摘要： PROBLEM TO BE SOLVED: To increase adhesive strength between a siliceous stone brick used in a carbonization chamber of a coke oven and a repair material, and to enhance the service life. SOLUTION: A thermal spraying material contains refractory particles formed of unfired siliceous stone or silica sand, metal particles formed of metallic silicon, and a crystallization accelerator formed of one or more kinds of a sodium salt, potassium salt, and lithium salt. Preferable refractory particles have such a particle size that the content of particles having particle diameters of ≥600 μm is ≤10 wt%, the content of particles having particle diameters of 425-2,000 μm is 30-60 wt%, the content of particles having particle diameters of ≤75 μm is ≤10 wt%, and the remainder has particle diameters of 75-425 μm. The metallic silicon particles are added in an amount of 10-30 wt%, and have such a particle size that the content of particles having particle diameters of ≥150 μm is ≤10 wt%, the content of particles having particle diameters of 20-300 μm is 5-50 wt%, the content of particles having particle diameters of ≤2 μm is 10-40 wt%, and the remainder has particle diameters of 2-20 μm.

摘要： PROBLEM TO BE SOLVED: To provide an inexpensive sealant which inhibits wear of slurry-storing hopper, valves of a slurry feeder, etc. of a coke oven and offers a good sealability between a coal-feeding aperture and a lid. SOLUTION: The inexpensive sealant requires a low cost for pulverizing because it is soft and easily pulverized, inhibits wear of the valves of the slurry feeder etc., has low risk of inducing pneumoconiosis etc. because it is easily dissolved in body liquid when it enters human body and offers a good sealability between the coal-feeding aperture and the lid. The sealant comprises a calcium carbonate powder wherein particles of ≤75 μm, ≤45 μm and ≤10 μm account for ≥99 wt.%, ≥80 wt.% and ≥50 wt.%, respectively, or further comprises at most 5 wt.% at least one chosen from a water-reducing agent, a thickener and a bubble inhibitor.

摘要翻译：要解决的问题：提供一种廉价的密封剂，其抑制了浆料储存料斗的磨损，焦炉的浆料给料机的阀等，并且在给煤孔和盖之间提供了良好的密封性。
解决方案：廉价的密封剂需要低成本的粉碎，因为它是柔软的并且容易粉碎，抑制了浆料给料器等的阀门的磨损，因为它容易溶解在体液中，因此具有诱发肺尘埃沉着病的风险低当它进入人体并且在给煤孔和盖子之间提供良好的密封性时。密封剂包括碳酸钙粉末，其中≤75μm，≤45μm和≤10μm的颗粒分别占≥99重量％，≥80重量％和≥50重量％，或者还包含至多5重量％％至少一种选自减水剂，增稠剂和气泡抑制剂。版权所有（C）2006，JPO＆NCIPI
