    摘要： A method for manufacturing a plate inorganic nonmetal material by using a molten slag by introducing the molten slag into a pool for preserving heat and modifying, wherein a temperature of the molten slag is 1450° C.-1600° C., and modifying a viscosity and/or a color of the molten slag according to requirements of the product manufactured. The modified molten slag is introduced into a float process furnace using tin or tin alloy carrier forming a plate of inorganic nonmetal material which is discharged at 1000-1300° C. The plate is maintained at 600° C.-900° C. for 0.5-2 hours in a non-reducing atmosphere, and then cooled to a room temperature within 1-2 hours. An energy-saving and efficient method for comprehensively utilizing the blast furnace slag is provided. The produced plate inorganic nonmetal material has such characteristics as stable color quality, abrasion resistance, pressure resistance, strong adhesiveness, low coefficient of expansion and low shrinkage ratio.

    摘要： In a process for the preparation of cement from metallurgical slags, in which liquid slags from reduction processes and steelworks processes, e.g. blast furnace and converter slag, are mixed together and mixed with lime the procedure is such that in a first cooling phase at temperatures above 1000.degree. C., and preferably above 1200.degree. C., the cooling is slower than in a subsequent second cooling phase and that the solidified product obtained is granulated and/or ground in order to obtain directly cement with improved hydraulic properties, in particular increased final strength.

    摘要： The invention relates to a method for preparing a hydraulically settable cement base material starting from steel slags formed in a steel-making process, which method comprises the formation, in steel slags in the liquid state, of a ferrite gradient by adding a ferrite-precipitating compound, the separation, if required, of the high-ferrite fraction formed, the separation of at least the low-ferrite fraction formed, the cooling and the comminution thereof to obtain a hydraulically settable material. The ferrite-precipitating compound used has preferably acid components, and can expediently generate silicic acid. At least before the cooling of the low-ferrite fraction, the aluminum content of the liquid slag material is regulated by the addition of an aluminate-containing material, such as bauxite. The high-ferrite fraction separated can be returned to the steel-making process to reduce or remove the addition of a flux in the production of steel.

    摘要： A process for making a hardening agent for weak soil or sludge from steelmaking slag. About 5-30 wt. % of specified reforming agent selected from the group consisting of one or more of silicate rock, mineral, calamine, glass waste, foundry waste sand, waste brick, red mud, volcanic slag, iron oxide and mixtures thereof is added to a molten steelmaking slag, causing a reaction forming a reacted steelmaking slag. The reacted steelmaking slag is then rapidly cooled to form a powder. Iron is then removed from the powder and the powder is then mixed with from about 3-5% of a powder selected from the group consisting of one or more of lime, plaster and cement to form a hardening agent for weak soil or sludge.
