摘要： PURPOSE:To accelerate the aging of slag cooled slowly in a blast furnace by adding a surfactant combined optionally with an oxidizing agent to the slag. CONSTITUTION:A surfactant is added to slag cooled slowly in a blast furnace by >=0.005wt%. In order to produce a sufficient effect, the surfactant is added by >=0.01wt%. By the wetting and penetrating actions of the surfactant, an aqueous soln. contg. dissolved oxygen penetrates and disperses rapidly into the slag all over, so the oxidation of the slag is accelerated, and the aging is completed. When >=0.01wt% oxidizing agent is further added, the oxidizing action of the agent activates said oxidation with oxygen dissolved in the aqueous soln., so the oxidation of the slag is synergistically accelerated. A nonionic surfactant is most suitable for use as the surfactant, and an Mn compound, hydrogen peroxide, org. peroxide, an iron compound, a nitrogen compound or the like is used as the oxidizing agent.

摘要： PURPOSE:To accelerate the aging of slag cooled slowly in a blast furnace by adding an oxidizing agent to the slag. CONSTITUTION:MnO2 as an oxidizing agent is dispersed in water and added to slag cooled slowly in a blast furnace to complete the aging of the slag in a short time. The amount of MnO2 to be added is >=0.01wt%, and in order to produce a sufficient effect, MnO2 is added by >=0.02wt%. A reaction for finally converting CaS in the slag into a sexivalent S compound represented by the equation is accelerated, and the production of yellow water is prevented. Hydrogen peroxide, org. peroxide, an iorn compound, a nitrogen compound or the like may be used as the oxidizing agent in place of MnO2.

摘要： PURPOSE:To accelerate the aging of slag cooled slowly in a blast furnace by combinedly adding a surfactant and sulfite to the slag. CONSTITUTION:When sulfite is added to slag cooled slowly in a blast furnace, free S produced from CaS in the slag reacts with SO3 in accordance with the equation, so no polysulfide is produced to prevent the production of yellow water. When a surfactant is further added, by the wetting and penetrating actions of the surfactant, an aqueous soln. contg. dissolved sulfite penetrates and disperses rapidly into the slag all over. As a result, said reaction represented by the equation is efficiently carried out, and a little sulfite shows a significant aging accelerating effect. The sulfite is potassium sulfite, sodium sulfite, ammonium sulfite or the like, and any of anionic, cationic, amphoteric and nonionic surfactants may be used as the surfactant.
摘要翻译：目的：通过在炉渣中合并加入表面活性剂和亚硫酸盐，在高炉中加快缓慢冷却的炉渣老化。构成：当将高炉中缓慢冷却的亚硫酸盐加入炉渣中时，炉渣中的CaS产生的游离S与SO3 <2->反应，因此不会产生多硫化物以防止产生黄色水。当进一步加入表面活性剂时，通过表面活性剂的润湿和渗透作用，可以使用水溶胶。 contg。溶解的亚硫酸盐渗透并快速渗透到炉渣中。结果，由方程式表示的所述反应被有效地进行，少量的亚硫酸盐显示出显着的老化加速效果。亚硫酸盐是亚硫酸钾，亚硫酸钠，亚硫酸铵等，并且阴离子，阳离子，两性和非离子表面活性剂中的任何一种可以用作表面活性剂。

CONSTITUTION:The main raw material 4 for the sintered ore is gurried from each storage tank and is charged into a primary mixer 7 and is mixed. The pulverous iron ore 1 contg. >=70% =1 or 2 kinds among limestone, quicklime and slaked lime having =1.0wt% of the sintered raw material. The limestone powder, etc. are used at >=0.5wt% thereof. The coarse granular ore such as the sintered returns of the blast furnace as the nucleus for pelletization is used at a ratio of 20/80-60/40 with respect to the total weight of the pulverous ore and the limestone. Such pellets 6 are mixed with the main raw material mixture from the mixer 7 in a secondary mixer 8. The sintering raw material having excellent air permeability is thus obtd.

摘要： PURPOSE:A slag powder, capable of bonding to a synthetic resin firmly and giving a composite material having a sufficient strength as a filler, and prepared by eliminating free lime from a converter slag, wetting the slag powder free from a consolidated part with moisture, mixing the powder with a carboxylic acid or a salt thereof, and drying the resultant mixture. CONSTITUTION:A converter slag, from which free lime is eliminated by modifying treatment such as blowing a gas containing oxygen thereinto, is pulverized, and water in an amount to moisten the particle surface is added to form a thin layer consisting of a silicate hydrate and calcium hydroxide, which is then mixed with a carboxylic acid or a salt thereof and reacted with the calcium hydroxide to form an active terminal part of a calcium carboxylate on the surface of the particle. The resultant powder is then dried in the stream of a gas containing carbon dioxide. EFFECT:A synthetic resin and the converter slag powder are bonded to each other via the active terminal part directly or indirectly to give a composite material having a high strength.

摘要： PURPOSE:To obtain a stable synthetic resin material, easily handleable with a high fluidity and without causing aggregation of the powder in the air and cracks due to expansion of the powder after filling, by using a pulverized converter slag wherein the free lime is eliminated by modifying treatment. CONSTITUTION:A converter slag within the free lime is eliminated by modifying treatment, e.g. blowing a gas containing oxygen thereinto, is pulverized by a pulverizer to a particle size of preferably several tens of mu of less which is favorable for a filler. The resultant fine powder is then mixed with a synthetic resin and molded. Even the modified slag in a high filling ratio over 200pts.wt. per 100pts. wt. the synthetic resin can be readily molded. EFFECT:A stable synthetic resin composite material of high specific gravity can be obtained since an unstable component reactive with moisture or CO2 permeating the resin is not contained.
