Based on the investigation of the lube base oil, thickener and the preparation condition, an extreme pressure urea grease (named as TGR) was prepared, scaled up and applied in a continuous casting unit.

It is introduced the application information of high performances,long life urea grease and complex calcium sulfonate grease in steel mill form the respects of satisfying reliability of equipments,increasing production efficiency,lowering the cost of production and diminishing impact to environment.

It is introduced the affections of base Stocks,thickeners,additives and manufacture technology to urea grease performances,the urea grease manufactured with silicon oil and synthetic esters possesses excellent high & low temperature properties,and manufactured with aromatics amine has high drop point.

The preparation method and parameter for lithium grease from waste fat and oil are studied.

The tribological properties of lithium grease lubricant which was appended different mass nano-SiO2 particles were investigated by the four-ball friction and wear tester.

Great progress has been made by taking the following technical improvement for the 2500 ton Hydropress: to replace thin oil with lithium grease in its lubricating system; to add four manual grease pumps; to lubricate the four griding parts of the movable beam and the six parts of the column plug sleeves.

The fatty acid mixture in fruits of Malamia Oleifera is used to prepare number 1 and number 2 calcium base grease through three steps which meet with the standard of China.

Production of Calcium Base Grease;
