Description
Technical field
The utility model relates to a kind of milling train de-scaling water nozzle dismounting device, belongs to metallurgy industry steel rolling equipment technical field.
Background technology
Metallurgy industry, in hot-strip production process, for guaranteeing product surface quality, prevent that iron scale is rolled into, before steel billet enters roughing and finish rolling, be equipped with high-pressure water descaling system, with remove heating furnace generate once oxidation iron sheet and roughing to the secondary oxidation iron sheet generating between finish rolling.In high-pressure water descaling system work, due to water under high pressure squeezing action, oxidation of impurities iron extruding in de-scaling water nozzle and water is killed.In the time of system maintenance, de-scaling water nozzle is difficult to take off, and the method that generally adopts shovel limit, limit to knock, wastes time and energy, and very easily dephosphorization water nozzle is caused to mechanical wounding.Due to dismounting difficulty, cause water descaling system difficult in maintenance, de-scaling quality does not guarantee, has influence on product quality.
Utility model content
The utility model object is to provide a kind of milling train de-scaling water nozzle dismounting device, facilitates the dismounting of dephosphorization water nozzle, guarantees that dephosphorization water nozzle is not subject to mechanical wounding, solves the problem existing in background technology.
The technical solution of the utility model is:
A kind of milling train de-scaling water nozzle dismounting device, comprise dephosphorization water nozzle gripping mechanism, nut sleeve, adjusting lever and gravity drop hammer, dephosphorization water nozzle gripping mechanism is connected with adjusting lever by nut sleeve, adjusting lever is provided with gravity drop hammer, gravity drop hammer and adjusting lever are slidably connected, and described dephosphorization water nozzle gripping mechanism is that threaded semi-ring is established in two identical band boss outsides, inside of structure.
Threaded semi-ring is established and is stuck in the groove location of dephosphorization water nozzle in the band boss outside, inside that described two structures are identical.
Adopt the utility model, dephosphorization water nozzle gripping mechanism is stuck in to the groove of dephosphorization water nozzle, make de-scaling water nozzle stressed evenly, mobile gravity drop hammer, by the impact strength of gravity drop hammer, de-scaling water nozzle is taken out from de-scaling ring to the caused mechanical damage of mode of having avoided shovel limit, limit to knock.
The beneficial effects of the utility model are: facilitate the dismounting of dephosphorization water nozzle, guarantee that dephosphorization water nozzle is not subject to mechanical wounding, extend the service life of dephosphorization water nozzle, save dephosphorization system maintenance time, scale removal effect is guaranteed simultaneously, improve high-pressure water descaling system operating efficiency, simple in structure, easy to use.

In figure: dephosphorization water nozzle 1, dephosphorization water nozzle gripping mechanism 2, nut sleeve 3, adjusting lever 4, gravity drop hammer 5.
The specific embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
With reference to accompanying drawing 1,2,3,4,5,6, a kind of milling train de-scaling water nozzle dismounting device, comprise dephosphorization water nozzle gripping mechanism 2, nut sleeve 3, adjusting lever 4 and gravity drop hammer 5, described dephosphorization water nozzle gripping mechanism 2 is that threaded semi-ring is established in two identical band boss outsides, inside of structure, dephosphorization water nozzle gripping mechanism 2 is connected with adjusting lever 4 by nut sleeve 3, adjusting lever 4 is provided with gravity drop hammer 5, gravity drop hammer 5 can horizontally slip on adjusting lever 4, and threaded semi-ring is established and be stuck in the groove location of dephosphorization water nozzle 1 in two identical band boss outsides, inside of structure.
Dephosphorization water nozzle gripping mechanism is stuck in to the groove of dephosphorization water nozzle, mobile gravity drop hammer, by the impact strength of gravity drop hammer, de-scaling water nozzle is taken out from de-scaling ring, simple and convenient, for descaling system adjustment and maintenance facilitates, guarantee de-scaling quality, win the production time, thereby create larger benefit.
Claims (2)
1. a milling train de-scaling water nozzle dismounting device, it is characterized in that comprising dephosphorization water nozzle gripping mechanism (2), nut sleeve (3), adjusting lever (4) and gravity drop hammer (5), dephosphorization water nozzle gripping mechanism (2) is connected with adjusting lever (4) by nut sleeve (3), adjusting lever (4) is provided with gravity drop hammer (5), gravity drop hammer (5) is slidably connected with adjusting lever (4), and described dephosphorization water nozzle gripping mechanism (2) is that threaded semi-ring is established in two identical band boss outsides, inside of structure.
2. milling train de-scaling water nozzle dismounting device according to claim 1, is characterized in that band boss outside, inside that described two structures are identical establishes threaded semi-ring and be stuck in the groove location of dephosphorization water nozzle (1).
