Abstract
The invention discloses a device and method of an H-shaped parison continuous casting machine online dummy ingot. The device comprises a dummy ingot ejector rod, a protective board, a fixed rod and a dummy bar connected with a casting blank. A limit groove is formed in the end portion, contacted with the casting blank, of the dummy bar. One end of the fixed rod is arranged in the limit groove, and the other end of the fixed rod is fixed on the protective board which is fixed on the dummy bar through the fixed rod. The dummy bar can be separated from the casting blank just by ascending and descending the dummy ingot ejector rod, compared with an original manual cutting and disengaging mode according to which many people and a plurality of cutting guns are used, operation procedures are greatly reduced, and working efficiency is improved. Thus, according to the technical scheme, the device and method of the H-shaped parison continuous casting machine online dummy ingot have the advantages of being simple in structure, simple in procedure, high in efficiency, strong in operability, high in safe reliability and the like.
Description
Technical field
The invention belongs to field of metallurgical equipment, be specifically related to the online deingot device and method of a kind of H parison conticaster.
Background technology
In the continuous casting technology field, adopting the H parison is that raw material is produced the H parison, strand directly can be sent into universal mill, roll into H shaped steel or steel I-beam, cogging in the middle of not needing, can reduce rolling pass, shorten production procedure, minimizing equipment is significantly reducingd the construction costs and production cost, and improving the production capacity of lumber recovery and milling train, H parison conticaster has bigger development space and application prospect widely.
At present, 5 H parison conticasters such as the domestic Ma Gang that has been constructed and put into operation, Laigang, Hebei Jin Xi, Changzhi, Shanxi, the equal introduction of foreign technology of its main frame nucleus equipment comprises dummy bar assembling complete set technology.H parison solidification shrinkage in crystallizer forms the base shell, and bond together with the dummy bar head, under the effect of straightening device, by dummy bar H type strand is pulled out backward, solidifying needs to be separated from the dummy bar head after the strand that finishes goes out the straightening device, in existing H parison conticaster, deingot adopts the online cutting mode of flame manually.Be provided with two to three place's cut points between straightening device and flame cutting machine, after reaching the precalculated position at the bottom of the strand, manually manual cutting gun moved a strand and dummy bar head junction cutting part, cut point strand and dummy bar head cutting in the end breaks away from.There are shortcomings such as deingot complex procedures, inefficiency, environment temperature height, poor stability in this deingot mode, hyperthermia radiation effect at strand, the cutting workman is in extremely abominable work condition environment, cutting operation is inconvenience very, especially for the more conticaster of fluxion, the operation of the casting in centre position stream deingot is very inconvenient especially.
Summary of the invention
In view of this, the purpose of this invention is to provide the online deingot device and method of a kind of H parison conticaster, this device technique scheme advanced person, device structure is succinct, operation is simple, efficient is high, strong operability, safe and reliable.
The objective of the invention is to be achieved through the following technical solutions:
The online deingot device of a kind of H parison conticaster, comprise deingot push rod, protective plate, fixed bar and the dummy bar that is connected with strand, the end that described dummy bar contacts with strand is provided with stopper slot, described fixed bar one end places in the stopper slot, the other end is fixed on the protective plate, and described protective plate is fixed on the dummy bar by fixed bar;
Further, the end face that contacts with strand of described protective plate is provided with the connecting rod that increases the molten steel switching performance;
Further, described fixed bar is U-shaped fixed bar, and described stopper slot is U-shaped open slot;
Further, the side of described U-shaped open slot is provided with and is convenient to the oblique chamfering that fixed bar breaks away from dummy bar;
Further, the oblique chamfering span of described U-shaped open slot side is 2 °～20 °.
The present invention also comprises the method that the online deingot device of a kind of H of utilization parison conticaster carries out deingot: U-shaped fixed bar is put in the U-shaped open slot of dummy bar, utilize U-shaped fixed bar and locking nut protective plate to be fixed on the head of dummy bar, the head of dummy bar is closely contacted with the strand front end, strand front end molten steel solidification, strand front end and connecting rod, the link of locking nut and fixed bar and locking nut fuses into one, when arriving the deingot position, strand starts the deingot push rod, the deingot push rod jack-up dummy bar that makes progress, U-shaped fixed bar breaks away from from the U-shaped open slot of dummy bar, and this moment, dummy bar separated with strand.
The invention has the beneficial effects as follows: the present invention only needs the deingot push rod risen with falling and can realize separating of dummy bar and strand, in contrast to the many numbers of former employing the cutting manually of cutting gun is broken away from mode, greatly reduce operational sequence, increase work efficiency, therefore, the present invention possess skills the scheme advanced person, device structure is succinct, operation is simple, efficient is high, strong operability, the high advantage of security reliability.
Other advantages of the present invention, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being apparent to those skilled in the art to investigating hereinafter, perhaps can obtain instruction from the practice of the present invention.Target of the present invention and other advantages can realize and obtain by following specification.
