on top surfaces of the liners; the heat preserving layers are arranged between each electric heating module and the iron casing, between the bottom surface of each liner and the iron casing and between the top of each electric heating module and the corresponding cover plate. The flow channel is heated and subjected to heat preservation through the electric heating modules and the heat preserving structure, temperature reduction caused by the flow channel is compensated, the service life of the flow channel is prolonged, and the application range of a flow channel type degassing machine is broadened.

Description

technical field [0001] The invention relates to the technical field of molten aluminum processing equipment, in particular to a pre-embedded electric heating launder. Background technique [0002] In the aluminum processing and aluminum casting industry, the basic production process of the melting and casting workshop is as follows: the raw materials are put into the furnace to be melted into molten aluminum, then discharged, flow through various process equipment for processing, and finally flow into the casting equipment to form aluminum alloy products. The launder is the main channel for the transfer of molten aluminum between various process equipment. [0003] In the production process of the melting and casting workshop, in order to reduce the temperature drop of the molten aluminum caused by the launder and avoid the thermal shock causing the lining of the launder to crack, it is usually necessary to heat the launder. At present, the main operation method of heating ...

AI Technical Summary

Problems solved by technology

At present, the main operation method of heating the launder is to bake the lining of the launder by burning natural gas or charcoal. This heating method is inefficient and cumbersome to operate, and it cannot be carried out when there is aluminum liquid circulating in the launder.

With the complexity of aluminum processing and aluminum casting production processes, the total length of the launder used is getting longer and longer, and the temperature drop of the molten aluminum caused by the launder is getting higher and higher, which has directly affected the normal production in some applications.

[0004] The trough-type degassing equipment applied to the production line of the melting and casting workshop cannot solve the problem of temperature drop caused by the degassing process because it has no heating function, and its application range is limited
