Problems solved by technology

This maintenance process takes a long time, the period is long, and the construction is cumbersome. During this period, the use of the submerged arc furnace must be stopped, which affects the normal production of the submerged arc furnace, and the economic loss before the resumption of production is large.
That is to say, if this happens, the furnace must be shut down for a long time for maintenance to replace the damaged furnace lining, and the long-term shutdown affects the economic benefits of smelting

Abstract

The invention belongs to the technical field of smelting furnace equipment and facilities, and discloses a furnace lining module, which includes an anchor and a furnace lining material. The main body of the anchor is a hollow heat-resistant tube. The lining material is fully bonded to form a block, and the ends of the anchors are flush with the surface of the lining material. Also disclosed is a method for repairing the damaged lining of a fully enclosed submerged arc furnace, which includes four steps: 1. Prefabricate the furnace lining module; 2. Clean up the damaged part of the furnace lining; 3. Install the furnace lining module; The hollow part of the heat pipe and the gap between the damaged part of the furnace lining around the furnace lining module form an integral seal. The furnace lining module of the present invention can be prefabricated in advance by using readily available materials, and the furnace lining module can be used to repair the damaged part of the furnace lining without removing the furnace cover, thereby improving efficiency and reducing maintenance time and impact on production.

Description

technical field [0001] The invention belongs to the technical field of smelting furnace equipment and facilities, and in particular relates to a furnace lining module and a method for repairing damage to a fully enclosed submerged arc furnace lining. Background technique [0002] In mineral smelting, the smelting furnace is a common equipment for mineral smelting. Among them is a fully enclosed submerged arc furnace. The furnace body has a furnace cover and a furnace lining. The furnace lining is used to seal the gap between the furnace body and the furnace cover. , The furnace cover and the furnace lining form a sealed whole, and the furnace cover bears the role of sealing the high-temperature flue gas generated during the smelting process. [0003] The high temperature of smelting inside the furnace body will be transmitted to the furnace cover and furnace lining, and the high-temperature flue gas generated during smelting is often corrosive, so that the furnace lining is ...
