The product, and the invention can also make full use of the steel slag, turn waste into treasure, make the resource form a recycling cycle, reduce the cost, and do not use limestone, no calcination, no carbon dioxide emission, and more environmental protection. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a block diagram showing the process flow of the present invention. BEST MODE FOR CARRYING OUT THE INVENTION The steel slag three-in-one cement according to the present invention is made of 60-70% of steel slag and 30-40% by weight of auxiliary materials. Among them, the auxiliary material may be 100% clinker, or it may be bottom slag (also can be replaced by fly ash, this is equivalent) 25-40%, clinker 60-75% mixture, or coal gangue 60-70 %, gypsum 5-15%, clinker 15-25% mixture (70% coal gangue, 10% gypsum, 20% clinker is preferred), or clinker 80-90%, gypsum 5-10 %, 5-10% by weight of the cementitious material mixture (preferably 80% clinker, 10% gypsum, 10% gelling material). The formula can also be added with additives according to the quality of the steel slag. The additive is made of aluminum sulfate, ethylene glycol, curing agent, acrylic acid and amine, so that the finished cement can reach the national standard PC32. 5 cement standard and the quality is better.
钢渣是用于代替原来水泥加工过程中的半成品——熟料，当钢渣 磨细至比表面积为 450m2/Kg 以上时， 在整个配方中起活化作用， 随 着钢渣配比量的增加会使钢渣三合一水泥产品的成本降低但安定性 差， 而钢渣减少会使产品成本升高但安定性佳。辅料（可含炉底渣或 粉煤灰）在整个配方中起与钢渣中和、在化学特性上互补的作用， 随 着辅料配比量的增加会使钢渣三合一水泥产品成本高、安定性佳但强 度差， 辅料减少则会使产品成本降低、安定性差但强度佳。辅料'中的 减胶凝材料对物料起激发活性作用，使产品得到活性和安定性， 减胶 凝材料可不经过粗磨和细磨， 在脉冲混合均质中加入。 因此， 钢渣三 合一水泥具体配方选择钢渣 70%, 辅料 30%， 或钢渣 65%, 辅料 35% 为较佳。 Steel slag is used to replace the semi-finished product in the original cement processing process - clinker. When the steel slag is ground to a specific surface area of 450 m 2 /Kg or more, it will activate in the whole formula, and the amount of steel slag will increase. The cost of steel slag three-in-one cement products is reduced but the stability is poor, while the reduction of steel slag will increase the cost of the product but the stability is good. Excipients (which may contain bottom slag or fly ash) play a role in neutralizing steel slag and complementing chemical properties throughout the formulation. As the proportion of auxiliary materials increases, the cost of steel slag three-in-one cement products is high and stable. Goodness but poor strength, reduced auxiliary materials will reduce product cost, poor stability but good strength. The reduced gelling material in the auxiliary material acts to excite the material to make the product active and stable, and the reduced gelling material can be added in the pulse mixing homogenization without coarse grinding and fine grinding. Therefore, the specific formula of steel slag three-in-one cement is 70% steel slag, 30% auxiliary material, or 65% steel slag, and 35% auxiliary material is preferred.
钢渣三合一水泥的加工工艺如图 1所示： The processing technology of steel slag three-in-one cement is shown in Figure 1:
先通过烘干系统将钢渣、 辅料分别烘干至含水量 2-3%。 烘干系 统在生产品工艺流程中主要是对产品所需的物料进行烘干，以达到物 料的含永率在 3%以内， 保障了生产工艺中规定的技术指标。 First, the steel slag and auxiliary materials are respectively dried to a water content of 2-3% through a drying system. The drying system mainly processes the materials required for the product in the raw product process to achieve the object. The material contains a permanent rate of less than 3%, which guarantees the technical specifications specified in the production process.
接着，通过粗磨系统分别将烘干后的物料进行粗磨， 至颗粒直径 为 5mm以下， 为下道工艺做好前期的预处理。如果辅料中采用减胶凝 材料， 可不经过粗磨和细磨为好， 而在脉冲混合均质中加入。 Then, the dried material is coarsely ground by a coarse grinding system to a particle diameter of 5 mm or less, and the pre-treatment is performed for the next process. If the binder is used in the auxiliary material, it may be added in the pulse mixing homogenization without coarse grinding and fine grinding.
再在配料系统中按钢渣 60-70%、 辅料 30-40%的比例进行配料。 配料系统是全部生产工艺流程中的重中之重，准确的配料才能保证产 品的质量， 所以该系统在工艺流程中的大料配料计量精度达到小于 0. 5%的精度， 小料配料计量精度达到小于 0. 2%的精度。 In the batching system, the ingredients are proportioned by 60-70% steel slag and 30-40% of auxiliary materials. The batching system is the most important in the whole production process, and the accurate batching can ensure the quality of the product. Therefore, the measurement accuracy of the bulk material in the process is less than 0.5% precision, the measurement accuracy of the small material batching 2%的精度。 Achieved less than 0.2% accuracy.
并通过粉磨系统，将配好的物料进行细磨， 该系统采用相向旋转 超重力粉磨工艺，在其物理力学、化学及瞬间超高温等作用的激发下， 磨粉细度达到比表面积为 450m2/Kg 以上， 使物料的各种性能产生变 化， 达到国标 PC32. 5水泥标准。 And through the grinding system, the prepared material is finely ground. The system adopts the phase-rotating super-gravity grinding process. Under the excitation of physical mechanics, chemistry and instantaneous ultra-high temperature, the fineness of the grinding powder reaches the specific surface area. Above 450m 2 /Kg, the various properties of the material are changed to meet the national standard PC32. 5 cement standard.
然后，在脉冲混合均质系统中进行脉冲均质混合， 由于钢渣三合 一水泥的配料较复杂，它由多种材料和成份组成，为使其成份充分特 用该脉冲混合系统。如果辅料中采用减胶凝材料，在脉冲混合均质中 直接加入为佳。经上述粉磨后的细磨，再经该系统混合均质至均匀度 为 CV<0. 3%, 才能达到最终产品的质量要求。 Then, pulse homogenization is carried out in a pulse mixing homogenization system. Since the composition of the steel slag three-in-one cement is complicated, it is composed of a plurality of materials and components, and the pulse mixing system is fully utilized for its components. If the binder is used in the auxiliary material, it is better to add it directly in the pulse mixing homogenization. After the fine grinding after the above grinding, the system is homogenized until the uniformity is CV < 0.3%, in order to achieve the quality requirements of the final product.
最后，可根据需要进入包装系统包装成袋，或散装进入物料系统。 Finally, it can be packaged into bags as needed into the packaging system, or bulk into the material system.
