Abstract
The utility model relates to a pouring basket spruing pipe, and the pouring basket spruing pipe mainly solves the problems that the spruing is automatic and the vortex slag-entrapment is not generated. The utility model comprises a spruing pipe body (1), a floating ring (2) suited outside the spruing pipe body (1); a step (11) preventing the floating ring (2) from being disengaged from the spruing pipe body (1). The steel ladle steel liquid enters into the pouring basket, the floating ring (2) is lifted simultaneously along with the lift of the steel liquid level, to reach a preset steel liquid height, due to the internal diameter of the floating ring (2) being smaller than the top end external diameter of the spruing pipe body (1), the floating ring (2) is locked at the top end of the spruing pipe body (1), and therefore to support the spruing pipe body (1), the spruing pipe body (1) is subjected to an elevating force added by the floating ring (2), the spruing pipe body (1) is lifted under the function of the elevating force, and the steel liquid flows in a water gap from the bottom of the spruing pipe body (1), thereby to realize the automatic spruing. The utility model has the advantages that the operation is convenient, the airtightness before spruing is good, the spruing can be automatic and the vortex slag-entrapment is not generated.
Description
Technical field
The utility model relates to a kind of centre and unwraps depositing.
Background technology
The steel current control mode of continuous casting tundish can be divided into stopper control and slide plate is controlled two big classes, and the mode of watering is unwrapped in corresponding centre also just to be had stopper to open to water to open with non-stopper and water.Because slide plate itself be difficult to be realized opening and watered, to water all be to adopt to open depositing and open the form of watering so general non-stopper is opened.The two is compared, and it is more cheap to open depositing, need not plant equipment, and the fault rate of use is also low.But opening the technology form of watering from opening depositing, enter the molten steel of tundish, is that rising by its liquid level overflows into out depositing and realizes that opening of tundish water mostly, opens depositing or come-up or melting loss thereafter.When molten steel overflowed into out depositing, the scum silica frost on the molten steel face also was involved in out to some extent depositing.Water plug as floating type the opening of the disclosed tundish of Chinese patent ZL99224390.4, though it also waters plug for floating type opening, its resemblance is the synthetic of hollow ball and conical plug, be installed on the middle water containing opening top equally, yet be after the tundish preheating, open and water preceding installation that working condition is poor.The refractory material characteristic of conical plug determines that the precision of its appearance and size can not be very high, and the faying face at the cock body and the mouth of a river does not have effective containment measures, so there is the possibility of leaking molten steel in advance.And the liquid level of opening when watering is low, and it is assorted to produce vortex volume slag folder when molten steel enters the mouth of a river.
Summary of the invention
The purpose of this utility model be to design a kind of easy to use, open and water preceding good airproof performance, but and automatic casting, the depositing of opening that does not produce vortex volume slag.
The utility model comprises opening and waters body that said opening watered body top external diameter greater than the bottom external diameter; This opens the external also sheathed floating ring of depositing, and this floating ring internal diameter waters body top external diameter less than opening.
Further, said opening watered the body top and is provided with one and prevents that floating ring is separated from the step that waters body, can lift simultaneously to open and water body and rise, and realizes automatic casting.
Said opening watered the making of body employing ceramic fibre material.
The utility model waters body owing to adopt floating ring to lift to open, and can realize automatic casting, and opens that molten steel reach a certain height when watering, thereby the possibility of thoroughly having avoided the scum silica frost of molten steel to be involved in the mouth of a river.
In addition, opening the shape why depositing is designed to " pipe ", is in order to make when the tundish preheating mouth of a river, bottom and slide gate nozzle also obtain sufficient preheating.Also because the location is installed under the cold bag state of tundish, make operating process fast and convenient, labour intensity is low.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure; 1 waters body 11 and is step for opening
2 is floating ring
3 is that tundish brick cup 4 is the mouth of a river
The specific embodiment
As shown in Figure 1, the utility model comprises opening and waters body 1, opens and waters body 1 top external diameter greater than the bottom external diameter; This is opened and waters body 1 an outer also sheathed floating ring 2, and these floating ring 2 internal diameters water body 1 top external diameter less than opening.
Open and water body 1 and floating ring 2 together with the tundish preheating, ladle molten steel enters tundish, rising along with the molten steel face, floating ring 2 rises simultaneously, arrive predetermined molten steel height, because these floating ring 2 internal diameters water body 1 top external diameter less than opening, floating ring 2 is fastened on to open and waters body 1 top, thereby hold to open and water body 1, open and water body 1 and be subjected to these additional buoyancy of floating ring 2, its bottom is separated from tundish brick cup 3, opens and waters body 1 come-up, molten steel flows into the mouth of a river 4 from opening the bottom of watering body 1, and tundish is automatically realized opening watering.
The utility model is said to be opened and waters body 1 top and also can be provided with one and prevent that floating ring 2 is separated from the step 11 that waters body 1, has increased floating ring 2 and has lifted and open the stress surface that waters body 1.
The height that waters body 1 is opened in adjusting, can make the liquid level of opening when watering reach 500mm.
Open and water body 1 and adopt lightweight refracrory to make as ceramic fibre material.The present invention can be generalized on all no stopper tundish and uses.
Claims (3)
1. depositing is unwrapped in a centre, comprises opening watering body (1), it is characterized in that, said opening watered body (1) top external diameter greater than the bottom external diameter; This is opened and waters the outer also sheathed floating ring (2) of body (1), and this floating ring (2) internal diameter waters body (1) top external diameter less than opening.
2. depositing is unwrapped in a kind of centre as claimed in claim 1, it is characterized in that, said opening watered body (1) top and be provided with one and prevent that floating ring (2) is separated from the step (11) that waters body (1).
3. depositing is unwrapped in a kind of centre as claimed in claim 1 or 2, it is characterized in that, said opening watered the making of body (1) employing ceramic fibre material.
