Abstract

The invention provides a lubricating treatment fluid for stainless steel subjected to oxalate treatment, relating to the technical field of lubricating treatment fluids. The lubricating treatment fluid is composed of oxalic acid, ammonium molybdate, sodium bifluoride, water, sodium sulfite, iron trisulfate and sodium bisulfate. When the treatment fluid is in use, the treatment temperature is kept at 90-95 DEG C, and the treatment time can not exceed 20 minutes and is preferably controlled within 15-20 minutes. The lubricating treatment fluid has obvious lubricating effect, can effectively enhance the yield and production efficiency of the product, and has more obvious effect on the stainless steel product subjected to oxalate treatment.

Description

Technical field: [0001] The invention relates to the technical field of lubricating treatment liquids, in particular to a lubricating treatment liquid suitable for stainless steel after oxalate treatment. Background technique: [0002] Cold extrusion technology is widely used as a method of producing chip-free or less-chip parts and products, and with the development of technology, this technology has been expanded to the production of many low-alloy steels, stainless steels, copper alloys, and low-plastic duralumin. middle. Compared with hot extrusion, cold extrusion has a lower temperature, even under continuous working conditions, it is beneficial for deformation heat effect and process lubrication. However, it is necessary to make much extrusion force in the die at room temperature, the unit pressure can generally reach 2000-2500MPa, or even greater, and the duration of this high pressure is also longer. Due to the cold extrusion, the deformed metal will produce a stro...
