摘要： PROBLEM TO BE SOLVED: To complete a swelling reaction even in steam aging of steelmaking slag containing powder at a high ratio.SOLUTION: The steelmaking slag 4 pulverized into particles so that 80 mass% or more of the particles has a diameter of 40 mm or less, is put in a slag vessel 1, and the slag vessel 1 and the steelmaking slag 4 are inserted in a pressure vessel 2. When pressurized steam is supplied in the pressure vessel 2, the inside of the pressure container is pressurized into a steam environment with a pressure of 0.1-1.96 MPa while condensed water is discharged to the outside of the pressure vessel by piping arranged inside a slag layer so that steam always flows from the slag layer surface to the slag layer center portion. After retention for a predetermined time, the pressure of the pressure vessel is lowered to an atmospheric pressure, and the slag is discharged. Since uniform steam aging can be carried out on the steelmaking slag containing powder at a high ratio and the swelling reaction is completed, application of the slag to a roadbed material for a road can be achieved, though this application is impossible conventionally.
摘要翻译：要解决的问题：即使在高比例的含有粉末的炼钢炉渣的蒸汽老化中也能完成溶胀反应。解决方案：将炉渣1放入炉渣容器1中，将造粒渣4粉碎成粒径为80质量％以上的直径为40mm以下的渣钢渣，渣渣1和炼钢渣4 插入压力容器2.当在压力容器2中供应加压蒸汽时，压力容器的内部被加压到压力为0.1-1.96MPa的蒸汽环境中，同时冷凝的水被排放到压力容器的外部通过布置在炉渣层内的管道使得蒸汽总是从炉渣层表面流到炉渣中心部分。在保持预定时间之后，将压力容器的压力降低至大气压，并将炉渣排出。由于可以在高比例的含炼钢渣的粉末中进行均匀的蒸汽老化，并且溶胀反应完成，所以可以实现将该渣施加到道路路基材料上，尽管这种应用是不可能的。版权所有（C）2012，JPO＆INPIT
