Material block segmenting device of iron alloy grain casting machine

Abstract

The invention belongs to the technical field of iron alloy casting block forming continuous production, and particularly relates to a material block segmenting device of an iron alloy grain casting machine. The material block segmenting device of the iron alloy grain casting machine comprises a basic rack, a fixed frame, four guide wheel assemblies, a lifting frame, two hydraulic cylinders, a follow rest, a set of material block segmenting knifes, a set of material stopping rod mechanisms, an electric control device and a cooling system; the horizontal cross sections of material block segmenting knifes are of a grille structure, and the material block segmenting knifes are composed of the first vertical segmenting grille knife, the second vertical segmenting grille knife and the third vertical segmenting grille knife of which the heights are sequentially increased; the material stopping rod mechanisms are composed of a first material stopping rod assembly, a second material stopping rod assembly and a third material stopping rod assembly of which the vertical heights are sequentially increased and a first cooling circulation pipe connected with the first material stopping rod assembly, the second material stopping rod assembly and the third material stopping rod assembly. According to the material block segmenting device of the iron alloy grain casting machine, high-temperature large material blocks to be solidified in a mould can be quickly segmented for one time, and the size and weight of segmented material block units are in accordance with the alloy block feeding standard in steel smelting industry.

Description

technical field [0001] The invention belongs to the technical field of continuous production of ferroalloy ingot molding, and in particular relates to a material block cutting device of a ferroalloy casting machine. Background technique [0002] In the process of iron and steel smelting → primary forming → secondary forming, in order to obtain the chemical and physical properties of a certain type of steel, it is necessary to add some necessary alloy elements regularly and quantitatively during the smelting process, and the most convenient and quick addition method is through The ferroalloy feeder puts ferroalloy material blocks into the steelmaking furnace, and the outer dimension of the material block is called the particle size. Research and practice have shown that ferroalloy blocks with a particle size of less than or equal to 50mm to 70mm are the easiest to melt, and the utilization rate of ferroalloys with this particle size is the highest; while ferroalloys with a pa...

Problems solved by technology

However, after years of application and observation, this casting machine still has the following imperfections: (1) The shape of the honeycomb mold is complex, the effective volume in the mold is small, the utilization rate of the mold material is low, and the mold manufacturing is difficult, which belongs to high Cost Consumables

(2) Due to the poor fluidity of the liquid ferroalloy in the honeycomb mold, the particle size of the condensed ferroalloy block is not uniform
