PURPOSE:To provide a heat storage chamber at a substantial cut in the labor and in a period of construction work by using machine power for laying a rider arch brick to the heat storage chamber and by dispensing with the leveling brick. CONSTITUTION:Rider arch bricks 1 for a heat storage chamber for a glass kiln is formed of either a unitized, arched brick 2 with a small thermal expansion coefficient and a low porosity or a rider arch brick made up of three to seven pieces. The upper side of unitized brick 2 or the assembly of brick when set in place is substantially horizontal. Each piece of the arch-forming brick has a thermal expansion coefficient of 5X10<-6>/ deg.C in a temperature range of from room temperature to 1,000 deg.C. Each piece of the arch-forming brick is formed by molding an amorphous refractory; the CaO content is less than 2wt.%, and the porosity is less than 20%. |
