Abstract

The invention discloses an anhydrous carbonaceous hole plugging stemming material for a ferroalloy furnace and a preparation method of the anhydrous carbonaceous hole plugging stemming material. The anhydrous carbonaceous hole plugging stemming material comprises the following components: silicon nitride, silicon carbide, coke, asphalt, clay, an adhesive, a plasticizer, refractory adhesive mediumpowder, thermosetting phenolic aldehyde and an anhydrous carbonaceous adhesive. The preparation method comprises the following steps of: mixing the silicon nitride, silicon carbide, coke, asphalt, clay, refractory adhesive medium powder, thermosetting phenolic aldehyde and the anhydrous carbonaceous adhesive in proportion to form a mixture; uniformly stirring the mixture, adding the bulk materialinto a crusher, crushing and then drying the material; adding an adhesive agent and a plasticizer in proportion, performing stirring and detecting to obtain a product. The service cycle of the ferroalloy furnace can be greatly prolonged, and the service life of the ferroalloy furnace is prolonged. And meanwhile, long-time smooth operation of the condition of the furnace, and normal deslagging andcharring can be guaranteed, and the production index can be indirectly improved.

Description

technical field [0001] The invention relates to anhydrous carbonaceous hole-plugging clay for ferroalloy furnaces and a preparation method thereof. Background technique [0002] After the ferroalloy furnace is used for a long time, there will be holes due to corrosion or rust, commonly known as eyes or trachoma. Trachoma will greatly affect the performance of the ferroalloy furnace, so it needs to be repaired or blocked. [0003] At present, most domestic ferroalloy manufacturers have realized the importance of anhydrous taphole mud in the production process. The current anhydrous taphole mud technology is basically derived from the evolution and imitation of blast furnace anhydrous taphole mud. did not achieve the desired effect. It is generally believed that the key to anhydrous taphole clay lies in the control of the moisture content of the taphole clay, and other raw materials remain unchanged. Submerged arc furnaces are generally produced continuously for a long time,...
