Abstract

The embodiment of the invention discloses a high-temperature-resistant magnesia carbon brick high-performance antioxidant coating and a detection method thereof. The coating comprises the following raw materials in parts by weight: 20 parts of a sodium silicate solution, 0-35 parts of alumina, 0-50 parts of silica, 10-35 parts of silicon carbide, 0-20 parts of borosilicate glass, and 0-15 parts oftitanium dioxide. All the components are matched for use, so that the consumption of magnesia carbon bricks can be remarkably reduced; particularly, when the weight sum of alumina and titanium dioxide accounts for 0-50% of all the raw materials, the effect is particularly good, and in addition, the high-temperature-resistant magnesia carbon brick high-performance antioxidant coating has the advantages of being economical, effective, convenient to use and capable of being formed through one-time coating.

Description

technical field [0001] The invention relates to the field of materials, in particular to a high-performance anti-oxidation coating for high-temperature-resistant magnesia-carbon bricks and a detection method thereof. Background technique [0002] Magnesia carbon brick is a new type of refractory material that emerged in the 1970s. It is made of high melting point basic oxide magnesium oxide (melting point 2800 ° C) and high melting point carbon materials that are difficult to be infiltrated by slag. Non-oxide additives. A non-burning carbon composite refractory material combined with a carbonaceous binder. Magnesia carbon bricks are mainly used in the lining of converters, AC electric arc furnaces, DC electric arc furnaces, and slag lines of ladles. [0003] Magnesia-carbon bricks introduce graphite with high thermal conductivity, low expansion and non-wet to slag, which compensates for the shortcomings of poor spalling resistance of magnesia bricks, making it have the fol...
