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

The present invention provides a recycle slide gate plate, said slide gate plate being connected to a lower portion of a molten metal container and used for sliding a plate to control a flow of molten metal drained from the molten metal container, comprising an upper plate and/or a lower plate obtained by polishing a sliding surface of a slide gate plate used at least one time, at a predetermined smoothness tolerance, a tubular ring fixed to a through hole obtained by cutting out a molten metal outlet portion of the upper plate and/or the lower plate having a projecting portion on a side opposite to a sliding surface of the upper plate and/or the lower plate, said projecting portion having a total height of a sum of a height dimension substantially equal to a height of a projecting portion of a new plate before use and a thickness dimension to be reduced by polishing out the sliding surface, the projecting portion being provided with a molten metal outlet hole formed inside the projecting portion, and a cushion plate fixed to a flat surface in a side opposite to the sliding surface of the upper plate and/or the lower plate, having a thickness necessary for making a thickness dimension of a flat surface reduced by polishing the upper plate and/or the lower plate be substantially equal to a thickness of the flat surface before polishing.

Recycled slide gate plate

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

Refractory for casting and method of manufacturing the same

A slide gate plate serving as a molten metal flow-rate control member for use in a molten metal discharging device, comprising an assembly of at least one stationary plate having a nozzle hole therein and a slide plate having a nozzle hole therein, the plates being designed so that one of the plates is thicker than the other plate by 1.5 mm or more. With this construction, the slide gate plate is reusable by polishing the sliding face off a worn plate for reuse.

Slide gate plate

According to the present invention, there is provided a sliding gate plate connected to a molten metal container, used as a part of a nozzle, for controlling a flow amount of molten metal in the molten metal container, comprising a main body of the sliding gate plate, having a through-hole at a section corresponding to a molten metal discharge control, and a cylinder having a ring-like fringe portion, and fit into the through-hole of the main body of the plate.
