日本钢铁协会采用了367件标准:有生铁的化学分析;生铁的机械性能;气体(含HB)的化学分析。但是至今还没有炉渣标准。为便于操纵高炉流程,必须了解炉渣的成分、碱度、脱硫率、粘度、熔化温度。此外,炉渣被广泛用于生产水泥、建筑道路,用作混凝土的填料。为便于在对外市场上进行渣贸易,也必须了解渣的化学成分。现在采用x光方法测定炉渣化学成分。但是测定的可靠性不高。因此,日本钢铁协会在1988年10月建立12个炉渣的标准试样,这些炉渣含有最小和最大数量的SiO_2、Al_2O_3、CaO、MgO、MnO、TiO_2、T.Fe。以后该协会把标准试样减少到5个。日本钢铁协会收集适于制备标准试样的炉渣,放入金属坩埚内加以快速结晶成玻璃
The Japan Iron and Steel Association adopted 367 standards: chemical analysis of pig iron; mechanical properties of pig iron; and chemical analysis of gas (including HB). But so far there is no slag standard. To facilitate the operation of blast furnace process, we must understand the composition of slag, alkalinity, desulfurization rate, viscosity, melting temperature. In addition, the slag is widely used in the production of cement, building roads, as a concrete filler. In order to facilitate the trade of slag in the external market, it is also necessary to understand the chemical composition of the slag. The x-ray method is now used to determine the chemical composition of the slag. However, the reliability of the assay is not high. Therefore, the Japan Iron and Steel Institute established a standard sample of 12 slag in October 1988, which contained the smallest and the largest amounts of SiO 2, Al 2 O 3, CaO, MgO, MnO, TiO 2 and T.Fe. The association later reduced the number of standard samples to five. The Japan Iron and Steel Association collected slag suitable for the preparation of standard samples, placed in a metal crucible to rapidly crystallize into glass
