Description
Technical field
The present invention relates to cold-rolled steel and produce apparatus field, particularly a kind of milling train water-cooled air-through-tube device.
Background technology
When some specification product of Rolling production, part pre-finishing mill or whole mm finishing mill unit are not involved in rolling,
Rolled piece is from these frame sky mistakes.For preventing mill rolls case sealing member to be at high temperature ruined, milling train have to
Open collars cooling water conduit is cooled down；Due to the movable sealing structure that milling train casing is special, force them
Also to dally with the mill speed of at least 10% in the case of sky is crossed, to meet seal request, prevent water and oxygen
Changing iron sheet to enter inside roller case and pollute, dallying and opening collars cooling water causes unnecessary electric power, liquid
Pressure and compressed air equal energy source consume；And due to milling train low speed rotation, cause casing movable sealing hydraulic performance decline,
Easily causing milling train to intake, affect the safe and reliable operation of equipment, spare parts consumption increases the most accordingly.
Patent CN2810791Y attempts to provide a kind of and improves forming roll case upthrow oil ring structure, i.e. at upper ring oiler
Go up and seal position between retainer and set up a seal groove, seal groove disposes an O as quiet close
Envelope, it solves the milling train roller case sealing problem when stopping, but is both needed to pull down all upper ring oilers also every time
Installing O, must open collars cooling water when crossing steel, additionally air-through-tube is that indirect roller rest ring cools down water projection
Obtaining cooling, particularly catheter interior up, to cross steel passage cooling effect poor.
Patent CN202290774U attempts to make air-through-tube hollow interlayer structure, and central hollow layer introduces cold
But water, and air-through-tube is internal crosses steel passage to have part cooling water to be entered by the water hole on inner catheter, it is achieved right
Rolled piece and the cooling of catheter body, thus stand motor can be made to shut down when milling train zero load, stop lubrication
Stand, and close milling train cooling water.But because being limited by the height of slinger surface on roller case to rolling center, this
Planting air-through-tube external diameter can not be too big, and internal diameter met steel requirement again, causes inner catheter tube wall relatively thin, adds
Work difficulty is big and service life is short；The most lasting cooling water can cause workpiece front end steel temperature low, blackhead steel drift
Hit collars, cause collars to scrap in advance because of local pit, produce technique and equipment breakdown.
Patent CN202045126U is then taked to arrange by-pass collar, when need not essence in finishing mill transmission side
When milling train participates in rolling, rolled piece passes through by-pass collar, thus reaches to close the purpose of finishing mill system.But this
Scheme need to increase bypass bending guide groove, pinch roll, kink and oil gas lubricating system etc., investment height, takes up an area big,
And easily rolled piece surface is produced scratch, produce extra technology trouble.
