Beschreibung
Zusammenfassung:	The present invention provides a precast-block refractory for coke ovens which has high hot strength and which underdoes stable expansion/contraction motion under a load at high temperature. That is,the present invention pertains to a siliceous precast-block refractory for coke ovens which is characterized by containing 0.3-2 mass% of a P2O5 component. 本发明提供种炼焦炉用预制块状耐火物，其在具有较高的高温强度的同时，高温时的负载下膨胀收缩挙动稳定。即，本发明的特征为，硅质炼焦炉用预制块状耐火物中，含有0.3质量％以上、2质量％以下的PO成分。
