DRY TYPE SPRAY MATERIAL FOR HOT WORKING, AND HOT WORKING DRY TYPE SPRAY CONSTRUCTION METHOD
To enhance corrosion resistance in a dry type spray material for hot working and a hot working dry type spray construction method.SOLUTION: In a hot working dry type spray construction method by force-feeding a blended material containing a fire resistant material and a binder other than a pitch toward a spray nozzle through a piping, adding water at a tip of the spray nozzle and spraying the same at hot working, the blended material contains magnesia lime stone with particle diameter of 0.075 mm or more and less than 1 mm of 10 mass% to 50 mass% in 100 mass% of total amount of the fire resistant material and the binder, and content of the magnesia lime stone with particle diameter of less than 0.075 mm is 35 mass% or less including 0 in 100 mass% of total amount of the fire resistant material and the binder.SELECTED DRAWING: None
【課題】熱間用乾式吹付材及び熱間乾式吹付施工方法において、耐食性を向上させる。【解決手段】耐火材料と、ピッチを除くバインダーとを含む配合物を、配管を通じて吹付ノズルに向けて圧送し、前記吹付ノズルの先端部において水を添加して熱間で吹き付ける熱間乾式吹付施工方法において、前記配合物は、前記耐火材料及び前記バインダーの合量１００質量％中において、粒径０．０７５ｍｍ以上１ｍｍ未満の苦土石灰石を１０質量％以上５０質量％以下含み、前記耐火材料及び前記バインダーの合量１００質量％中において、粒径０．０７５ｍｍ未満の苦土石灰石の含有量が３５質量％以下（０を含む。）である。【選択図】なし
