Leakage-free rolling mill workstation shaft seal device

Abstract

The invention discloses a leakage-free rolling mill workstation shaft seal device. The device comprises a rolling mill workstation body, an oil seal device is arranged on the rolling mill workstation body, the oil seal device comprises an oil pan, a framework oil seal, a shaft sleeve with an oil slinger, an O-shaped sealing ring, a sealing lip and a grease nipple, an input shaft is arranged on the rolling mill workstation body, and the shaft sleeve with the oil slinger is arranged on the input shaft through a coupler. The leakage-free rolling mill workstation shaft seal device is reasonable in structural design, simple and easy to operate, good in lubricating and sealing effect, convenient to install, small in overhaul and maintenance workload and free of leakage.

Description

technical field [0001] The invention relates to a shaft sealing device of a non-leakage rolling mill workstation, especially suitable for the continuous casting and rolling copper rod Morgan rolling mill workstation, and belongs to the technical field of mechanical parts design and manufacturing industry. Background technique [0002] At present, 50% of the copper rods in the world are produced by Southwire SCR technology, and the American SOUTHWIRE company has provided more than 110 SCR systems to the world. Only 36 lines have been introduced, and the production capacity of bright copper rods has exceeded 10 million t / a, and some new production lines are also being launched one after another. SCR continuous casting and rolling copper rod technology and machine trains have become the leading method of copper wire billet production. Its main technological process is: feeding hoist→shaft furnace→upper chute→slag box→rotary holding furnace→lower chute→tundish→five-wheel steel s...

AI Technical Summary

Problems solved by technology

Although the technology of Morgan’s rolling mill workstation is currently the world’s leading technology, the last few high-speed workstations of SCR Morgan’s rolling mill have problems such as complex structural design, easy leakage, inconvenient maintenance, expensive imported spare parts, and long procurement time, resulting in high fuel consumption, pollution of the site environment, and low cost. High energy consumption seriously affects the corporate image and becomes the production technology "bottleneck" of the production line

Moreover, at present, there is no precedent for improving the shaft seal device or localization of the SCR Morgan rolling mill workstation at home and abroad. Especially with the rapid development of copper processing technology towards high efficiency, energy saving, environmental protection, automation and continuous direction, it is necessary to study a new, It is imperative to localize the shaft seal device of the non-leakage rolling mill workstation
