BURNING FIXTURE

摘要

PURPOSE:To provide a cost-reduced burning fixture of superior durability wherein the deterioration of a thermal spray deposit layer due to repeated use is prevented and the reaction with material to be burnt does not occur. CONSTITUTION:A highly pure magnesia spray deposit layer 3 is formed on a surface of an electrofused magnesia backing board 2. The highly pure magnesia spray deposit layer formed in such a manner does not have possibilities of reacting with material to be burnt and is free from problems of cracks, hair cracks and peals caused by repeated use. Large sized fixtures having superior durability can be made at reduced costs.
