摘要： PROBLEM TO BE SOLVED: To obtain a slag-compounded flame spraying material with basicity improved in serviceability. SOLUTION: This flame spraying material is obtained by including 5-40 wt.% of sintered calcia-magnesia clinker comprising 35-80 wt.% of CaO, 18-63 wt.% of MgO and 1.8-7 wt.% of Fe2 O3 with the content of CaO+MgO totaling >=93 wt.%, 30-70 wt.% of sintered magnesia clinker and/or fused magnesia, and 10-50 wt.% of slag. Because the sintered calcia-magnesia clinker moderately containing Fe2 O3 also contains 18-63 wt.% of MgO higher in melting point than CaO, formation of low-melting substances is suppressed despite being capable of improving the adhesivity of this material owing to the presence of Fe2 O3 , thereby securing the corrosion resistance of this material, resulting in improving the serviceability of this flame spraying material.

摘要： PROBLEM TO BE SOLVED: To enable the improvement of slaking resistance, and accordingly adherence and corrosion resistance of a magnesia-calcia clinker-based spraying material useful for repairing an industrial kiln or a container for molten metal. SOLUTION: Magnesia-calcia clinker is composed of 10-70wt.% of CaO and 30-85wt.% of MgO, where the total of CaO and MgO is >=95wt.%, and has an inorganic layer having slaking resistance on its surface. A magnesia-calcia clinker-based spraying material is produced by compounding 100wt.% of an aggregate consisting of a basic refractory raw material containing 5-90wt.% of the magnesia calcia clinker with 0.1-10wt.% of an ultrafine refractory powder having an average particle diameter of =10m /g, 0.1-5wt.% of slaked lime and a binder, each at outer percentage. The peering of the slaking-resistant inorganic layer existing on the surface of the magnesia-calcia clinker in spraying construction is prevented by virtue of the friction buffering effect attributable to synergetic effect of the ultrafine refractory powder and slaked lime, and accordingly adhesivity can be improved.

摘要： PROBLEM TO BE SOLVED: To obtain a flame spraying material with basicity bearing a combination of adhesivity and corrosion resistance. SOLUTION: This flame spraying material is obtained by compounding 10-50 wt.% of slag with 50-90 wt.% of fused magnesia containing 1-5 wt.% of SiO2 based on chemical analysis. The SiO2 incorporation in the fused magnesia dramatically improves the adhesivity of this material in a combination of the fused magnesia with the slag, thereby fully exhibiting the effect of corrosion resistance inherent in the fused magnesia, resulting in affording this material with excellent serviceability. Furthermore, although the fused magnesia is a dense stock, the above SiO2 incorporation suppresses the texture of an object to be applied from getting excessively dense, therefore this flame spraying material is also excellent in spalling resistance.

摘要： PURPOSE:To form spheroidized inorg. particles contg. less impurities and to stabilize a furnace operation for a long period of time by forming a thin layer stuck with spheroidized particles to the inside surface of the wall of the spheroidizing chamber of a vertical furnace having the spheroidizing chamber and cooling chamber and maintaining said layer. CONSTITUTION:An inorg. powder raw material, LPC and oxygen are injected from a thermal spraying burner A provided to a ceiling part 1 to the inside of the spheroidizing chamber B. The cooling chamber C is made into water cooled construction made of a metal to which water supply and discharge pipes 5, 5' are connected. The lower side of the chamber is reduced to a funnel shape and a cooling gas is blown from a cooling gas pipe 6 into said chamber. The spheroidized particles cooled in the cooling chamber C are sucked and transported by a blower from a transport system D and are subjected to a required treatment such as classification. The inside of the furnace wall 2 is always kept at the prescribed temp. selected from 600-1,100 deg.C by the forced cooling effect and the self-lining by the controlled spheroidized particles is formed.
