Cast iron type water-cooling furnace cover of refining furnace

Abstract

The invention relates to a cast iron type water-cooling furnace cover of a refining furnace, which adopts a casting instead of a welding part. More than one water-cooling pipe is embedded into the furnace cover, and each water-cooling pipe is provided with a water inlet and a water outlet. A plurality of mud hanging gears are embedded on the working surface of the furnace cover. The mud hanging gears are in a shape like the Chinese character da, i.e. the hanging parts are embedded into the working surface of the furnace cover, and the hung gear parts are exposed outside the working surface ofthe furnace cover. The cast iron type water-cooling furnace cover of the refining furnace can be divided into an integral type or a split type according to the structure of the furnace cover, and thesplit type furnace covers are spliced together for use. Steel pipes in various forms are embedded into the furnace cover according to the structures of different furnace covers, a certain number of mud hanging gears are embedded on the working surface of the furnace cover, and refractory materials with certain thickness are sintered at the mud hanging gear parts or a certain number of refractory bricks are embedded on the working surface. The cast iron type water-cooling furnace cover can be adapted to the complicated and severe working conditions of the refining furnace and has the advantagesof no water leakage and cracking, difficult deformation and slag adhesion, long service life, and the like.

Description

technical field [0001] The invention relates to a refining furnace in the metallurgical industry, in particular to a cast iron type water-cooled furnace cover for the refining furnace. Background technique [0002] The furnace cover of the refining furnace is one of the important spare parts of the refining furnace. The working conditions of the refining furnace are complicated and the conditions are harsh. During the refining process, the furnace cover is prone to problems such as water leakage and slag sticking, which will affect the normal operation of the refining furnace. The furnace cover is a consumable spare part of the refining furnace, and the consumption is relatively large. [0003] At present, domestic and foreign refining furnace covers are divided into water-cooled parts and non-water-cooled parts, all of which are welded parts of steel structure. The use of welded water-cooled furnace cover can eliminate the phenomenon of slag sticking to a certain extent, ...

AI Technical Summary

Problems solved by technology

The use of welded water-cooled furnace cover can eliminate the phenomenon of slag sticking to a certain extent, but it will reduce the refining temperature, and it is prone to water leakage, which will affect the refining process

The non-water-cooled furnace cover is to set a certain thickness of refractory material or insert a certain thickness of refractory bricks at the bottom of the furnace cover. This method can ensure the normal operation of the refining furnace, but the slag is serious, and the slag removal work needs to be carried out frequently, thus affecting the refining. Productivity
