Abstract

The invention discloses a segmenting type iron alloy grain casting machine and a technology method for producing iron alloy casting grains. The segmenting type iron alloy grain casting machine comprises an equipment rack, a chain driving device, a finished material block receiving device, a chain tensioning device, an upper two-line inclined track, a lower two-line inclined track, two annular plate type conveying chains, a cooling spraying system, an iron alloy liquid casting heat preservation chute, a water recovery system, coating spraying system and an electronic control system; the equipment rack is composed of a head rack body, a middle rack body and a tail rack body, the middle rack body is provided with a material block segmenting mechanism which is composed of a fixed frame, a material stopping device, four guide wheel assemblies, a lifting frame, a segmenting device, two hydraulic cylinders, a fixed frame cooling circulation system and a lifting frame cooling circulation, and the annular plate type conveying chains are connected with multiple tray moulds. According to the segmenting type iron alloy grain casting machine and the technology method for producing the iron alloy casting grains, a whole set of processes, such as casting, segmenting, condensing and collecting, of the iron alloy grains can be automatically completed for one time, iron alloy material blocks are uniform in granularity and consistent in weight and can be conveniently and quantificationally used by a user, and the productivity is improved.

Description

technical field [0001] The invention belongs to the technical field of continuous production of ferroalloy ingot molding, and in particular relates to a split-type ferroalloy casting machine and a process for producing ferroalloy casting pellets. 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 50 mm to 70 mm are the easiest to melt, and the utilization rate of ferroalloys with this particle size is the hig...

AI Technical Summary

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

The long-term uninterrupted vibration of the vibrating device will cause great damage to the conveyor chain device and the mold itself, reducing the service life of related equipment and increasing the cost of spare parts

In addition, the vibration process also affects the operation accuracy and stability of the conveyor chain and even the entire casting machine system, and the noise and dust during vibration also affect the environmental protection indicators
