The invention discloses a masonry method for cross-over holes on a
coke oven of 7.63m, including the
coke oven of 7.63m and the cross-over holes on the oven. The holes comprise an upper layer and a lower layer, and an interlayer is arranged between the cross-over holes of the upper layer and the lower layer and provided with two through holes, the cross-over holes of the two
layers form mutually communicating channels by the through holes of the interlayer, the interlayer divides the cross-over hole of the upper layer into five areas, which are respectively the area above the right middle of the interlayer and four areas at two sides of the through holes of the interlayer, the whole area above the right middle of the interlayer is the masonry with silica
brick, and the upper cross-over hole is completely plugged,
waste gas is prevented from flowing to adjacent
flame paths; the four areas at two sides of the through holes of the interlayer adopt the
refractory materials with little density and the property of heat insulation for masonry and blockage. The masonry method of the invention limits hot
waste gas to flow on the upper part of a
combustion chamber, takes
advantage of the heat insulation property of the
refractory materials to stop
heat transfer, effectively prevents the temperature of the top space of the
coke oven from rising and further lowers the temperature of the top of the
coke oven and the consumption of gas.
