Detailed description of the invention
A kind of big round billet crystallizer plays cast iron cage, comprises outer cage 1, interior cage 2 and dummy ingot hook 3, and interior cage 2 is fixedly welded on two cross bar 1-3 of outer cage 1 inner bottom part, and dummy ingot hook 3 is fixedly welded on the framework 2-1 and the first U-shaped bar 2-2 of interior cage 2 bottoms.On the annulus 1-1 of the first U-shaped bar 2-2 and outer cage 1 one end, be welded with a bracing piece 4, bracing piece 4 is used for strengthening being connected of interior cage 2 and outer cage 1.
Described outer cage 1 is made up of annulus 1-1, vertical rod 1-2 and cross bar 1-3, three annulus 1-1 are welded on respectively vertical rod 1-2 two ends and middle part, six roots of sensation vertical rod 1-2 is evenly distributed on the inner ring of annulus 1-1, and two cross bar 1-3 are welded on respectively the annulus 1-1 inner ring of outer cage 1 one end.
Described interior cage 2 is made up of framework 2-1, the first U-shaped bar 2-2, the second U-shaped bar 2-3, the 3rd U-shaped bar 2-4, the 4th U-shaped bar 2-5, the 5th U-shaped bar 2-6 and base plate 2-7, the second U-shaped bar 2-3, the 3rd U-shaped bar 2-4, the 4th U-shaped bar 2-5 and the 5th U-shaped bar 2-6 are groined type and are welded on framework 2-1, base plate 2-7 is welded on the second U-shaped bar 2-3 and the 3rd U-shaped bar 2-4, the first U-shaped bar 2-2 is parallel with the 3rd U-shaped bar 2-4 with the second U-shaped bar 2-3, and is welded on the end of framework 2-1 one end.
Described dummy ingot hook 3 is made up of three right angle knee 3-1 and a straight-bar 3-2, and three right angle knee 3-1 are uniformly distributed and are welded on straight-bar 3-2.
It is as follows that big round billet crystallizer plays the use procedure of cast iron cage: before conticaster throwing, dummy bar head 6 is sent to the position of crystallizer copper pipe 5 dummy ingot segment process requirements, with the gap between asbestos cord 7 plugging dummy bar heads 6 and crystallizer copper pipe 5, then big round billet crystallizer is played to cast iron cage and put into crystallizer copper pipe 5, the dummy ingot hook 3 that big round billet crystallizer rises on cast iron cage stretches in the dovetail groove of dummy bar head 6, again the screw-thread steel section 8 of some being inserted to big round billet crystallizer rises in cast iron cage, and leave space, finally be sprinkled into the shot of some, inclined-plane and dovetail groove bottom surface at dummy bar head 6 form shot layer 9.
Open and water rear molten steel and be full of rapidly in crystallizer copper pipe 5, in dummy ingot chamber, play cast iron cage, screw-thread steel section 8, shot layer 9 as the big round billet crystallizer of coolant and accelerated solidifying of molten steel, make molten steel form base head and be connected with dummy bar head 6, under withdrawal straightening machine traction, realize strand and produce continuously.Dummy bar head 6 is by after withdrawal straightening machine; deingot device rises from the bottom up; because big round billet crystallizer plays base plate 2-7 and the inclined-plane of 9 pairs of dummy bar head 6 of shot layer and the protective effect of dovetail groove bottom surface on cast iron cage, dovetail groove and base head on dummy bar head 6 are departed from smoothly.
