Application Of Electric Furnace Bottom Ramming Material

Refractory Material

Application of Electric furnace bottom ramming material

The furnace age of the electric furnace is a restrictive link to improve the operation quality of the equipment and reduce the cost. According to the steelmaking plant's own situation, find the most suitable and economical furnace age, and rationally use the refractory materials in each part of the electric furnace, which can reduce the refractory materials to a certain extent. consumption, to achieve the purpose of saving energy and reducing consumption; at the same time, the increase in furnace age also prolongs the production time to a certain extent and improves labor efficiency. Angang No. ~80 times. Due to the asynchronous service life of the large furnace bottom brick and the furnace lining brick during use, the life of the electric furnace is low, and sometimes it is extremely difficult to repair due to the serious damage of the large furnace bottom brick. To solve this problem, in the electric furnace The promotion of the use of furnace bottom magnesia dry ramming material.

Classification

Using fused corundum and fused magnesia as the main raw materials and CaO as the sintering additive, the aluminum-magnesium dry ramming material was prepared by ramming. The amount of CaO added (mass fractions were 0, 0.5%, 1 %, 1.5%, 2%) on the phase composition, sintering performance and microstructure of Al-Mg dry ramming materials after heat treatment at 1 600 ℃ for 3 h. The results show that an appropriate amount of CaO can promote Al-Mg The sintering of dry ramming materials, the compressive strength at room temperature has been significantly improved
