Construction methods that strengthen fireproof blocks are mainly used.

を助長する結果となっている。[Problems to be Solved by the Invention] A defect of the monolithic refractory block is that it is susceptible to temperature changes and easily cracks. Therefore, in order to improve the spall resistance, we are trying to improve the quality of the monolithic refractory itself, and also to ensure that even if it cracks, it will not peel or fall off.
)-old 3: prime 1 +-hn/l
W n) a control d a- flea +++ implantation is being carried out. Monolithic refractory blocks with steel reinforcement embedded in them are prone to cracking due to temperature changes or differences in thermal expansion. When cracks occur, high-temperature gases from the furnace enter the cracked areas, causing oxidation damage or damage to the steel reinforcement. It melted and was eventually cut, peeling off and falling off, resulting in a short lifespan. In order to improve the above-mentioned drawbacks caused by the difference in coefficient of thermal expansion between the monolithic refractory and the reinforcing material, various measures have been taken to absorb the expansion of the reinforcing material. For example, methods have been used to apply paraffin or tar to the surface of the reinforcing material, or to cover the surface of the reinforcing material with vinyl tape. This has resulted in the occurrence of cracks in monolithic fireproof blocks.
