Abstract
The utility model discloses a continuous casting pull-off-preventing pull rod device, which comprises a supporting plate and a front rod head which is penetrated through and welded with the supporting plate; the front end of the front rod head is welded with a continuous casting head; the continuous casting head is a waste-returning cutting head of a steel rolling mill; and a clamping head clamped with the pull rod is arranged at the rear end of the front rod head. The continuous casting pull-off preventing pull rod device adopts the cutting head for steel rolling waste removal, and has high strength and low cost; through the implementation of the technology, the condition of pull-off does not occur in the casting process; the success rate of continuous casting and casting is ensured, the breakout accident rate is reduced, the stable and smooth production is ensured, the labor intensity is reduced, and the yield is increased.
Description
Technical Field
The utility model relates to a continuous casting pull rod, concretely relates to continuous casting is prevented drawing and is taken off pull rod device belongs to continuous casting pull rod technical field.
Background
A dummy ingot needs to be penetrated before a continuous casting tundish is poured, the head of a dummy ingot rod (hereinafter referred to as a dummy ingot head) penetrates to the lower opening of a crystallizer, and in order to ensure that molten steel is normally wrapped in the crystallizer when the tundish is poured, the lower opening of the crystallizer and the dummy ingot head need to be plugged. In the past, a workshop is plugged by a self-made pull rod and is used as a traction device for steel billets, but the steel is easy to pull out in the using process, so that the steel leakage rate is increased, the production stability is influenced, and the yield is reduced.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems, the utility model provides a continuous casting pull-off prevention pull rod device, which can not be pulled off in the casting process; the success rate of continuous casting and casting is ensured.
The utility model discloses a continuous casting pull-off prevention pull rod device, which comprises a support plate and a front rod head which is penetrated through and welded with the support plate; the front end of the front rod head is welded with a continuous casting head; the continuous casting head is a waste-returning cutting head of a steel rolling mill; the rear end of the front rod head is provided with a chuck clamped with the pull rod; the existing pull rod is modified, a scrap-removed cutting head (the diameter is about 25mm, the length is 200 mm) of a steel rolling mill is used for welding, a supporting plate is welded and installed, and a surfacing welding process is adopted between the supporting plate and the pull rod.
Furthermore, an asbestos pad is fixed on one surface of the supporting plate, which is close to the continuous casting head.
Furthermore, the continuous casting head is welded into a concave structure by a cutting head.
Further, the pull rod and the support plate are fixed through overlaying.
Compared with the prior art, the continuous casting pull-off prevention pull rod device adopts the cutting head for steel rolling waste removal, and has high strength and low cost; through the implementation of the technology, the condition of pull-off does not occur in the casting process; the success rate of continuous casting and casting is ensured, the breakout accident rate is reduced, the stable and smooth production is ensured, the labor intensity is reduced, and the yield is increased.
Drawings
Fig. 1 is a schematic structural diagram of embodiment 1 of the present invention.
Detailed Description
Example 1:
the continuous casting pull-out preventing pull rod device shown in fig. 1 comprises a support plate 1 and a front rod head 2 which penetrates through and is welded with the support plate; the front end of the front rod head 2 is welded with a continuous casting head 3; the continuous casting head 3 is a waste-returning cutting head of a steel mill; the rear end of the front rod head 2 is provided with a clamping head 4 clamped with the pull rod; the existing pull rod is modified, a scrap-removed cutting head (the diameter is about 25mm, the length is 200 mm) of a steel rolling mill is used for welding, a supporting plate is welded and installed, and a surfacing welding process is adopted between the supporting plate and the pull rod.
Wherein, an asbestos pad is fixed on one surface of the supporting plate 1 close to the continuous casting head. The continuous casting head 3 is of a concave structure welded by a cutting head. The pull rod and the support plate 1 are fixed through surfacing.
Before casting, personnel in a main control room wear a dummy bar to a secondary cooling room (a secondary cooling room in the continuous casting production process), the personnel at a continuous casting post clamp the pulling-off prevention device to a dummy bar head, and after the asbestos pad is installed, the personnel continue to wear the dummy bar to a crystallizer opening for subsequent operation and casting.
The above-mentioned embodiment is only the preferred embodiment of the present invention, so all the equivalent changes or modifications made by the structure, features and principles of the present invention are included in the claims of the present invention.
