Preparation system and method of KR desulfurizer

Abstract

The invention discloses a KR desulfurizer preparation system and method.The KR desulfurizer preparation system comprises a rubber belt conveyor, a crusher, a bucket elevator, a square reciprocating rotary screen, a collector, a fine powder bin and a roller press; a discharging port of the crusher is connected with a feeding port of the square reciprocating rotary screen through the bucket elevator, a first discharging port of the square reciprocating rotary screen is connected with a feeding port of the crusher, a second discharging port of the square reciprocating rotary screen is connected with a feeding port of the collector, and a third discharging port of the square reciprocating rotary screen is connected with a feeding port of the fine powder bin. A discharging port of the fine powder bin is connected with a feeding port of the roller press, and a discharging port of the roller press is connected with a feeding port of the crusher. According to the invention, the yield and the effective particle size rate of the KR desulfurizer are improved, the lime consumption is reduced, and the operation cost is reduced; the problem that dust generated in the screening process is large and does not meet the ultra-low emission standard is solved, and more environment friendliness is achieved; and a reference mode is provided for producing and preparing small-particle materials such as lime and the like.

Description

technical field [0001] The invention belongs to the technical field of iron and steel metallurgy, and in particular relates to a preparation system and method of a KR desulfurizer. Background technique [0002] Sulfur is one of the common harmful elements in steel, which has many adverse effects on the properties of steel. Sulfur in iron and steel metallurgy mainly comes from fuel and ore. Due to its harm to metal materials, desulfurization has become the primary task of the metallurgical industry. With the substantial update and improvement of iron and steel smelting technology and the continuous increase of production varieties, high-quality steel has higher and higher requirements for sulfur content, which puts forward stricter requirements for the desulfurization process. KR method desulfurization is a desulfurization method in the molten iron ladle by mechanical stirring. It is a desulfurization process with advanced technology, mature technology and low operating cost...
