Description

TECHNICAL FIELD

[0001] The utility model belongs to strip steel oiling equipment technical field, concretely relates to a strip steel oiling device of roll coating method oiling. BACKGROUND

[0002] Strip steel oiling is a key process in cold-rolled strip steel production, mainly used for rust prevention and lubrication to ensure smooth subsequent processing. The oiling method of strip steel oiling usually includes electrostatic oiling, roll coating and spraying.

[0003] Roll coating method is still one of the mainstream processes of strip steel oiling due to its high precision and high stability. In order to prevent oil waste and oil dripping, the roll coating method oiling mode minimizes the oil on the surface of the strip steel under the premise of ensuring sufficient coating. Therefore, the existing roll coating method adjusts the settings of the metering roller and the pressure roller to achieve thin and uniform oil coating. The current roll coating method mostly only sprays one side, and the other side of the strip steel cannot be coated. Even after the strip steel is rolled, the uncoated side will contact the coated side, but the uncoated side of the strip steel will still rust due to the small amount of oil on one side. If complete rust prevention is to be achieved, the amount of oil on one side needs to be increased, but increasing the amount of oil on one side will also lead to oil dripping. Therefore, the demand for double-sided coating still exists.

[0004] In order to achieve double-sided coating, the utility model hopes to provide a strip steel oiling device of roll coating method oiling. UTILITY MODEL CONTENTS
