Abstract
The invention belongs to the technical field of fireplace production, and particularly relates to an enamelling sheet steel fireplace and a manufacturing method thereof. A steel plate which is 4-6 mm thick is integrally machined into a fireplace body; the fireplace body is integrally annealed under 820-860 DEG C for 15-20 min; the annealed fireplace body is subjected to integral grinding and abrasive blasting; firstly, ground glaze slip is sprayed to the fireplace body obtained after grinding and abrasive blasting at the room temperature to 150 DEG C and then is dried, secondly, the fireplace body is sintered under 820-860 DEG C for 10-25 min and then cooled to 250-350 DEG C, thirdly, surface glaze slip is sprayed and then dried, and finally a finished product is obtained after the fireplace body is sintered under 760-860 DEG C for 10-25 min. The enamelling sheet steel fireplace integrates the features of the steel plate and the features of enamel glaze, and is a novel product in the original fireplace market; the defects that an original cast-iron enamelling fireplace is thick in wall and overlarge in wall thickness difference and consequently the overall weight is high and the appearance is bulky, and the like are overcome.
Description
Technical field
The invention belongs to fireplace production technical field, be specifically related to a kind of Enamelling Sheet Steel fireplace and preparation method thereof.
Background technology
The shell of the true fire burning type fireplace used both at home and abroad is at present except in order to also have except overall pitch-dark steel plate fireplace, cast iron is pitch-dark, cast iron enamel fireplace, and latter two is all adopt the split three after producing to assemble.The technical process that cast iron enamel fireplace is produced owing to adopting split, assembled later, often cause the product after assembling intuitively can feel each of fireplace each gap inequality after be combineding with each other, and former cast iron enamel fireplace wall thickness and difference is excessive easily causes the deficiencies such as overall weight is large, outward appearance is heavy.
Summary of the invention
For solving former cast iron enamel fireplace wall thickness and difference crosses the deficiencies such as roughly overall weight is large, outward appearance is heavy, the object of the present invention is to provide a kind of Enamelling Sheet Steel fireplace and preparation method thereof.
For achieving the above object, the technical scheme taked of the present invention is as follows:
The preparation method of Enamelling Sheet Steel fireplace, preparation process is:
(1), overall processing: 4-6mm Plate Steel is integrally processed into body of heater;
(2), integrally annealed: by body of heater at 820-860 DEG C of integrally annealed 15-20min;
(3), overall sandblasting: to the body of heater entirety polishing sandblasting after annealing;
(4), wet method heat spray: to the body of heater after polishing sandblasting, first spray ground-coat enamel slurry, with post-drying room temperature-150 DEG C, then, at 820-860 DEG C of sintering 10-25min, after being cooled to 250-350 DEG C, cover-coat enamel slurry is sprayed, dry again, then at 760-860 DEG C of sintering 10-25min, get product;
Wherein, the preparation process of described ground-coat enamel slurry is: (i) in weight percent summation 100%, batching: SiO

According to Enamelling Sheet Steel fireplace prepared by aforementioned preparation process.
Innovation of the present invention is:
1, differ for making steel plate fireplace and metallic object in preparation process because its moulding is impetuous, built-in, asymmetric and stress that is that produces obtains evenly reasonably discharging, fireplace of the present invention just adopts the integrally annealed of metal body of heater, it not only can get rid of its some stress completed in treating processes like this, metal surface is obtained fully oxidized, the impurity of the harmful enamel of part in steel plate can be got rid of again, later the overall sandblasting to body of heater is adopted, make steel plate spill brand-new metal surface, be convenient to the mortise of itself and enamel.
2, warding off some special cobalt nickel enamels by executing its top layer, making it in sintering process, produce enough physics and chemistry adherences with steel plate, both are combined as a whole securely.
3, adopt this novel method of wet method heat spray, the layer glaze that enamel coating top layer can be made to spray is controlled, and porcelain thickness is reasonably adjusted, can adjust the color and luster of layer glaze again (mainly through adjustment cover-coat enamel component proportions, such as MnO. simultaneously
2adjust intense violet color, Fe
2o
3adjust yellow), thus obtain the different porcelain thicknesses needed for design requirements, color and luster can adjust on request at any time.By wet method heat spray this method can by moisture content because the salt impurity in some pigments and other mill addition is reasonably disperseed, it can be obtained fully enough volatilizations in burning till again, avoid and burn till rear enamel coating and occur that salt mist film (spot) and strain line are not enough, thus make the outward appearance that the top layer of body of heater obtains.
Beneficial effect of the present invention:
1, be expert at the enamel fireplace that the overall application of slip of steel plate is produced in still belong to first batch of, it integrates the speciality of steel plate and frit for porcelain enamel, and the product of production is the another new variety on former fireplace market.
2, wet method hot spray method is adopted to carry out artificial glazing to body of heater top layer, the quality of product is made to obtain conservative control, the enamel coating quality at the particularly R angle place that some radius-of-curvature are less, the corner of metal body of heater can be made to be controlled, avoid enamel coating became uneven, uncontrollable adjustment, enamel gathering or the undesirable element such as deficiency at some specific positions, simultaneously by porcelain thickness and glaze adjusting performance, some performances such as enamel coating is heat-resisting, shock-resistant can be made to be improved.
3, adopt artificial method for making body of heater top layer can be made by the requirement of client the product (being realized by porcelain thickness and glaze adjusting performance) that different performance requires, make its top layer smoothly fine and smooth, glossiness is good, multiple color and luster, and color and luster is homogeneous, harmonious.
4, by the long burning method of low temperature after spraying, the stress deformation that whole body of heater causes because metal component structure is uneven can be avoided, can ensure that again enamel coating in use can bear local temperature difference and the deficiency such as crackle, burst porcelain caused.
5, the market of this product is expanded again by the adjustability of color, gloss further, and it can be the goods that each human consumer provides to achieve one's goal.
