A pre-lubricated stock sheet and a method and system for making the same are described. The pre-lubricated stock is generally in a coil wound form. The stock sheet can have opposing first and second sheet surfaces joined together by opposing side edges and opposing ends. Typically, the first and second sheet surfaces are substantially smooth and planar, wherein the sheet has 3 mg/foot.sup.2/side to about 200 mg/foot.sup.2/side of a solid lubricant having a melting temperature from about 80 to 212 degrees Fahrenheit. Moreover, the opposing side edges usually are substantially free of the solid lubricant. In some configurations, the stock sheet is an aluminum stock sheet, more particularly an aluminum can stock sheet. Furthermore, the lubricant can be in some configurations a food grade lubricant, that is qualifies a low volatile organic compound under one or more of municipal, state and federal governing authorities.

This disclosure relates generally to metalworking fluids. This disclosure relates more particularly to water-soluble metalworking fluids that include high viscosity polymers, and that can be used in metal cold rolling operations.

A heating device including: a rotating member for heating, an opposing member, which is arranged so as to be opposed to the rotating member, and forms a nip portion together with the rotating member, and a biasing member, which is arranged inside the rotating member, has an opposing surface with respect to an inner peripheral surface of the rotating member, and biases the rotating member to the opposing member. The inner peripheral surface and the opposing surface are brought into contact with each other via a grease composition to form a sliding portion. The grease composition contains a base oil. The base oil contains a fluoropolymer having a specific structure and a perfluoropolyether having a specific kinematic viscosity and a specific evaporation loss and having a specific structure.

With excellent heat retention of molten metal and better productivity/work environment, regardless of low-speed or high-speed, the usable die lubricant for die casting will be provided. An aqueous die lubricant for die casting in which a phyllosilicate mineral is dispersed at a concentration of 0.005 wt % or more and less than 5 wt % and has a particle diameter of 0.1 μm or less during the dispersion.

A metalworking fluid includes a pH buffer system having one or more organic acids and one or more organic amines. The organic acids, which include aromatic carboxylic acids and C.sub.10 or higher aliphatic carboxylic acids, may replace boric acid, such that boric acid may be excluded from the metalworking fluid. The organic acids may include at least one of phthalic acid, isophthalic acid, and terephthalic acid. The one or more organic amines include aliphatic and aromatic amines having an amine value of at least 50 mg KOH/g. A method of using the metalworking fluid includes shaping a metal by contacting the metal surface with a tool while cooling and lubricating at least one of the metal surface or tool with the metalworking fluid.

Method for increasing lubrication in metal working processes by the use of phosphate esters of propoxylated and ethoxylated alcohols.

An industrial fluid additive composition comprises one or more sequestering agents one or more compounds of formula (A): (A) wherein R.sub.1 and R.sub.2 are independently selected from substituted hydrocarbyl moieties containing from 1 to 10 carbon atoms or unsubstituted hydrocarbyl moieties containing from 1 to 10 carbon atoms.

The present invention relates to a method of processing a workpiece comprising contacting a tool and a workpiece to effect a change in the shape of the workpiece, and applying a metalworking fluid to a surface area where the tool and the workpiece are in contact, where the metalworking fluid contains a propoxylate of the formula R—O—(C.sub.3H.sub.6O).sub.n—H, where R is a branched C.sub.6 to C.sub.20 alkyl and n is from 3 to 30. The invention further relates to the metalworking fluid, and to a use of the propoxylate as additive in metalworking fluids.

A complex including an active ingredient, and a surfactant. The active ingredient is one or more less-oil-soluble substances selected from the group consisting of a hardly-oil-soluble substance and an oil-insoluble substance, and the one or more less-oil-soluble substances function as an additive for lubricating oil. A method of making the complex.

Provided is a water-soluble metalworking oil comprising a base oil (A) comprising oil-soluble polyalkylene glycol (A1), wherein a total content of water-soluble polyalkylene glycol and methoxypolyethylene glycol is less than 60% by mass based on the total amount excluding water.
