Abstract
The utility model relates to a component for a cast iron horizontal conticaster, particularly to an inner crystallizer for producing hollow section bar for a conticaster. The utility model is characterized in that a graphite core sleeve is sheathed outside an outer cooling pipe; heat-insulating material is filled between the graphitic core sleeve and the outer cooling pipe; both ends of the graphitic core sleeve are respectively fixed on the outer cooling pipe through a pressing nut and a front flange disc; the interior of the outer cooling pipe is provided with a water inlet pipe whose rear end is fixed with a baffle ring; the rear end of the outer cooling pipe is screwed by a cap nut of a plug outside the baffle ring. The outer cooling pipe is also provided with a rear flange which is fixedly connected with a stove body of the conticaster through a screw bolt. The utility model solves the difficult problem that hollow continuous casting section bar can not be produced by the prior art; the component can be arranged on the existing cast iron horizontal conticaster for producing hollow cast iron section bars.
Description
Technical field
The utility model relates to a kind of parts on a kind of cast iron horizontal continuous caster machine, is the interior crystallizer that a kind of continuous casting hollow profile is used specifically.
Background technology
It is pure that the horizontal casting section bar has material, no burning into sand slag inclusion, pore and rarefaction defect, compactness, machinability is good, but, the cast iron horizontal continuous caster technology can only be produced prismatic solid cast section bar at present, therefore has only outer crystallizer on the existing conticaster, and there is not interior crystallizer, and put condition survey over nearly 10 years on market according to the horizontal casting section bar, the parts of user more than 70% all are the center skies, so the user is used for centre bore processing a large amount of man-hours adding the needs in man-hour, material and processing cost are risen significantly, thereby limit the user and adopted this kind new material, simultaneously, because crystallization process is by inwardly cooling gradually of table, so cause inside and outside crystalline structure density variation, the parts that process also have this kind defective.
The utility model content
The purpose of this utility model provides a kind of cast iron horizontal continuous caster machine interior crystallizer, makes it can produce hollow horizontal casting section bar on the conticaster so that be installed in.
The purpose of this utility model is achieved in that a kind of cast iron horizontal continuous caster machine interior crystallizer, it is characterized in that, outer cooling tube is set with the graphite core cover outward, graphite core retainer plate front end is pressed on outer cooling pipe end by clamp nut, graphite core retainer plate endoporus front end is held out against on the boss of cooling tube front portion outside by hold-down ring, be filled with heat-insulating material between graphite core retainer plate and the outer cooling tube, the rear end of graphite core retainer plate is fastening by the forward flange dish, and the forward flange dish is connected with the interior external threading of the forward flange on being fixed on outer cooling tube and is fixed by the forward flange nut; Rear stub is connected with the interior external threading of the rear flange on being fixed on outer cooling tube and is fixed by the rear flange nut; The cooling tube rear end has faucet outside; In the outer cooling tube water inlet pipe is housed, the water inlet pipe rear end is fixed with baffle ring, and baffle ring is outer to be tightened in outer cooling tube rear end by the plug nut.
The purpose of this utility model can also realize like this: go back segmentation on the water inlet pipe and be fixed with spike.
The graphite core retainer plate is connected to form by trapezoidal sealing joint by the merogenesis graphite cannula.
Heat-insulating material is an asbestos material.
Outer cooling tube adopts seamless steel pipe, and water inlet pipe adopts stainless steel tube.
The utlity model has following advantage: solved the technical barrier of producing the hollow continuous cast section bar, for large-scale production hollow continuous cast section bar provides technical equipment, through test, the hollow continuous casting section bar that the horizontal caster of employing interior crystallizer is produced, can shorten machined man-hour significantly, make working (machining) efficiency improve more than 30%, be controlled in the 5mm inside and outside the product allowance simultaneously, reduce waste of material to greatest extent, saved raw material greatly, in addition, because cooling procedure changes, promptly cooled off simultaneously by gradually cold the changing into by appearance and inside of the inside single direction of appearance, the inside and outside uniformity of tissue is organized fine and close more.
Description of drawings
Accompanying drawing is the utility model structural representation
The specific embodiment
The utility model is can only produce the uiform section solid casting at present cast iron horizontal continuous caster machine and can not produce the defective of hollow casting and it is carried out architecture advances and a kind of novel features of designing.It is installed on the existing horizontal caster and uses, thereby produces the hollow continuous cast section bar.
Structure of the present utility model is: the outer cooling tube 5 outer graphite core covers 2 that are set with, graphite core retainer plate 2 front ends are pressed on outer cooling tube 5 terminations by clamp nut 1, graphite core retainer plate 2 endoporus front ends are held out against on the boss of cooling tube 5 front portions outside by hold-down ring 3, be filled with heat-insulating material 4 between graphite core retainer plate 2 and the outer cooling tube 5, the rear end of graphite core retainer plate 2 is fastening by forward flange dish 7, and forward flange dish 7 is threaded with the interior cover 9 of the forward flange on being fixed on outer cooling tube 5 and is fixing by forward flange nut 8; Rear stub 10 is threaded with the interior cover 12 of the rear flange on being fixed on outer cooling tube 5 and is fixing by rear flange nut 11; Cooling tube 5 rear ends have faucet 13 outside; In the outer cooling tube 5 water inlet pipe 6 is housed, water inlet pipe 6 rear ends are fixed with baffle ring 14, are tightened in outer cooling tube 5 rear ends by plug nut 15 outside the baffle ring 14.
Go back sectional on the water inlet pipe 6 and be fixed with spike 16.Graphite core retainer plate 2 can be connected to form by trapezoidal sealing joint by the merogenesis graphite cannula.Heat-insulating material 4 is an asbestos material.Outer cooling tube 5 adopts seamless steel pipe, and water inlet pipe 6 adopts stainless steel tube.
The utility model is through the existing successful Application and made hollow cast iron profile material reach normal productive capacity of experiment repeatedly, and through initial estimate, the hollow continuous cast section bar can shorten machined man-hour significantly, improves work efficiency more than 30%.
