Fire hazards are constantly present in the steel industry with operations involving heavy equipment and liquid or red hot steel, and when mineral oil based hydraulic fluids are being used. However, there are alternatives that can be utilized without jeopardizing the performance or productivity of the steel production line.
Roll lubrication was introduced to the 4-high Steckel mill at Nucor Steel Tuscaloosa Inc. in 2011. It was found that the benefits included a significant extension to roll service life and notable reduction of mill torque. This paper will describe the mechanism of lubrication in the roll system and present the improved rolling parameters of the Steckel mill.
Traditional laboratory lubrication tests often involve neat oils. However, compared to the cold rolling process, high levels of lubricant degradation and wear are often found. To better approach the situation in the field, laboratory lubrication tests were developed for emulsions. In this paper, the viability of these methods is illustrated by a number of field cases.
Forming, threading, and hydrotesting tubular goods require the use of metalworking fluids, which are usually in the form of water-soluble concentrates that contain mineral oil, synthetic oils, polymers, or a mix of all three.
