Title:
REPAIRING MATERIAL FOR BRICK IN CARBONIZATION CHAMBER OF COKE OVEN AND REPAIRING METHOD
Document Type and Number:
Japanese Patent JP3619689
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide the repairing material for the brick in the carbonization chamber of the coke oven, which is used at the time of repairing a space due to the difference between thermal expansion coefficients of a metallic part of an oven entrance and refractory brick in a carbonization chamber of a coke oven, surface deterioration of the refractory brick due to its thermal history or wear, a through-hole in the refractory brick, or the like, and has high adhesiveness and exhibits an excellent repairing effect over a long period and also to provide the repairing method using the same.
SOLUTION: This repairing material is a blend comprising: (a) 100 pts.wt. of mortar; (b) 0.1 to 10 pts.wt. of a powdery component consisting of 70 to 100 wt.% of at least one powdery metal compound selected from compounds of Co, Ni and Al and 0 to 30 wt.% of at least one powdery metal compound selected from compounds of Ca, Mg, Zn, Sr, Ba, Fe, V, Pb, Cu and Ti; and (c) 2 to 50 pts.wt. of a liquid component consisting of 1 to 30 wt.% of SiO2, 3 to 34 wt.% of Na2O and/or K2O, 1.5 to 12 wt.% of B2O3, 0.3 to 4 wt.% of P2O5 and the balance of water. This repairing method comprises subjecting refractory brick to be repaired to hot coating with this blend, namely, the objective repairing material.
