Abstract

The invention discloses a kind of lime rotary kiln burner prefabricated component and preparation method, this lime rotary kiln burner prefabricated component is by fused mullite, Si2Al4O4N4、Al3BC3, zirconium spinel, strontium carbonate powder, carbonization vanadium powder, alumina powder, pure calcium aluminate cement, composite powder, additive and liquor alumini chloridi composition.The method using gravity flow pouring shapes, and through maintenance, after drying, at high temperature carries out heat treatment.Compared with tradition castable, this product has gravity flow construction, self-defoaming, anti-strip, the features such as wearability is high, life-span length, can be more widely used at the burner prefabricated component position of the rotary kiln used by various lime rotary kiln industries.

Description

One limekiln burner prefabricated component and preparation method
Technical field
The present invention relates to a kind of limekiln burner prefabricated component and preparation method, particularly relate to lime industry burner prefabricated component and preparation method.
Background technology
Traditional burner is the most all to use balk cargo to carry out vibrating casting molding at use scene, thus extend the cycle stopping kiln, long construction period, field labor intensity are big, construction time add water many, length curing cycle, final products life-span short, thus have impact on normally producing of limekiln.The problems such as the most existing castable product also is difficult to meet the anti-strip during burner uses, thermal shock resistance is poor, the life-span is short, construction quality segregation instability.Prefabricated component refers to change supply of material pattern: completing cast, maintenance and heat treatment at fire-resistant factory, then this product is moved to producer and directly use, the exploitation of this kind of product thoroughly solves the site operation weakness of tradition Unshaped Casting Refractories.
Summary of the invention
The purpose of the present invention is contemplated to solve product not anti-strip, thermal shock resistance is poor, the defect that life-span is short and construction quality is poor, one limekiln burner prefabricated component and preparation method are provided, the preform product made disclosure satisfy that the anti-strip that limekiln burner requires, long-life, and thermal shock resistance is high, easy construction, the problem such as steady quality.
For solving above-mentioned technical problem, the present invention adopts the following technical scheme that prefabricated component is by fused mullite, Si2Al4O4N4、Al3BC3, zirconium spinel, strontium carbonate powder, carbonization vanadium powder, alumina powder, pure calcium aluminate cement, composite powder, additive and water composition.
Fused mullite, Si in raw material2Al4O4N4、Al3BC3, zirconium spinel, strontium carbonate powder, carbonization vanadium powder, alumina powder, pure calcium aluminate cement, the parts by weight of composite powder are: fused mullite 15-20 part, Si2Al4O4N420-25 part, Al3BC37-12 part, zirconium spinel 20-28 part, strontium carbonate powder 1-3 part, carbonization vanadium powder 2-4 part, alumina powder 8-12 part, pure calcium aluminate cement 3-7 part, composite powder 0-1 part.Water, the addition of additive account for the percentage ratio of above-mentioned gross weight respectively: water 5-9%, and additive is 0.2-0.3%；Composite powder is made up of leucite powder and kaliophilite powder, its weight ratio 1:1.
Described additive is sulfonated melamine compound resin, isooctanol, 5-Sulfonic Salicylic Acid, and three's weight ratio is 2:1:1.
Above-mentioned each raw material is carried out dispensing in above ratio, after mix homogeneously, uses the method for gravity flow pouring to shape, through maintenance, after drying, at high temperature carry out heat treatment, obtain this burner prefabricated component.
The preparation method of the present invention is:
Step one, batch mixing and stirring, prepare raw material by proportioning, adds additive, stirs at blender, add water after stirring, control 200 mm from flow valuve；Step 2, shaping, maintenance and be dried, shape: installed by mould, add the stirring compound that is stirred, and deadweight and surface tension by compound are shakeout；The material of excess surface is erased；Maintenance: 25 DEG C of thermostatic chambers put into by the sample good by gravity flow pouring and mould, the on inspection demoulding after hardening, natural curing 48 hours again after the demoulding；It is dried: the sample that maintenance is good carries out 110 DEG C of 24h drying and processings in carbide ash furnace, closes power supply and treat that it is cooled to room temperature；Step 3, heat treatment, dried sample is put in heating furnace, begins to warm to 300 DEG C according to 5 DEG C/min, then is raised to 1000 DEG C with the speed of 10 DEG C/min, and is incubated 3 hours；After end, naturally cool to room temperature, after coming out of the stove, obtain this limekiln prefabricated component.
The bulk density of gained prefabricated component, at 2.7g/cm3, strength at normal temperature 25MPa, wear-resisting is less than 4, and service life is more than 18 months.
The present invention has obtained a kind of anti-strip, long-life, gravity flow construction, the limekiln of self-defoaming burner prefabricated component.This prefabricated component is high temperature resistant, anti-strip, long-life, improve the running rate of limekiln industry, gravity flow pouring during construction, pore can eliminate voluntarily, it is to avoid the quality segregation that vibrating casting material produces, the shortcoming changing original bulk products, the exploitation of this kind of product thoroughly solves the site operation weakness of tradition Unshaped Casting Refractories.
