Description
Technical field
The present invention relates to high line production fields, and in particular to a kind of low temperature steel rolling of material extends the operation side of spinning tube lifetime
Method.
Background technique
Industry is at present in order to control production cost, and two kinds of control of element of Mn, V are lower in steel billet, in order to guarantee steel performance,
Bring many spare parts consumptions excessive to Rolling production.Spinneret consumption is exactly one of them.
After the high line of steel rolling mill uses cool controlled rolling technology, according to process specifications laying temperature range restraint in φ 10:
670±20℃；8:750 ± 20 DEG C φ, mutually 930-1000 DEG C of laying temperature of control interval, laying temperature substantially drop than before
It is low, since the reduction steel hardness of laying temperature increases, cause spinneret abrasion loss to increase, steel transportation amount tonnage is φ 10 at present:
3000T；φ 8:2000T, the spinneret lost of life lead to spinneret replacement frequently, and spinneret cost consumption is high, production
Rhythm delays, and leverages normal rhythm of production.
Summary of the invention
The present invention is directed in view of the above-mentioned problems, proposing that a kind of low temperature steel rolling extends the operating method of spinning tube lifetime.
Technical program of the present invention lies in:
A kind of low temperature steel rolling extends the operating method of spinning tube lifetime, and this method is as follows:
Measure the coil diameter of new spinneret, it is ensured that the value range of coil diameter is 1150-1250mm；
Spinneret is cooled down by being atomized cooling device；
Pinch roller overstepping coefficient is adjusted to 1.04-1.05, successively crosses steel, adjustment overstepping coefficient is 1.03 after crossing steel 300,
It is every later cross steel 200 after adjust an overstepping coefficient, overstepping coefficient is adjusted from 1.03 to 1.02 or overstepping coefficient from 1.02
It adjusts to 1.03.
It further include external equipment Laying head, the atomization cooling device is mounted on the channel that Laying head leads to spinning pipe orifice
On, the atomization gas that the atomization cooling device generates enters spinning pipe orifice by channel and cools down to spinneret.
The atomization cooling device uses atomization water pressure itself to add, and " tube fluid flow at high speed generates negative pressure to tube wall
Cause tube wall outer fluid by tube wall aperture suction line " by way of be atomized.
The atomization cooling device is additionally provided with protective cover.
The technical effects of the invention are that:
One aspect of the present invention adjusts the running track for changing steel in spinneret by overstepping coefficient, adjusts coil diameter size, prolongs
Long spinning tube lifetime；On the other hand, water is mixed with air generation fog by the atomization cooling device, improves medium specific heat,
Enhance the cooling effect to spinneret, moisture film improves the service life of spinneret to playing the role of centainly lubricating and protection is walked remote.
Specific embodiment
A kind of low temperature steel rolling extends the operating method of spinning tube lifetime, and this method is as follows:
Measure the coil diameter of new spinneret, it is ensured that the value range of coil diameter is 1150-1250mm；
Spinneret is cooled down by being atomized cooling device；Cooling device is atomized using in application number 201310062026.4
It is atomized cooling device.
Pinch roller overstepping coefficient is adjusted to 1.04-1.05, successively crosses steel, adjustment overstepping coefficient is after crossing steel 300
1.03, overstepping coefficient is adjusted after steel 200 to 1.02, and overstepping coefficient is adjusted after steel 200 to 1.03, after 200
Branch adjusts overstepping coefficient to 1.02, and overstepping coefficient is adjusted after steel 200 to 1.03, is circuited sequentially reciprocal.
The present patent application further includes external equipment Laying head, and the atomization cooling device is mounted on Laying head and leads to spinneret
On the channel of inner hole, it is cold to spinneret progress that the atomization gas that the atomization cooling device generates enters the pipe orifice that spins by channel
But.The atomization cooling device uses atomization water pressure itself to add, and " tube fluid flow at high speed, which generates negative pressure to tube wall, to be caused
Tube wall outer fluid is by tube wall aperture suction line " by way of be atomized.
The moon that is averaged in the prior art consumes spinneret 35-40 root, and 4000 yuan of the every radical valence lattice of spinneret cause production cost mistake
Height, on the one hand causes a large amount of consumption of spinneret, and ton steel cost increases；Great disadvantage is also brought to operating rate and yield simultaneously.
After being implemented by new departure: cost decline, operating rate and yield are also opposite to be promoted.
Although embodiment of the present invention is described above, the invention is not limited to above-mentioned specific implementations
Scheme, above-mentioned specific embodiment are only schematical, directiveness, rather than restrictive.The common skill of this field
Art personnel under the enlightenment of this specification, do not depart from the claims in the present invention it is protected in the range of, can also make very much
The form of kind, these belong to the column of protection of the invention.
