Description

A high-pressure water descaler device to prevent steel plates from warping during rolling

Technical field

The utility model relates to the technical field of high-pressure water descalers, and in particular to a high-pressure water descaler device for preventing the steel plate from warping during the rolling process.

Background technique

Strip steel is a thin steel plate with a narrow width and a long length. The hot rolling mill has higher requirements for the rolling temperature of the strip, so the shorter the length of the main rolling line, the better. The finishing rolling descaling machine is installed between the flying shear and the finishing line. The space between the first rolling mill and the rolling mill is usually very limited during design, so the total length of the descaler cannot be too long.

In order to prevent excess descaling water from remaining on the surface of the strip, the current hot rolling mill finishing descaling machine usually sets a collection tank in front of the upper water collection pipe, and the lower water collection pipe needs to be designed in front of the collection water tank. If the lower water collection pipe Set behind the upper water collection pipe, the overall length of the descaler will be lengthened.

In order to save space, at this stage, the lower water collection pipe is usually set in front of the upper water collection pipe. There are at least the following shortcomings and deficiencies: the lower water collection pipe is set in the front and its nozzle sprays upward. After the strip enters the descaler, it is first subjected to The impact of the high-pressure water sprayed from the nozzle on the lower water collection pipe causes the strip steel head to tilt upward (commonly known as head warping), which in turn causes the strip steel to collide with the upper water collection pipe, causing the steel to get stuck. Steel jamming refers to a fault phenomenon in which a rolled piece is stuck on the rolling line during normal operation and cannot be rolled downstream.
