Abstract
The utility model relates to a composite water supply mouth for continuous casting ladles, which belongs to functional refractory material used for steel making continuous casting. The water supply mouth can be matched with a water discharge mouth for use, and is mainly used for casting of ladles. The utility model is characterized in that the main body of the water supply mouth is inlaid with a steel receiving mouth and a steel discharge mouth to form the composite body, wherein, the steel receiving mouth and the steel discharge mouth have different material from the main body of the water supply mouth. The steel receiving mouth can be a bowl-shaped funnel or a hemispherical funnel; a steel flowing channel forms a frustum cone which is bigger in the upper part and smaller in the lower part; the steel discharge mouth uses a straight pipe with an equal diameter, and is communicated between the upper part and lower part to form a cavity body. Compared with the water supply mouth used currently, the utility model has the advantages of safe use and long service life.
Description
The utility model belongs to the steel-making continuous casting functional refractory, and it cooperates with the following mouth of a river, is mainly used in basket pouring.
Iron and steel enterprise's employed tundish filling pipe end in continuous casting workshop is a truncate hollow cone of inversion that comprises steel-connecting port, ladle canal, tapping hole at present.Its steel-connecting port is tubaeform, and ladle canal is the straight-through shape of pipe, and its material mostly is high alumina matter.Steel-connecting port is the line contact with contacting of stopper chock plug because of being horn-like, is easy to be subjected to the washing away of molten steel, etch, and it is not tight to cause chock plug contact with horn mouth, causes out of control or bleed-out, so that influence production.Though on material, change corundum matter, zirconium matter into by high alumina matter, improved antiscour, corrosion resistance, can not solve the defective of bringing on its modeling structure, and production cost and price all there is increase, use and uneconomical.For this reason, use from the Mechanical Builds of filling pipe end and material that to improve be very necessary.
The purpose of this utility model is that the shape and structure and the material of change steel-connecting port, tapping hole to improve the comprehensive result of use of filling pipe end, make it good use value.
The purpose of this utility model solves by the following technical solutions: described continuous casting tundish combined type filling pipe end, by inverted truncate hollow cone and comprise that the cavity body of steel-connecting port, ladle canal, tapping hole forms, it is characterized in that being inlaid with on body with it, the steel-connecting port mosaics and the tapping hole mosaics of unlike material constitute complex.But one of the steel-connecting port bowl-shaped funnel of its cavity body, hemispheroid funnel, ladle canal are up big and down small truncate taper shapes, and tapping hole is isometrical straight tube-like, and their up/down perforations form cavity body.The back cut diameter of ladle canal is greater than the lower port diameter of steel-connecting port funnel, the end opening of ladle canal and tapping hole equal diameters.
Combined type filling pipe end body is a high alumina refractories, and the material of steel-connecting port, tapping hole mosaics is the optional one of corundum matter, zirconium matter.
The utility model and existing continuous casting tundish are with the filling pipe end following superiority of having compared:
1, with tubaeform bowl-type, the hemispheroid funnel shape steel-connecting port of changing into of filling pipe end, increased the contact area with the stopper chock plug, make it identical well, control steel stream.
2, ladle canal is up big and down small, its funnel tapping hole greater than steel-connecting port suitable for reading, molten steel is eddy current and rotates into crystallizer, the effect that liquid steel temperature is evenly distributed is arranged, during forming, the minimizing steel billet cracks and the off-square phenomenon, improve billet quality, and slowed down the wash away corrosion function of molten steel, reduced eroding velocity mouth of a river vias inner walls.
3, zirconium matter, the corundum material inlayed of steel-connecting port, tapping hole anti-ly washes away, anti-erosion, simultaneously, the bell mouth of steel-connecting port is close with the tapping hole diameter, deteriorates seriously at the stopper chock plug, when ineffective, play the effect of metering nozzle simultaneously, stabilized steel flow velocity degree prolongs the duration of pouring.
