Magnesium aluminate spinel, Si in raw material2Al4O4N4、Al3BC3, zirconium spinel, strontium carbonate powder, be carbonized vanadium powder, and aluminum oxide is micro-
Powder, pure calcium aluminate cement, the parts by weight of composite powder are：Magnesium aluminate spinel 15-20 parts, Si2Al4O4N420-25 parts,
Al3BC37-12 parts, zirconium spinel 20-28 parts, strontium carbonate powder 1-3 parts, be carbonized vanadium powder 2-4 parts, alumina powder 8-12 parts, fine aluminium
Sour calcium cement 3-7 parts, composite powder 0-1 parts.Liquor alumini chloridi, the addition of additive account for the percentage of above-mentioned gross weight respectively
For：Liquor alumini chloridi 9%, additive 0.2-0.3%；Composite powder is made up of leucite powder and kaliophilite powder, and its weight is than 1:1.
Described additive is sulfonated melamine compound resin, and isooctanol, 5- Sulfonic Salicylic Acids, three's weight ratio is 2:
1:1.Described liquor alumini chloridi density is 1.25 grams/cc, pH3.5, viscosity 0.006KPas.
Above-mentioned each raw material is subjected to dispensing in above ratio, after being well mixed, shaped using the method for gravity flow pouring, through supporting
Shield, after drying, it is heat-treated at high temperature, obtains this burner prefabricated component.
The present invention preparation method be：
Step 1: batch mixing and stirring, prepare raw material by proportioning, add additive, stirred in mixer, stir
Liquor alumini chloridi is added after uniformly, 200 mm are controlled from flow valuve；Step 2: shaping, maintenance and dry, shaping：By mould
Tool installs, add be stirred be stirred material, the deadweight and surface tension by compound are shakeout；The material of excess surface is smeared
Go；Maintenance：The good sample of gravity flow pouring and mould are put into 25 DEG C of thermostatic chambers, are stripped after hardening on inspection, it is natural again after the demoulding
Maintenance 48 hours；Dry：The sample conserved carries out 110 DEG C of 24h drying and processings in electrical kiln, closes power supply and treats that it is cooled to room
Temperature；Step 3: heat treatment, dried sample are put into heating furnace, 300 DEG C are begun to warm to according to 5 DEG C/min, then with 10
DEG C/min speed is raised to 1000 DEG C, and is incubated 3 hours；After end, room temperature is naturally cooled to, this cement kiln is obtained after coming out of the stove
Use prefabricated component.
The bulk density of gained prefabricated component is in 2.7g/cm3, strength at normal temperature 25MPa, wear-resisting to be less than 4, service life exists
More than 18 months.
The present invention has obtained a kind of anti-strip, long-life, gravity flow construction, the cement kiln burner prefabricated component of self-defoaming.
The prefabricated component high temperature resistant, anti-strip, the long-life, improve the running rate of cement kiln industry, gravity flow pouring during construction, stomata can be with
Voluntarily eliminate, avoid caused by vibrating casting material quality and be segregated, the shortcomings that changing original bulk products, this kind of product is opened
Hair thoroughly solves the site operation weakness of traditional Unshaped Casting Refractories.
