Abstract
The utility model relates to a dummy bar head connecting piece of a small round billet conticaster, which comprises a top plate, a threaded column, a spring, a bottom plate, asbestos cloth and a nut, wherein a top end of the threaded column is fixedly connected with the top plate; the diameter of the top plate is greater than that of the threaded column; the part, below the top plate, of the threaded column is sleeved with the spring, the asbestos cloth, the bottom plate and the nut in sequence from the top down; the bottom plate and a dummy ingot head are of the same size; the diameter of the asbestos cloth is 60 mm greater than that of the bottom plate; the nut is connected with the dummy ingot head. The dummy bar head connecting piece provided by the utility model has a simple structure; after flowing into a crystallizer, initial molten steel has an impact on cold material stacked on the bottom plate first, and then is further cooled by the spring outside the threaded column; through primary cooling of the crystallizer, the molten steel is solidified fast around the upper part of the threaded column and wraps the top plate tightly to ensure enough cooling strength so as to guarantee that the threaded column and top plate are not melted completely and improve the safety.
Description
Technical field
The utility model belongs to Ferrous Metallurgy continuous casting technology field, particularly a kind of roundlet billet continuous casting machine connector for dummy bar head.
Background technology
Dummy bar is the important part of conticaster, the function of dummy bar is to be driven by the drive unit in dummy ingot storing unit from dummy ingot deposit position, and after operation, withdrawal straightening machine position is arrived in walking, and then is driven by withdrawal straightening machine, through secondary cooling apparatus, and then deliver to crystallizer copper pipe end opening.When casting, the driving force producing with withdrawal straightening machine is drawn strand by dummy bar from crystallizer copper pipe, and steel billet enters withdrawal straightening machine after secondary cooling apparatus spray.When dummy bar exits withdrawal straightening machine, under the effect of the de-ingot roller of withdrawal straightening machine, depart from strand, then enter dummy ingot storing unit, wait for and working next time.Dummy bar comprises dummy bar head, transition segment and dummy ingot shaft three parts.
Connector for dummy bar head is mounted in the structural member at dummy bar head position, in crystallizer, is mixed to form steel billet with initial molten steel, and dummy bar enters it withdrawal straightening machine and completes throwing task from drawing in crystallizer.At present conticaster is the direct cold steel of spreading on dummy bar head, and the steel billet head of formation is directly connected with dummy bar head; Also there is part conticaster to use connector for dummy bar head, but still need to add cold steel to water cold burden as opening, easy impulsive motion while meeting initial molten steel, security is poor.
Summary of the invention
The utility model provides a kind of roundlet billet continuous casting machine connector for dummy bar head simple in structure, easy and simple to handle, safe and reliable, with low cost for solving the technical problem existing in known technology.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is:
A kind of roundlet billet continuous casting machine connector for dummy bar head, comprise top board, threaded post, spring, asbestos cloth, base plate and nut, a top of described threaded post is fixedly connected with top board, the diameter of described top board is greater than the diameter of threaded post, in the threaded post of described top board bottom, be socketed with successively from top to bottom spring, asbestos cloth, base plate and nut, described base plate equates with the size of dummy bar head, and the diameter of described asbestos cloth is than the large 60mm of the diameter of base plate, and described nut is connected with dummy bar head.
Described asbestos cloth top is equipped with skim iron nail bits, the upper reinforcing rod of laying of described iron nail bits.
Described top board and threaded post are replaced by nut and bolt respectively.
The diameter of described threaded post is not less than 30mm.
The total height of described top board and threaded post is less than 100mm.
The thickness of described base plate is 4mm.
Advantage and the good effect that the utlity model has are: the utility model is simple in structure, first initial molten steel impacts the cold burden that base plate is stacked after entering crystallizer, then pass through spring outside threaded post further cooling, and once cooling by crystallizer, liquid molten steel solidifies rapidly around the threaded post of top, by tight top board parcel, to guarantee enough intensities of cooling, ensure that threaded post and top board are not completely melted, and have improved security.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
In Fig. 1,1. top board, 2. spring, 3. asbestos cloth, 4. base plate, 5. nut, 6. threaded post.
Detailed description of the invention:
For further understanding utility model content of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 2, a kind of roundlet billet continuous casting machine connector for dummy bar head, comprise top board 1, threaded post 6, spring 2, asbestos cloth 3, base plate 4 and nut 5, a top of threaded post 6 is fixedly connected with top board 1, the outer cover of threaded post 6 is connected to spring 2, the bottom of spring 2 is provided with the asbestos cloth 3 that penetrates threaded post 6, asbestos cloth 3 lower ends penetrate base plate 4, base plate 4 equates with the size of dummy bar head, base plate 4 thickness are not less than 4mm, the diameter of asbestos cloth 3 is than the large 60mm of the diameter of base plate 4, to ensure and the crystallizer copper seal of tube, in the threaded post 6 of asbestos cloth 3 base plate 4 bottoms, be provided with nut 5, nut 5 is connected with dummy bar head.
Whole connector does not need welding, simple in structure, opens before watering and spills skim iron nail bits asbestos cloth 3 tops pavings, the cold burdens such as surrounding's stacking reinforcing rod of the upper threaded post 6 of iron nail bits and spring 2, to guarantee enough intensities of cooling, ensure that threaded post 6 and top board 1 are not completely melted, and have improved security.
The diameter of threaded post 6 is not less than 30mm.
Can use bolt and nut to replace threaded post 6 and top board 1, spring 2 cold burdens that bolt is used through protection bolt.
Operation principle of the present utility model is: this connector packs into after crystallizer by dummy bar head, and asbestos cloth 3 makes itself and the crystallizer copper seal of tube, to avoid molten steel to spill from dummy ingot head; On asbestos cloth 3, paving is spilt iron nail bits, on iron nail bits, stacks the cold burdens such as reinforcing rod.While starting to cast, first initial molten steel impacts the cold burden that asbestos cloth 3 is stacked after entering crystallizer, molten steel after cold burden cooling and shunting uniform ring around connector, further cooling through the spring 2 outside threaded post 6, and pass through the once cooling of crystallizer, liquid molten steel solidifies rapidly around top threaded post 6, by tight top board 1 parcel, after withdrawal straightening machine starts, dummy bar goes out crystallizer by lower thread post 6 and nut 5 drawing steel billet heads and enters in two cold houses, completes throwing.
Above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit, and those of ordinary skill in the field should be appreciated that still and can modify or part technical characterictic is equal to replacement the detailed description of the invention of utility model; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the technology of the utility model request protection.
