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

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.
