    • PURPOSE:To avoid any dangerous collapse of a partition wall of refractory material under a condition of earthquake by a method wherein some heat- resistant steel pipes and metallic nets are buried in a lateral direction within the partition wall of refractory material in a furnace. CONSTITUTION:Some castable retractory materials 8 with heat-resistant metallic nets therein having some triangular irregular grooves while holding some refractory materials 2 are placed on a hearth, they are adhered by beat-resistant mortars 10 and they are piled up. Ceramic fiber materials 6 are filled at both ends of a refractory partition panel 12 including two heat-resistant steel pipes 2 and piled up there. Some castable formed refractory materials 8 having some heat-resistant metallic nets are piled up on the ceramic fibers. A formed refractory partition wail panel 7 having one heat-resistant steel pipe having some refractory castables and ceramic castable material at the uppermost part of the partition wall is piled up. With such an arrangement, a superior refractory material shape having anti-earthquake characteristic can be attained for a partition wall for a heating furnace, a melting furnace, a soaking furnace and an annealing furnace for petroleum chemical industry.
