Manufacturing equipment and method of novel silicon iron rare earth magnesium spheroidizing agent

Abstract

The novel silicon iron rare earth magnesium nodulizer manufacturing equipment comprises a preparation box and further comprises a cooling mechanism, a fixing plate and a fixing frame, the fixing frame is welded to the side face of the preparation box, the side face of the preparation box is connected with the cooling mechanism through the fixing plate, and the cooling mechanism comprises a negative pressure machine, a flow guide frame, a soft guide pipe and a refrigerator. Two sets of negative pressure machines are installed on the top of the fixing plate, the input ends of the negative pressure machines are fixedly connected with a flow guide frame, a refrigerator is arranged below the fixing plate and used for making cold air, and the output end of the refrigerator is connected with the flow guide frame through a soft guide pipe. The negative pressure machine is installed on the side face of the preparation box to be matched with the refrigerator for use, blocky rare earth ferrosilicon magnesium can be cooled conveniently, and the hydraulic pump is installed on the side face of the preparation box to be connected with the hydraulic rod and the clamping plate to be matched with the limiting block in the preparation box for use, so that the rare earth ferrosilicon magnesium can be extruded and spheroidized conveniently; and preparation and storage of the rare earth ferrosilicon magnesium are facilitated.

Description

technical field [0001] The invention relates to the technical field of manufacturing a ferrosilicon rare earth magnesium nodularizing agent, in particular to a manufacturing equipment and a method for a novel ferrosilicon rare earth magnesium nodularizing agent. Background technique [0002] Rare earth magnesium ferrosilicon alloy refers to an alloy formed by melting ferrosilicon, calcium, magnesium, rare earth, etc. It is a good nodularizer with strong deoxidation and desulfurization effects. Ferrosilicon, rare earth ores, and metal magnesium are the main raw materials for the production of rare earth magnesium ferrosilicon alloys. The production of rare earth magnesium ferrosilicon alloy is carried out in submerged arc furnace, which consumes a lot of power, and can also be produced in intermediate frequency furnace. [0003] The production equipment of the ferrosilicon rare earth magnesium nodularizing agent in the prior art has the following drawbacks: during the pressi...

AI Technical Summary

Problems solved by technology

[0003] The production equipment of ferrosilicon rare earth magnesium spheroidizers in the prior art has the following disadvantages: during the pressing process of rare earth magnesium ferrosilicon, the temperature is high and the heat rises due to the high pressure, but the prior art is not convenient for rare earth magnesium ferrosilicon. Effective cooling leads to poor spheroidizing effect of rare earth magnesium ferrosilicon processing, and cannot guarantee the preparation effect of ferrosilicon rare earth magnesium spheroidizer
