Title:
HOT ROLLING COOLANT FOR ALUMINUM AND METHOD FOR PRODUCING ALUMINUM ROLLED SHEET
Document Type and Number:
Japanese Patent JP2023180646
Kind Code:
A
Abstract:
To provide a hot rolling coolant for aluminum having a high heat transfer coefficient and a method for producing an aluminum rolled sheet using the coolant.SOLUTION: A hot rolling coolant for aluminum comprises an oil-in-water emulsion in which a hot rolling oil for aluminum is dispersed in water. The Na concentration of the coolant is 8 mg/dm3 or more to 80 mg/dm3 or less. The conductivity σ (unit: μS/cm) of the coolant at 25°C and the Na concentration [Na] (unit: mg/dm3) satisfy the relationship of the formula (1). The formula (1) is expressed as 400≤σ-3.25[Na]≤1200.SELECTED DRAWING: Figure 3
