Multi-roll oil removal machine with built-in blowing and suction devices and strip oil removal method

Abstract

The invention provides a multi-roll oil removal machine with built-in blowing and suction devices. The multi-roll oil removal machine comprises a rack, a plurality of oil removal rolls, blowing devices and a suction device, wherein the oil removal rolls are arranged in the rack and are arranged above and below a strip respectively; the blowing devices are arranged between upper oil removal rolls as well as between lower oil removal rolls; the upper and lower oil removal rolls are contacted with the strip to form a closed cavity which is defined by the strip, the oil removal rolls, the blowing devices and the rack; the blowing devices are communicated with the closed cavity; the suction device is communicated with the closed cavity through a passage. The noise and the pollution can be reduced and the technological lubricating oil can be saved during work. The invention also provides a strip oil removal method. The closed cavity is formed by making the upper and lower oil removal rolls in contact with the strip ; the blowing devices are arranged in the closed cavity to blow liquid remained on the surface of the strip through high-pressure low-flow compressed air to form fog; the suction device is used for sucking the fog from the two ends of the closed cavity in the axial direction of the oil removal rolls in a low-pressure high-flow mode to achieve an oil removal purpose.

Description

technical field [0001] The invention relates to a degreasing machine and a degreasing method, in particular to a multi-roll degreasing machine with built-in purge and suction devices and a strip degreasing method, belonging to the field of metal material processing machinery and methods. Background technique [0002] During the processing of metal materials, due to the needs of the rolling process, a large amount of process lubricants, such as rolling oil, water, emulsion, etc., should be sprayed on the metal surface. After rolling, some process lubricants will adhere to the surface of the metal strip. If it is involved in the coiler, it is easy to cause slippage or misalignment, which will affect production, increase the difficulty of annealing the strip, affect the surface quality of the finished strip, and increase the consumption of process lubricating fluid. Finally, set up cleaning equipment to remove residual process lubricants on the metal surface. At present, the c...

Problems solved by technology

[0002] During the processing of metal materials, due to the needs of the rolling process, a large amount of process lubricants, such as rolling oil, water, emulsion, etc., should be sprayed on the metal surface. After rolling, a part of the process lubricants will adhere to the surface of the metal strip. If it is involved in the coiler, it is easy to cause slippage or misalignment, which will affect production, increase the difficulty of annealing the strip, and affect the surface quality of the finished strip. At the same time, it will increase the consumption of process lubricating fluid. Finally, set up cleaning equipment to remove the residual process lubricant on the metal surface

At present, the commonly used degreasing devices include roller degreasing, vacuum roller degreasing, belt degreasing, air blowing, cloth clip degreasing, etc. These degreasing devices are respectively suitable for different cold-rolled strips Degreasing, each has its own characteristics, but there are still roller degreasing and vacuum roller degreasing effects that are not good, traditional compressed air blowing noise is loud and pollutes the surrounding environment and affects the health of operators. Cloth clamp degreasing can only be used in Disadvantages such as use at low speed
