Abstract
The utility model provides a tundish refractory material opens and waters pipe, the split type structure of constituteing by tube socket, body and spacing post, the tube socket is the same with body internal diameter and the external diameter homogeneous that sits on it, is equipped with 3 at least card holes on tube socket and body inner wall correspond the position respectively, and the tube socket is connected as an organic wholely through the U-shaped card with the body, is equipped with 2 at least spacing posts on the body along equidistant. The utility model overcomes originally open and water the ring come-up and exceed and open and water the drawback that is washed away by the molten steel behind the pipe, can prevent effectively that resistant material and foreign matter from flowing in the runner channel, avoid the jam of runner channel, even under the condition that the pouring swirl produced, can not be drawn into the foreign matter yet to improve the first blank quality, reduce and open the risk of watering the failure.
Description
Technical field
The utility model belongs to continuous casting installation for casting field, particularly relates to a kind of tundish that controls and opens the refractory material Casting tube watering slag.
Background technology
In sheet billet continuous casting technological process, tundish flow control has two kinds of modes: a kind of is stopper rod flow control, and another kind is sliding plate flow-control.When using stopper rod flow control, after large tank is opened and watered, after can waiting for that tundish liquid level increases to certain altitude, then open stopper, this kind of mode effectively can control centre and unwrap and water slag; When using sliding plate flow-control, need with the use of Casting tube.Utilize Casting tube to be that liquid steel level is promoted to certain altitude, unwrap water the lower quantity of slag to reduce centre.
But, no matter steel Casting tube or refractory material Casting tube, molten steel all will flow into from Casting tube top, this just inevitably causes the resistance to material in molten steel upper strata and foreign matter to flow into ladle canal, both split and watered quality of primary blank and impact, and the inflow of resistance to material and foreign matter very easily causes the blocking of ladle canal, bring the risk opened and water failure.
Summary of the invention
The utility model provides a kind of tundish refractory material Casting tube, and its object is intended to prevent resistance to material and foreign matter from flowing into ladle canal, avoids the blocking of ladle canal, improves quality of primary blank, reduce and open the risk of watering failure.
For this reason, the solution that the utility model is taked is:
A kind of tundish refractory material Casting tube, it is characterized in that, described refractory material Casting tube adopts split-type structural, is made up of base, body and limited post; Base and sit internal diameter of tube body thereon and external diameter all identical, base and inboard wall of tube body correspondence position are respectively equipped with at least 3 hole clippings, and base and body are connected as one by U-shaped card, and body is equidistantly provided with at least 2 limited posts along upper.
Described base height is 80 ~ 120mm.
Described body height is identical with limited post height, is 180 ~ 220mm.
Using method of the present utility model and beneficial effect are:
Casting tube base imbedded tundish bottom and fix.Open after watering, molten steel will be opened and water ring and float, open water ring the resistance to material on molten steel upper strata and foreign matter are blocked in outside, when molten steel face exceed on Casting tube body along after, in inflow Casting tube, and the limited post on Casting tube top continues restriction and opens and water ring and do not washed away by molten steel, and above keeping Casting tube, molten steel surface does not have resistance to material and foreign matter, even if cast whirlpool produces, also foreign matter can not be involved in.When molten steel is full of Casting tube inside, the U-shaped card connecting base and body will be melted by molten steel, and base and body natural separation, operating personnel can be taken out with hook, thus avoid molten steel in casting process Casting tube to be washed away to the field trash of generation.
The utility model overcome former open water ring float exceed Casting tube after the drawback that washed away by molten steel, can effectively prevent resistance to material and foreign matter from flowing into ladle canal, avoid the blocking of ladle canal, even if when pouring into a mould whirlpool and producing, also foreign matter can not be involved in, thus improve and open and water quality of primary blank, reduce and open the risk of watering failure.Avoid former Casting tube is immersed in molten steel simultaneously, is washed the drawback producing field trash, improves steel quality.
Accompanying drawing explanation
Fig. 1 is refractory material Casting tube using state schematic diagram.
In figure: base 1, tundish bottom 2, U-shaped card 3, body 4, limited post 5, open and water ring 6.
Detailed description of the invention
The utility model tundish refractory material Casting tube adopts split-type structural, is made up of base 1, U-shaped card 3, body 4 and limited post 5.Body 4 is seated on base 1, and internal diameter and the external diameter of base 1 and body 4 are all identical.Base 1 with the inwall correspondence position of body 4 are respectively equipped with 4 hole clippings, and base 1 and body 4 are connected as one by U-shaped card 3. on body 4, edge is equidistantly provided with 2 limited posts 5.
For a machine double fluid 50 tons of tundish, base 1 is 200mm with the internal diameter of body 4, and base 1 is highly 100mm, and the height of body 4 is identical with the height of limited post 5, is 200mm.The degree of depth that base 1 imbeds tundish bottom 2 is 50mm, and the diameter watering ring 6 opened by overcoat is 300mm, is highly 60mm.
