Iron alloy grain casting machine

Abstract

The invention belongs to the technical field of pig casting machines for continuously producing casting pigs, and in particular relates to an iron alloy grain casting machine, which consists of a chain type slope conveyor, a grain casting die, a slurry spraying mechanism, a water cooling mechanism, a shocking device, an iron alloy liquid pouring insulation chute, a finished grain casting product receiving hopper and an electric control device, wherein the chain type slope conveyer consists of a conveyor frame, a chain inclined rail, a conveyor driving device, a conveyor tensioning and rotating device, and an annular roller chain; the slurry spraying mechanism consists of a stirring device, a slurry spraying stirring tank, a slurry spraying tank, a coating slurry sprayer and a slurry return groove; the water cooling mechanism consists of a water sedimentation tank, a water cooling tank connected with the water sedimentation tank through a water connecting pipe, a cold water sprayer anda water return groove; and the shocking device consists of a shocking bracket, a shocking driving device, an eccentric block, a fixed pin roll, a connecting rod, a reciprocating rod, a guide sleeve, a spring and a contact. The iron alloy grain casting machine completes a series of work procedures such as pouring, cooling, demolding and collecting iron alloy grains at one time and reduces labor intensity and production cost.

Description

technical field [0001] The invention belongs to the technical field of iron casting machines for continuous production of cast iron blocks, in particular to an iron alloy pellet casting machine. Background technique [0002] As we all know, in the process of iron and steel smelting → primary forming → secondary forming, in order to obtain the chemical and physical properties of a certain steel type, it is necessary to add some necessary alloying elements regularly and quantitatively. The feeding machine puts ferroalloy material into the furnace. When the maximum diagonal size of the ferroalloy material is small or equal to 50mm~70mm, it is easy to melt, but the particle size is too small (less than 10mm) and it is easy to burn the ferroalloy and reduce the ferroalloy raw material. utilization rate. Therefore, the industry often sets the production index of ferroalloys as ferroalloy lumps with a particle size of 50mm to 70mm, and the utilization rate of ferroalloys with this...

AI Technical Summary

Problems solved by technology

[0005] 1. The specifications are different. The mold specifications of the cast iron machine are not suitable for the requirements of the particle size of the iron alloy block ≤ 50mm ~ 70mm

[0006] 2. Unable to demould, pig iron has a large volume and single weight, and can be demoulded by its own weight, while the single weight of ferroalloy particle size ≤ 50mm ~ 70mm is only 0.35 Kg ~ 0.7 Kg

Therefore, it is impossible to complete the demoulding by the weight of the iron alloy itself.

[0007] 3. Poor fluidity: Compared with ordinary molten steel and hot metal, the fluidity of ferroalloy is relatively poor, which is about one-third of the fluidity of molten iron. Appliances do not meet the requirements
