摘要： Ceramic materials to be insert-cast contain not less than 65% of aluminum titanate as a crystalline phase, and have an average particle diameter of crystals thereof being not less than 10 µm, Young's modulus of 50 to 2,000 kgf/mm², compression strength of 5 to 40 kgf/mm², and porosity of 5 to 35%. These liners are free from cracking due to compression force during insert-casting, peeling-off during use, and facilitate insert-casting. In a port liner having a depressed portion at an outer peripheral surface, a reinforcement is filled into the depression which meets either one or both of requirements that differences in coefficient of thermal expansion at 800°C and Young's modulus between the reinforcement and the material of the liner body are in a range of ±0.1% and in a range of ±1,000 kgf/mm², respectively. Alternatively, the outer peripheral surface of the port liner body is worked to give an uneven surface where the liner is joined to a metal in insert-casting, or a stress-releasing slit may be formed in a wall of the port liner body. Further, the outer peripheral surface of the ceramic port liner body may be covered with a ceramic sheet which is irreveribly expandable by heating.

摘要翻译：插入陶瓷材料含有不小于65％的钛酸铝作为结晶相，其结晶的平均粒径不小于10μm，杨氏模量为50-2,000kgf / mm2 压缩强度为5〜40kgf / mm 2，孔隙率为5〜35％。这些衬垫在插入铸造期间由于压缩力而不会破裂，在使用期间剥离，并且易于嵌入铸造。在具有外周面的凹部的端口衬套中，将加强件填充到凹部中，其满足以下要求中的一个或两个要求：800℃下的热膨胀系数的差异以及钢筋与材料之间的杨氏模量衬垫体分别为+/- 0.1％的范围和+/- 1,000kgf / mm 2的范围内。或者，端口衬套主体的外周表面被加工成使得衬垫与插入件中的金属接合的不平坦表面，或者可以在端口衬里主体的壁中形成应力释放缝隙。此外，陶瓷端口衬垫体的外周面可以被不可靠地通过加热而不可扩展的陶瓷片覆盖。
