Description
製造したSNプレートの形状は、図3に示すとおりで、この実施例では、A寸(長さ)=500mm,B寸(幅)=250mm,C寸(厚み)=40mmとした。また、本発明の実施例において特定耐火物1aは、全開位置と全閉位置におけるノズル孔の中心間S1を250mm、ノズル孔の孔径φを100mm、SNプレートの摺動方向の安全代α1を10mm、摺動方向と直交する方向の安全代α2を25mmとして、SNプレートの摺動方向の長さがS1+ φ + 2α1=370mm 、摺動方向と直交する方向の長さがφ + 2α2=150mmで規定される部分D4に厚み20mmにて配置した。このD4の部分は、図1で説明した使用重要部Dをカバーする。
特定耐火物として、アルミナ粉末:87質量%、カーボン粉末:3質量%、金属アルミニウム粉末:10質量%を混合し、乾燥、焼成したものを使用して、実施例1−1と同様にSNプレートを製造した。この実施例の特定耐火物の1500℃における熱膨張率は1.33%、音速弾性率は120GPaであった(表3、4の材質C)。一方、比較例では、上述の特定耐火物を、図3に示したSNプレートの全体に適用した。
特定耐火物として、マグネシア粉末:92質量%、カーボン粉末:3質量%、金属アルミニウム粉末:5質量%を混合し、乾燥、焼成したものを使用して、実施例1−1と同様にSNプレートを製造した。この実施例の特定耐火物の1500℃における熱膨張率は2.50%、音速弾性率は80GPaであった(表3、4の材質D)。一方、比較例では、上述の特定耐火物を、図3に示したSNプレートの全体に適用した。
