Abstract
The invention discloses a kind of can be used for the silicon manganese steel is the enamel manufacturing process of blank.New ground-coat enamel and cover-coat enamel prescription have been adopted in the technology; The vertical flow coat of dipping or cast is warded off method; And adopt shredder that the porcelain facing after burning till is ground, burnt till again at last.The enamel product that adopts the present invention to produce has good resistance to acids and bases and wear resistance and higher precision, good adherence is arranged between enamel and the steel billet, but widespread use is the various industrial enamels of product with silicon manganese steel and soft steel.
Description
The present invention relates to the prescription of enamelled manufacturing process and enamel.
Existing enamel manufacturing process and enamel only are applicable to soft steel to be the enamel blank.But the intensity of these steel is relatively poor usually, and in many industrial products, the silicon manganese steel that the normal intensity of using is higher and the adhesion property of existing enamel are very poor.For the blank of tubulose or column, bad with existing dipping enamelling method application of slip effect, tend to occur the uppity phenomenon of uneven distribution or thickness, and when blank is heavier, also can't operate.And these products are generally to adherence, wear resistance, erosion resistance and having relatively high expectations of degree of making and precision slightly, so it is the qualified enamelware of blank that prior art can not be made with the silicon manganese steel.
Purpose of the present invention, be to adopt a kind of new enamel manufacturing process and enamel prescription, enamel is not only had with the soft steel blank also have the adherence good, and make the enamel product have well acidproof, alkali resistance, wear resistance and slightly degree of making and precision with the silicon manganese steel blank.
Specific embodiment of the present invention is:
The first, the silicon manganese steel blank of selecting for use is warded off pre-treatment.
Purpose by this process is the machining stress that will remove the greasy dirt on blank surface, zone of oxidation and elimination blank.
The second, the flow coat that hangs down is warded off method or the vertical flow coat of cast is warded off method application of slip ground-coat enamel slurry with flooding, and after the drying, burns till.
The flow coat method of warding off of hanging down dipping all immerses blank in the glaze slip exactly, with anchor clamps blank is vertically proposed, and treats till the glaze slip stop.This method is suitable for the blank of application of slip all styles of, and the outer wall of tubular blank especially should be wiped this part glaze slip off with rubber after the position seals of the application of slip or the application of slip not needing before the application of slip.
The vertical flow coat method of warding off of cast is the inwall that is used for application of slip tubular blank, make blank upright during the application of slip, a spheroid or a piston that has transmission rod is put into blank, mention to slight distance on blank with transmission rod, pour into a certain amount of glaze slip from above, allow spheroid or piston at the uniform velocity glide, glaze slip on the uniform cloth flow to till the stop glaze slip vertically downward in the blank.The elastic sphere that this kind method is adopted or the size of piston are should be in the internal diameter of blank consistent or be close.
The 3rd, ward off method or the cast flow coat that hangs down and ward off method application of slip cover-coat enamel slurry with the dipping flow coat that hangs down, drying, burn till after, repeat again a cover-coat enamel slurry the application of slip, dry, burn till.
Application of slip method in this process is identical with the application of slip method of ground-coat enamel slurry.
The 4th, after the longitude that porcelain facing is ground to drawing regulation with shredder requires, reburn into finished product.
Enamelware after burning till is because the enamel coating surface ratio is more coarse, variable thickness, thereby often do not reach desired precision, with shredder porcelain facing is ground to claimed accuracy after, burn till again, can meet the requirements of precision.
