粉磨与特定激发剂的激发是炉渣胶凝材料技术的主要手段.研究表明:炼铅水淬炉渣的易磨性较差,在比表面积相近时,其粉磨单位电耗是高炉矿渣对应值的1.56倍;除铁炉渣的易磨性较未除铁炉渣的易磨性差,相同研磨时间内,除铁炉渣的比表面积普遍低于未除铁炉渣的对应值,在发生粉末结团与颗粒焊接现象前,除铁炉渣的极限比表面积为500m2/kg,未除铁炉的极限比表面积为550m2/kg;铁氧化物对炼铅水淬炉渣胶凝活性的影响在于其存在降低了炉渣胶凝材料中胶凝活性成份的含量,在激发剂足够多时,除铁炉渣的试块强度高于未除铁炉渣的试块强度,若激发剂数量不能满足需求,则除铁炉渣的试块强度低于未除铁炉渣的试块强度.
Grinding and activation of specific activator are the main means of slag cementing technology.Research shows that the lead-free water quenching slag is not easy to grind, and when the specific surface area is similar, the power consumption per unit of grinding is the corresponding value of blast furnace slag 1.56 times than that of the iron-free slag; the easy-to-wear property of the iron-removed slag is lower than that of the non-iron-removed slag; in the same grinding time, the specific surface area of the iron- Before welding, the ultimate specific surface area of iron-removing slag was 500m2 / kg and the ultimate specific surface area of non-iron removing furnace was 550m2 / kg. The influence of iron oxide on gelling activity of lead- The content of gelling active ingredient in the coagulation material is high when the activator is enough, the strength of the test piece of the iron-removing slag is higher than the strength of the test piece of the non-iron-removing slag, and if the quantity of the activator can not meet the requirement, Lower than the strength of the test piece without iron-removing slag.
