Abstract

The invention discloses a lubricant composition for cold spinning of a zirconium alloy pipe. The lubricant composition uses HVIS650 base oil as base oil and employs a plurality of cooperative additives including an oiliness agent, an anti-oxidant, an extreme pressure agent, an anti-wear agent, a friction improver, an antifoaming agent, an auxiliary agent and a strengthening agent. The lubricant composition provided by the invention has good cooling performance, lubricating performance, cleaning performance, diffusing performance, flowing performance, anti-wear performance, bearing capability, wettability and oil film toughness and is capable of reducing zirconium adhesion degree and friction coefficient, facilitating de-oiling, annealing and alkali-acid pickling and can reduce damage and surface defects caused by adhesion of the surface of the pipe.

Description

technical field [0001] The cold spinning zirconium alloy tube lubricant composition belongs to the field of metal processing lubricants. Background technique [0002] Zirconium, a metallic element, is one of the silvery-white refractory metals with a light gray color. Density 6.49g / cm 3 , melting point 1852±2°C, boiling point 4377°C. It is used in the atomic energy industry and as a corrosion-resistant chemical material under high temperature and high pressure. [0003] Zirconium and its alloys have two notable characteristics in the process of cold spinning: one is that the chemical properties are relatively active, so that in the process of cold spinning, it is easy to react with the surrounding environment to cause pollution and reduce the processing performance; adhesion. Since zirconium and its alloys are very easy to stick to tools and molds, in the process of cold spinning zirconium alloy tubes, effective lubricants and lubrication methods should be selected to co...
