Granulation machine for casting smelting molten iron of iron alloy series products into granular products

Abstract

The invention relates to a granulation machine for casting smelting molten iron of iron alloy series products into granular products. The granulation machine comprises a base, a cooling mechanism, a casting and forming mechanism, a turning-over and resetting mechanism and a center power device. A circle of track is arranged on the top of the base. The cooling mechanism is installed on the track ina sliding manner. The casting and forming mechanism is installed on the cooling mechanism in a manner of being capable of rotating up and down. The center power device drives the cooling mechanism and the casting and forming mechanism to do circumferential motion along the track synchronously. The cooling mechanism provides cooling water for the interior of the casting and forming mechanism so that molten iron on the casting and forming mechanism can be cooled and formed into the granular productions. The turning-over and resetting mechanism turns over the casting and forming mechanism up anddown after the granular productions are formed. The granulation machine solves the problems that a casting mould is ablated or cracked easily and is short in service life, and automatic molten iron casting, demoulding and forming of the iron alloy series smelting products are achieved.

Description

technical field [0001] The invention relates to the field of ferroalloy production, in particular to a granulator for smelting molten iron and casting ferroalloy series products into granular products. Background technique [0002] Casting templates are used for ferroalloy casting. After the molten iron is poured, it is necessary to wait for the molten iron to cool and solidify before the casting can be released. If it is cooled by blast, the time is long, the casting template is severely damaged by heat and the service life is short; if it is cooled by spraying, the casting template is easy to crack and damage. [0003] Ferroalloy casting is continuous casting, including casting, cooling, and demolding. The production cycle is long, the amount of casting templates is large, and the equipment is large. [0004] The existing ferroalloy continuous casting machines in the industry are arranged in a long shape and cooled by blowing air or spraying. The focus of improvement is t...
