CN202045351U - Guide device for dummy bar of continuous casting machine - Google Patents

Abstract

The utility model discloses a guide device for dummy bar of continuous casting machine. The guide device comprises a guide sleeve which is provided with an insertion hole on lower end face thereof; the insertion hole is matched with a pull ring which is designed to be inserted into the insertion hole to carry out sleeved connection; the upper end of the guide sleeve is frustum-shaped, and a hanger ring bolt is mounted on the upper end face of the guide sleeve. For the tapered guide sleeve, the guide device can play a good guiding role and is prevented from damages caused by collision with the crystallizer; the guide sleeve is made of a flexible material and connected with the hanger ring on the end portion of the dummy bar, so the guide device can guarantee a good connection effect and is prevented from rotating relative to the dummy bar.

Description

Conticaster dummy bar guider

Technical field

The utility model relates to dummy bar, more particularly, relates to a kind of conticaster dummy bar guider.

Background technology

Crystallizer is the nucleus equipment of conticaster, and the heat exchange by crystallizer is solidified high-temperature molten steel.In use, earlier dummy bar is sent into crystallizer, shutoff is carried out in the crystallizer below, in crystallizer, inject molten steel then, by the heat exchange of crystallizer, the molten steel solidification in the crystallizer becomes strand, and the draw ring that stretches into the crystallizer below also solidifies with molten steel, dummy bar is pulled out dummy bar and strand under the effect of straightening machine together in crystallizer then.

The straightening machine is transported to dummy bar in the crystallizer along backing roll, and molten steel carries out condensation after entering crystallizer, and liquid molten steel crystallizes into solid-state strand, and the straightening machine is pulled out together with solid-state strand dummy bar from crystallizer then.See also shown in Figure 1, because dummy bar 1 whole motion process distance long (from the straightening machine to crystallizer 2), therefore, dummy bar 1 is difficult to enter accurately the inner chamber of crystallizer 2 after the conveying of long distance, in case dummy bar 1 can not accurately enter the inner chamber of crystallizer 2, can cause dummy bar 1 bump crystallizer 2, cause crystallizer 2 to damage, thereby cause a series of productions, product quality accident.Among Fig. 13 is the draw ring 3 of dummy bar end.

At present, can accurately enter the inner chamber of crystallizer in order to ensure dummy bar, usually the operation of taking is the operation that links more than two people, and a people enters in two cold houses relative position of observation dummy bar and crystallizer and sends instruction, and an other people carries out the controlling of transportation of dummy bar.This work pattern needs many people's operations, and is accidents caused easily, and the degree of accuracy that dummy bar enters the inner chamber of crystallizer is difficult for controlled.

The utility model content

At the above-mentioned shortcoming that exists in the prior art, the purpose of this utility model provides a kind of conticaster dummy bar guider, can help the guiding of dummy bar, avoids impaired with crystallizer generation collision.

For achieving the above object, the utility model adopts following technical scheme:

This conticaster dummy bar guider is located at the dummy bar end, and link to each other with draw ring, described guider comprises fairlead, have the jack that is complementary with draw ring on the fairlead lower end surface, insert cover stressed joint mutually in the jack by draw ring, the fairlead upper end is truncated cone-shaped, on the end face of upper end lifting bolt is installed.

The range of taper of described truncated cone-shaped is at 5～15 degree.

Described fairlead upper end end face has installing hole, is installed with screw base in the installing hole, and described lifting bolt is connected with the screw base threaded engagement.

Described fairlead is the rubber-like flexible material.

In technique scheme, conticaster dummy bar guider of the present utility model comprises fairlead, has the jack that is complementary with draw ring on the fairlead lower end surface, inserts cover stressed joint mutually in the jack by draw ring, the fairlead upper end is truncated cone-shaped, on the end face of upper end lifting bolt is installed.Fairlead by the band tapering can play guide effect preferably, avoids impaired with crystallizer generation collision; By the fairlead of flexible material, and link to each other with dummy bar end suspension ring by the jack form, not only can guarantee to connect effect, but also can avoid having enough to meet the need with dummy bar.

Description of drawings

Fig. 1 is the structural representation of the conticaster dummy bar of prior art;

Fig. 2 is the structural representation of conticaster dummy bar of the present utility model and guider thereof;

Fig. 3 is the cutaway view of guider of the present utility model;

Fig. 4 is the cutaway view along A-A line among Fig. 3.

The specific embodiment

Further specify the technical solution of the utility model below in conjunction with drawings and Examples.

See also Fig. 2～shown in Figure 4, conticaster dummy bar guider 4 of the present utility model is located at dummy bar 1 end, and links to each other with draw ring 3.Concrete structure is as follows: described guider 4 comprises fairlead 41, fairlead 41 adopts the rubber-like flexible material to make, the rectangular body in fairlead 41 lower ends, have the jack 42 that is complementary with draw ring 3 on the lower end surface, insert in the jack 42 by draw ring 3, and have the characteristic that clamps insert by fairlead 41 flexible materials, can with draw ring 3 cover stressed joints mutually, and can avoid having enough to meet the need with dummy bar 1.And fairlead 41 upper ends are truncated cone-shaped, the tapering a scope of truncated cone-shaped is at 5～15 degree, such angle design can help the guiding of dummy bar 1, avoid bumping against with the inner chamber of crystallizer 2, even bump against, because fairlead 41 has certain elasticity, also can not cause damage to crystallizer 2 inner chambers.In addition, have installing hole at fairlead 41 upper end end faces, be installed with screw base 43 in the installing hole, screw base 43 screw-internal thread fit are connected with a lifting bolt 44, it plays and dummy bar 1 draw ring 3 same functions, catch on lifting bolt 44 by hook, dummy bar 1 can be taken out from the top of crystallizer 2, finish the whole dummy ingot operation of sending.

Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
