Description

Technical Field

[0001] The utility model relates to the technical field of metal rolling machinery, in particular to a wet scale breaking, bending and straightening machine used before pickling in a continuous pickling line for steel strips. Background Art

[0002] In the continuous pickling unit, in order to improve the pickling efficiency of the plate and strip, the plate and strip need to be mechanically scaled before pickling, and the descaling and bending straightening machine is the key equipment for mechanical descaling. It can correct the shape of the plate and strip while mechanically descaling, and can also be used to straighten the shape of the plate and strip alone. At this time, the spray device is not put into use.

[0003] At present, the most common type of descaling, bending and straightening machines at home and abroad is dry descaling, bending and straightening machines, which rely on suction and dust removal devices to clean the detached oxide skin, but there are the following disadvantages:

[0004] 1. The dust removal effect of the air suction dust removal device of the dry descaling and bending straightening machine is limited, especially the floating dust is difficult to clean, which seriously affects the production site environment and the health of operators.

[0005] 2. It is easy to cause a large amount of dust to accumulate in the equipment, which is extremely difficult to clean.

[0006] 3. Due to the rolling of oxidized iron scale between the working rollers, the oxidized iron scale adheres to the plate and strip. When the plate and strip enter the exit tension roller or other guide rollers, it is easy to fall off again in the subsequent working section. Summary of the invention

Multiple nozzles 2 are installed on each strip steel surface cleaning spray pipe, and each nozzle 2 is set with a spraying angle. Each strip steel surface cleaning spray pipe is provided with an anti-collision column for preventing the nozzle 2 from being damaged by the strip steel, and a pipe cap 4 is installed at the terminal of each strip steel surface cleaning spray pipe.

[0012] Furthermore, the third spray pipe is installed at the lower part of the frame, and the main pipeline of the third spray pipe is equipped with a manual butterfly valve three, a solenoid valve three, a pipeline and a pipe cap five.

[0015] The front and rear tension rollers of the utility model can provide sufficient tension for the strip steel, and the descaling and bending straightening machine can provide bending amount for the strip steel. Under the joint action of stretching and bending, the strip steel can produce a certain elongation, so that the oxide scale on its surface can peel off and crack. The oxide scale fallen off the surface of the equipment and the strip steel is cleaned by the spray device and discharged into the sedimentation tank with the wastewater discharge device, so as to avoid floating dust from polluting the on-site environment. The protective device can play a role in waterproofing and dustproofing.
