Abstract

The invention discloses a soaking rod assembly, a device and a process method for spherifying molten iron with a press-in method. The soaking rod assembly comprises a core rod, a soaking cage fixedlyconnected to the lower end of the core rod, and a sleeve fixedly connected to the upper end of the core rod. An opening is formed in the lower end of the soaking cage, and a spherifying agent is arranged in the soaking cage. The device for spherifying the molten iron with the press-in method comprises the soaking rod assembly, a lifting mechanism and a rotating mechanism. The process method of thedevice includes the following steps that (1), the lifting mechanism drives the soaking cage of the soaking rod assembly to be rapidly pressed in a molten iron ladle of one spherifying station to be spherified; (2), after spherifying treatment is completed, the lifting mechanism drives the soaking rod assembly to lift the molten iron ladle away from the spherifying station; and (3), the rotating mechanism drives the soaking rod assembly and the lifting mechanism to rotate to a next spherifying station; and the operation circulates in this way, and spherifying treatment of multiple spherifyingstations is achieved. According to the technical scheme, automatic operation control of spherifying treatment of the multiple spherifying stations is achieved, the spherifying speed is high, the efficiency is high, and the magnesium absorption rate is high.

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, device and process method 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, there are mainly four methods for the existing spheroidizing process, one is the flushing method, and the magnesium alloy or other rare earth alloy spheroidizing agent is placed at the bottom of the spheroidizing bag, and then the molten iron is used for spheroidizing treatment. It has high consumption and low controllability; the second method is the wire feeding method, which wraps the magnesium alloy nodulizer into a wire shape and adds it into molten iron with wire feeding equipment, which has high consumption, low purity of m...
