Abstract
The utility model provides an anti-sticking, fast replacing immersion water gap which comprises a sliding surface, a bowl part, an entity and a sheet iron and so on. The utility model is characterized in that: the surrounding of the sliding surface equals or goes beyond the surrounding of the sheet iron. When the improved anti-sticking, fast replacing immersion water gap is used, the contact surface of the two water gaps during the fast replacement process is changed from the contact surface of iron sheet to iron sheet to the contact surface of fire-endurance material to fire-endurance material or the contact surface of fire-endurance material to iron sheet. In this way, when the contact surface of the two water gaps passes through the molten steel from the central water gap, the molten steel is blocked by the sliding surface and does not drop onto the iron sheet. In addition, the sliding surface material is not adhesive with the molten steel, which enables the fast replacement to be realized.
Description
Technical field
The utility model relates to a kind of quick replacing submersed nozzle, specifically, is a kind of preventing by the quick replacing submersed nozzle of molten steel adhesion.
Technical background
Along with the development of continuous casting technology, also more and more higher to the requirement of continuous casting billet quality.When changing submersed nozzle in casting process, the molten steel that flows into crystallizer is exposed in the air at short notice, influences continuous casting billet quality easily.In order to guarantee continuous casting billet quality; need the whole process protection cast; thereby the submersed nozzle quick replacement device arises at the historic moment, and simultaneously supporting submersed nozzle has also been proposed special requirement: submersed nozzle must have sliding function, can change smoothly when not stopping watering to guarantee submersed nozzle.The existing immersion water gap bowl portion periphery of changing fast all is surrounded by the thick iron sheet of one deck 1mm-3mm, play the effect at the protection mouth of a river, and iron sheet is usually less than sliding surface 1mm-2mm.Molten steel flows on the iron sheet of joint, two mouths of a river easily in submersed nozzle replacing process fast, causes the submersed nozzle under being replaced and the submersed nozzle of new clothes to be sticked together, and influences execute-in-place.
Summary of the invention
The problem that the utility model easily sticks together when solving above-mentioned quick replacing, a kind of improved quick replacing submersed nozzle is provided, this mouth of a river comprises sliding surface, bowl portion, body, iron sheet etc., and principal character of the present utility model is: and the sliding surface periphery is concordant with the iron sheet periphery or exceed the iron sheet periphery.
The utility model can also have following feature: sliding surface to the top of iron sheet apart from 5mm≤h＜H.
The utility model is preferably in and coats a lubricant layer on the sliding surface, bag one refractory fiber floor on the following body periphery except that the iron sheet protection of bowl portion, and refractory fibre can play insulation and anti-oxidation effect after baking.
The utility model compared with prior art has the following advantages and good effect: use this improved quick replacing submersed nozzle, two mouth of a river contact-making surfaces change contacting of refractory aggregate and refractory aggregate into by iron sheet and contacting of iron sheet in the replacing process fast, or refractory aggregate and the common of iron sheet contact, when the contact-making surface at such two mouths of a river passes through the molten steel of middle water containing opening outflow, molten steel is blocked by sliding surface and can not be dripped on the iron sheet, and sliding surface material and molten steel can not stick together, so can really realize quick replacing.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further details:
Fig. 1: change submersed nozzle prior art structural representation fast;
Fig. 2: change submersed nozzle prior art structure vertical view fast;
Fig. 3: example structure schematic diagram of the utility model;
Fig. 4: example structure vertical view of the utility model.
With reference to accompanying drawing, this submersed nozzle comprises: sliding surface 1, bowl portion 2, body 3, iron sheet 4, refractory fiber paper 5 etc.
The specific embodiment
Fig. 3 and quick replacing submersed nozzle shown in Figure 4 comprise sliding surface 1, bowl portion 2, body 3 and iron sheet 4, the refractory fibre 5 etc. that scribble a lubricant layer.Molten steel flows on the iron sheet 4 of joint, two mouths of a river easily in the prior art instant change nozzle process in order to overcome, the defective that causes the submersed nozzle of submersed nozzle under being replaced and new clothes to be sticked together.Main improvement design of the present utility model is that the sliding surface 1 and the position of iron sheet are improved, and is concordant with iron sheet 4 peripheries as sliding surface 1 periphery, or sliding surface 1 exceeds iron sheet 4.Sliding surface 1 to the top of iron sheet 4 apart from 5mm≤h＜H, and bowl portion body periphery except that iron sheet 4 is protected below 2 is surrounded by one deck refractory fibre 5.
Claims (5)
1, a kind of quick replacing submersed nozzle comprises sliding surface (1), bowl portion (2), body (3) and iron sheet (4), it is characterized in that sliding surface 1 periphery is concordant with iron sheet 4 peripheries or exceeds iron sheet 4 peripheries.
2, quick replacing submersed nozzle as claimed in claim 1 is characterized in that, sliding surface 1 to the top of iron sheet 4 apart from 5mm≤h＜H.
3, quick replacing submersed nozzle as claimed in claim 1 or 2 is characterized in that sliding surface scribbles a lubricant layer.
4, quick replacing submersed nozzle as claimed in claim 1 or 2 is characterized in that, the following body periphery except that the iron sheet protection of bowl portion is surrounded by a refractory fiber floor (5).
5, quick replacing submersed nozzle as claimed in claim 4 is characterized in that sliding surface scribbles a lubricant layer.
