The area is larger, and the effect is better.

In the on-line dust fall guide and guard device of the short stress rolling mill, the angle formed by the dust suppression water hole and the rolled piece entering the guide and guard body is 30-45 degrees.

The beneficial effects of the utility model are as follows:

the utility model adopts the dust suppression water hole, does not adopt the spray nozzle, the spray nozzle has high requirements on water quality and pressure, is easy to block, is inconvenient to use, needs clean water, adopts the water hole to suppress dust, has small pressure requirement, is not easy to block, directly uses the turbid circulating water system in the rolling mill in the prior art to realize water supply, does not need to additionally connect a clean water source, is convenient to use, reduces the use of resources and energy consumption, reduces the cost, is not easy to block, influences the work, and improves the working efficiency.

Compared with the device arranged at the outlet end, the device provided by the utility model is arranged at the inlet end of the guide and guard, can inhibit dust at the first time, and effectively improves the field environment.

Aiming at the problem that dust such as oxidized scrap iron is easy to generate in the rolled piece during on-site rolling, the dust is discharged in a workshop in an unorganized manner, and the environment is influenced. The utility model aims to mainly reduce the unstructured emission of dust during rolling of two-roller rolling mill, inhibit the dust and improve the field ring.
