<p>PURPOSE:To provide the subject brick preventing the breakage of glass melting oven bricks with the oven and improving the heat-storing effect of the brick by vertically disposing a flow path having the cross-sectional surface shape of an approximately triangle and also disposing a projection fitting into the groove of a rider portion thereof. CONSTITUTION:The three inside angle portions 1a of the main brick receiver 1 for the glass melting oven have round shapes and the angles at the three outside angle portions 1b of the main body 1 are 120 deg. (theta). The cross-sectional surface shape of the main body 1 has a flow path of approximately triangle and the second projections 3 for fitting into the slider portion 6 of glass-melting oven for prevention of deviation is disposed on the lower surface. The first projection 2 on the upper surface for the prevention of the deviation and the above-mentioned projection 3 permit to avoid the breakage of the bricks for the glass-melting oven with the melting oven and to improve the heat-storing effect of the bricks.</p> |
