面７ａ。In the figure, reference numeral 7 denotes a plate body provided with molten metal discharge holes 8, which is made of high-strength ceramics such as silicon nitride ceramics, silicon carbide ceramics, zirconia ceramics, etc. A rectangular recess 9 surrounding the molten metal discharge hole 8 is provided on the sliding surface 7a of the plate body 7. A rectangular plate-shaped inlay 1 is provided in the recess 9 of the plate body 7 with a molten metal discharge hole 10 connected to the molten metal discharge hole 8.
1 are removably fitted through an intervening material 12 such as mortar or cushioning material. The inlay 11 constitutes a gate plate refractory together with the plate body 7, and is made of highly corrosion-resistant ceramics such as dense alumina ceramics, alumina/graphite ceramics, zirconia ceramics, magnesia/spinel ceramics, etc. Furthermore, the sliding surface 11a of the inlay 11 is flush with the sliding surface 7a of the plate body 7, and is also the contact surface 7a of both tanks.
