Granulating and casting method

Abstract

The invention discloses a granulating and casting method. The granulating and casting method comprises the following steps that (1)casting is conducted, a liquid metal raw material is poured in to a tundish of a casting device, and flows into a solidification forming device below the discharging end of a casting pipe through the casting pipe; the liquid metal raw material flowing out of the discharging end of the casting pipe enter into forming grooves of a crystallizer in the solidification forming device; (2) solidification forming is conducted, after the liquid metal raw material in the to-be-formed grooves is solidified and formed, solidified and formed casting forming products are enabled to be separated from the crystallizer, and the casting forming products separated from the crystallizer fall into a material receiving and conveying device below the crystallizer; and (3) material receiving and screening is conducted. By adopting the granulating and casting method, casting and forming is conducted, the obtained products are relatively uniform in particle size, the production efficiency is high, waste materials such as dust generated in the production process are less, on onehand, waste can be reduced, and on the other hand, pollution to the environment can be reduced.

Description

Technical field [0001] The invention relates to a casting molding method, in particular to a granulated casting method. Background technique [0002] At present, the main casting method of industrial silicon, ferroalloy and other materials is cast iron ingot mold casting. This method uses multiple sets of fixed cast iron ingot molds to pour liquid metal raw materials (such as industrial silicon water or iron alloy water) into the cast iron ingot mold. Medium cooling, followed by manual cleaning, manual crushing, manual secondary crushing (or jaw crushing) and other processes to complete. Due to the small output of a single ingot mold, a very large number of ingot molds are required, and a large area is required; a lot of manual or machine crushing is required in the follow-up, and the dust rate is high, the product specifications after crushing are different, the particle size does not meet the requirements, and the workers Shortcomings such as high labor intensity and low work ...

AI Technical Summary

Problems solved by technology

Due to the small output of a single ingot mold, a very large number of ingot molds are required, which covers a large area; subsequent manual or machine crushing is required, resulting in high dust rates, different specifications of crushed products, particle sizes that cannot meet the requirements, and workers High labor intensity, low work efficiency and other shortcomings, and will cause a lot of waste

In addition, the cast iron ingot mold has a short service life and needs to be replaced frequently, which increases the cost
