Described baffle plate is a disk, and baffle plate is provided with centre bore, and the diameter of centre bore is greater than the diameter of dummy ingot hook, is convenient to dummy ingot hook through baffle plate.
Described chill cage is comprised of a plurality of annulus and complex root reinforcement, and a plurality of annulus are equidistant separately, and complex root reinforcement is and equidistantly distributes the inner ring that is welded on annulus, by welding, annulus and reinforcement is connected into an integral body.After reinforcement is welded on annulus, one end of reinforcement is concordant with first annulus of chill cage upper end, and the other end of reinforcement stretches out outside last annulus of chill cage lower end, and extension forms an inclined-plane mating with dummy bar head.
While using continuous casting ingot guide sub-assembly, send dummy bar head to two cold houses, dummy ingot hook lower end and cross bar are packed in the open slot of dummy bar head, then dummy bar head continues to enter into crystallizer copper pipe dummy ingot segment process requirement position, with the gap between asbestos cord plugging dummy bar head and crystallizer copper pipe, place mat ground floor shot on dummy bar head, the surface of ground floor shot forms the inclined-plane mating with dummy bar head.Baffle plate from the elbow of dummy ingot hook upper end through being placed on the ground floor shot layer of dummy bar head, place mat second layer shot on baffle plate again, then chill cage is put into the dummy ingot Qiang center that dummy bar head and crystallizer copper pipe form, chill cage lower end is supported on baffle plate through second layer shot, again the screw-thread steel section of some inserted in chill cage and leave space, to open, watering rear molten steel rapid solidification.
Continuous casting ingot guide sub-assembly is installed to rear beginning casting, opening molten steel while watering is full of rapidly in crystallizer copper pipe, dummy ingot hook, chill cage, screw-thread steel section, ground floor shot layer, second layer shot as coolant in dummy ingot chamber have been accelerated solidifying of molten steel, making molten steel form base head is connected with dummy bar head, under withdrawal straightening machine traction, realize strand and produce continuously.Dummy bar head departs from the cross bar of dummy ingot hook lower end after by withdrawal straightening machine in the open slot from dummy bar head, then cut away the cross bar of dummy ingot hook lower end, from dummy ingot hook, takes off baffle plate for envelope dummy ingot next time.
The utility model compared with prior art has following features:
1, simple in structure, the placement of sub-assembly each several part is by manual operation, convenient and reliable;
2, chill cage is open architecture, opens to water rear molten steel and can be full of in time crystallizer, parcel chill cage, forms fast complete base head, can not scratch copper pipe, sufficient roller and backing roll, and casting success rate is high;
3, baffle plate is flexibly connected with dummy ingot hook, and deingot backboard can take off and reuse;
4,, owing to not using sheet iron cylinder, the usage quantity of reinforcing bar reduces, and has reduced production cost.
Below in conjunction with the drawings and specific embodiments, detailed structure of the present utility model is further described.
