Introduction to the packing sheet steel strip mill rolling lubricant

In the demand for rolling lubrication, sheet mill's generally the least strict operation. According to the lubrication performance increase, which can be easily put these requirements can be divided into the following three categories: 1) Production of the plate thickness of low speed rolling mill; 2) The low speed of a rolling steel sheet mill and; 3) High speed rolling mill rolling thinner specifications products. As in the 6 - Described in section 9, according to the above minimum requirements, pickling oil ( Usually a mineral oil) Can be used as the only lubricants, and other water as coolant roll and strip. Is strict requirements for second level, the acid pickling line of the application of mineral oil can be mixed with oil, fat or can be used in the mill and a lard type of lubricant to mix the so-called & other; Soluble oil & throughout; 。 For the most stringent requirements, is commonly used palm oil or its substitute, a medium application in the form of a stable emulsion. In this case, to ensure the proper lubrication performance, and can be used for circulation and filtering, to keep the pollution of emulsion in a minimum of these less stable emulsion system with mineral oil as base and mixed with some fat additives, make the amount of lubricant is not only for economic ( Every consumption of per ton steel rolling 0. 34 - 0. 68 kg) And, if conflict with pickling oil are in nature, can almost unlimited access to maintain its clean state. If indeed produce pollution, acid washing oil will with iron, and at the end of the gasification iron is separated out. In order to produce clean steel sheet, at the end of the sheet mill can use without lubricant and detergent. This method reduced the steel plate on residual oil film thickness, thus reducing the formed during annealing blotch or remnants. Sheet mill, however, the last frame by the need to adopt the shot blast roll, so the detergent should have enough lubrication performance, in order to reduce the roll produced by shot peening processing of iron powder particles.
