Abstract

The invention discloses a cold rolling lubricating agent for a lead and lead alloy sheet strip. 32# oil for a total-loss system is used as base oil and is matched with various composite additives including an anti-wear agent, an oiliness agent, an antioxidant, a metal deactivator, an anti-forming agent, a non-emulsifying agent, a friction improver and the like. The cold rolling lubricating agent has the effects of lubricating, washing, cooling, reducing the roller and rolled piece bonding phenomenon and reducing the damage caused by sheet strip surface bonding.

Description

technical field [0001] The invention belongs to the field of cold-rolling lubricants for lead and its alloy plates and strips. Background technique [0002] Lead is a bluish, silvery-white heavy metal that is toxic and a malleable main group metal. Melting point 327.502°C, boiling point 1740°C, density 11.3437g / cm 3 , hardness 1.5, soft texture, low tensile strength. Lead is prone to rust - oxidize. Lead is often gray because it is easily oxidized by oxygen in the air into gray-black lead oxide in the air, making its silver-white luster gradually dull. An important use of metallic lead is to make batteries. The deformation resistance of lead alloy is small, and the ingot can be made into plates, strips, pipes, rods and wires by rolling, extrusion and other processes without heating, and no intermediate annealing treatment is required. Due to the low shear and creep strength of lead alloys, under certain load and rolling shear, lead alloys are easily deformed and thinned...
