Abstract
The utility model discloses a modified is dummy ingot pull rod for continuous casting, including the pull rod body, locate the slope rigid coupling apart from pull rod body head 90mm and a slip -off preventive pin, constitute 45 degrees contained angles between slip -off preventive pin and the pull rod body, the slip -off preventive pin free end is 30mm towards pull rod body afterbody, slip -off preventive pin diameter at least, and slip -off preventive pin length is 50mm. Adopt the utility model discloses after improving the dummy ingot pull rod of structure, stop the start basically and drawn the accident of taking off, ensured the production normal clear. The utility model discloses simple structure, the easily production manufacturing, low in cost, the result of use is obvious.
Description
Technical field
This utility model is related to a kind of improved continuous casting dummy ingot pull bar.
Background technology
The dummy bar head of steel plant continuous casting dummy bar is rod-pulling type, also referred to as " guide rod type ".When cast prepares, by storing unit
Dummy bar is sent into into two cold houses with withdrawal straightening machine, and dummy bar head is sent into by mouth under crystallizer by arcuate guide section.Dummy ingot pull bar
Effect is that continuous casting is opened.Open after pouring, high-temperature molten steel is continuously poured onto crystallization
In device, molten steel is coagulated together by dummy ingot pull bar and dummy bar head quickly, dummy bar head pull ingot pull bar, dummy ingot pull bar cast base,
The strand for having been formed green shell is drawn from crystallizer.During by withdrawal straightening machine, take off ingot roller and strand and dummy bar head are disengaged, dummy bar
Into storing unit.Dummy ingot Tiebar structure is welded by the screw-thread steel of Φ 34, if additional cold burden is uneven, and pull bar
It is far, then to be easily melted after pull bar and steel contacts during casting, so that dummy bar is departed from steel billet, occur to draw
De- phenomenon, production are forced to interrupt.
The content of the invention
The purpose of this utility model is to provide a kind of improved continuous casting dummy ingot pull bar, can be effectively prevented and occur drawing
Occur pulling phenomenon between ingot pull bar and strand, it is ensured that production is normally carried out.
The purpose of this utility model is achieved in that a kind of improved continuous casting dummy ingot pull bar, including bar body, away from
Affixed a locking pin is inclined away from bar body head 90mm, structure in angle of 45 degrees, is prevented between locking pin and bar body
Towards bar body afterbody, locking pin diameter is at least 30mm to out of stock free end, and locking pin length is 50mm.
After using the dummy ingot pull bar of this utility model improved structure, start is prevented substantially and has pulled accident, it is ensured that production is just
Often carry out.This utility model simple structure, it is easy to manufacture, cheap, using effect is obvious.
Description of the drawings
This utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is attachment structure schematic diagram of the present utility model.
Specific embodiment
A kind of improved continuous casting dummy ingot pull bar, as shown in figure 1, including bar body 2, apart from 2 head of bar body
Affixed a locking pin 3 is inclined at 90mm, between locking pin 3 and bar body 2 structure in angle of 45 degrees, locking pin free end court
To bar body afterbody 4,3 diameter of locking pin is at least 30mm, and 3 length of locking pin is 50mm.Improved using this utility model and tied
After the dummy ingot pull bar of structure, start is prevented substantially and has pulled accident, the phenomenon for pulling strand 1 had not occurred.
Claims (1)
1. a kind of improved continuous casting dummy ingot pull bar, including bar body, is characterized in that：Incline at bar body head 90mm
Oblique affixed a locking pin, between locking pin and bar body, in angle of 45 degrees, locking pin free end is towards bar body for structure
Afterbody, locking pin diameter are at least 30mm, and locking pin length is 50mm.
