摘要： A centrifugal injection machine comprises a rotor arm bearing at each of a pair of free ends a pivotably mounted container. A holder which retains a multiplicity of workpieces is insertable into a capsule or cavity within each container. The rotary arm contains a reservoir associated with each container or liquifying a charge of material. Upon rotation of the machine at a high velocity, the liquified material is transfered from the reservoir to the container in a vacuum and is pressurized therein as a result of centripetal acceleration. Upon the termination of a predetermined interval, a trip mechanism is activated to rotate the containers so that the molten liquid which has not been injected under pressure into recesses in the workpieces is ejected or discharged from the containers. The containers rotate within a vacuum chamber which is depressurized prior to the centrifuge operation.

摘要： This invention relates to the refining of steel external to a primary steelmaking vessel, for example in the ladle. More particularly, it is: A) a method of synthesizing a slag on the steel that (i) mitigates the detrimental effects of existing natural slag carried over from the primary steelmaking vessel, (ii) is low in specific bulk density, due to gas evolution and foaming, (iii) is suitable for refining of steel, and (iv) is not aggressive to the ladle refractory lining; B) a method, and composition for treating any primary slag that has entered the ladle; C) a method and composition for coating refractory linings. The present invention involves the manufacture in situ of a secondary ladle slag, the treating of ladle slag, and the protection of refractory linings by the addition of materials including calcium carbide, foaming agents such as one or more carbonates of calcium, magnesium, and sodium, and other components used to adjust slag composition. The properties of the secondary ladle slag are engineered using an optical basicity scale.

摘要： L'invention produit des compositions résistantes à l'humidité et à écoulement libre à partir de compositions normalement hygroscopiques au moyen d'un procédé qui consiste à mélanger le matériau hygroscopique avec un matériau de colmatage et à les traiter à chaud. Grâce à un réglage de l'addition du matériau de colmatage, de la durée du traitement thermique, et de la température du traitement thermique, le matériau de colmatage forme un revêtement vitreux sur le matériau hygroscopique, ledit revêtement étant imperméable à l'humidité tout en gardant des caractéristiques d'écoulement libre. L'invention prévoit notamment des compositions de titanate de sodium et de titanate de potassium résistantes à l'humidité et à écoulement libre dont l'absorption d'humidité est égale ou inférieure à environ 0,5 % en poids, au moyen d'un procédé qui consiste à mélanger du titanate de sodium ou du titanate de potassium avec un matériau de colmatage et à traiter le mélange à chaud.
