Description
Technical field:
The utility model belongs to the non-ferrous metal manufacture field, relates to a kind of crystallizer that copper and copper alloy billet are used of casting.
Technical background:
The quality of crystallizer is very important in the ingot casting casting process.High-quality, high-quality ingot casting product all has confidential relation with crystallizer rational in infrastructure, that the dress condition is good.The round crystallizer that is used for billet casting at present has following defective: 1., the copper sheathing unreasonable structure, self intensity is lower, and copper sheathing distortion in very easily causing and cause interior copper sheathing to be scrapped and higher length of mould can not be provided is unfavorable for copper liquid gas purging.2, inner water route is unreasonable, easily produces turbulent flow, causes cooling effect not good.3. water-out manners is unreasonable, existing mode is the gap location water outlet of interior copper sheathing and shell junction, caused by factors slits such as burn into collides with variation appears in the meeting of interior in use for some time copper sheathing and shell junction makes water outlet place cooperation not tight, cause copper sheathing and shell to misalign influencing water outlet inhomogeneous, make the ingot casting inhomogeneous cooling even, cause thermal stress remnants.4. the crystallizer flange is yielding, because of the crystallizer flange design unreasonable, mainly show the weak insufficient strength in flange and crystallizer supporting plate contact position, cause flange yielding, give the crystallizer level of adjusting thus, reach when adjusting crystallizer and bracket three centerings and bring difficulty, bring destabilizing factor to control of product quality.5. lifting is provided with, because the copper sheathing own wt is heavy, a people can't independent operation, and labor strength is big, is unfavorable for safety operation.
Summary of the invention:
The technical problem that the utility model mainly solves provides a kind of: 1.) the copper sheathing outer wall is provided with reinforcement, improve self intensity, prolonged service life, and to make effective cooling length be 1.5～2.0 times of general crystallizer, delay the time condensation time, help being beneficial to copper liquid gas purging, improved ingot quality; 2) according to orderly water conservancy diversion thinking, reinforcement is a double end flat-head type screw-like, and the directionality of cooling water and intensity of cooling are improved; 3) independent outlet system is set on the copper sheathing body, avoids causing the uneven problem of water outlet owing to other reason causes to misalign; 4) changed the way of contact of flange and casting supporting plate, increased the thickness of flange simultaneously, flange has improved the flange non-deformability by the original step-like present whole ring-type steel plate type of changing into; 5.) set up the lifting suspension ring, reduce labor intensity, raise labour efficiency, can further avoid the copper sheathing bump injury, also reduced the novel casting copper and the copper alloy billet crystallizer of potential safety hazard simultaneously.
Above-mentioned purpose is achieved in that it comprises: copper sheathing 4 end faces of band platform are provided with tapped suspension ring hole, suspension ring 3 are set in the hole, carrying is provided with the flange 5 of several through holes above the copper sheathing platform, by suspension ring 3 with copper sheathing 4 and flange 5 be arranged at have annular platform and with the shell 7 of flange 5 same positions and size through hole in, oblique hole for water spraying 8 of copper sheathing 4 band shapes and outer end are that the lower surface of ring-type sloping platform is carried on the ring-type lower end table top that has filling sealer 6 on annular recess and the groove in the shell 7, be carried on below the annular platform of copper sheathing 4 on the annular platform end face of shell 7, wherein shell 7 platform end faces are provided with annular recess, in order to fill sealer 6, flange 5 closely is connected with shell 7 with copper sheathing 4 with nut 2 by bolt 1, shell 7 ring-shaped platforms are provided with tapped inlet opening 9 around the below, be together to form the round space of cylindric and middle formation cavity 10, the fourplatemold of the gap location water outlet of copper sheathing and shell junction is adopted in cooling; Unlike the prior art be: copper sheathing 4 inside and outside walls are dimensioned to the concentrically ringed column through hole cavity that an end has annular platform on demand, be processed with groove between the platform on copper sheathing 4 outer walls and the lower surface of the other end, be processed into the bull flat-head type screw-like reinforcement of projection between two grooves, reinforcement is risen size and is cooperated the processing of shell fitted position, high size can be decided according to cavity size at its end, guarantee certain thickness, the inside cavity direction in copper sheathing 4 lower surfaces is provided with the back draught platform of certain width, ring is provided with some oblique hole for water sprayings 8 week on the table top, and the cooling water that circulates in the gap that forms between the outer wall that is used for copper sheathing 4 band reinforcements and shell 7 inwalls sprays to the billet base of casting.
Beneficial effect:
1) improve the copper sheathing structure, by cover spiral bar in increasing, improved copper sheathing self rigidity, optimized crystallizer and effectively cooled off length, the life-span of crystallizer is improved, ingot quality is improved.
2) improve the internal water line structure, the directionality and the speed of the inner cooling water of crystallizer are improved, strengthened cooling effect.
3) change water-out manners, eradicate because the slit of shell and interior copper sheathing junction changes and cause the inclined to one side problem of water outlet, avoided the crooked and distortion of the even thermal stress that causes of ingot casting inhomogeneous cooling.
4) improve flange arrangement, improve strength of flange, further the stationarity of stable crystalline device in casting process.
5) set up the lifting suspension ring, raise labour efficiency, be convenient to the maintenance of crystallizer, reduce maintenance cost.
