Monel alloy plate strip cold rolling lubricant composition

Abstract

The invention discloses a monel alloy plate strip cold rolling lubricant composition. The monel alloy plate strip cold rolling lubricant composition adopts No.15 total loss system oil as base oil which is matched with multiple additives such as an extreme pressure agent, an antiwear agent, an oiliness agent, a friction modifier, an anti-foaming agent, an antioxidant, a metal deactivating agent and a reinforcing agent. The monel alloy plate strip cold rolling lubricant composition has the advantages that the good lubricity, cooling property, wettability, liquidity and anti-rust property are achieved, the strength and thickness of an oil film in a deformation zone are improved, the friction coefficients are decreased, and the oil film strength and thickness properties are kept stable; the adhesivity is high, and the antiwear property, the viscosity-temperature property and the washing property are good; the extreme pressure property is high, and adhesion and wear of cold rolling equipment and rollers are reduced; smaller flow shear stress exists, therefore, the cold rolling surface finish and specification precision of a machined monel alloy plate strip are improved, and oil spots and defects on the surface of the cold rolling plate strip are reduced.

Description

technical field [0001] The invention belongs to the field of metal processing lubricants, in particular to a lubricant composition for cold rolling of Monel alloy plate and strip. Background technique [0002] Monel alloy, also known as copper-nickel alloy, is an alloy based on metal nickel and added with copper, iron, manganese and other elements. It has good corrosion resistance and is silvery white. It is suitable for edge wire materials. Its main products are Monel 500, 401, 404 and Monel R-405, R-500 and other models. Among them, the amount of Monel 400 alloy is the largest. Its structure is a high-strength unidirectional solid solution and single-phase austenite structure. It is a corrosion-resistant alloy with the largest amount, the widest application, and excellent comprehensive performance. The alloy has excellent corrosion resistance in hydrofluoric acid and fluorine gas medium, and also has excellent corrosion resistance to hot concentrated alkali solution. At...
