Abstract
The invention discloses a kind of preparation method of compound zirconia HTHP atomizer, comprise the following steps that：（1）Zirconium silicate, magnesia, calcium oxide and oil glue are put into mixer, mixed, then prepare melting charge；（2）Basic zirconium chloride, calcium chloride and magnesium chloride are put into reactor, saturation ammoniacal liquor is added and carries out coprecipitation reaction；（3）By melting charge and particulate material mixing and ball milling, dispersant, plasticizer and defoamer, mist projection granulating are added；（4）By step（3）Isostatic pressing, is made nozzle green compact；（5）High-temperature calcination is carried out to nozzle green compact；（6）Nozzle blank is ground to by size finished product compound zirconia nozzle up to standard using diamond abrasive tool.The technique that the present invention is combined using chemical method and electric smelting method powder, so that material crystalline is complete, there is good sintering character again simultaneously, densification degree is fine, therefore gained sintered body has good high-temperature behavior, high temperature abrasion resistance, anti-corrosion property at high temperature concurrently simultaneously.
Description
Technical field
The invention belongs to the preparing technical field of electrostatic atomization apparatus, and in particular to a kind of compound zirconia HTHP mist
Change the preparation method of nozzle.
Background technology
HTHP atomizer is the crucial fire resisting erosion resistance part for entering to be about to alloy melt high-pressure atomization, main
Be used for cemented carbide industry, high-quality Powder Metallurgy Industry, due to these use occasion operating mode very severes, erosion, abrasion,
High temperature, violent thermal shock, general refractory part are difficult to bear this operating mode, therefore zirconium oxide HTHP atomizer turns into pass
Key key element.At present, domestic preferably zirconium oxide HTHP atomizer is mainly regular oxidation zirconium refractory product, and mostly according to
Rely import, and the service life of compound zirconia HTHP atomizer improves 1-2 times compared with imported material, has filled up domestic skill
Art blank.
The content of the invention
The purpose of the present invention, which is that, overcomes existing technical deficiency high there is provided a kind of compound zirconia of service life length
The preparation method of warm high pressure atomizing nozzle.
The purpose of the present invention is realized in the following manner：
A kind of preparation method of compound zirconia HTHP atomizer, is comprised the following steps that：
（1）Zirconium silicate, magnesia, calcium oxide and oil glue are put into mixer, mixes 2-3 hours, mixed material is put
Melting charge is prepared in electric smelting in electric arc furnaces, and electric smelting temperature is 2600-3000 DEG C, time 100-180min, then melting charge is used
Raymond mill is milled to 1.5 microns of median；
（2）Basic zirconium chloride, calcium chloride and magnesium chloride are put into reactor, saturation ammoniacal liquor is added and carries out coprecipitation reaction, gained
Precipitation colloid calcines the particulate material for preparing chemical method by 800-1100 DEG C；
（3）By step（1）Melting charge and step after obtained mill（2）Obtained particulate material is by 8:2-9:1 ratio mixing, plus
Enter in ball mill, wet ball grinding to average grain diameter be less than 0.6 μm, add 0.5-1wt% dispersant and 2-4wt% plasticizer and
0.5-1wt% defoamer, is made mobility and the good slurry of plasticity and mist projection granulating, is made available for isostatic pressed
Pelletizing；
（4）By step（3）Nozzle is made in gained pelletizing isostatic pressing under 100-180Mpa, Digit Control Machine Tool green machined
Green compact；
（5）High-temperature calcination is carried out to nozzle green compact, described sintering curve is：- 600 DEG C of room temperature, uniform heating in 12-18 hours is de-
Fat；600-1350 DEG C, 9-12 hours uniform heating crystal-phase transformations；1350-1725 DEG C, 12-18 hours uniform heating sintering, 1725
DEG C insulation 6-10 hour insulation crystal grain handle；1725- room temperatures, 50 hours cold true, and this process is uniform decrease in temperature, no insulation；
（6）Nozzle blank is ground to by size finished product compound zirconia nozzle up to standard using diamond abrasive tool.
The zirconium silicate is 86-97 parts, magnesia is 2-7 parts, calcium oxide is 1.3-7 parts, petroleum coke is 6-11 parts.
The basic zirconium chloride is 65-89 parts, calcium chloride is 8-25 parts, magnesium chloride is 2.5-13 parts.
The step（2）The addition of middle saturation ammoniacal liquor is the 3-15% of solid masses in reactor.
The step（3）In dispersant be dispersant 9400, plasticizer be plasticizer 1788, defoamer be tricresyl phosphate fourth
Ester.
