Problems solved by technology

At the same time, the ladle slag line brick has the effect of preferential erosion on the edge during the erosion and erosion process, which will make the contact point of the ladle brick erode faster than the middle part of the single brick; and the ladle slag line brick is mainly magnesia carbon series, which has the potential to improve the life of the ladle Limited; if zirconia raw materials are directly used in ladle slag line bricks, the cost of raw materials will be greatly increased, and the purchase cost will be significantly increased for refractory plants and steel plants, which will reduce the profits of all parties

Abstract

The invention relates to the field of continuous casting function refractory materials and provides a ladle slag feather edge brick of a waste submersed nozzle slag line sludge material. The waste submersed nozzle slag line sludge material is mainly derived from a submersed nozzle used in a continuous casting workshop, a submersed nozzle slag line part mainly has the component of zirconium oxide,and the zirconium oxide used at the submersed nozzle is stabilized and has the advantages of being high in melting point, good in corrosion resistance, excellent in chemical stability, oxidation resistance and thermal shock stability, high in high temperature strength, very good in slag abrasion resistance, peeling resistance and molten steel impact resistance, and the like. Due to adoption of thewaste submersed nozzle slag line sludge material in the ladle slag feather edge brick, the slag abrasion resistance and the peeling resistance of the slag feather edge brick can be greatly improved,the service life of a ladle can be prolonged, the consumption of a ton steel refractory material can be reduced, pollution of the refectory material upon molten steel can be reduced, the wastes can beturned into wealth, the treatment expense of waste refractory materials can be reduced, and the environment pollution caused by the refectory materials and land occupation pressure can be reduced.

Description

technical field [0001] The invention relates to the field of continuous casting functional refractory materials, in particular to a ladle slag line brick made of waste submerged nozzle slag line material mud. Background technique [0002] With the strengthening of national environmental protection, the requirements for the mining of refractory raw materials are becoming more and more stringent, and some environmental supervision systems are gradually improved and implemented, which directly limits the supply of raw materials, making the cost of raw materials for refractory products production plants gradually increase, and severely compressed. company profits. At the same time, while consuming inventory, the reuse of waste materials is in line with my country's energy conservation and emission reduction, green development strategy and development requirements for reducing environmental pollution. The final treatment of the used waste submerged nozzles not only encroach on l...
