Abstract

The invention provides a lubricant for hot rolling of a zinc and zinc alloy plate strip. According to the lubricant, No.7 industrial white oil is used as the base soil and matched with a plurality of complex additives, including an antiwear agent, an oiliness agent, an oxygen corrosion resisting agent, an antioxidant, an anti-foaming agent, an emulsion inhibitor and a metal deactivator. The lubricant is relatively high in antiwear capacity, adbsorbing capacity, bearing capability and dispersion ability, is able to form an uniform and continuous oil film at a certain thickness between a roller and a rolling part, reduces the friction coefficient during rolling, and also can reduce adhering and coking between the rolling component and the roller, has relatively high performances on lubricating, cooling, cleaning and thermal oxidizing stabilizing, and greatly prevents embrittlement during hot rolling.

Description

technical field [0001] The invention belongs to the field of hot-rolling lubricants for zinc and its alloy plates and strips. Background technique [0002] Zinc is a silvery white slightly bluish metal with a density of 7.14g / cm 3 , with a melting point of 419.5°C. At room temperature, it is brittle; at 100-150°C, it becomes soft; when it exceeds 200°C, it becomes brittle again. The chemical properties of zinc are active, and in the air at room temperature, a thin and dense basic zinc carbonate film is formed on the surface, which can prevent further oxidation. When the temperature reaches 225°C, zinc is violently oxidized. It has an indelible position in battery manufacturing in modern industry and is a very important metal. Zinc is mainly used in iron and steel, metallurgy, machinery, electrical, chemical industry, light industry, military and medicine and other fields. Zinc alloy is an alloy composed of zinc as the base and other elements. Often added alloying eleme...
