Embodiment 1

[0083] Hereinafter, the effects of the present invention will be specifically described with reference to examples of the present invention and comparative examples deviating from the scope of the present invention.

[0084] First, as an example of the present invention, hot rolling, cold rolling, annealing, and 1.0% conditioning were performed on continuously cast steel ingots with various chemical compositions shown in Table 1-1 and Table 1-2 under various manufacturing conditions. Quality rolling to produce a steel plate with a thickness of 0.8mm. At this time, an oxide film is also formed on the surface of the steel sheet. Next, glazing was applied to this steel plate, and the characteristics of enamel were investigated. In glazing, a 100 μm glaze agent for the top glaze layer is dry-coated by a powder electrostatic coating method. Underglaze coating is not performed.

Abstract

An enameling work capable of securing adhesion, blister / black speck resistance and fishscale resistance even when pretreatment or ground coating is omitted, which work is a steel sheet which contains by mass C: 0.0001 to 0.040%, Si: 0.0001 to 0.50%, Mn: 0.001 to 2.00%, P: 0.0001 to 0.10%, S: 0.0001 to 0.060%, Al: 0.0001 to 0.10%, N: 0.0001 to 0.015%, O: 0.0001 to 0.070%, and at least one selected from among Ni: 0.01 to 2.00%, Co: 0.0005 to 2.00%, Cr: 0.001 to 2.00%, Cu: 0.01 to 2.00%, Mo: 0.0001 to 2.00%, and Ti: 0.0005 to 0.50% with Ni+Co+Cr / 2+Cu+Mo+Ti: 0.010 to 8.0% and with the balance consisting of Fe and unavoidable impurities and whichhas on the surface a 0.1 to 400-[mu]m thick oxide layer consisting of the oxides of the components constituting the sheet; and enameled products.

Description

technical field [0001] The present invention provides processed products for enamel glazing, processed products for enamel glazing, and methods for producing them at low cost and excellent in enamel properties (bubble and black spot resistance, adhesion, fish scaling resistance (fishscaling)) and processing properties. Background technique [0002] Enamel processed products are products formed by forming a vitreous enamel layer on the surface of a metal substrate composed of steel, cast iron, aluminum, copper, and stainless steel. The glaze (glass frit) is then fired at high temperature to make it. The surface of the enamel processed product is not easy to produce defects, and can easily remove oil stains, etc., and is excellent in heat resistance, acid resistance and alkali resistance, so it is used in kitchen products, tableware, sanitary containers, and interior and exterior decoration materials of buildings, etc. Has a wide range of uses. [0003] Usually, when enamel ...
