摘要： PURPOSE:To improve product yield and to provide prolonged heat resistance and thermal shock resistance by blending 2MgO.SiO2 and MgO.4ZrO2 in a specific ratio. CONSTITUTION:A thermal spraying material is composed of a 2MgO.SiO2- MgO.4ZrO2 oxide and has a composition which consists of, by weight, 20-50% 2MgO.SiO2 and 50-80% MgO.4ZrO2 and in which 2MgO.SiO2+MgO.4ZrO2=100 is satisfied. A heat resisting member is formed by thermally spraying the above coating material on a heat resisting metallic material or parts having metallic coating layer excellent in high temp. corrosion resistance. The grain size of the oxide as coating material is regulated to 5-500mum, and particularly, it is preferable to regulate average grain size to 10-100mum. This thermal spraying material has superior mechanical strength. By using this thermally sprayed layer, a turbine blade, etc., having excellent thermal shield effect and heat resistance can be obtained.

摘要： PURPOSE:To obtain a roll having wear resistance and preventing surface roughening by arranging a build-up metal layer dispersing TiC plating Ni or Co in the matrix alloy in austenitic stainless steel, Ni base alloy or Co base alloy on the surface of roll barrel part. CONSTITUTION:The TiC powder obtd. by plating Ni or Co contains 20-80vol% in the austenitic stainless steel, Ni base alloy or Co base alloy. Further, the matrix powder adding the TiC powder plating Ni or Co to the austenitic stainless steel, Ni base alloy or Co base alloy powder is build-up welded on the surface of roll barrel part with plasma arc welding method. The TiC powder is plated with Ni or Co and difference of sp. gr. between this and the matrix alloy powder, is made to small and floating of TiC is prevented and matching with the matrix metal becomes good and addition to the molten pool of the TiC is made to easy. By this method, the roll having wear resistance without surface roughening is obtd. and the service life of the roll and the productivity can be improved.

摘要： PROBLEM TO BE SOLVED: To improve the productivity of refractory brick in a method for producing refractory brick having a laminated structure and a continuous slip casting apparatus used in the method and a manufacturing yield by suppressing cracking and defective joining on an extension plane. SOLUTION: In the method for producing the refractory brick in which the refractory brick having the laminated structure in which at least two kinds of refractory layers different in at least one of porosity and composition are laminated is produced by supplying different kinds of slurry-like refractory raw materials for forming the different kinds of refractory layers in turn into a form and slip-casting, when the kind of the refractory raw material supplied into the form is changed over from one refractory raw material to another refractory raw material, after mixed slurry comprising one refractory raw material and another refractory raw material is supplied to form a cushioning layer, the supply of another refractory raw material is started, and another refractory raw material is supplied onto the cushioning layer so that the variation of the thickness of the layer of the refractory raw material supplied already into the form when the supply of another refractory raw material is started is within a prescribed range.

摘要： PURPOSE:To prolong the life of the circular blade for a steel sheet trimmer consisting of a tool steel as a base material by subjecting a high hard TiC-TiN coating film to coating treatment. CONSTITUTION:This circular blade for the steel sheet trimmer is formed with a film consisting of TiC and TiN and contg. 20 to 90wt.% TiC. Since this circular blade is highly resistant to wear and peeling, the circular blade withstands long-term use. The circular blade is capable of shearing the steel sheet to the surface shape approximate to a target shape and, therefore, the quality of the steel sheet is improved and further, the improvement in productivity by decreased frequencies of the exchange of the circular blade and the decrease in operation load are resulted.
