A kind of preparation method of flexible electric arc furnace sealing insulation material

Abstract

The invention relates to a preparation method of a flexible electric arc furnace sealing and heat preservation material. The technical proposal includes the following steps: (1) adding 85-92% by weight silicon powder, 5-10% by weight zircon powder, and 3% by weight ‑5% soda ash is mixed evenly; (2) Add the powder into the aqueous solution of sodium polyacrylate with a mass fraction of 0.5%, and stir evenly, the weight ratio of the powder to the aqueous solution of sodium polyacrylate is 1:8‑10; soak the glass wool In the soaking liquid, after soaking for 20-30 minutes, take it out and dry it; the present invention not only has toughness but also strength, and can also prevent the heat loss of the electric arc furnace very well. , the material liquid in the furnace can be melted in advance, and the power consumption per ton of solution can be reduced by more than 200 degrees. The production of 25 tons of electric fused bricks per day can save power consumption by 5000 degrees, greatly reducing energy consumption, shortening the melting time, and directly increasing production capacity. More products can be produced at the same time.

Description

technical field [0001] The invention relates to a preparation method of a flexible electric arc furnace sealing and heat preservation material. Background technique [0002] The main material of masonry glass kiln is zirconium corundum electric fused brick. The production of electric fused brick is through the mixing of zircon sand, alumina powder and a small amount of soda ash to form a batch material, which is added to an electric arc furnace for high temperature melting at 2000 ℃ to become a material liquid. Then it is cast into the cavity of the sand mold, and after a period of heat preservation and annealing, it is the rough brick of the electric fused brick. In addition to raw material costs, labor costs, and equipment costs in the production process of electric fused bricks, there is another big consumption that is power consumption. The power consumption required to melt each ton of electric fused brick batch materials into a liquid can reach 2500°C to 3000°C , Very...

In addition to raw material costs, labor costs, and equipment costs in the production process of electric fused bricks, there is another big consumption that is power consumption. The power consumption required to melt each ton of electric fused brick batch materials into a liquid can reach 2500°C to 3000°C , very few manufacturers can achieve power consumption per ton of feed liquid at around 1700°C
