Dust removing device of high-speed wire and rod rolling machine

Abstract

The invention discloses a dust removing device of a high-speed wire and rod rolling machine. The dust removing device comprises a water spraying pipe mounted at the guide at the outlet of the rollingmachine and communicating with the high-pressure water source, a spraying opening in the water spraying pipe is aligned with the rolling piece deformation area between an upper rolling roller and a lower rolling roller, and the fact that the water spraying pipe can cover and flush a rolling piece deforming in the rolling piece deformation area with water during working is ensured. The dust removing device has the advantages that by covering and flushing the rolling piece deforming in the rolling piece deformation area with the water, secondary iron oxide powder can be effectively removed before the secondary iron oxide powder falls off from the surface of the rolling piece to form dust to prevent the secondary iron oxide powder from drifting into the air to form the dust, the dust removingeffect is greatly improved, the field condition is effectively improved, the on-site electrical equipment is protected, the input costs are low, the operation is easy, and the follow-up maintenance is simple.

Description

technical field [0001] The invention relates to the technical field of dust removal for high-speed wire and bar rolling, in particular to a dust removal device for high-speed wire and bar rolling mills. Background technique [0002] The high-speed wire bar rolling mill completes the rolling and forming of the rolled piece through the roll group composed of the upper roll and the lower roll. The area between the upper roll and the lower roll is the deformation area of ​​the rolled piece. The finished rolled piece is stably exported to the rolling mill exit guide of the roll group. In steel rolling production, the iron oxide scale generated during the heating process of the steel billet in the heating furnace becomes the primary oxide scale, which is flake-shaped, thick, and lumpy when peeled off, which will not cause dust pollution. During the rolling process of the rolled piece by the high-speed wire and bar rolling mill, the iron oxide scale formed by the cooling and defor...

AI Technical Summary

Problems solved by technology

The secondary oxide scale generated by rolling the rolled piece through the roll group is easy to fall off with the vibration of the rolled piece after being output to the deformation area of ​​the rolled piece, thus forming fine secondary oxide scale dust and floating in the workshop. Once the secondary oxide scale dust is scattered in the It is difficult to take effective measures to remove it in the air, resulting in serious dust pollution, which will not only affect the normal operation of the electrical equipment in the workshop, but also have an irreversible impact on the health of the on-site workers due to harsh working conditions
