The specific embodiment
Referring to Fig. 1, single crystallizer comprises crystallizer and electromagnetic system two parts composition.Wherein, crystallizer partly is made up of gland 1, copper sheathing 2, water jacket 3, graphite cannula 6, crystallizer water inlet 7, cooling water cavity 7a, secondary cooling water delivery port 8 etc.; The effect of crystallizer is that copper liquid is cooled off, and forms ingot casting.Said crystallizer copper sleeve 2 inserts in the water jacket 3, between copper sheathing 2 and water jacket 3, forms cooling water cavity 7a, and crystallizer water inlet 7 is opened in the middle and upper part of water cavity 7a, and each crystallizer is all tangentially offered 1-4 water inlet (2 water inlets shown in the figure).In the bottom of water cavity, between copper sheathing 2 and water jacket 3, be the secondary cooling water apopore 8 between the 3-5mm along circumferentially offering diameter.Gland 1 is installed in the top of copper sheathing 2, and gland 1 relies between hold-down bolt 13 and the copper sheathing 2 and connects, and gland 1 dependence hold-down bolt 14 connects with casting between the platform 11.Electromagnetic system partly is made up of the electromagnetic induction coil of wire 4, contact tube water inlet 4a, contact tube current enter 4b, contact tube delivery port 5 etc.See Fig. 1, Fig. 2.
Offer 2-6 road groove (being shown in Fig. 1 twice groove) in the inboard of the copper sheathing 2 of crystallizer; The electromagnetic induction coil of wire 4 is installed in the groove; Contact tube water inlet 4a inner chamber is a cooling-water duct; Contact tube 4b and 5 is an Ampereconductors, and two ends are connected with the medium-frequency generator power supply, and coil of wire cooling water is an industrial pure water.
The electromagnetic induction coil of wire is embedded in the groove of offering in advance the crystallizer inboard; Can avoid the uneven problem of the existing magnetic of traditional cutting seam type electromagnetic crystallizer; The maskless crystallization forward position that acts directly on copper liquid, the magnetic field that the coil of wire produced, electromagnetic efficiency is high.Because the outside of the electromagnetism coil of wire is whole copper sheathing, can prevent leakage field, simultaneously, copper sheathing makes single electromagnetic crystallizer when casting to the shielding action in magnetic field, the electromagnetic crystallizer that closes on is not produced and disturbs, and has created condition for realizing the multimode casting.
Offer the groove of the pre-buried electromagnetic induction coil of wire in 2-6 road in the inboard of each crystallizer, groove offer the middle and upper part that the position is positioned at crystallizer, residing zone, crystallization forward position.Because during the casting of copper liquid, receive the influence of intensity of cooling, liquid level, casting speed, residing position, crystallization forward position changes often, traditional electromagnetic crystallizer adopts the single line volume, and with the variation in crystallization forward position, its electromagnetic action effect can change.The utility model adopts multiple tracks formula groove; When the crystallization forward position moves up and down, still be in the formed electromagnetic field of multiple tracks groove, can effective broken dendrite, eliminate component segregation, eliminate column crystal; Improve cast sturcture and performance greatly, effectively prevent the ingot casting cracking.Because receive the effect of electromagnetic force, the ingot casting scull has the soft effect that contacts with the crystallizer inwall, can eliminate ingot casting surface drawing crack phenomenon, ingot surface quality significantly improves.
Big specification ingot casting multistation fixture system, the more traditional crystallizer height of the height of its single crystallizer hangs down between the 200-250mm.As far as the direct water-cooling casting, the height of crystallizer is low more, and ingot surface quality is good more.
The primary cooling water of crystallizer is an industrial cycle soft water; Can prevent that calcium, magnesium ion from depositing, adhering at the crystallizer copper sleeve inwall; Guarantee that crystallizer heat transfer boundary condition in whole lifetime is stable; Primary cooling water forms secondary cooling water through delivery port 8 ejections of crystallizer water cavity 7a bottom, is used for the ingot casting scull of pulling out crystallizer is directly carried out the secondary water-cooled but.
Each crystallizer in this system all has independently EM induction system, can single crystallizer be installed on the casting platform a casting time big specification ingot casting of casting; Also can with two independently crystallizer be installed on the casting platform 11, relies on people operation, two big specification ingot castings, 1 times of ingot casting work efficiency raising time are cast in casting simultaneously.See Fig. 2.Can also three and above independently crystallizer be installed on the casting platform 18, rely on people's operation, three and above big specification ingot casting time are cast in casting simultaneously, the ingot casting work efficiency bring up to original 3 times reach more than.See Fig. 2, see Fig. 3.
Two station ingot casting device fixture systems comprise the two station ingot casting 1# of system crystallizers 9, the two station ingot casting 2# of system crystallizers 10, two stations casting platform 11, crystallizer water inlet manifold 12.Two crystallizers 9 and 10 are installed in respectively on the casting platform 11.See Fig. 2.
Three stations and above ingot casting device fixture system comprise the three station ingot casting 1# of system crystallizers 15,1# crystallizer water inlet pipe 15a, the three station ingot casting 2# of system crystallizers 16,2# crystallizer water inlet pipe 16a, the three station ingot casting 3# of system crystallizers 17,3# crystallizer water inlet pipe 17a, three stations casting platform 18, three station system crystallizer water inlet manifolds 19.See Fig. 3.
Crystallizer liner copper sheathing adopts goes up big, following little back taper structure, and the crystallizer back cut diameter is than the big 3-7mm of lower port diameter (ingot casting is big more, and the diameter difference of crystallizer upper and lower opening is big more).The back taper structure of crystallizer is consistent with the linear shrinkage characteristic of ingot solidification; Its effect is: reduce and when eliminating because of ingot solidification; The air gap that between ingot casting and crystallizer inwall, possibly form improves the heat exchange condition between ingot casting scull and the crystallizer inwall, strengthens one time cooling procedure.
This big specification ingot casting multistation fixture system adopts the electromagnetic induction coil of wire is embedded in the groove of offering in advance the crystallizer inboard, can avoid the uneven problem of the existing magnetic of traditional cutting seam type electromagnetic crystallizer, and electromagnetic efficiency is high.Global copper is with magnetic field shielding effect preferably, and electromagnetic crystallizer does not produce the electromagnetic crystallizer that closes on and disturbs when casting, has created condition for realizing the multimode casting.When the crystallization forward position moves up and down, still can effective broken dendrite, eliminate component segregation, eliminate column crystal, improve cast sturcture and performance greatly, effectively prevent the ingot casting cracking.Can eliminate ingot casting surface drawing crack phenomenon, ingot surface quality significantly improves.Under the situation that does not increase operating personnel, can increase substantially casting production efficiency.
