Embodiment Construction

[0051] Figure 1-Figure 9 It is a schematic diagram of the structure of the granulation casting machine and its components used in this preferred embodiment. The granulation casting method of this embodiment is realized by means of the granulation casting machine.

[0052] In this embodiment, the granulation casting method includes the following steps:

[0053] (1) Casting

[0054] Pour the liquid metal raw materials into the tundish 11 of the casting device 1. The liquid metal raw materials in the tundish 11 flow out from the discharge port of the tundish 11, and then flow into the casting pipe 13 below the discharge end of the casting pipe 13. The solidification molding device 2;

[0055] The solidification forming device 2 includes a crystallizer 22. The upper surface of the crystallizer 22 is provided with a plurality of forming grooves 24. The liquid metal raw material flowing out of the discharge end of the casting pipe 13 enters the respective forming grooves 24 on the upper su...

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 ...
