Abstract

The invention discloses a pressing-in method spheroidizing molten iron rod soaking assembly comprising a core rod, a soaking cage fixedly connected to the lower end of the core rod and a sleeve fixedly connected to the upper end of the core rod; the lower end of the soaking cage is opened to form a containing pace for containing a spheroidizing agent, the surface of the core rod and the surface ofthe soaking cage are wrapped with refractory layers, and the refractory layer on the surface of the soaking cage is provided with a plurality of exhaust holes penetrating through the soaking cage. Inthe technical scheme, the rod soaking assembly is driven by external force to directly press the spheroidizing agent into molten iron, and the molten iron enters the soaking cage from the multiple exhaust holes to be in contact with the spheroidizing agent to make a reaction for spheroidizing treatment; meanwhile, spheroidizing agent steam discharged from the exhaust holes has the effect of stirring the molten iron, molten iron spheroidizing is even, and the spheroidizing quality of the molten iron is improved; and the pressing-in method spheroidizing molten iron rod soaking assembly is simple in structure, convenient to disassembly and assembly, safer in operation, free of blockage, long in service life and low in using cost.

Description

technical field [0001] The invention relates to the technical field of spheroidizing molten iron in metallurgy and foundry industries, in particular to a dipping rod assembly for spheroidizing molten iron by pressing. Background technique [0002] Spheroidizing treatment is a process of obtaining nodular graphite by treating cast iron liquid, so as to obtain nodular cast iron with better mechanical properties. At present, the process method of using dipping rods in molten iron spheroidization is magnesium spraying method, which uses gas as a carrier to spray passivated magnesium particles into molten iron. Chinese patent authorization announcement number CN201459176 U discloses a ball Powder spraying gun, the core of the dipping rod used is equipped with a powder spraying tube for spraying powder, which can be sprayed into the spheroidizing bag within a specified time by adjusting the injection pressure according to the size of the spheroidizing treatment. Different amounts...
