Abstract
The invention provides a tundish flow control quick change mechanism for a large-sized crystallizer. The mechanism comprises a chassis with an upper sliding plate, an intermediate sliding plate and a lower sliding plate; a sliding plate opening is formed on each sliding plate; the positions of the sliding plate openings of the upper and the lower sliding plates are fixed correspondingly, and the intermediate sliding plate moves left and right relative to the upper and the lower sliding plates; the left and the right ends of the chassis are respectively connected with a hydraulic cylinder; and the hydraulic shafts of the hydraulic cylinders are respectively connected with the left and the right ends of the intermediate sliding plate. In the invention, the intermediate sliding plate is added, and the hydraulic cylinders are arranged on both the sides of the intermediate sliding plate, so that the effect of bidirectional control of the flow rate and the speed of molten steel can be reached, and the service life of the mechanism can be prolonged; and moreover, as a water gap quick change device is arranged at the front end of the mechanism, scrap and replacement of the overall tundish mechanism after corroding the water gap can be avoided, and the continuous casting efficiency can be indirectly improved. In addition, the mechanism has great practicality during casting.
Description
Technical field
The present invention relates to a kind of tundish control stream quick-changing mechanism, relate in particular to a kind of tundish control stream quick-changing mechanism of the large scale crystallizer of casting.
Background technology
In continuous casting, the large scale crystallizer is arranged at the below of tundish, and the tundish mechanism that is provided with through bottom, tundish bottom surface brings molten steel into crystallizer.This tundish mechanism is provided with submersed nozzle.This mouth of a river is arranged in the tundish, and long-term use is etched easily, and; Owing to two slide plates are up and down arranged in the existing tundish mechanism usually, in casting cycle, control the flow of molten steel through the slip of lower skateboard; So common meeting is owing to lower skateboard moves; The pouring channel that makes the mouth of a river up and down form is difficult for centering, causes the error of casting, and the outer of molten steel spatters.
Summary of the invention
The objective of the invention is to solve above-mentioned technical problem, a kind of large scale crystallizer tundish control stream quick-changing mechanism is provided.
The object of the invention is realized through following technical scheme:
Large scale crystallizer tundish control stream quick-changing mechanism; The chassis that comprises following three slide plates in having; Offer the slide plate mouth on the slide plate, the slide plate mouth position correspondence of said up and down slide plate is fixed, said in the middle of slide plate with respect to slide plate move left and right up and down; Said chassis right ends is connected with a hydraulic cylinder respectively, the right ends of slide plate in the middle of the hydraulic axis of hydraulic cylinder connects respectively.
Further; Above-described large scale crystallizer tundish control stream quick-changing mechanism; Wherein the front end on the chassis also is provided with a fast sprue-replacing cylinder; The cylinder axis of said fast sprue-replacing cylinder connects a quick change injection block, and said quick change injection block inboard is provided with the release groove, is placed with a subsequent use mouth of a river in the said release groove.
Beneficial effect of the present invention is mainly reflected in: increased middle slide plate; And the both sides at middle slide plate all are provided with hydraulic cylinder, reach the effect of two-way control molten steel flow and speed, longer service life; And the front end in mechanism is provided with the nozzle quick-change device; Removed the mouth of a river from and corroded scrapping of back whole tundish mechanism and changes, indirect raising the efficient of continuous casting, this mechanism has very big practicality when casting.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Fig. 1: the tundish control stream quick-changing mechanism assembly structure sketch map of large scale crystallizer of the present invention.
Fig. 2: the present invention is the A-A cross-sectional view in use.
Wherein:
The mouth of a river under 13 immersions of 11 tundish openings, 12 mouths of a river
31 fast sprue-replacing cylinders, 311 cylinder holders, 312 steady pins
32 hydraulic cylinder bases, 4 chassis, 5 quick change injection blocks
6 nuts 51 are released groove
The specific embodiment
The present invention has disclosed large scale crystallizer tundish control stream quick-changing mechanism, and is as shown in Figure 1, comprises a chassis 4; From this mechanism of Fig. 2 is finding out that in use profile can be concrete, is provided with upper slide 21, middle slide plate 22 and lower skateboard 23 in the chassis 4, offers the slide plate mouth on the slide plate; Upper slide 21 is fixed with lower skateboard 23, and when middle slide plate 23 during in original position, the slide plate mouth of three slide plates is a straight line setting; This moment, molten steel flow was maximum, and 4 right ends is connected with a hydraulic cylinder (not shown) respectively on the chassis, and said hydraulic cylinder is fastenedly connected the left and right sides with the chassis through hydraulic cylinder base among Fig. 1 32 and corresponding nut; The right ends of slide plate 22 in the middle of the hydraulic axis of hydraulic cylinder connects respectively; But slide plate 23 is with respect to slide plate move left and right up and down like this, and such setting is a side of considering slide plate 22 in the middle of long-term the use; Feasible easily that side of often using is corroded by molten steel and causes and can't use; As long as, adopt the opposite side work of slide plate mouth, can increase the service life like this through slide plate 23 in the middle of the hydraulic cylinder pulling of opposite side.
Consider the erosion problem at the mouth of a river simultaneously; 4 front end (refers to the opposite side except chassis 4 right ends on the chassis; Also can be the rear end) be provided with a fast sprue-replacing cylinder 31, this fast sprue-replacing cylinder 31 combines corresponding nut 6 to be fixed on the chassis 4 through cylinder holder 311 and steady pin 311, and the cylinder axis of fast sprue-replacing cylinder 31 connects a quick change injection block 5; Said quick change injection block 5 inboards are provided with releases groove 51, releases in the groove 51 and is placed with a subsequent use mouth of a river.When mouth of a river erosion can't be used, can the subsequent use mouth of a river be pushed through fast sprue-replacing cylinder 31, the mouth of a river of corroding is released from quick change injection block 5.Hyperphoric process is carried out in ar gas environment, has removed the whole tundish of replacing mechanism from.Must stop casting if change whole tundish mechanism, can influence the progress of whole casting like this, and improve operating efficiency undoubtedly greatly through improvement of the present invention.
In addition, the present invention need to prove that the nut of mentioning in the literary composition 6 all is to have different models, and the nut mark in the accompanying drawing does not represent it is same nut.
The present invention still has multiple concrete embodiment, and all employings are equal to replacement or equivalent transformation and all technical schemes of forming all drop within the scope of requirement protection of the present invention.
