Problems solved by technology

At high temperature, the metal reacts with oxygen to produce iron oxide scale, which significantly reduces the yield of steel, and severe oxidation will also cause surface quality problems on the surface of the billet after rolling, resulting in a serious waste of raw materials, energy and labor.
In order to solve the above problems, people spray anti-oxidation coatings on the metal surface, but the effect of these coatings is still not ideal at present, the oxidation burning rate is about 1.2%, and the yield is low

Abstract

The invention discloses a metal anti-oxidation coating. The metal anti-oxidation coating is mainly composed of the following components in percentage by weight: 3.68% of SiO2, 0.3% of Al2O3, 2.11% of CaO, 72.65% of MgO, 0.88% of Fe2O3 and 1.25% of Cr2O3. The coating provided by the invention has a certain inhibition effect on the oxidation of the steel billet at high temperature, the oxidation burning loss of the steel billet is reduced by 43.87%, and pressure oxygen defects are reduced by about 65.2%.

Description

technical field [0001] The invention belongs to the technical field of functional coatings, in particular to a metal anti-oxidation coating. Background technique [0002] Before rolling, the billet is generally heated in an oxidizing atmosphere heating furnace at a certain temperature (1250-1300°C) for 2-4 hours, or even longer. At high temperature, the metal reacts with oxygen to produce iron oxide scale, which significantly reduces the yield of steel, and severe oxidation will also cause surface quality problems on the surface of the billet after rolling, resulting in a serious waste of raw materials, energy and labor. In order to solve the above problems, people spray anti-oxidation coatings on the metal surface, but the effect of these coatings is still not ideal at present, the oxidation burning rate is about 1.2%, and the yield is low. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides an anti-oxidation ...
