Abstract
A ceramic or glass cooker suitable for electromagnetic over is made up of raw ceramic or glass cooker through using an arc or flame thermospraying apparatus to smelt the Al or Al-alloy wire and spray the molten Al or Al-alloy onto the external surface of the bottom of said raw cooker. Its advantages are high adhesion, thermal efficiency and resistance to high-temp oxidation.
Description
Technical field
The invention belongs to electromagnetic oven dedicated ceramic and kitchen glassware applied technical field, be specifically related to be applicable to the pottery of electromagnetic oven and kitchen glassware and preparation method thereof.
Background technology
Pottery and kitchen glassware can not be placed directly on the electromagnetic oven and use, the advantage that pottery and kitchen glassware have many metal cooking appliances not compare.Prior art be adopt decal paper (with the raw-material decal paper of electromagnetic induction heating layer) or coating (containing the raw-material coating of electromagnetic induction heating layer) mode in kiln at pottery and the very thin electromagnetic induction heating layer of kitchen glassware bottom sintering one deck.Serious problem is that when above-mentioned pottery and kitchen glassware used on electromagnetic oven, cooker pot body may burst suddenly and can not continue to use, and has unsafe factor.Simultaneously, when above-mentioned pottery and kitchen glassware use on electromagnetic oven, the electromagnetic induction heating layer of its bottom is easy to generate the problem of high-temperature oxydation, and it will be lost efficacy whole electromagnetic induction heating layer by the part of high-temperature oxydation by the high temperature scaling loss in continuing the process of using.
The mode of production of above-mentioned decal paper is the present main mode of production.Pottery and kitchen glassware bottom after the mode of production of decal paper requires to burn till must be very smooth, certain camber can not be arranged, otherwise decal paper can not burn till thereon.And the pottery and the kitchen glassware of domestic production at present, particularly big slaughterhouse, glass pot and so on cooker, certain camber is arranged unavoidably at the bottom after it burns till, so be applicable to that the pottery of electromagnetic oven and kitchen glassware will have very big difficulty if adopt the mode of production of above-mentioned decal paper to produce in enormous quantities.
The production cost of the mode of production of above-mentioned decal paper or coating higher (cost that comprises decal paper or coating itself)
Summary of the invention
The object of the present invention is to provide a kind of pottery that is applicable to electromagnetic oven that can address the above problem and kitchen glassware and preparation method thereof, the problem that lost efficacy because of high-temperature oxydation can not take place in the electromagnetic induction heating layer of this cooker bottom, and the problem that cooker pot body in use bursts suddenly can not take place yet.The electromagnetic induction heating layer can be suitable for producing in enormous quantities attached to the cooker bottom that certain camber is arranged, and production cost is low.
The pottery that is applicable to electromagnetic oven provided by the invention and kitchen glassware and preparation method thereof, comprise electromagnetic induction heating layer of its cooker outer bottom and preparation method thereof, it is characterized in that: adopt electric-arc thermal spray coating equipment or flame wire rod thermal spraying apparatus with pure aluminum metal silk or aluminium alloy wire in high-velocity spray after the fusion under high-temperature electric arc or the thermal-flame to the ceramic material layer or glass material layer of above-mentioned cooker outer bottom, form pure aluminum metal material layer or the acieral material layer that is combined with it solidly thereon, to form the electromagnetic induction heating layer.
Contain fine aluminium more than 80% in the material component of above-mentioned acieral material layer, its alloying element comprises metallic elements such as magnesium, copper, nickel, chromium, manganese and rare earth, and acieral can be a bianry alloy, also can be multicomponent alloys such as ternary and quaternary.The bottom of above-mentioned pottery and kitchen glassware can be attached with the acieral material layer of above-mentioned different materials component, it can obtain different maximum electric power when working on same electromagnetic oven, with the above-mentioned pottery that satisfies different shaping and different heat resistances and the needs of kitchen glassware, satisfy user's different needs simultaneously.
The area of above-mentioned pure aluminum metal material layer or acieral material layer should be 100 millimeters the circle or the area of annular (50 millimeters of interior ring diameters) greater than diameter, and its thickness should be greater than 0.10 millimeter.
Require the bottom of above-mentioned cooker should be thinner, in order to heat-transfer effect.The bottom thickness of above-mentioned ceramic cooker is 2.0 to 5.0 millimeters, and the bottom thickness of above-mentioned kitchen glassware is 1.0 to 3.0 millimeters.
The outer surface of above-mentioned pure aluminum metal material layer or acieral material layer can be attached with fire resistant resin material protection layer, improves wear and corrosion behavior simultaneously in order to cleaning.
The high temperature insulation pottery after the material employing of above-mentioned pottery and kitchen glassware is burnt till and the material of high temperature insulation glass.
The cooker that common pure aluminum metal material or acieral material are made can not be responded to heating on electromagnetic oven, can not use.And adopt preparation method of the present invention on electromagnetic oven, can to generate heat by high-speed induction at the pure aluminum metal material layer or the acieral material layer of pottery and the preparation of kitchen glassware bottom, can use.In the cooker water should be arranged during use, can not dry combustion method.
Electromagnetic induction heating layer strong adhesion of the present invention, the impact of anti-rapid heat cycle and not coming off, wear and corrosion behavior is good, especially has the excellent properties of resistance to high temperature oxidation.Its surface will be if after being worn, the oxide-film of aluminium will form rapidly, have self-repair function.The oxide-film of aluminium has the excellent properties of resistance to high temperature oxidation.Intensification rapidly when the present invention worked, heat transfer is fast, the thermal efficiency is high, the problem that pot body bursts suddenly can not take place.Production cost of the present invention is low, is suitable for producing in enormous quantities.
