Abstract
The utility model relates to the field of rolling strip steel surface quality control, in particular to a device capable of overcoming the outlet corrosion defect of a cold rolling integral unit. The device is characterized in that a fan heater, moisture absorption fiber layers and a condensate water drainage groove are included, the fan heater is arranged at the position of an outlet of the integral unit, a heater outlet is formed in a space above a steel plate, the condensate water drainage groove is formed in the bottom of a smoke discharging fan housing, and the condensate water drainage groove is connected with an emulsion collecting tank through a pipeline. The moisture absorption fiber layers are wound on the metal surface of accessory equipment inside the space above the steel plate. Compared with the prior art, the device capable of overcoming the outlet corrosion defect of the cold rolling integral unit has the advantages that the corrosion defect caused by the fact that condensate water on the outlet of the rolling mill integral unit drops onto the steel plate in winter can be overcome obviously, and the rejection rate of the steel plate caused by corrosion is lowered.
Description
Technical field
The utility model relates to the control field of rolled band steel surface quality, relates in particular to a kind of device that reduces cold rolling associating unit outlet corrosion defective.
Background technology
When associating unit milling train exported in the winter time, emulsion steam was condensed into water droplet to steel plate at outlet smoke evacuation fan housing, causes a large amount of corrosions of surface of steel plate, and loss due to spoiled work is 100 tons during November-four months February, brings very big loss to enterprise, is badly in need of solving.
Summary of the invention
The purpose of this utility model provides a kind of device that reduces cold rolling associating unit outlet corrosion defective, and control milling train in winter outlet condensed water produces the corrosion generation of defects, reduces percent defective.
For achieving the above object, the technical solution of the utility model is:
A kind of device that reduces cold rolling associating unit outlet corrosion defective, comprise warm-air drier, water absorbent fiber layer and condensed water drainage trough, warm-air drier is located at associating unit exit, warm braw exports in the steel plate superjacent air space, the condensed water drainage trough is located at the bottom of smoke evacuation fan housing, and the condensed water drainage trough links to each other with the emulsion feeder by pipeline.
Described water absorbent fiber layer is wrapped on the metal surface of the auxiliary device in the steel plate superjacent air space.
Compared with prior art, the beneficial effects of the utility model are: can significantly control winter because milling train associating unit outlet condensing drip drops on the corrosion generation of defects that causes on the steel plate, reduce the steel plate percent defective that causes because of corrosion.
Description of drawings
Fig. 1 is the utility model example structure schematic diagram.
Among the figure: 1-warm-air drier 2-water absorbent fiber layer 3-condensed water drainage trough 4-steel plate 5-emulsion feeder 6-outlet hydraulic cylinder 7-jockey pulley framework 8-smoke evacuation fan housing
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:
See Fig. 1, it is a kind of device example structure schematic diagram that reduces cold rolling associating unit outlet corrosion defective of the utility model, comprise warm-air drier 1, water absorbent fiber layer 2 and condensed water drainage trough 3, warm-air drier 1 is located at associating unit exit, warm braw exports in steel plate 4 superjacent air spaces, condensed water drainage trough 3 is located at the bottom of smoke evacuation fan housing 8, and condensed water drainage trough 3 links to each other with emulsion feeder 5 by pipeline.
Water absorbent fiber layer 2 is wrapped on the metal surface of auxiliary devices such as the interior outlet hydraulic cylinder 6 of steel plate superjacent air space and jockey pulley framework 7, and water absorbent fiber layer 2 can be used calico.
Warm-air drier 1 is steam heating, make steel plate 4 superjacent air space temperature increase to 60～70 ℃ in associating unit exit, reduced condensation vapor, a small amount of condensate water on auxiliary device surface is adsorbed by the water absorbent fiber layer, can not be dropped on the steel plate, thereby stop the steel plate corrosion problem that causes because of condensed water.
Claims (2)
1. one kind is reduced the device that cold rolling associating unit exports the corrosion defective, it is characterized in that, comprise warm-air drier, water absorbent fiber layer and condensed water drainage trough, warm-air drier is located at associating unit exit, warm braw exports in the steel plate superjacent air space, the condensed water drainage trough is located at the bottom of smoke evacuation fan housing, and the condensed water drainage trough links to each other with the emulsion feeder by pipeline.
2. a kind of device that reduces cold rolling associating unit outlet corrosion defective according to claim 1 is characterized in that described water absorbent fiber layer is wrapped on the metal surface of the auxiliary device in the steel plate superjacent air space.
