Cold rolling lubricant for titanium and titanium alloy strips

Abstract

The invention relates to a cold rolling lubricant for titanium and titanium alloy strips. The lubricant uses combination of #32 total loss oil for a system and refined castor oil as basic oil, and is matched with a plurality of composite additives. The lubricant comprises an antiwear agent, an oiliness agent, an antioxidant preservative, an anti-foaming agent, an antirust agent, a clearing agent, a dispersant and the like. The lubricant has cooling, lubricating and cleaning properties, and can be used for reducing the extent of the roller adhered to titanium and reducing damage caused by adhesion on the surfaces of the plate and strip, so that annealing treatment is conveniently performed to obtain required mechanical properties.

Description

technical field [0001] The invention belongs to the field of cold-rolling lubricants for titanium and titanium alloy plates and strips. Background technique [0002] Titanium material has significant anisotropy, high rolling resilience, tensile strength and yield strength increase with increasing processing rate; elongation decreases with increasing processing rate. Cold rolling is rolled with small diameter work rolls. When titanium is cold-rolled, as the pass reduction increases and the rolling speed increases, the surface finish will decrease. This is the thermal sticking phenomenon between the roll and the material, and the tiny wear powder generated at this time adheres to the surface of the roll or material. , making the surface of the plate rough. To completely avoid this, it is very difficult to consider the rolling efficiency. In this regard, it is generally rolled under somewhat hot-stick conditions. Compared with stainless steel of the same size, the reduction ...
