Abstract

The invention relates to the technical field of a semi-continuous casting flow control device, in particular to high-precision silver-copper rod semi-continuous casting equipment with a stirring and vibration device. The equipment comprises a semi-continuous casting tundish, an end fixed frame, a rotating shaft, a lifting mechanism, a rotating mechanism, a flow adjusting mechanism, a graphite sleeve part, a top cover and a controller. The end fixed frame is mounted on the semi-continuous casting tundish. The rotating shaft is rotationally mounted on the end fixed frame. The lifting mechanism and the rotating mechanism are mounted on the end fixed frame. The output end of the lifting mechanism and the upper end of the rotating shaft are connected in a clamped manner. The output end of the rotating mechanism is engaged with the peripheral wall of the lifting mechanism. The work end of the rotating mechanism is arranged on the peripheral wall of the rotating shaft along the axis of the rotating shaft. The flow adjusting mechanism is mounted at the bottom of the semi-continuous casting tundish. The graphite sleeve part is mounted at the bottom end of the semi-continuous casting tundishand communicates with the interiorof the semi-continuous casting tundish. The top cover is arranged at the upper end f the semi-continuous casting tundish in a manner of being capable of being openedand closed. By means of the scheme, the property of forming materials is more excellent, the manual cost is reduced, and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of semi-continuous casting pouring flow control devices, in particular to semi-continuous casting equipment for high-precision silver-copper rods with a stirring and vibrating device. Background technique [0002] The production of silver-copper rods in the semi-casting industry was originally a primary smelting process in which silver was directly put into copper liquid. The shortcoming of this technique is: (1) the burning loss of silver is serious. Putting the silver into the copper liquid at 0.25, the silver content of the silver-copper alloy produced can only reach about 0.08%, and about 60% of the silver is lost by oxidation and burning; (2) the silver-copper alloy ingot is severely segregated; The tensile strength and hardness of silver-copper alloy profiles are lower than the standard requirements. After adopting the secondary smelting process of silver-copper intermediate alloy, the silver content...
