Abstract
The utility model discloses a continuous tundish which comprises a steel shell, a permanent lining and a work lining. The steel shell wraps the permanent lining which wraps the work lining. A tundish containing cavity is arranged in the work lining. The work lining 8-12cm in thickness is made of siliceous dry materials. Compared with the prior art, by the work lining made of siliceous dry materials, good washing resistance, corrosion resistance, thermal stability and stripping resistance are achieved, comprehensive material cost is lowered, product operation effectiveness is improved and the like. In addition, the continuous tundish is simple construction method, and the service life of the work lining of the continuous tundish is prolonged effectively.
Description
Technical field
The utility model relates to a kind of continuous casting tundish.
Background technology
The continuous casting tundish is the intermediate receptacle between ladle and crystallizer, and continuous casting played very important effect smoothly.It has stores molten steel, stable and buffering steel flow, stabilized steel coolant-temperature gage, shunts and go deimpurity effect.For the molten steel that satisfies strict smelting requirements and long period stops, require the continuous casting tundish to have outside good fire resistance, need also to have that the opposing steel flow is washed away, the good anti-corrosion damage performances such as erosion of high-temperature molten steel.The continuous casting tundish is comprised of steel casing, permanent lining and work lining usually.Under the prior art condition, its work lining mainly adopts heat-insulating shield or fireproof coating.And the anti-corrosion damage poor performance of heat-insulating shield and fireproof coating, service life is short.
Summary of the invention
Problem to be solved in the utility model is the anti-corrosion damage performance of enhancing work lining.
For addressing the above problem, the scheme that the utility model adopts is as follows:
A kind of continuous casting tundish comprises steel casing, permanent lining, work lining.The permanent lining of steel casing parcel, permanent lining parcel work lining is the tundish cavity volume within the work lining.Wherein, the work lining adopts siliceous dry materials.The working lining layer thickness is 8cm-12cm.
Technique effect of the present utility model is: compared to the prior art, adopt the work lining of siliceous dry materials to have good flushing resistance, the good and thermal shock resistance of erosion-resisting characteristics, anti-strip is good, the material integrated cost reduces, the characteristics such as product on-road efficiency lifting.Construction method is easy, can effectively improve and extend the service life of continuous casting liner in dundish layer.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with Figure of description, the utility model is described in further details.
As shown in Figure 1, a kind of continuous casting tundish comprises steel casing 1, permanent lining 2, work lining 3.The steel casing 1 permanent lining 2 of parcel, permanent lining 2 parcel work linings 3 are tundish cavity volume 4 within work lining 3.Its bottom comprises opening 5, and the edge of opening 5 includes pocket block 6.6 pairs of openings of pocket block play the effect of protection.The lining 3 of wherein working adopts the siliceous dry materials of high-strength, and thickness is 8cm-12cm.
Claims (2)
1. a continuous casting tundish, comprise steel casing, permanent lining, work lining; The permanent lining of steel casing parcel, permanent lining parcel work lining is the tundish cavity volume within the work lining; It is characterized in that, described work lining adopts siliceous dry materials.
2. continuous casting tundish as claimed in claim 1, is characterized in that, described working lining layer thickness is 8cm-12cm.
