Abstract

DC60 Cold rolling lubricant method by emulsion lubrication, which is defined Features that contain - use of constants (Efficiency of Dispensing) that occurs under the condition of the rolling rate at Specificity, emulsion distribution, emulsion concentration, emulsion temperature, plate-out length, width of rolling material or roller bar length, rolling weight, quality level of Rolling material and the type of lubricant and the thickness of the thin layer of oil while the neat lubrication is performed under the condition of lubrication. Specific to estimate the thickness of the thin layer. Of oil produced by lubrication with emulsion Under specific and control lubrication conditions, one or more of the following are the emulsion dispensing, emulsion concentration, emulsion temperature, and plate-out length to ensure the thickness of the Thin layer Of oil The value matches the thickness of the thin layer. Of the oil as the target Method of supplying lubricant in cold rolling by emulsion lubrication, which is determined Features that contain - use of constants (Efficiency of Dispensing) that occurs under the condition of the rolling rate at Specificity, emulsion distribution, emulsion concentration, emulsion temperature, plate-out length, rolling material width or roller bar length, rolling weight, quality level of Rolling material and the type of lubricant and the thickness of the thin layer of oil while the neat lubrication is performed under the condition of lubrication. Specific to estimate the thickness of the thin layer. Of oil produced by lubrication with emulsion Under specific and control lubrication conditions, one or more of the following are the emulsion dispensing, emulsion concentration, emulsion request temperature, and plate-out length to ensure the thickness of the Thin layer Of oil The value matches the thickness of the thin layer.
