摘要： PROBLEM TO BE SOLVED: To provide a technology for producing a solidified body of steel-making slag, whereby elusion of fluorine from the slag-solidified body composed mainly of fluorine-containing steel-making slag is suppressed, producing the slag-solidified body having high-strength, and the solidified body of steel-making slag can be converted to a civil engineering material satisfying soil environmental standards, when being recycled after using. SOLUTION: The solidified body of steel-making slag is produced by the followings: using a raw material of the fluorine-containing steel-making slag having elusion pH of ≥11 as the steel-making slag; using further a solidifying agent selected from fine powders of blast furnace slag, cement, and the mixture of the fine powders of blast furnace slag with cement as a raw material; adding phosphoric acid or a phosphate to the mixture of the steel-making slag and the solidifying agent of blast furnace slag; preparing a ready-mixed concrete-like kneaded product by adding water to the resultant mixture; and solidifying whole of the kneaded product in a formwork etc. by curing.

摘要翻译：要解决的问题：为了提供一种用于生产炼钢渣凝固体的技术，由于主要由含氟炼钢渣组成的炉渣固化体的氟的脱落被抑制，具有高强度的凝固体，炼钢渣的凝固体可以在使用后再循环使用时，转化为满足土壤环境标准的土木工程材料。
解决方案：炼钢渣的固化体是通过以下方法制造的：使用具有浸出pH≥11的含氟炼钢渣的原料作为炼钢渣; 再使用选自高炉矿渣，水泥等细粉末和高炉矿渣粉末与水泥混合物作为原料的固化剂; 在炼钢渣和高炉渣固化剂的混合物中加入磷酸或磷酸盐; 通过向所得混合物中加入水来制备预混混合物混合物; 并通过固化在模板等中固化整个捏合的产品。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a technique capable of effectively suppressing the elution of fluorine from steelmaking slag with a small consumption of chemicals.
SOLUTION: The insolubilizing agent of fluorine in steelmaking slag is prepared by dissolving at least one of solid-state alkali (earth) metal phosphate selected from di-alkali metal hydrogen phosphate, tri-alkali metal phosphate and alkali earth metal phosphate into an acidic solution. The insolubilizing method of fluorine in steelmaking slag includes a process of adding the insolubilizing agent of fluorine prepared by dissolving the solid-state alkali (earth) metal phosphates into the acidic solution to the steelmaking slag. The solid-state alkali (earth) metal phosphate is dissolved into water only by such an degree as not to exceed several percents, therefore, is not suitable as the insolubilizing agent of fluorine, but is dissolved into an acidic solution to make the formation of a more concentrated solution possible, can effectively exhibit a fluorine-fixing effect to reduce the amount to be added.

摘要翻译：要解决的问题：提供一种能够有效地抑制来自炼钢渣的氟的洗脱，同时消耗少量化学物质的技术。解决方案：炼钢炉渣中氟的不溶化剂是通过将选自二碱金属磷酸氢盐，三碱金属磷酸盐和碱土金属磷酸盐的固态碱金属（土）金属磷酸盐中的至少一种溶解于酸性溶液。炼钢渣中氟的不溶化方法包括将固态碱金属（土）金属磷酸盐溶解在酸性溶液中而制备的氟不溶化剂加入到炼钢渣中的方法。固体碱金属（土）金属磷酸盐溶解在水中的程度不超过几个百分点，因此不适合作为氟的不溶解剂，而是溶解在酸性溶液中形成更浓缩的溶液可以有效地发挥氟固定效果以减少添加量。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To prevent fluorine incorporated into a soil remediation agent from being eluted into soil or ground water with respect to the soil remediation agent manufactured for the purpose of detoxifying trichloroethylene or hexavalent chromium by recovering particles containing iron abundantly from byproduct of industry and by refining the particles.
SOLUTION: The soil remediation agent is manufactured by adding a compound containing phosphoric acid or phosphate, and calcium ion to a mixture composed of particles which comprises a substance of eluting fluorine, metal iron, bivalent iron and water and by reacting calcium ion and fluorine to insolubilize fluorine.

摘要： PROBLEM TO BE SOLVED: To produce steel making slag of low fluorine elution conforming to soil environmental quality standards by inhibiting elution of fluorine from steel making slag containing fluorine into water.
SOLUTION: After cooling steel making slag containing fluorine to room temperature, an aqueous solution of phosphoric acid or of phosphate is added to the steel making slag. Water-soluble calcium ions are made to be present in the aqueous solution. In the aqueous solution, by reacting phosphate ions, calcium ions and fluorine ions, an apatite-based compound containing fluorine is formed, to which fluorine is fixed to prevent elution of fluorine.
