Embodiment 1

[0055] 90 parts of fused chromium corundum and 5 parts of chromium oxide are composed according to the particle size. According to the principle of first coarseness and then fineness, first dry blend in a wet mill. After the particles and fine powder are mixed evenly, add 90 parts of fused chromium corundum and 5 parts A mixture of white aleurone powder and water with a mass ratio of 7:3 is pressed at a pressure of 400T to form a brick, and the resulting brick is placed in a dryer and dried for 48 hours at a temperature of 200°C. Refractory material for furnace wall mouth of non-ferrous smelting furnace.

[0056] 67 parts of chromium corundum, 5.5 parts of capacitive chromium oxide, 4 parts of chromium oxide, 20 parts of high chromium ore, 8 parts of brown corundum powder and 6 parts of α-alumina micropowder are composed according to the particle size, according to the principle of first coarse and then fine, first in wet Dry mixing in the mill, after the granules and fine pow...

Embodiment 2

[0063] 92 parts of fused chromium corundum and 6 parts of chromium oxide are composed according to the particle size. According to the principle of first coarseness and then fineness, first dry mix in a wet mill, and after the particles and fine powder are mixed evenly, add 5 parts with a mass ratio of 4:5 The gel binder mixed with α-alumina micropowder and aluminum dihydrogen phosphate solution is pressed at a pressure of 480T to form a brick, and the resulting brick is placed in a dryer and dried for 48 hours at a temperature of 250°C to obtain a colored smelting Refractory materials for furnace wall mouth.

[0064] 60 parts of chromium corundum, 4 parts of capacitive chromium oxide, 3 parts of chromium oxide, 15 parts of high chromium ore, 5 parts of brown corundum powder and 4 parts of α-alumina micropowder are composed according to the particle size. Dry mixing in the mill, after the granules and fine powder are evenly mixed, add a mixture of white aleurone powder blendin...

Embodiment 3

[0071] 94 parts of fused chromium corundum and 7 parts of chromium oxide are composed according to the particle size. According to the principle of first coarseness and then fineness, first dry blend in a wet mill, and after the particles and fine powder are mixed evenly, add 5.5 parts. The mass ratio is 7:3 The mixture of white aleurone blended liquid and water is used as a binder, pressed at a pressure of 500T, and shaped into adobe. The adobe obtained is placed in a dryer and dried at a temperature of 240°C for 48h. A refractory material for the furnace wall opening of a non-ferrous smelting furnace is obtained.

Abstract

The invention relates to a high-strength fusion smelter for colored strengthening smelting. The smelter comprises a smelter wall port, an upper smelter wall, a smelter wall above a liquid line, a liquid line smelter wall, a smelter wall below the liquid line, a secondary working layer, a liquid outlet nozzle and a smelter bottom. All the parts of the smelter are made of fire-resistance materials,by analyzing working conditions of different parts of the high-strength fusion smelter for colored strengthening smelting, different kinds of fire-resistance material brasque are used as the corresponding parts, one or more properties of the erosion resistance, thermal shock resistance, washing resistance and permeability resistance of the brasque at the part are improved, the service life of thebrasque is greatly improved, frequent repairing and brasque replacement are avoided, and a large number of human resources and financial resources are saved.

Description

technical field [0001] The invention relates to the technical field of refractory materials, in particular to a high-strength melting furnace for non-ferrous intensified smelting. Background technique [0002] my country is a big producer of non-ferrous metals. With the rapid development of my country's transportation, energy, construction, electromechanical, communications, automobiles, household appliances, etc., and my country's neighboring countries such as Japan and South Korea with poor resources need to import a large amount of non-ferrous metals, various types Composite materials, alloys, ultra-thin copper plates, pipes and chemical products have a wide range of domestic and foreign markets, and the production capacity continues to expand, resulting in a series of problems such as: aging technology, outdated equipment, high energy consumption, high cost, serious environmental pollution, Problems such as shortage of mine resources and low recovery rate need to be resolv...
