Abstract
The invention discloses a burner preformed part for a calcining kiln and a preparation method thereof. The preformed part is prepared from fused mullite, Si2Al4O4N4, Al3BC3, zirconium spinel, strontium carbonate powder, vanadium carbide powder, alumina micro-powder, high-alumina cement, composite powder, admixture and aluminum chloride solution. The preformed part is formed by adopting a self flowing pouring method, and is maintained, dried and heated at a high temperature. Compared with traditional castables, the preformed part has the characteristics of self flowing construction, self-defoaming, peeling resistance, high abrasion resistance, long service life and the like, and can be more widely applied to burner preformed parts of calcining kilns in various calcining kilns, such as flame-retardant industries, lime industries, roasting industries and metallurgic industries.
Description
Technical field
The present invention relates to a kind of calcining kiln burner prefabricated component and preparation method, particularly relate to refractory raw material calcining industry, cement industry, lime industry, ore deposit calcining industry, the calcining kiln burner prefabricated component that metallurgy industry is used and preparation method.
Background technology
Traditional burner is all that to adopt balk cargo to carry out vibrating casting at use scene shaping usually, thus extend the cycle stopping kiln, long construction period, field labor intensity are large, construction time add water many, curing cycle is grown, the finished product life-span is short, thus have impact on the normal production of rotary kiln.Simultaneously to be also difficult to meet antistripping in burner use procedure, life-span short for existing mould material product, the problems such as construction quality segregation is unstable.Prefabricated component refers to and changes supply of material pattern: burner completes cast, maintenance and thermal treatment at fire-resistant factory, then this product is moved to producer and directly uses, and the exploitation of this kind of product thoroughly solves the site operation weakness of traditional Unshaped Casting Refractories.
Summary of the invention
Object of the present invention is exactly to solve product not antistripping, heat-shock resistance is poor, the defect that life-span is short and construction quality is poor, a kind of calcining kiln burner prefabricated component and preparation method are provided, the preform product made can meet the antistripping that rotary kiln burner requires, the long lifetime, thermal shock resistance is high, easy construction, the problems such as steady quality.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: prefabricated component is by hercynite, Si

Described admixture is sulfonated melamine compound resin, isooctyl alcohol, 5-Sulfonic Salicylic Acid, and three's weight ratio is 2:1:1.Described liquor alumini chloridi density is 1.25 grams/cc, about PH3.5, viscosity 0.006KPa.s.
Above-mentioned each raw material is prepared burden in above ratio, after mixing, adopts the method for gravity flow pouring to be shaped, after maintenance, drying, at high temperature heat-treat, obtain this burner prefabricated component.
Preparation method of the present invention is:
Step one, batch mixing and stirring, prepare raw material by proportioning, adds admixture, stirs at stirrer, adds liquor alumini chloridi again after stirring, and controls 200 mm from flow valuve; Step 2, shaping, maintenance and drying, be shaped: installed by mould, add be stirred be uniformly mixed material, shakeout by the deadweight of compound and surface tension; 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 sclerosis, natural curing 48 hours again after the demoulding; Dry: the sample that maintenance is good carries out 110 DEG C of 24h drying and processings in electrical kiln, and powered-down treats its cool to room temperature; Step 3, thermal treatment, process furnace put into by dried sample, 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 rotary kiln prefabricated component.
The volume density of gained prefabricated component is at 2.7g/cm3, and strength at normal temperature 25MPa, is wear-resistingly less than 4, and work-ing life is more than 18 months.
The present invention obtains a kind of antistripping, the long lifetime, gravity flow construction, the calcining kiln burner prefabricated component of self-defoaming.This prefabricated component is high temperature resistant, antistripping, long lifetime, improve the operation factor of rotary kiln industry, gravity flow pouring during construction, pore can be eliminated voluntarily, avoids the quality segregation that vibrating casting material produces, change the shortcoming of original bulk products, the exploitation of this kind of product thoroughly solves the site operation weakness of traditional Unshaped Casting Refractories.
