Problems solved by technology

Generally, after the molten metal is filled into the ladle, the molten metal is in a relatively static state, and the impurities inside the molten metal are not easy to float to the surface of the molten metal. In addition, the bubbles are not easy to be discharged from the molten metal. During the casting process It is easy to generate pores in the casting, which affects the quality of the casting

Embodiment Construction

[0017] As shown in Figures 1 to 4, a ladle molten metal pure energization process, after the molten metal is injected into the ladle 1, through the rotation or vibration of the ladle 1, the molten metal in the ladle 1 is in a state of motion, removing Impurities floating on the surface of the molten metal are then poured into the molten metal.

[0018] For implementing the invention, a ladle molten metal pure energizing device is used. The ladle 1 is placed above the molten metal pure energizing device. The molten metal pure energizing device includes a transmission structure that drives the ladle to rotate or vibrate. . In order to enhance the movement effect of the molten metal in the steel ladle 1, the steel ladle 1 is generally inclined at a certain angle, and the inclination angle α is 5° to 70°. In addition, a protrusion 6 is provided on the inner wall of the ladle, and the protrusion 6 can be from The mouth of the ladle 1 runs through to the bottom of a continuous stri...

Abstract

The present invention relates to smelting process, and is especially method of purifying and energizing metal melt in steel ladle. The method is to rotate or vibrate the steel ladle and to make the metal melt inside the steel ladle in moving state and to eliminate the impurity floating on the surface of the metal melt before casting. The said method can exhaust the impurity bubble, store certain quantity of kinetic energy in the metal melt, lower the casting temperature by 100-120 deg.c, improve the flowability and cavity filling property of the metal melt and improve the casting performance.

Description

technical field [0001] The invention relates to a smelting process, in particular to a process for purely energizing ladle molten metal. Background technique [0002] In the process of steelmaking and ironmaking, the molten metal is first placed in the ladle, and then the molten metal is poured into the cavity of the mold. Generally, after the molten metal is filled into the ladle, the molten metal is in a relatively static state, and the impurities inside the molten metal are not easy to float to the surface of the molten metal. In addition, the bubbles are not easy to be discharged from the molten metal. During the casting process It is easy to generate pores in the casting, which affects the quality of the casting. In addition, in order to have good filling and fluidity when the molten metal is injected into the cavity of the mold, it is generally required that the molten metal has a higher melting temperature. Contents of the invention [0003] In order to improve th...
