Description

The adaptive directed mechanism of continuous-casting of steel billet machine

Technical field

The utility model relates to the adaptive directed mechanism of a kind of continuous-casting of steel billet machine, is used to make steel the guiding mechanism of industry conticaster secondary cooling zone.

Background technology

At present, the Guiding machine of continuous-casting of steel billet machine is general for the size of casting blank section, and the casting blank section range spans that some conticaster need be produced is bigger, and dummy bar generally is by the strand design of the wideest section.In order to lead to dummy bar, the width of guide section also must adapt to it.Like this, when producing the strand of narrow section, the easy sideslip of strand.

General way is not limited the strand sideslip, will cause like this inhomogeneous cooling of strand is spared, and slab quality is reduced.For head it off generally has two kinds of ways: a kind of is to arrange a radially pressure roller at the intrados of strand, utilizes the wheel rim of pressure roller to lead to strand.Another kind of way is for guiding edger roll peace drives cylinder, makes its guiding variable-width.More than two kinds of ways all have the shortcoming of equipment complexity and operational reliability difference.

Summary of the invention

The purpose of this utility model provides a kind of adaptive directed mechanism simple in structure, and it can adapt to automatically to wide dummy bar and narrow strand guiding, need not additional other power set.

The technical solution of the utility model is: the adaptive directed mechanism of continuous-casting of steel billet machine comprises the guiding edger roll, it is characterized in that being furnished with a pair of guiding edger roll 1 in the both sides of guide section, the rotating shaft 2 of guiding edger roll 1 is fixed on the swing arm 3, swing arm 3 is connected with supporting arm 7 on being installed in frame 9 by axle 5, the link stopper 6 of restriction edger roll pendulum angle is arranged in the correspondence position of supporting arm 7, and back-moving spring 4 is on axle 5.

The adaptive directed mechanism of described continuous-casting of steel billet machine, the pressure roller 8 that also has the carrying roller 10 of the rest dummy bar that a level installs and restriction dummy bar that level is installed to lift in this mechanism.

The adaptive directed mechanism of described continuous-casting of steel billet machine, its guiding edger roll diameter is 80-150mm, and the radius of gyration of swing arm is 20-120mm, and the rotating shaft centre-to-centre spacing of swing arm is 200-500mm, and the corner of swing arm is 80-90 °.

The utility model has the advantages that: device structure is simple, and it can adapt to automatically to wide dummy bar and narrow strand guiding, need not additional other power set, reliable, wide accommodation has improved the quality of continuous casting billet, is adapted at long-term work under the adverse circumstances.

The specific embodiment

The utility model provides a kind of continuous-casting of steel billet machine adaptive directed mechanism, and it can adapt to automatically to wide dummy bar and narrow strand guiding, need not additional other power set.But be characterized in adopting swing type guiding edger roll, the spring automatic reset mechanism.

Fig. 1, Fig. 2 have provided concrete structure of the present utility model.Be furnished with a pair of guiding edger roll 1 in continuous-casting of steel billet machine guide section both sides, the rotating shaft 2 of guiding edger roll 1 is fixed on the swing arm 3, and the axle 5 of swing arm 3 is installed on the supporting arm 7 of frame 9, and swing arm 3 can be around the axis A-A rotation of frame 9.Link stopper 6 is the pendulum angles that are used for limiting edger roll, thereby reaches the maximum of restriction edger roll, the purpose of minimum aperture.Back-moving spring 4 is on axle 5.In addition, the pressure roller 8 that also has the carrying roller 10 of the rest dummy bar that a level installs and restriction dummy bar that level is installed to lift in this mechanism.

Its operating principle is: at ordinary times, because the effect of back-moving spring 4, two guiding edger rolls are in nearest position, and promptly two swing arms all inwardly fall, and its position is subjected to 6 restrictions of inboard link stopper, generally to be the limit perpendicular to the dummy bar direction of motion, as shown in Figure 4.When dummy bar is moved into guide section from bottom to top, dummy ingot shaft 11 can back down the guiding edger roll, make its rotation, behind the dummy head 12 bonding steel billets 13, when dummy bar moves downward when leaving guide section, the guiding edger roll rotates to homing (minimal openings degree) under the twisting force of back-moving spring, and the guiding edger roll is adjacent to steel billet all the time, thereby realizes giving the purpose of dummy bar head 12 and continuous casting billet 13 guiding.

The maximum opening degree of two guiding edger rolls is that two swing arms all are in the direction parallel with the dummy bar direction of motion, as shown in Figure 3.The rotational angle of general two swing arms is 90 °.In this scope, lead the size that edger roll can the self adaptation steel billet.

Embodiment 1: give the width of dummy ingot shaft is 200mm, the width of dummy bar head and strand is the design for continuous casting machine guiding mechanism of 100mm, can design by following parameter: guiding edger roll diameter is 120mm, the radius of gyration of swing arm is 50mm, the rotating shaft centre-to-centre spacing of swing arm is 320mm, and the corner of swing arm is 90 °.Like this, the minimal openings degree when the guiding edger roll resets is exactly 100mm, has just reached maximum opening degree 200mm after swing arm rotates 90 °.

Embodiment 2: give the width of dummy ingot shaft is 400mm, the width of dummy bar head and strand is the design for continuous casting machine guiding mechanism of 150mm, can design by following parameter: guiding edger roll diameter is 120mm, the radius of gyration of swing arm is 125mm, the rotating shaft centre-to-centre spacing of two swing arms is 520mm, and the corner of swing arm is 90 °.Like this, the minimal openings degree when the guiding edger roll resets is exactly 150mm, has just reached maximum opening degree 400mm after swing arm rotates 90 °.

But core of the present utility model is to adopt swing type guiding edger roll and spring automatic reset mechanism.Therefore, but if employing swing type guiding edger roll and spring automatic reset mechanism, no matter how concrete size changes, and all belongs to protection domain of the present utility model.
