Abstract
The present invention belongs to the field of refractory material technology, and is especially the recipe of one kind of material. The material has recipe comprising fire clay 20-90 wt%, boric acid 1-40 wt%, borax 5-40 wt%, urease 0.5-30 wt% and Epsom salt 0.5-30 wt%; and the material is ground to size of 180 mesh, stirred at normal temperature for 30-120 min and added water in 50-200 wt%.
Description
Graphite is because refractoriness can reach more than 3500 ℃, and acid and alkali alkali corrodes and is used in widely in the metallurgical refractory product again simultaneously.With charcoal bonded graphite and graphite-containing product, at high temperature unique shortcoming is a resistance to oxidation not, and for overcoming not sludge proof disadvantage of goods, various antioxidants are studied and developed in numerous producers in various degree to solve this needs.Add aluminium powder in the goods, silica flour can play certain anti-oxidative effect.How to make following carbonaceous article surface that contacts with air of high temperature not oxidated, and then prolong the duration of service of goods, reduce user's cost, increase the economic benefit of product, receive special concern.Before this, some producer is in the surperficial spray refractory coating of continuous casting with three-major-items, play certain beautifying and decorating effect, but the oxidizing reaction that can not stop oxygen and graphite, the result be to use in goods the continuous oxidation in top layer, constantly come off, reduced the work-ing life of goods greatly, invented this product for overcoming this disadvantage.Be characterized in,, can form the close solid porcelain protective layer of matter in the high temperature, stoped the oxidizing reaction of oxygen and graphite the surface of this antioxidant spray coating at graphite and graphite-containing product.And then can prolong the effective storage life of graphite and graphite-containing product, play the effect of synergy consumption reduction.
The invention belongs to a kind of antioxidant that is used for graphite and graphite-containing product, make by following component:
Refractory mortar 20-90%
Borax 5-40%
Epsom salts 0.5-30%
Boric acid 1-40%
Urea 0.5-30%
Whole granularities 〉=180 orders
Add water 50-200%
30-120 minute stirring at normal temperature time.
