Reference numbers in the figures: 10. a straight barrel 20, a ladle opening 30, an arc-shaped bent pipe 31 and a one-way diaphragm.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Examples
As shown in fig. 1, the method for manufacturing a casting ladle according to the present embodiment includes the following steps:
s1, preparing raw materials, namely sequentially putting the raw materials used by the ladle into a stirrer for mixing and stirring, and then adding 15% of water for mixing to obtain a mixed solution for later use;
s2, pouring the mixed solution into a vacuum pug mill for marking to obtain a straight barrel 10, a ladle opening 20 and an arc-shaped bent pipe 30 for later use;
the vacuum pugging is that when pug enters a vacuum chamber of a vacuum pug mill, the air pressure in air bubbles in the pug is greater than the air pressure in the vacuum chamber, the bubbles expand to reduce the pressure and reduce the thickness of the pug film, at the moment, the strength of the pug film is correspondingly reduced, when the pressure difference between the air bubbles and the vacuum chamber is enough to break the pug film, the air is pumped away in the vacuum chamber, if the pug strips are thick or the air bubbles are deep, the pressure difference is not enough to break the pug, the air can remain in the pug, and the factors influencing the vacuum pug milling mainly comprise the vacuum degree, the moisture and uniformity of added mud cakes, the temperature, the feeding speed, the structure of the pug mill and the like;
the mud cake obtained by filter pressing has uneven distribution of water and solid particles. The pug has an oriented structure, so that the blank shrinks unevenly, and drying and firing cracks are caused. The mud cake contains a large amount of air, the air content is 7% -10%, the air blocks the wetting of solid particles and water, reduces the plasticity of the mud, increases the elastic deformation of the mud during molding, and causes product defects. After the vacuum pugging, the volume of the pug air can be reduced to 0.5% -1%, and due to the kneading and extruding effects of the spiral on the pug, the directional structure of the pug is improved, and the components are more uniform. The shrinkage of the green body is reduced, the drying strength is multiplied, and the product performance is obviously improved;
s3, placing the straight barrel, the ladle opening and the bent pipe with the arc shape into a metal mold for molding, and shaping the molded straight barrel 10, the ladle opening 20 and the bent pipe with the arc shape 30 to obtain a semi-finished product, wherein the molded ladle opening 20 extends out of the top of the straight barrel, one end of the arc-shaped bent pipe 30 is communicated with the straight barrel 10, the other end of the arc-shaped bent pipe is communicated with the ladle opening 20, and the end part of the arc-shaped bent pipe 30 connected with the ladle opening 20 is parallel to the top of the straight barrel 10;
