An integrated submerged entry nozzle for thin slab continuous casting has a plate member 12 corresponding to the lower plate of a slide gate and a nozzle member 11 having a flat molten steel passage section in the part to be submerged into molten steel of at least the tip, the both 11. 12 being integrated together by the use of an organic adhesive. The plate member 12 and the nozzle member 11 are separately formed followed by baking or firing, the both 11, 12 are adhered together by the use of an organic adhesive, the adhesive is dried, the outside is covered with a shell, and refractory mortar is filled in the space. Thereafter, a refractory ring 28 is adhered in such a manner as to cover the inside of the adhesive joint part followed by drying.

Integrated submerged entry nozzle and its manufacture

In a flat casting nozzle 10 having a taper 13, the position of the terminal end 14 of the taper 13 formed on the long edge side and the position of the terminal end 17 of a taper 16 formed on the short edge side are mutually shifted.

Flat formed submerged entry nozzle for continuous casting of steel

Provided is a refractory for casting which contains clinker having a mineral crystal phase consisting essentially of mullite and baddeleyite. The refractory for casting has excellent in a thermal-shock resistance, corrosion resistance and strength. The refractory for casting is manufactured from a raw material containing a refractory composition and an organic binder, wherein the refractory composition comprises
