Abstract
The invention discloses a mullite brick used for a dry quenching stove. The mullite brick used for the dry quenching stove is prepared of following raw materials according to the weight ratio: 25 to 35 parts of electric smelting mullite with a particle size of 5 to 3 millimeters, 25 to 35 parts of natural mullite with the particle size of 3 to 0 millimeters, 10 to 15 parts of corundum with the particle size of 250 to 300 millimeters, 3 to 6 parts of alumina powder with the particle size of 5 to 6 micrometers, 8 to 15 parts of andalusite concentrate with the particle size of 180 to 200 millimeters and 3 to 8 parts of clay binding agents with the particle size of 180 to 200 millimeters. The content of alumina of the mullite brick is more than 55%, the content of iron oxide is equal to or less than 1.3%, refractoriness is more than 1790 DEG C, the loading softening temperature is more than 1550 DEG C, density is more than 2.50 gram per cubic centimeter, gas hole ratio is less than 17%, and strength is more than 80 megapascal. Refractoriness is equal to or more than 1790 DEG C, the loading softening temperature is equal to or more than 1550 DEG C, gas hole ratio is equal to or less than 17%, volume density is equal to or more than 2.5 gram per cubic centimeter, compression strength is equal to more than 85 megapascal, breaking strength is equal to or more than 20 megapascal, abrasive resistance is equal to or less than 5 square centimeters, and thermal shock resistance (1100DEG C, water-cooling) is equal to or more than 30 times. The mullite brick used for the dry quenching stove can be well applied to positions such as a dry quenching cooling zone, a once dust remover, a pre-store area and the like.
Description
Technical field
The present invention relates to coking technology, be specifically related to a kind of for the mullite brick on coke dry quenching furnace.
Background technology
the general supporting mullite brick Main Function that uses on coke dry quenching furnace is the work-ing life of improving dry coke quenching, invest coke dry quenching furnace gross investment 2-3 hundred million Renminbi, because of go wrong cause the stopping production loss that causes of anti-material large, use common anti-material not reach the service requirements of coke dry quenching furnace, but this brick pore is high, compressive strength, the high temperature fold resistance is not high, thermal shock resistance is poor, wear resisting property is bad, the reasons such as the resistance to erosion corrosion-resistant property is poor, distortion in use easily appears, bonding, the problem such as come off, reduce work-ing life, increase production cost and finally cause blowing out, maintenance, overhaul.So this brick is substantially superseded.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of low pore, high volume density, high strength, high resistance folding, high-temperature behavior are good, high abrasion, corrosion-resistant property are good is used for mullite brick on coke dry quenching furnace.
Technical scheme of the present invention is: be used for the mullite brick on coke dry quenching furnace, it is made by the raw material of following parts by weight: granularity is the electrofused mullite 25-35 of 5-3mm, granularity is the natural mullite 25-35 of 3-0mm, and granularity is 250-300 purpose corundum 10-15, and granularity is the Al of 5-6 micron
2O
3Micro mist 3-6, granularity is 180-200 order andaluzite concentrate 8-15, granularity is 180-200 purpose clay wedding agent 3-8.
Describedly preferably made by the raw material of following parts by weight for the mullite brick on coke dry quenching furnace: granularity is the electrofused mullite 30 of 5-3mm, and granularity is the natural mullite 30 of 3-0mm, and granularity is 250-300 purpose corundum 12, and granularity is the Al of 5-6 micron
2O
3Micro mist 5, granularity are 180-200 order andaluzite concentrate 10, and granularity is 180-200 purpose clay wedding agent 5.
Raw material of the present invention is through mixed grind, high-pressure molding, sintering, and firing temperature is greater than 1450 ℃ of sintering.
The invention has the beneficial effects as follows: mullite brick Al
2O
3Content is more than 55%, Fe
2O
3Content≤1.3%; Refractoriness is greater than 1790 ℃, and loading softening begins temperature more than 1550 ℃, and density is greater than 2.50g/cm
3, void content is less than 17%, and intensity is greater than 80MPa.Refractoriness 〉=1790 ℃, refractoriness under load 〉=1550 ℃, void content≤17%, volume density 〉=2.5g/cm
3Compressive strength 〉=85 Mpa, folding strength 〉=20Mpa, wear resistance≤5 cm
2, thermal shock resistance (1100 ℃, water-cooled) 〉=30 times can well be applied to coke dry quenching furnace cooling section, disposable dust remover, the position such as the district that prestores.
Be mullite because dry coke quenching is supporting with the mullite brick essential substance, refractoriness, the volume stability of mullite brick have been increased, adding of corundum more improved volume density and wear resistance, adding of andaluzite concentrate, mullite brick transformation toughening and tiny crack have been improved toughness reinforcing, improved thermal shock resistance, avoided product in use because temperature fluctuation, recycle gas (N2) are carried the crackle that burnt grain and dust violent scour cause secretly, come off.Mullite brick uses can keep Stability Analysis of Structures on coke dry quenching furnace for a long time under high-temperature load, and embrittlement and ruckbildung do not occur, and high wear resistance and thermal shock resistance have improved serviceability and and the service efficiency of coke dry quenching furnace greatly.
