Abstract
The invention relates to a method for guiding billets in a continuous casting facility, in particular a facility for producing thin slab ingots from steel, with an ingot mould and a billet-guiding frame provided with a cooling device. Heat is withdrawn indirectly from the billet as it leaves the ingot mould, the billet at least in sections is held in shape by a gaseous medium, led in the direction of the billet discharge and further cooled. The billet is moved in a defined manner by mechanical means at a predetermined speed through the billet frame, the billet being accelerated or braked on its way. The invention also concerns a device for carrying out the process.
Description
The present invention relates to the method that a kind of continuous casting facility that is used to guide continuous pouring is especially produced the strand of thin band steel equipment, equipment has a fixed crystallizer or a portable crystallizer and a strand guiding frame that is provided with cooling device is arranged, and the invention still further relates to a kind of equipment that is used to implement the method.
Strand guiding in slab or steel bloom continuous casting facility is undertaken by the roller that is located at the crystallizer below usually.If these rollers are non-cooleds, then they have the diameter at least about 100mm, if they have interior cooling, the diameter of the 140mm that then has an appointment at least.In the slab continuous casting facility, the slab width can be taken to 3.5m, and this causes using the split roller of band intermediate support.
When using non-cooled roller, adopt the water spray cooling usually.This class water spray cools off the danger that lies dormant strand is uncontrollably cooled off, and consequently can cause the face crack of strand.
Roller diameter has been determined each roller mutual spacing in conjunction with the strand width.Can be used as this roller spacing of the characteristic parameter of estimating strand supporting or strand protuberance, slab quality is had direct influence.The protuberance of strand depends on the mutual edge distance mutually of poring rate and roller.Be 2.2m/min with maximal rate when the standard slab of cast thickness about 200mm, and employing speed is 6m/min when pouring into a mould the thin slab of the about 50mm of thickness, seeking with speed is 8m/min.
In addition disadvantageously, the casting blank outer cover of thin slab is discharged to it from crystallizer and solidifies, and compares with the casting blank outer cover of standard slab, and temperature is higher significantly in same metallurgical place.
Because the mutual edge distance mutually of the diameter of roller and each roller can not arbitrarily reduce, thus higher and meanwhile pour into a mould under the less situation of thickness in poring rate, the strand protuberance and thereby the tendency of distortion increase in the mode that can't restrain again.
Except that strand guiding roller, the also known plate of using is as the strand guide member.For example advised a kind of grid in EP 0 107 563A1, it is located at crystallizer below and sprays cooling medium by its free cavity towards casting billet surface, for example water spray.
The shortcoming of this member is to produce big frictional force between strand and plate.Have the danger of mass defect in addition, its form is set off an explosion by inclosure for fracture or because of water.Moreover, needing big pullout forces in order to pull out strand, they cause casting blank outer cover to be subjected to high load capacity.
Therefore the objective of the invention is, adopt simple device creation also can be used for the strand guiding of high poring rate, it can be by the high strand of the low wearing and tearing ground production surface quality of device simple in structure.
For achieving the above object, press one aspect of the present invention, a kind of method of strand of the continuous casting facility that is used to guide continuous pouring is provided, equipment has a crystallizer and a strand guiding frame that is provided with cooling device, it is characterized by: extract heat with the strand middle ground that leaves crystallizer; Strand at least the piecewise by a kind of gaseous medium solid shape, be directed in the strand discharger and additional cooling; And strand is additionally made prescribed motion by the speed that can be scheduled to by the strand frame by means of mechanical device, and at this moment, the speed of strand is accelerated or slows down.
For achieving the above object, press another aspect of the present invention, provide a kind of enforcement to be used to produce the continuous casting facility of strand according to said method of the present invention, it has a crystallizer, connect strand guiding frame along the cast direction on crystallizer, the latter has the roller that rests on the casting billet surface and is shaped on the plate in hole, and this equipment is useful on the member of cooling casting billet surface, it is characterized by: the plate section of being divided into, between the roller section of being located at; In the plate section, approach to be provided with on that side of strand the network of distributing pipe, can import gaseous medium by this network; The distributing pipe piecewise is connected to each other and is connected with the station of supplying gas by house steward; And the plate section is arranged to respect to casting billet surface a distance is arranged at least in the marginal zone, and this distance allows certain gaseous medium leak volume.
By the present invention, strand slides on an air cushion after leaving crystallizer, and air cushion is laid between plate section and the strand, and the heat of strand absorbs from strand indirectly by receive the photothermal coldplate of strand contactlessly.Medium as gaseous state preferably uses nitrogen, by layout board section rightly it in the shape of the wall place holding plate section that faces strand, discharge direction along strand and flow, and in order to receive indirect heat (radiant heat) to borrow rib to replenish cooling by coldplate in gas that this flows.
In a kind of arc equipment, strand is by a plurality of bending points or also serially by the identical curved of shape.The merit that the air film of section O and subsequent segments can be done comprises
-according to vertical component and the guiding of the strand between horizontal component place difference, support strand with the component of weight in continuous casting guiding with becoming;
-become ground balance ferrostatic pressure with vertical range with respect to mould inner metal liquid face;
-casting blank bending and orientation;
-molten condition rolling in process of setting, reduce slab thickness;
-conveying strand.
In addition, to need not be the work done of supporting strand (weight) to the upside that should be taken into account strand guide plate section.Moreover, at each section or to export to the strand guiding end from crystallizer inequality along the long measure merit of metallurgy.
The merit that each plate section is different takes advantage of the adjusting device of flow to guarantee by plate section concrete structural design and/or gas medium pressing force.Consider the relation of the current outer casing thickness of strand here especially.When the design of equipment, should note measuring the pneumatic work that acts on the strand,, swell but can uncontrolledly not be out of shape that is bear owing to being pressed into to guarantee the strand slip, carry and to reduce its cast thickness when needed.
Meanwhile, strand is additionally made prescribed motion by the speed that can be scheduled to by the strand frame by means of mechanical device (mainly being the continuous casting roller) here.These rollers can be supported, bear or guarantee to carry and desired poring rate and/or bending and orientation process.In order to guarantee poring rate in accordance with regulations, utilize the roller that is located at continuous casting frame end, here because strand is saturating firmly.
Driving energy by air-flow and continuous casting roller can be coordinated arbitrarily mutually.In a kind of favourable design of the present invention, strand is carried by air-flow, and by the continuous casting roller its speed is reduced to normal speed.
The plate section is made of hollow body basically, and the best drawing-in type of cooling medium ground flows by hollow body.In the plate section, approach to be provided with on that side of strand the network of distributing pipe, import for example nitrogen of a kind of gas by this network.The distributing pipe piecewise is connected to each other, and is connected by house steward and a station of supplying gas.Each spout of distributing pipe can be designed to inequality.Their distribution also can be complementary with it according to the amount of work of its Location in the strand guiding.For example nozzle quantity in section and/or spout overall size become function along metallurgical length with width, so that make different merits in different geometric positions when supplying identical pressure.This for example each pressure system (plate section, pneumatic pillow) when uniform pressure is arranged in order there to be the different nozzle that power carried out to distribute, both can be present in respect to the cast direction laterally also can be present in respect to the cast direction vertically.In addition, a section also can connect with different pneumatic systems independent of each other.
Suggestion in addition, the part of nozzle or nozzle is with respect to the oblique angle of cast direction Cheng Rui, to help the conveying of strand.This support that strand is carried guarantees casting speed and supports and alleviate the right workload of roller that is located between the plate section.The plate section has a distance in the marginal zone with respect to casting billet surface at least, this apart from allow strand and at least between the set lip in marginal zone gas certain leak volume is arranged.
Plate section and actuator for example piston-cylinder assembly link to each other, and can adjust the distance of plate section and strand in accordance with regulations and thereby adjust the gas leakage amount by them.
The wall that approaches strand is designing aspect its structure and material in such a way, that is, make it can farthest discharge radiant heat.Preferably adopt the less copper of wall thickness here, so that absorb this heat by the cooling water that is arranged in the plate section cooling jacket.
In the another kind of design of the present invention, the wall thickness that the plate section approaches the wall of strand be change and also by this way, that is, thickness reduces gradually towards the direction of plate main shaft.In addition, the wall that the plate section faces strand can be coated with wear-resisting protective layer, for example nickel dam and/or chromium layer.
In a kind of design, the plate section is made of pipe, and pipe is arranged to meander-like and inserts the distributing pipe of supply gas at their contact wire place.Adopt this tube-cooled water can high velocity stream to cross and thereby can be from strand a large amount of as far as possible radiant heat that looses.
Be to guarantee strand centering operation, the wall that suggestion plate section approaches strand is designed to recessed along the throughput direction of strand.The concavity of wall can begin at recessed crystallizer place and in first section all sections along strand guiding reduce, it is terminal or be very little concavity or flat surface when saturating to strand is hard for example to be reduced to strand guiding frame.A kind of parallel slab can be produced in this way, or also slab can be produced with desired concave shape when seen in cross-section.
In addition, can be along the wide pneumatic work section of section for example by establishing different bore dia regulations.For example, preferably make less pneumatic work in the central authorities of plate section, so that appropriate strand film effect is arranged in strand central authorities.At the strand edge, that is the seamed edge district, strand has the stable shape more than its central authorities.
In addition, can be when air pressure is identical reduces or increase for the pneumatic work that regularly adds, in other words change the distance of plate section with respect to strand by opening or closing the plate section in tape thickness.The value of this pneumatic work is can be by the plate section given in advance during in the distance at upside or downside place with at given slab thickness.
By equipment of the present invention importantly, strand is carried by conticaster with desired speed pneumatic ground.The motor of continuous casting roller has specified accurately poring rate by the additional guarantee of work, or carries (electric motor mode) or roller to be decelerated to desired specified poring rate with the rotation of generator working method and with slab.If the motor current increase exceeds preestablished limit, then base speed is pneumatically revised.
Adopt the method and apparatus of being advised to reach:
-strand do not swell and thereby indeformable, even if the time up to the high poring rate of 10m/min;
-strand do not need direct water-cooling and thereby as far as possible little energy loss arranged;
-when using inert gas, avoided the strand scaling;
-can be little by little crooked and directed by minimum unit are distortion;
-can its solidificating period gradually molten condition rolling and thereby reduce slab thickness;
-there is not the mechanical component of rotation, the advantage of bringing is
Zero guarantees minimum wear and tear in machines, and
Zero compares the cast reliability that can obtain height with the so-called grid (Grid) of water spray cooling,
The zero mechanicalness restriction that does not have strand to carry for example especially just has this restriction in the particularly thin slab equipment of slab equipment in very wide and quick cast there in the continuous casting guiding frame neutralization of being made up of roller.
