Crystallizer oil

Abstract

The invention discloses crystallizer oil which comprises the following materials by weight portions: 88 percent to 95 percent of high erucic acid vegetable oil, 1.0 percent to 1.5 percent of phenylformic acid or sodium benzoate, 0.5 percent to 1.5 percent of amide imidazoline, 0.5 percent to 1.5 percent of mahogany sulfonate, 0.5 percent to 1.5 percent of foam depressant, 0.5 percent to 1.5 percent of mannite fatty acid ester, 0.5 percent to 1.5 percent of lubricant, 0.5 percent to 1.5 percent of sodium alkyl benzene sulfonate and 1.0 percent to 1.5 percent of polyacrylate. With the latest prescription, the crystallizer oil has good capability of dissolution and foreign substances absorption and can keep stable service performance after the absorption of occluded foreign substances. The crystallizer oil can absorb and dissolve the occluded foreign substances floating on the steel scoria interface from the liquid steel and improve the purity of continuously cast products and has high flash point. During the throwing, the crystallizer oil can isolate the air and prevent the liquid steel from secondary oxidation, thus guaranteeing the quality of the steel feed. Furthermore, the steel feed is non-poisonous and odorless and does not contain chemicals which can lead to cancers or easily rot and stank.

Description

technical field [0001] The invention relates to a lubricating oil used on metallurgical machinery and equipment, in particular to a lubricating oil used on a crystallizer of a continuous casting machine in steelmaking equipment. Background technique [0002] Mold oil is a special lubricating oil used on the mold of the continuous casting machine in the steelmaking process. Its main functions are lubrication, cooling, rust prevention, improvement of billet quality and production efficiency. In the known technology, the existing lubricating oil is spindle oil, which is a kind of mineral oil lubricating oil, which is generally formed by dehydrating the third-line oil in petroleum as the base material. Minerals emit large smoke and strong pungent odor during the steel casting process, seriously harming the physical and mental health of workers, and have a low flash point, which is prone to cracks and reticulation during the casting process. At present, the crystallizer equipmen...

Problems solved by technology

In the known technology, the existing lubricating oil is spindle oil, which is a kind of mineral oil lubricating oil, which is generally formed by dehydrating the third-line oil in petroleum as the base material. Minerals, the smoke emitted during the steel casting process is large, the pungent smell is strong, which seriously damages the physical and mental health of workers, and the flash point is low, and cracks and reticulation are prone to appear in the casting process

At present, the crystallizer equipment in some steelmaking plants is often shut down for maintenance, resulting in a low qualified rate of products, and workers have headaches, nausea, and red eyes, which virtually increases the production cost and seriously affects the operation quality of the enterprise.
