Abstract
The invention provides a detachable mechanism for a tundish. The detachable mechanism comprises three sliding plates, i.e. an upper sliding plate, a middle sliding plate and a lower sliding plate, an upper nozzle, an immersion-type lower nozzle and a clamping device, wherein the upper sliding plate and the lower sliding plate are immobile; the middle sliding plate can move left and right; the clamping device is connected with the upper nozzle and the lower nozzle through a spring; and an included angle of 45 DEG is formed between the spring and the casting axis. The mechanism has a simple structure and convenience for operation; the mechanism comprises a detachable drive unit, thus the mechanism has high flexibility; the manner for clamping the nozzles is improved, thus the combination between the nozzles is tighter; and meanwhile, with the adoption of an argon gas sealing system, the accidents of steel leakage caused by the oxidation of plate surfaces are avoided, so that the mechanism has higher safety.
Description
Technical field
The present invention relates to a kind of tundish detachable mechanism, belong to the molten steel casting mechanical equipment technical field.
Background technology
The tundish mechanism part that in casting process, is absolutely necessary, wherein, the submersed nozzle in the mechanism is owing to the erosion of molten steel causes the crack to rupture easily, just need change a new mouth of a river this moment.Tundish of the prior art mechanism comprises that the slide plate up and down and the drive unit at the mouth of a river and mouth of a river clamping device and control flow are formed up and down, is connected through spring between clamping device and the mouth of a river, during use; Making a concerted effort of spring and drive unit formation is vertical; Make stress concentrated relatively, the transmittance process of spring force is complicated, and machine error is big; And lower skateboard be owing to possibly cause moving of plate face in moving, thereby causes up and down well centering of mouth of a river pouring channel.
Summary of the invention
The objective of the invention is to solve above-mentioned technical problem, a kind of tundish detachable mechanism is provided.
The object of the invention is realized through following technical scheme:
A kind of tundish detachable mechanism, following three slide plates in comprising, the mouth of a river and clamping device under filling pipe end, the immersion; Said up and down slide plate is fixed, but slide plate move left and right in the middle of said, and said clamping device is connected through spring with the mouth of a river up and down; Said spring becomes miter angle with the casting axis
Further, above-described tundish detachable mechanism, wherein this mechanism also is provided with a fast replacing device.
Further, above-described tundish detachable mechanism, wherein this mechanism also is provided with an argon gas sealing device in the same side of fast replacing device.
Beneficial effect of the present invention is mainly reflected in: this mechanism structure is succinct, and is easy to operate, has dismountable drive unit; Flexibility ratio is high, and has improved mouth of a river clamping mode, makes that combination is tightr between the mouth of a river; Simultaneously; Adopt the argon gas sealing system, avoid the plate face, have higher security because of oxidation causes the bleed-out accident.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Fig. 1: overall structure vertical view of the present invention.
The A-A generalized section of Fig. 2: Fig. 1.
The left view of Fig. 3: Fig. 1.
Wherein:
21 hydraulic cylinders, 31 springs, 32 baffles
4 argon gas sealing devices, 5 quick change cylinders
The specific embodiment
The present invention has disclosed a kind of tundish detachable mechanism; Like Fig. 1, Fig. 2, shown in Figure 3; But comprise fixed upper slide 11, piece slide plate 13 and be arranged on the middle slide plate 12 of move left and right between the slide plate up and down down; This centre slide plate 12 drives its move left and right through the hydraulic cylinder 21 that is arranged on the mechanism left and right sides, and the pouring channel at the mouth of a river can guarantee centering about the setting of three slide plates made.This mechanism also comprises the mouth of a river and clamping device under filling pipe end, the immersion; Said clamping device is connected through spring 31 with the mouth of a river up and down; Said spring 31 becomes miter angle with the casting axis; The mouth of a river that is arranged so that is like this located to such an extent that stress obtains average dispersion, is difficult for cracking, and it is tightr that the mouth of a river and plate face also combine.And; Between this spring 31 and the clamping device is dismountable, and said spring 31 is outside equipped with baffle 32, for the ease of the replacing at the mouth of a river; This device also is provided with a fast replacing device; Fast replacing device is changed through 5 pairs of mouths of a river of quick change cylinder, is difficult for because bleed-out is caused because of air-breathing oxidation in the mouth of a river when changing for better assurance, and the present invention also is provided with an argon gas sealing device 4 in a side of fast replacing device.
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.
Claims (3)
1. tundish detachable mechanism; It is characterized in that: following three slide plates in comprising; The mouth of a river and clamping device under filling pipe end, the immersion, it is said that slide plate is fixed up and down, but slide plate move left and right in the middle of said; Said clamping device is connected through spring with the mouth of a river up and down, and said spring becomes miter angle with the casting axis.
