Abstract
PURPOSE: To improve adhesivity of a lining layer by flame spraying and to bond the layer to a wall of a coke oven, by removing attached carbon, etc. from the wall surface of the coke oven through exidizing flame of a flame gun, followed by flame spraying of refractory powder.
CONSTITUTION: After coke is taken out from a coke oven by a coke pushing machime, carbon and tar deposited on a repairable part of a wall of the coke oven is removed by oxidizing combustion of a flame gun. The wall is coated with fefractory powder by flame spraying to form a lining layer, which has improved adsecitity. When the refractory powder is applied by flame spraying to the wall of the coke oven while it and hot bed are maintained at a temperature of not less than 400°C by oxidizing flame in removing carbon, the linining layer has improved adhesivity.
