Description
Technical field
The utility model relates to a kind of withdrawal straightening machine pulling-straightening rollers of open type cooling structure, belong to metallurgy industry continuous casting installation for casting technology
Field.
Background technique
After the completion of converter smelting, molten steel pours the steel billet that crystallization is different section by conticaster.Wherein withdrawal straightening machine is
Key equipment before conticaster is cut, pulling-straightening roller is a component of withdrawal straightening machine, since high temperature billet steel directly contacts pulling-straightening roller roll surface,
Therefore, the quality of pulling-straightening roller cooling effect directly affects the service life of pulling-straightening roller and the quality of steel billet.
Currently, pulling-straightening roller internal structure and the type of cooling are all made of the cooling of internal cavity closed type structure closed loop, closed circuit cooling
Water inlet is passed through by entering center transmission shaft hole left end water cavity in the insertion tube for the rotary joint being mounted in center transmission shaft hole
Radial two holes in transmission shaft left end enter after body of roll cavity exchanged heat, and enter transmission shaft by radial two holes of transmission shaft right end
Water cavity on the outside of the rotary joint insertion tube installed in centre bore, and enclosed cooling backwater is realized by rotary joint backwater channel,
Return water is recycled after net ring is cooling.This internal cavity closed type structure type of cooling, in actual use, water channel gap is narrow
Small, cooling velocity of water circulation is slow, while taking away steel billet and roll surface contact high temperature, generates a large amount of water in internal cavity and water channel
Dirt after blocking, cannot reach cooling effect, cause pulling-straightening roller both ends spring bearing locking accident, be forced maintenance down replacement, directly
It connects and shortens the online service life of pulling-straightening roller, many adverse effects are generated to billet quality when serious.
Utility model content
The utility model aim is to provide a kind of withdrawal straightening machine pulling-straightening roller of open type cooling structure, and good cooling results use the longevity
Life length, solves the problems, such as background technique.
The technical solution of the utility model is:
A kind of withdrawal straightening machine pulling-straightening roller of open type cooling structure comprising transmission shaft, the body of roll, rotary joint, spring bearing and is inserted
Enter pipe, the body of roll is welded on transmission shaft, is in integral structure, the both ends of transmission shaft are respectively equipped with spring bearing, transmission shaft and the body of roll
Inside be equipped with a cavity, the cavity inside cavity and the body of roll inside transmission shaft is arranged on transmission shaft by multiple
Hole two is connected to, and the body of roll is equipped with multiple holes one with body of roll connects with the internal cavities, and one end of transmission shaft is equipped with rotary joint, rotation
Connector is equipped with the insertion tube with transmission shaft connects with the internal cavities.
Cavity inside the transmission shaft and the body of roll is cylinder.
Hole one on the body of roll is evenly arranged in the both ends of the body of roll.
Being arranged radially along transmission shaft of hole two on the transmission shaft.
The rotary joint is threadedly coupled with transmission shaft.
Using the utility model, cooling water inlet enters transmission shaft by the insertion tube for the rotary joint being mounted on transmission shaft
Internal cavities, the internal cavities of the body of roll are then entered by radial hole two on transmission shaft, after being exchanged heat, pass through the body of roll two
Hole one on side is flowed out, and cooling water is recycled after being collected net ring cooling.
The beneficial effects of the utility model are: can be avoided cooling water channel blocking, good cooling results improve pulling-straightening roller
Online service life reduces the generation of pulling-straightening roller failure.
