Abstract
The invention discloses a high purity andalusite brick and a preparation method thereof. The ingredients of the high purity andalusite brick adopt andalusite, additives and binding clay as raw materials. The preparation method is as follows: firstly, the raw material of the andalusite is iron removed by magnetic separation by conventional method; then 200 orders of the andalusite, the binding clay and the additives are mixed to be ground; after the mixture is fully ground evenly, the mixture is prepared into powder; the andalusite, whose grain sizes are 3 to 1 mm and 1 to 0 mm, is introduced into a wet grinder to be mulled together with a binder; then the prepared powder is added to be mulled, aged and mulled again with the andalusite, and the powder and the andalusite are prepared into pug; the prepared pug is pressed by machine into green bricks; and the green bricks are introduced into a high temperature tunnel kiln to be fired, and the product is obtained. When the product of the high purity andalusite brick is used as the refractory of the large hot blast stove, the creep rate is low and the thermal shock resistance is good, so the product can obviously improve the blast temperature and the service life of the hot blast stove. Thus, the product saves plenty of maintenance expenses and energy saving expenses for the steel users, and has achieved remarkable social benefits and economic benefits.
Description
One, technical field:
The present invention relates to the used refractory materials of a kind of large-scale hotblast stove, particularly relate to used high-purity andalusite brick of a kind of large-scale hotblast stove and preparation method thereof.
Two, background technology:
Along with the fast development of Chinese national economy, increasing to the demand of ferrous materials, in order to meet the needs of production, the iron and steel output of China is fast rise trend year by year.By 2006, China's iron and steel output reached 400,000,000 3 thousand ten thousand tons.In the last few years, iron and steel output increase the large scale development of mainly giving the credit to blast furnace rapidly, promoted the most important attached Thermal Equipment of blast furnace---developing rapidly of hotblast stove in the time of the blast furnace development, hotblast stove realizes that to blast furnace high yield, low consumption and reduction pig iron cost play important effect as a kind of heat exchanger of heat accumulating type.
In recent decades, hotblast stove progressively develops to high wind-warm syndrome, maximization and long-life direction, brings up to 1100～1200 ℃ as the wind-warm syndrome of hotblast stove by early stage 900 ℃, and in some developed countries, the wind-warm syndrome of hotblast stove has reached 1200～1300 ℃.Modern hotblast stove requires to realize that 25～30 years furnace lining masonries do not have the target of maintenance, to the strict demand of hotblast stove each side, makes that the environment for use of the used refractory materials of hotblast stove is more and more harsher.Present used refractory materials is that the restriction hotblast stove is realized high wind-warm syndrome operation and long-life key factor.
At present, the damage reason of domestic large-scale hotblast stove mainly contains: 1, the high temperature creep rate height of used refractory materials; 2, the thermal shocking effect of high wind-warm syndrome; 3, the erosion action of flue gas; The structure deteriorate that the expansion of 4 brick masonarys causes etc.
The principal mode of the used refractory materials of present domestic hotblast stove has: a) silica brick-high alumina brick-clay brick; B) Low Creep High Alumina Bricks (mullite brick)-high alumina brick-clay brick; C) silica brick-low creep brick-high alumina brick-clay brick.No matter adopt which kind of form, the material of its high temperature position is the key of hotblast stove selection.Integrating is exactly the material of the crucial material of two classes: silica brick and low creep brick.When hot blast temperature during, generally select for use high alumina brick, mullite brick and silica brick to make furnace lining or checker brick at 1100～1200 ℃; When hot blast temperature was higher than 1200 ℃, high alumina brick can not meet the demands, and silica brick need be used in hot blast furnace roof and partition wall and regenerator top, used low creep brick in silica brick layer bottom.And the external used refractory materials of hotblast stove is also paid attention to especially to creep resistance except performances such as volume density, heat-shock resistance and intensity being had strict requirement, at general silica brick, mullite brick and the andalusite bricks of using of high temperature position more.
At present, the used refractory materials of hotblast stove is to be developed by the direction of high alumina brick to mullite brick, high-quality silica brick, sillimanite brick and andalusite brick generally.Wherein the Apyre flame-proof material has obtained applying preferably on hotblast stove, but domestic and international most of producer mostly is and adds a small amount of andaluzite in starting material at present, with the alumine is main raw material, makes the degradation of goods can't satisfy the long-life requirement of hotblast stove.Therefore, for the processing temperature that makes China modernization hotblast stove with reach requirements at the higher level work-ing life simultaneously, the used refractory materials of a kind of fine hotblast stove of development research is very important.
Three, content of the present invention:
The objective of the invention is: overcome the problem that the used refractory materials of present maximization hotblast stove exists, provide a kind of and can satisfy hotblast stove high-temperature service and the high-purity andalusite brick of long-life high-quality and preparation method thereof.
