SPRAYING METHOD OF MONOLITHIC REFRACTORY FOR COKE OVEN CARBONIZATION CHAMBER AND SPRAY MATERIAL USED IN THE SAME
To improve stability in spraying and to improve workability in leveling work, in a spraying method of a monolithic refractory for a coke oven carbonization chamber by disposing a water injector in a material conveying pipe from a material feeder to a tip spray nozzle, and injecting construction water to a spray material conveyed through the material conveying pipe from the water injector.SOLUTION: In a spraying method of a monolithic refractory for coke oven carbonization chamber by disposing a water injector 7 in a material conveying pipe 5 from a material feeder 1 to a tip spray nozzle 4, and injecting construction water to a spray material conveyed through the material conveying pipe from the water injector, a ratio (flow rate of construction water conveying gas/flow rate of spray material conveying gas) of a flow rate (Nm/min) of a construction water conveying gas for conveying construction water introduced to the water injector 7 and a flow rate (Nm/min) of spray material conveying gas for conveying the spray material is 0.07 or more and 2 or less, and a compression degree of the spray material is 15% or more and 32% or less.SELECTED DRAWING: Figure 1
【課題】材料供給機から先端吹付けノズルに至る材料搬送管に注水器を設け、この注水器から材料搬送管内を搬送される吹付け材料に施工水を注水するコークス炉炭化室用不定形耐火物の吹付け施工方法において、その吹付け施工の安定性を向上させるとともに均し作業の作業性を向上させる。【解決手段】材料供給機１から先端吹付けノズル４に至る材料搬送管５に注水器７を設け、この注水器から材料搬送管内を搬送される吹付け材料に施工水を注水するコークス炉炭化室用不定形耐火物の吹付け施工方法において、注水器７に導入される施工水を搬送するための施工水搬送用ガスの流量（Ｎｍ３／ｍｉｎ）と、吹付け材料を搬送するための吹付け材料搬送用ガスの流量（Ｎｍ３／ｍｉｎ）との比（施工水搬送用ガスの流量／吹付け材料搬送用ガスの流量）を０．０７以上２以下とし、かつ、吹付け材料の圧縮度を１５％以上３２％以下とする。【選択図】図１
