[0130] Example
[0131] The lubricating oil supply amount is controlled in the fifth stage of the hot finishing mill consisting of seven rolling mills from the first to the seventh. The rolled steel products pass through the first station in order to the seventh station, and are rolled in each station. The rolled steel uses general low-carbon steel, and the steel with a thickness of 32mm on the first entry side is rolled so that the exit side thickness of the seventh stage becomes 2.3mm. As the rolled steel, steel with a plate width of 1820mm to 1940mm is used.
[0132] A header is provided to arrange spray nozzles in the axial direction of the roll, and a gear pump capable of individually setting the supply amount of lubricating oil is connected to each spray nozzle. For sprinklers, such as Figure 5 As shown, the spray nozzle is configured. As the roll, a roll whose profile was measured after roll grinding was used. The lubricating oil has a kinematic viscosity of 230cSt at 4...
