    摘要: PURPOSE: A producing method of a magnesia based fire resistant product is provided to form an alumina based coating layer on the surface of the magnesia based fire resistant product using a thermal spray coating process for improving the corrosion resistance of the magnesia based fire resistant product by forming a spinel phase. CONSTITUTION: A producing method of a magnesia based fire resistant product comprises a step of forming an alumina based coating layer on the surface of the magnesia based fire resistant product using a thermal spray coating process. The thickness of the alumina based coating layer is thicker than 100 um. The thermal spray coating process is conducted by plasma thermal spraying at a temperature greater than 1,500°C. The producing method of the magnesia based fire resistant product additionally comprises a step of thermally processing the product at a temperature greater than 1,500°C after the formation of the alumina based coating layer. Magnesium oxide-aluminum oxide spinel is formed when the magnesia based fire resistant product with the alumina based coating layer contacts a high temperature object, by the reaction of alumina contained in the alumina based coating layer with a magnesia material.
