摘要： PURPOSE:To restrain wear of heat resistant refractory and to enable stable casting by inserting the wear resistant refractory having high hardness at high temp. more than that of a cast strip between frame edge parts formed at both side edges contacting with a circular body and heat insulating refractory supported interval of both frame edge parts. CONSTITUTION:The surface of the frame edge part 9 is sufficiently cooled with cooling water flowing in coolant passage 11 and molten steel is cooled in there, to develop the solidified shell. The heat resistant refractory 10 held in the frame edge part 9 is brought the surface into contact with the molten steel, but as it has low thermal conductivity, the solidification of the molten steel is not developed on the heat insulating refractory 10. The solidified shell developed at the frame edge part 9 grows and a part thereof expects to extend to the face of heat resistant refractory 10, but growth of the solidified shell is stopped on the surface of the wear resistant refractory 12 having high hardless at high temp. arranged at the boundary of the frame edge part 9 and heat resistant refractory 10. As the solidified shell is not directly brought into contact with the heat resistant refractory 10, the heat resistant refractory 10 is scarcely worn with the solidified shell.

摘要： PURPOSE:To pour uniform molten metal flow without developing any molten metal penetration, etc., between a pouring nozzle and belts by satisfying the relational inequalities on the pouring nozzle. CONSTITUTION:The nozzle is composed of an upper nozzle 7 and a lower nozzle and discharging hole of the upper nozzle is inserted into the upper part of the lower nozzle. Then, the nozzle is to satisfy the undermentioned relational inequalities. (x-y)/2>=5mm, 2mm =9,800mm>=P>=150mm, wherein, x: cast slab thickness (mm), y: thickness at end part of the lower nozzle containing refractory thickness (mm), z: slit gap to cast slab thickness direction at end part of the lower nozzle (mm), l: distance from end part of the lower nozzle to the position, which the whole thickness of the lower nozzle refractory becomes the equal with the cast slab thickness (x) (mm), P: distance from discharging hole of the upper nozzle 7 to the end part of the lower nozzle (mm). By this method, the uniform molten metal flow can be poured and the service lives of the nozzle and the belt are extended.

摘要： PROBLEM TO BE SOLVED: To prevent the holding force of irregular refractories from lowering even at the time of temperature rise by specifying the open angine between anchor branches for holding the irregular refractories on the eall of a ceramic furnace. SOLUTION: A supporting anchor 1 comprises an anchor branch part 1b obtained by splitting the upper half of a tubular body, e.g. a steel pipe, vertically and bending it into reverse V-shape and an achor strut 1a at the lower half of the tubular body wherein the open angle between the branch parts is set in the range of 190 deg.-350 deg.. Alternatively, the anchor branch part 1c of the tubular body is welded to the anchor strut 1a thereof or a substantially L-shaped anchor branch part 1d is welded to the anchor strut 1a of the tubular body and then the anchor branch part 1c is welded. The supporting anchors are not limited to a tubular body such as a steel pipe, but they can be produced by machining a steel rod, a rectangular pipe, a section steel, or the like. Shaping method is not limited to bending or welding but it can be assembled through integral molding.

摘要： PROBLEM TO BE SOLVED: To unnecessitate the work with a skilled technician and to shorten the time by fitting a dummy tuyere to a tuyere at the bedding part of a ladle, fixing it with a fixed metal tool, pouring castable refractory to the lower height than the upper end of the dummy tuyere and removing the dummy tuyere. SOLUTION: Before pouring the castable refractory, the dummy tuyere 11 is fitted to the tuyere 5 and fixed with the fixed metal tool 12, and contacting surface with a tuyere brick 6 is closely stuck with a fastening metal tool 13 and firmly fastened. After fitting the dummy tuyere 11, immediately, the pouring of the castable refractory 4 can be executed. At the time of pouring the castable refractory 4, it is most important to pour the castable refractory so that the upper surface level of the castable refractory 4 does not exceed the upper end of the dummy tuyere 11. Then, after completing the hardening of the castable refractory 4 or just before completing the hardening thereof, the dummy tuyere 11 is taken out from the tuyere 5. The dummy tuyere 11 is formed of a cylindrical member made of steel or plastics, etc., with the shape conforming to the tuyere shape.

摘要： PURPOSE:To increase continued length of life in continuous casting and to realize the stable casting by supporting refractory between both frame parts formed at both edge parts contacting with circulating body and constituting the refractory of assemble of a heat insulating refractory and a wear resistant refractory. CONSTITUTION:Molten metal is held with one pair of the facing arranged circulating bodies and one pair of short side plates positioned at both edge parts between of them to form strip continuous casting machine by constituting the casting space. In this short side plate, the refractory 10 is supported with both frame parts 9 formed at both end parts contacting with the circulating body. The refractory 10 is constituted with the assemble of the heat insulating refractory layer 10a and the wear resistant refractory layer 10b arranged on this.
