  • Publication number: 20200189981
    Abstract: In a firing condition determination step S101a, as firing conditions for firing a refractory, an Fe2O3 amount (mass %) which is an Fe2O3 content, a target firing temperature T (° C.) to which the temperature of the refractory is raised when the refractory is fired and a continuous firing time t (hr) during which the firing is continued at the target firing temperature T are determined. The Fe2O3 amount, the target firing temperature T and the continuous firing time t are determined so as to satisfy all five formulas of 1.2<Fe2O3 amount ?2.5, 1250?T?1450, 0?t, P=0.0101×T+0.0913×t?12.3 and P>0.992×Fe2O3 amount+0.080.

  • Publication number: 20200080165
    Abstract: Workpieces are disposed between a pair of side walls in a heat treatment chamber. A centrifugal fan is disposed to face the workpieces inside the heat treatment chamber, and sucks gas from the workpiece side and generates air current. In regions at the respective side wall sides relative to an intermediate position between the pair of side walls, an air current regulation unit regulates the air current so as to restrict flows of the air current from the centrifugal fan to the respective side wall sides when a rotary blade of the centrifugal fan rotates in regions in which outer circumferential edge portions of the rotating rotary blade separate from the respective side walls, and allows the flows in regions in which the outer circumferential edge portions of the rotating rotary blade approach the respective side walls.
