Abstract

The invention discloses crystallizer copper pipe drawing oil containing sulfurization modified illegal cooking oil. The crystallizer copper pipe drawing oil comprises the following components in partsby weight: 30-70 parts of the sulfurization modified illegal cooking oil, 20-40 parts of base oil, 0.1-0.5 part of a metal deactivator, 0.1-0.5 part of an antioxidant and 1-7 parts of a tackifier, wherein the base oil is isoparaffin solvent oil and / or polyisobutene with the molecular weight of 500-1000. The sulfurization illegal cooking oil prepared by the invention can play a role of an extreme-pressure anti-wear agent, also has a very good lubricating effect, can reduce the use amount of base oil on the premise of ensuring good use performance of crystallizer copper pipe drawing oil, and greatly reduces the use cost. According to the invention, the application of the illegal cooking oil in the aspect of drawing oil is realized, a better solution is provided for illegal cooking oil treatment, and the environmental stress is relieved.

Description

technical field [0001] The invention belongs to the technical field of crystallizer copper tube forming processing, and relates to a drawing oil used in crystallizer copper tube forming processing, in particular to a crystallizer copper tube drawing oil containing vulcanized modified waste oil. Background technique [0002] The crystallizer is a continuous casting equipment that accepts the molten steel injected from the tundish and solidifies it into a solid slab shell according to the specified cross-sectional shape. The copper tube of the mold is the heart of the continuous casting machine and is an important part of the mold. The steel billet is drawn out after cooling and forming. In order to solve the problem that the copper tube sometimes contacts and separates from the cooled billet shell during the working process, the copper tube of the crystallizer is mostly square or rectangular with one side bent, and the inner cavity of the copper tube is from the upper opening ...
