Set up pouring device for inoculation and spheroidization synchronous positioning mechanism

Abstract

A casting device provided with nucleating, nodulizing and synchronous-positioning mechanisms comprises a casting ladle, a hanging frame and the synchronous-positioning mechanism, wherein the casting ladle comprises a casting container, left-side and right-side connecting shafts symmetrically arranged on two sides of the casting container and a turning handle, the synchronous-positioning mechanism comprises a transmission mechanism and a nucleating agent hanging mechanism, the transmission mechanism is arranged on the side wall of the hanging frame, the lower end of the transmission mechanism is in driving connection with the right-side connecting shaft, the upper end of the transmission mechanism is fixedly connected with the nucleating agent hanging mechanism, and further the nucleating agent hanging mechanism and a molten metal flow nozzle of the casting container are always located in the same vertical direction. The defect that the adding time, the adding position and the adding effect of nucleating and nodulizing agents are not controllable in the prior art is overcome, the transmission mechanism with the transmission ratio 1 is adopted, so that the casting ladle and a nucleating bucket hanging rod are same in turning angle, and accordingly accurate nucleating along with flow in the whole casting process is achieved.

Description

technical field [0001] The invention relates to the technical field of metal pouring equipment, in particular to a pouring device provided with a synchronous positioning mechanism for inoculation and spheroidization. Background technique [0002] The use of inoculation technology has brought a leap forward in the quality of cast iron materials, but the implementation process of conventional inoculation technology leads to unstable quality of cast iron materials, such as: embedding method, which cannot determine the reaction time of the inoculant, nor can it guarantee the inoculant. Uniform distribution; input method, sprinkle the inoculant in advance or in the middle, and then pour the molten metal, or set up a simple shelf above the sprue basin or ladle in advance, but as the ladle is tilted, the inoculant will fall to the slag On the cake, the molten metal cannot enter; in the flushing method, design a special transitional tooling, add the inoculant-nodularizing agent to t...

AI Technical Summary

Problems solved by technology

[0007] The invention overcomes the uncontrollable defects of the adding time, adding position and adding effect of the inoculant and nodulizing agent in the prior art, and provides a ladle with an inoculation-spheroidizing synchronous positioning mechanism, and the ladle adopts The transmission mechanism with a transmission ratio of 1 makes the rotation angle of the ladle the same as that of the inoculation bucket hanging rod, thus ensuring that the inoculation bucket is always located directly above the nozzle of the ladle, and solves the problem that the fixed inoculation bucket is always placed at the same position The inoculant causes the inoculation agent to fail to fall on the outflowing molten metal, resulting in poor inoculation effect, thus realizing accurate inoculation with the flow in the whole pouring process
