The continuous casting machine has a tubular or plate-like copper mold into which molten metal is poured to form a refractory metal strip such as steel. A plurality of nozzles are arranged at intervals around the casting mold, and spray the cooling liquid to the casting mold. One or more measuring devices are associated with the mold to measure dimensional changes of the mold in a direction perpendicular to its longitudinal axis. A controller is connected to the coolant to adjust the rate of heat removal and thereby adjust the dimensional change of the mold as the molten metal is cast. Also disclosed herein is a method of monitoring and adjusting the amount of dimensional change of a casting mold in a continuous caster for casting molten metal.
Description
The present invention is about the high-temperature metal continuous casting machine, especially the sort ofly cools off mould and the control mould expansion in use and the system of contraction with the injection cooling fluid.
In traditional continuous casting machine, molten metal is admitted to mold and gives fixed shape to be frozen into.When molten metal enters mold, shell and sclerosis have been formed.In many machines, mold is vertical the placement, and when metal tape continued to solidify, it just curved 90 °, also promptly moves as horizontal direction, and it is cut into independently section subsequently.In the occasion of horizontal continuous-casting machine, band is not curved at an angle of 90, just flatly is present in the mold.No matter in the machine of vertical and level, be with the section of being cut into or give fixed length.
2850 typically of the temperature of the steel of fusing are though that the temperature of some specification also has is low to 2600 °F.In general, be cast steel though most here reference example says, the present invention considers the casting of any metal or alloy, as long as their condensing temperature is above 2600 °F.
The mold of formation steel band is comprising liquid steel and its initial cure is being provided, that is, and and the sclerosis of shell.Band in the curing is drawn at the bottom of mould continuously, and its speed is identical with the liquid steel that adds from the top, and productivity ratio is to become the sufficiently rigid time by shell to determine, this moment, the shell of band contained the heart of liquid steel, came out from mould.The cooling of liquid steel is by a water system cooling water flow to be circulated around mold at present nearly all casting machine.Water enters around the bottom of the densification container of mold, and the direction that moves against liquid steel upwards flows.The current of adverse current are found in and are suitable for transmitting heat in the continuous casting machine.This cooling system comprises that one forms an annular space tightly around the spacer of mold, and cooling water flows therein.
Find in the use directly to touch the deposite metal that is cast and when being heated expansion, it can reduce to be in the annular space of cooling water circulation usefulness between mould and the spacer when mold.This has just reduced heat absorption efficiency, makes the further expanded by heating of mold, therefore further reduces the cooling water inflow of annular space and circulation cooling usefulness.This situation continued goes down, and can cause die wall and spacer inner surface to contact in extreme example eventually.When this contact takes place, can cause the fusing of whole mold, but in anything example, cooling effect is reduced sharply, the debase of band.
In order to want to control and keep the relative position of die wall and spacer, continuous casting machine designer on the spacer inner surface, burn-on sometimes little strut or pin.This way is relatively unsuccessful, yet because expand in the zone of mold between strut, this has further increased the distortion of mold.Moreover this mould distortion can cause the rhombus of band profile to heave and other distortion.If mould expand to surpass 0.0755 inch, the stress that produces in mold can surpass the yield strength of mould copper material and cause the permanent deformation of mold, further makes the deterioration of band and damages mold.
Disclose a kind of spraying cooling system in No. the 4th, 494,594, applicant's the United States Patent (USP) that has earlier, it has improved many problems of finding in the said system.Can more effectively cool off mold and its expansion of control than the system of above-mentioned prior art at the spraying cooling system described in this patent.The result is, when using the described spraying cooling system of No. 4,494,594, patent, can obtain high-quality casted steel belt.
Yet, the United States Patent (USP) that has earlier 4 the applicant, 494, no matter be that spacer design or the spraying cooling system that has are not earlier all considered the different expansion area (meniscus of finding in 594 in a continuous repeatedly casting machine, middle part and bottom), and the device that has earlier lack any means with monitor enduringly mold in some zones expansion and regulate cooling rate to maintain within the expansion rate of giving decision earlier.Because traditional mold cooling system can not be controlled the expansion of mold, force to such an extent that the operator or the researcher of continuous casting machine goes to accept the adverse effect that uncontrollable mold dilatation produces on casting structure, and then and the adverse effect that the worker who comes produces in very operating, and thus end product quality.
According to the present invention, a kind of continuous casting machine is provided, one or more parameters of its spraying cooling system are formed and set up keeping required mold profile, and can detect and correct the distortion of mold.
The applicant finds by utilizing certain condition and by improving the condition of work of talking about in the United States Patent (USP) 4,494,594 that other formerly has, the just quality that can correctly control the expansion of mold and then control the band that casts out continuously in the mold.Particularly, the applicant finds by regulating cooling fluid carefully towards the zone that is arranged in a scope, and this scope extends under the liquid level about 2.5 inches for about 2.5 inches from the meniscus top, and this can control the distortion of mold most effectively.Be used for producing in the continuous casting machine of short ingot, slab ingot and other shapes at great majority, this zone is positioned at roughly 2 to 14 inches place below the mould top.In this meniscus region, should extract about 70% heat of molten metal out so that make molten metal begin to solidify fast and uniformly.The applicant has determined that also maximum mould expansion allowance is along approximately being 0.0755 inch perpendicular to the mould y direction, is preferably within 0.0550 inch in the liquid level zone, and this is to fix according to the surface and the lower surface of Cast Strip when casting.It also is tolerable expanding above 0.0755 inch if at middle part and lower area, because can not cause damage to the Cast Strip.If surpass these maximum tolerances, the Cast Strip is taken place: the face checking of vertical and horizontal; The lower surface cracking that the surface is following 0.025 to 1.250 inch; Rhombus is heaved the profile distortion with other; With excessive and depth of chatter mark (from 0.007 to 0.100 inch).In addition, can produce the excessive wear of mold.
In order to go to detect and correct these problems according to the present invention, the applicant the distortion measurement meter near mold outside (cold) surface with expansion of each face in the monitoring casting process.The expansion of any one tested surface of mold is controlled in the selected scope, and this is reached by the heat absorption rate of selectively regulating this face.
In order to obtain the precision control to mold dilatation in casting process, nozzle is being kept following parameters:
A) be chosen to facing to the spray angle of the cooling water nozzle of meniscus region and be no more than 100 °;
B) the nozzle pressure facing to meniscus region is maintained at gauge pressure more than 15 pounds/square inch;
C) covering at the jet graphics of meniscus region is designed to like this, and promptly in the unit are of whole jeting surface, the cover graphics between the adjacent nozzle is uniform;
D) water droplet size in meniscus region is maintained at from 475 microns to 1450 microns.
In other zone, the control of expansion is proposed in the United States Patent (USP) that has earlier 4,494,594 according to the applicant.
Owing to there are much more so heats must sucking-off from the meniscus region of molten metal, the vapour barrier that is caused by the injection water vaporization must be penetrated to obtain fast and cooling uniformly by water droplet.When jet angle surpasses 100 °, the power of water droplet is vowed the surface that need cool off perpendicular to mold, towards the edge of jet graphics, can not penetrate the vapour barrier.Equally, when the hydraulic pressure of nozzle was lower than 15 pounds/square inch of gauge pressures, water droplet can not penetrate the vapour barrier.Moreover because the size impact injection water of water droplet penetrates the ability of vapour barrier and the speed of heat absorption, the acquisition of best operating condition is when water droplet size is within above-mentioned scope.
Most deformation of foundry goods is to occur in the casting machine mold, owing to the mold differential expansion causes by the inhomogeneous contact between ingot metal and the cold die wall.Because work in the above-mentioned parameter and since in casting to the monitoring of die wall distortion, this obtains required mold dilatation situation with regard to making operator or researcher to utilize to increase or reduce the cooling water inflow that is sprayed onto on the mold.The situation of foundry goods and quality are also therefore controlled.For example, can allow its to expand as the some of needs expansion mold another is partly then shunk, or each expansion of the same degree of controlled making partly of mold.
Utilize the present invention, the operator of casting machine can monitor situation about expanding in the overall process of casting, and reacts by contingent situation in the mold, cooling system is done necessary either large or small adjusting, thereby influence the quality of the band in solidifying.Therefore can accomplish on all continuous casting machines, solidification process to be controlled comprehensively, no matter it is to produce short ingot, big ingot, slab ingot, circle or other shapes.Moreover, because the operator can monitor the expansion of mold, therefore contacting of monitoring band and mold, his contacting of control Cast Strip and mold of having the ability now, the high temperature on the stress of mold and copper mold surface, thereby direct wearing and tearing and/or the damage that advantageously influences mold.Because the damage of mold is because the high temperature of cast metal full out occurs in meniscus region, this ability of monitoring mold dilatation and temperature continuously can allow the operator directly and advantageously influence the pattern of mold wearing and tearing.
In casting during slab ingot, mold is to form big cavity between the plate to abandoning by the copper coin angle together.Because in most of occasions, flat plate has bigger cross-sectional area relatively, bigger heat must be removed, and copper mold must bear bigger molten iron static pressure.In the mold system of traditional casting slab ingot, the above-mentioned fact need additionally add back-up system on the back of the body (cold) surface of copper coin.This mechanism that needs to support also can be run into when casting littler (short ingot and/or big ingot) section.Use the present invention, just can make designer and operator significantly reduce back-up system and in mold, cancelling second back-up system under most of occasions simultaneously.
