SLIDING NOZZLE PLATE PRODUCTION METHOD
The objective of the invention is to provide a production method and a plate for a sliding nozzle plate comprising a refractory wherein the occurrence of cracks has been suppressed even when high temperature heat treatment is performed. This sliding nozzle plate production method is characterized by comprising: mixing (S1 and S2), when 100% by mass is the total, 2 to 23% by mass of Al4SiC4, and 2 to 10% by mass of a carbon material, the remainder being a phenol resin with a moisture content of 1% or lower and one or more from among alumina, alumina-zirconia, zirconia mullite, magnesia, and magnesia-spinel; and thereafter, heat treating (S4 and S5) at a heating temperature of 150 to 1,400 degC. The plate of the present invention is characterized by being produced by this production method.
本发明提供一种即使进行高温下的热处理也能抑制裂纹产生的由耐火物构成的滑动喷嘴用板的制造方法及板。本发明的滑动喷嘴用板的制造方法的特征在于：在以整体为100质量％时，将2～23质量％的Al4SiC4，2～10质量％的碳材料，剩余部分为氧化铝、氧化铝‑氧化锆、锆莫来石、氧化镁、氧化镁－尖晶石中的1种以上以及水分含量为1％以下的酚醛树脂进行混合(S1～S2)，然后，在150～1400℃的加热温度下进行热处理(S4～S5)。本发明的板的特征在于：利用该制造方法制造而成。
