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 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.

摘要： PROBLEM TO BE SOLVED: To manufacture steel slag of high quality, which does not swell even when exposed in air or water for a long time, and is used for applications such as materials for engineering works, by restraining generation of free CaO in solidified converter slag. SOLUTION: The method for manufacturing steel slag products with little formation of free CaO, is characterized by solidifying the slag in such a state that molar weight of calcium oxide molecules formed in the converter is 2 times as much as the molar weight of silicon oxide molecules, is 3 times as much as the molar weight of phosphoric oxide molecules, is 2 times as much as the molar weight of ferric oxide molecular, and is less than 1.15 times as little as a total molar weight of manganese oxide molecules and aluminum oxide molecules. The manufacturing method is also characterized by supplying oxygen from an oxygen nozzle 3, or adding a material containing much silicon oxide and phosphoric oxide, into the converter slag, in order to increase the ratio of ferric oxide, silicon oxide, or the like.

摘要： PURPOSE:To obtain a galvannealed steel sheet having superior weldability and coating suitability and excellent in workability by forming a plating layer, containing specific amounts of Al and Fe, on a cleaned steel sheet by a spray plating method. CONSTITUTION:A steel sheet is passed through a continuous annealing furnace to undergo surface cleaning by reduction and then introduced into a spray chamber, where atomized molten zinc is sprayed on the surface of the steel sheet to apply hot-dip galvanizing. The resulting hot-dip galvanized steel sheet is passed through an alloying furnace and heat-treated, by which alloying treatment is done by diffusing Fe in ferrite into the plated zinc layer. In the above spray plating method, the contents of Al and Fe in the resulting plating layer are regulated to 0.2-0.6wt.% and 8-12wt.%, respectively.

摘要： PURPOSE:To restrain stickness of bottom dross to a steel sheet by arranging a porous plate restraining the flow in a bath between a sink roll and the bottom part of a pot. CONSTITUTION:By arranging the porous plate 6 between the sink roll 2 and the bottom part of the pot in a zinc bath vessel, the flow in the bath generated by rotating the sink roll 2 and shifting the galvanized steel sheet 4 in the bath is shut off with the porous plate 6 to restrain the raise-up of the bottom dross 7. At the same time, as a part of the vigorous stream between the sink roll 2 and the porous plate 6 is flowed out from the holes 5 in the porous plate 6 and shifted to the lower part of the porous plate 6, the bottom dross 7 is not so much deposited at the lower part of the porous plate 6 that the raise-up of the bottom dross 7 generates. Then, the hole 5 arranged in the porous plate 6 is made to be about 10-50mm the hole diameter and the total area of the holes 5 is made to be in the range of 5-40% of the porous plate area. By this method, the galvanization having a little adhesion of the bottom dross is executed for a long term.
