摘要： PROBLEM TO BE SOLVED: To obtain a method for measuring an air gap by a thermal flux detection of casting mold, and a thermal flux detector and a sensor in the same device. SOLUTION: A lubricous layer by a lubricant 57 is formed between a mold wall face W of casting mold and a melted steel, and an air gap 59 is naturally formed between the lubricous layer and the mold wall. From thermal flux q detected by a coaxial sensor 35 inserted into a thick direction of the mold wall and represented by expression q=(TH-TL)/R (however, R is thermal resistance of a matter between TH and TL); an internal temperature T1 of a mold wall part W detected at a tip of the coaxial sensor 35; and a solidus temperature TSL of melted steel, a temperature T2 on an interface of the mold wall and an air gap 59 and a temperature T3 on an interface of the lubricous layer and the air gap 59 are acquired. Thermal resistance R2 of the air gap 59 is acquired by expression q=(T3 -T2 )/R2 representing the thermal flux q in a thickness direction of the air gap 59, and a thickness d2 of the air gap is acquired by R2 =d2 /λ (λis thermal conductivity of the air gap).

摘要： PROBLEM TO BE SOLVED: To prevent splashing and to regulate the pouring flow of open pouring by constituting inlet refractories which constitute an inlet and have a through-hole of a flow regulating cylindrical section and a pouring nozzle part which is enclosed by the same, exists in the lower part of at the flow regulating cylindrical section and encloses the through-hole of the inlet refractories. SOLUTION: The flow regulating cylindrical section 3 made of the refractories having the through-hole 4 is arranged in the upper part and outer periphery of the pouring nozzle section 2. The flow regulating cylindrical section 3 is integrally composed of the refractories and the pouring nozzle section 2 is formed to the form that this section is inserted into the flow regulating cylindrical section 3 and, therefore, the external shape of the inlet refractories is determined by the shape of the flow regulating cylindrical section 3. The height above the inlet nozzle section 2 is required to be >=50 mm in order to sufficiently exhibit a flow regulating effect. When the top end of the flow regulating cylindrical section 3 is lower than the surface of the refractories at the bottom of the tundish and a large difference in level occurs, a pouring basin part is formed in the upper part of the flow regulating cylindrical section 3 and harmful vortexes are generated to splash the pouring flow and, therefore, the flow regulating cylindrical section 3 is so arranged as to obviate the occurrence of the difference in level.
