Description
Technical field
The present invention relates to the auxiliary equipment of steel industry conticaster, under referring in particular to accident condition, the instrument of during process of accident base, dummy head and dummy bar being separated.
Background technology
Iron and steel metallurgical industry, the mode of high-temperature molten steel solidification forming has die casting (high-temperature molten steel is watered into steel ingot, is processed into steel billet through blooming mill or forging press) and continuous casting (high-temperature molten steel is directly watered into continuous casting steel billet) two kinds of modes, implements continuous casting mode, can recovery rate of iron be improved, reduce production cost.
Crystallizer is the nucleus equipment of conticaster, by the heat exchange of crystallizer, high-temperature molten steel is solidified.In continuous casting Operational preparation, crystallizer seal operation is the key factor affecting continuous casting production direct motion.Crystallizer seals, and is mainly undertaken by dummy head.When continuous casting is produced, steel flows through submersed nozzle and enters crystallizer, first contact above dummy bar head and fill in dummy ingot encapsulant, mainly use spring, nail bits etc. at present, be intended to offset or reduce molten steel to the impact of dummy ingot head, reduce molten steel to splash, dummy bar head and initial molten steel are condensed well, is beneficial to and carries out throwing operation.Molten steel enters in crystallizer, starts to mold oscillation, and initial base shell, under the effect of crystallizer cooling water, starts to move downward gradually, is called as seedling-growing time during this period of time.Technique suggestion seedling-growing time in, Mold completes the formation of initial base shell, and along with dummy bar down.
But in actual production, due to the impact of the factors such as steel grade characteristic, seedling-growing time deficiency, the initial base shell of formation forms bleed-out accident after haveing crystallizer:
Will carry out accident base (when referring to have an accident, the strand under accident condition) emergent management after there is bleed-out accident, traditional way is on accident base, adopt cutting oxygen rifle to cut out cutting position, uses steel wire rope up handling.
Point five steps are needed to carry out in the process of accident base:
The first step: after crystallizer stops cast, hang away crystallizer immediately;
Second step: at accident base two side position, takes cutting gun to cut out wire line shoe position;
3rd step: use cutting oxygen rifle to cut off process to accident base;
4th step: to the accident base up handling of having cut, carry out the process of accident base;
5th step: to the remaining accident base up handling be connected on dummy bar head, carry out the process of accident base;
Cutting reprocessing is carried out to accident base, is because accident base length and dummy bar total length sum, is greater than the length of the normal ejection of crystallizer.
2 large shortcomings are had by this accident base processing mode:
One, during the cutting of accident base, owing to using overhead crane control, balance cannot ensure, the personal safety of therefore cutting personnel causes certain threat, and meanwhile, during due to emergent management, strand temperature reaches more than 800 DEG C, too increases the danger of cutting operation.
Its two, the cutting operation time is longer, affects accident base treatment effeciency
Summary of the invention
For solving the problem, the invention provides a kind of novel dummy bar head accident quick-release arrangement of quick release dummy bar head, technical scheme is as follows.
A kind of novel dummy bar head accident quick-release arrangement, for in the state of accident dummy bar head and dummy bar being separated, comprise torsion bar, it is characterized in that, described novel dummy bar head accident quick-release arrangement also comprises, be arranged in the middle part of described torsion bar, one end is connected with described torsion bar, perpendicular to the sleeve pipe of described torsion bar, be arranged at described cannula tip, rear end is socketed on described inside pipe casing and forms Tool for detaching socket part, the Tool for detaching that described sleeve pipe forms Tool for detaching exposed division is exposed in front end, described Tool for detaching exposed division is the hexagonal bolt head that can coordinate with the connecting bolt of described dummy bar head and dummy bar.
Thus, workman can dismantle dummy bar head on the operating platform that distance dummy bar head is far away.
According to one of the present invention novel dummy bar head accident quick-release arrangement, it is characterized in that, described Tool for detaching socket part is cylindrical.
According to one of the present invention novel dummy bar head accident quick-release arrangement, it is characterized in that, the cross-sectional area of described Tool for detaching socket part is greater than the cross-sectional area of described Tool for detaching exposed division.
According to one of the present invention novel dummy bar head accident quick-release arrangement, it is characterized in that, side, described Tool for detaching socket part is formed with the locating piece that can coordinate with described sleeve pipe.
According to one of the present invention novel dummy bar head accident quick-release arrangement, it is characterized in that, the inwall of described cannula tip is formed with the locating slot that can coordinate with described locating piece.
Thus, can at sleeve pipe inner position Tool for detaching.
According to one of the present invention novel dummy bar head accident quick-release arrangement, it is characterized in that, the tube wall that described sleeve pipe and described Tool for detaching are socketed is formed with bolt hole.
According to one of the present invention novel dummy bar head accident quick-release arrangement, it is characterized in that, described Tool for detaching side adjacent with described bolt hole is formed with the bolt slot communicated with described bolt hole.
According to one of the present invention novel dummy bar head accident quick-release arrangement, it is characterized in that, in described bolt hole and bolt slot, be provided with set bolt.
Thus, bolt can be used to pass the bolt hole of sleeve pipe, fix Tool for detaching by bolt slot.
According to one provided by the invention novel dummy bar head accident quick-release arrangement, bleed-out accident base treatment effeciency can be improved, the shortening accident base processing time.Can labour intensity be reduced, improve cutting operation personnel Personal Safety.
