According to a technical scheme in the invention, the porcelained powder comprises, by weight, 50 to 80 parts of ceramic powder, 5 to 10 parts of ball clay and 5 to 10 parts of quartz powder. The porcelained powder provided by the invention is capable of preventing severe deformation of the casting mold at high temperature, sand sticking of the mold and proneness to peeling, has good strength and can be widely applied to casting coatings.
Description
Technical field
The present invention relates to a kind of powder of cast paint, be specifically related to a kind of Vitrified powder and preparation method thereof.
Background technology
Carrying out all needing Cast-in-place hardfacing coating on mold core in the foundry technology processes such as EPC, V method, sand mold, ensureing the intensity of mold type, surface smoothness and casting dimension accuracy, preventing the generation of foundry goods scab defect, reaching the effect of easy to clean.
At present, most of producer is many in casting process adds high-temperature agglomerant to ensure casting effect in Cast-in-place hardfacing coating, but adhesion sintering could be carried out with aggregate when the operating temperature of high-temperature agglomerant generally needs to reach more than 1600 DEG C in actual application, but mold type is after building steel water, in mold type, temperature can only reach 1350-1650 DEG C, high-temperature agglomerant cannot play the effect of good adhesion sintering, coating aggregate adhesion sintering is not thorough, exist mainly with powder, do not possess elevated temperature strength, easily cause when pouring into a mould steel water, there is scab, the casting flaws such as infiltration and routed core.
Summary of the invention
The present invention overcomes the deficiency that prior art exists, and technical problem to be solved there is provided one and can prevent mold type high temperature to burst type, mold type scab and easily peeling off, Vitrified powder possessing good strength and preparation method thereof.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of Vitrified powder, by weight, is made up of following component,
Ceramic powder 50-80 part;
Ball clay 5-10 part;
Silica flour 5-10 part.
Preferably, also iron oxide red 0.1-0.2 part is contained in described component.
Preferably, in described ball clay impurity content lower than 3%.
Preferably, the crystal water content in described silica flour is less than 1%.
Preferably, described ball clay and silica flour replace to the hard paste grog of 10-15 part and a small amount of silica.
Preferably, described ball clay and silica flour replace to the zirconium English powder of 40-50 part and a small amount of silica.
Preferably, the zirconium content in described zirconium English powder is not less than 63%.
Present invention also offers a kind of preparation method of Vitrified powder, operate according to following steps,
A, get high aluminum ore and carry out high melt, smelting temperature is greater than 2300 DEG C, obtains melt liquid;
B, by melt liquid atomization cooling, obtain ceramic sand;
C, ceramic sand is carried out fragmentation, screening, obtaining granule size is 140-400 object ceramic powder;
D, to be mixed with ball clay, silica flour by 140-400 object ceramic powder, or mixed with hard paste grog, silica by ceramic powder, or mixed with zirconium English powder, silica by ceramic powder, mixing 15-90 minute, obtains Vitrified powder.
The main Vitrified powder adopting ceramic powders to prepare in the present invention, the effect of adhesion sintering good in casting process can be ensured, aggregate adhesion sintering reaches porcelain effect, and elevated temperature strength is high, and the casting flaws such as scab, infiltration and routed core do not appear in cast steel water.
In addition, Vitrified powder is added in cast paint, can ensure that phase transformation, sintering appear in each temperature range of coating, thus make dope layer reach the effect of overall porcelain, prevent steel water from permeating, cause penetration, add iron oxide red, can ensure that dope layer easily comes off, without the need to following process process.
