However, the through hole in the prior art is a circular through hole, and the side surface of the circular through hole is of an arc-shaped structure, and the distance between the circular through hole and the circular through hole is gradually increased from the middle to two sides, so that the amount of the liquid flowing into the molten steel channel and the pressure at the distance are uneven, and the amorphous spraying belt is provided with a plurality of shrinkage grains in the direction of extension degree, which are formed by different shrinkage amounts when the amorphous spraying belt is rapidly cooled due to different local pressures, large pressures and small pressure part densities, and the existence of the shrinkage grains breaks the wavy grains on the belt surface, which are arranged along the width direction of the amorphous spraying belt due to the shrinkage of the rapid cooling crystallizer, thereby affecting the quality and the magnetic performance of the belt surface.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a non-crystalline spray nozzle for making level and smooth strip face.
The utility model discloses an innovation point lies in changing round through-hole into square through-hole for equal with both sides in the middle of the interval between through-hole and the through-hole, the liquid flow volume and the pressure that interval department got into in the molten steel passageway are even, are difficult because of the uneven and local liquid steel volume of pressure is insufficient forms the shrink line, and the area is comparatively level and smooth.
In order to realize the purpose of the utility model, the technical proposal of the utility model is that: the utility model provides a non-crystal spray belt nozzle for making level area face, nozzle body including rectangular shape, nozzle body's bottom is equipped with one and spouts the seam along nozzle body length direction arranges, and nozzle body bottom still is equipped with two gas joints, and two gas joints are located respectively and spout seam both sides and parallel with spouting the seam, and spout seam and gas joint both ends are sealed, spout the seam top be equipped with spout a molten steel passageway of seam intercommunication, the gas joint top be equipped with the air current passageway of gas joint intercommunication, air current passageway one end opening one end is sealed, molten steel passageway both ends are sealed, molten steel passageway top is equipped with a plurality of quad slit with molten steel passageway intercommunication, the quad slit is arranged along molten steel passageway's length direction equidistant.
Further, a liquid collecting tank is arranged at the top of the nozzle body, and the tops of the square holes are communicated with the liquid collecting tank. The molten steel in each through hole is uniformly filled, the stable supply amount of the molten steel is ensured, and the strip surface is more smooth and uniform.
Further, the square hole is a rectangular hole, and the long side of the rectangular hole is parallel to the length direction of the molten steel channel.
Further, the distance between the two adjacent square holes at the molten steel channel is 2 +/-0.01 mm. This spacing is the least likely to form shrink lines.
Furthermore, four corners of the square hole are provided with R corners. On one hand, the stress can be eliminated, and on the other hand, the manufacture is convenient.
Further, the cross-section of quad slit enlarges from collecting tank one end to molten steel passageway one end gradually, the cross-section of quad slit along long limit direction is trapezoidal form, and the inclination of the hypotenuse of trapezoidal form is 2.6. The two ends of the square hole in the length direction form a gradually expanding structure from top to bottom, so that the flow quantity of the space between the through hole and the through hole is increased, and the shrinkage lines are further reduced.
Further, the width of the square hole is 6 +/-0.01 mm, and the length of the square hole at the molten steel channel is 27.1 +/-0.01 mm. The aperture at this time is not likely to form a shrink pattern.
The utility model has the advantages that:
1. the utility model discloses in change the through-hole into square through-hole for equal with both sides in the middle of the interval between through-hole and the through-hole, the flow volume and the pressure that interval department got into in the molten steel passageway are even, are difficult for forming the shrink line, and the area face is comparatively level and smooth.
2. The utility model discloses in make the molten steel in every through-hole fill evenly and guarantee stable molten steel supply, the area face is more level and smooth even.
