    摘要: In a lubricant composition suitable for use in the manufacture of aluminum alloys comprising lubricant base selected from the group consisting of solid lubricants, liquid lubricants, grease lubricants, emulsion lubricants, and dispersion lubricants, the improvement wherein the lubricant composition further comprises: an effective amount of water and surfactant. It is believed that mixing oil with water and surfactant provides a method for uniformly distributing the surface oxide at the meniscus for casting applications. Uniform distribution of the oxide at the meniscus reduces vertical fold formation that can lead to cracks in the aluminum ingot. In addition, the mixture promotes uniform heat transfer around the mold. Uniform heat transfer around the mold allows the solidifying aluminum alloy to stay in contact with the mold longer and form stronger ingot shells. A process for continuous or semi-continuous casting of aluminum alloys via the use of this lubricant composition is also disclosed.

    摘要: Apparatus for lubricating die and/or workpiece surfaces, the apparatus including a container adapted to capture a predetermined volume of lubricant. At least one nozzle is provided for spraying the volume of lubricant onto the die/workpiece surfaces when the volume is received from the container. A first valve is connected between the nozzle and container, and a reservoir of lubricant and a pump for circulating lubricant through the container and past the first valve at a relatively low pressure is provided, the circulation of lubricant occurring during a portion of a lubricating cycle when no lubricant is sprayed onto the die/workpiece surfaces. A second valve is located between the pump and container for interrupting the flow of lubricant past the first valve, and a blocking valve is located between the container and the reservoir for interrupting the flow of lubricant from the container. A piston is located within the container and an actuator is connected to the piston for moving the same within the container to direct the captured volume of lubricant from the container to the first valve at a pressure sufficient to open the first valve.

    摘要: Novel quaternary ammonium thiomolybdates are prepared by contacting an aqueous solution of a thiomolybdate salt with a solution of a water-insoluble quaternary ammonium salt in a water-immiscible organic solvent. For example, mixing a solution of dicocodimethylammonium chloride in toluene with an aqueous solution of potassium thiomolybdate results in a toluene solution containing dicocodimethylammonium thiomolybdate. These quaternary ammonium thiomolybdates find use as additives in motor oils and greases to enhance their antifriction characteristics.

    摘要: In a lubricant composition suitable for use in the manufacture of aluminum alloys comprising lubricant base selected from the group consisting of solid lubricants, liquid lubricants, grease lubricants, emulsion lubricants, and dispersion lubricants, the improvement wherein the lubricant composition further comprises: an effective amount of water and surfactant or water and a compound comprising phosphates, borates, fluorides, and silicates. It is believed that mixing oil with water and surfactant or one of these compounds provides a method for uniformly distributing the surface oxide at the meniscus for casting applications, thereby reducing vertical fold formation that lead to cracks in aluminum ingots. In addition, the mixture promotes uniform heat transfer around the mold allowing the solidifying aluminum alloy to stay in contact with the mold longer and form stronger ingot shells. A process for continuous or semi-continuous casting of aluminum alloys via the use of this lubricant composition is also disclosed.

    摘要: In a lubricant composition suitable for use in the manufacture of aluminum alloys comprising a lubricant base, the improvement wherein the lubricant composition further comprises: an effective amount of water, surfactant, and a high viscosity organic material having a low vapor pressure. It is believed that this mixture provides a method for uniformly distributing the surface oxide at the meniscus for casting applications and increasing meniscus stability. Uniform distribution of the oxide and increased stability at the meniscus reduces vertical fold formation that can lead to cracks in the aluminum ingot. In addition, the mixture promotes uniform heat transfer around the mold. Uniform heat transfer around the mold allows the solidifying aluminum alloy to stay in contact with the mold longer and form stronger ingot shells. A process for continuous or semi-continuous casting of aluminum alloys via the use of this lubricant composition is also disclosed.
