Description

Technical Field

[0001] The present invention relates to the field of steelmaking equipment, in particular to a repairing device for a lining of a smelting furnace. Background Art

[0002] During the smelting process, the furnace lining material is subject to varying degrees of corrosion at high temperatures. To extend its service life, the charge material must be repaired. The commonly used repair method is to use compressed air to spray powdered repair material through a pipe onto the repaired area; the material can be used after sintering. However, this method suffers from uneven mixing of the repair material and the inability to control the amount of material being added. This can easily lead to rebound of the repair material, preventing it from fully adhering to the repaired area.

[0003] In view of this, it is necessary to propose a smelting furnace lining repair device to solve or at least alleviate the above problems. Summary of the Invention
