Abstract
The invention relates to integrated equipment for preparing KR (Kanbara Reactor) desulfurizer. The equipment comprises a raw material receiving groove, an under-groove vibrating feeder, a raw material lifter, a raw material cabin, a raw material vibrating feeder, a belt conveyor, a jaw crusher, a pre-grinding lifter, an intermediate hopper, a mill vibrating feeder, a mill, a post-grinding lifter, screening equipment, mixed feeding equipment, prilling equipment, drying and straightening equipment, an aggregate crusher, a product limestone batch hopper, a lime electric clapper, a double-pipe stirrer, a fluorite electric clapper, a double-pipe and a product desulfurizer cabin. The invention further relates to a preparation method of the KR desulfurizer. The integrated equipment for preparing KR desulfurizer not only can produce the KR desulfurizer in a definite proportion, but also can recover active lime sieve residues and post-graded active lime fine powder, so that the utilization ratio of the active lime raw material is improved, the problem that ultrafine active lime needs to be conveyed outside is solved, and meanwhile, the comprehensive cost for preparing the KR desulfurizer is lowered and the environmental pollution caused by the ultrafine fine powder is reduced.
Description
technical field [0001] The invention relates to a KR desulfurizer preparation integrated equipment and preparation method, which are used in metallurgical industry and similar powder preparation industry. Background technique [0002] KR desulfurization is currently the most commonly used hot metal desulfurization method in China, and the consumption of desulfurizer is about 10kg / ton of hot metal. The desulfurizer is mainly composed of fluorite and active lime. The ratio of fluorite and active lime can be adjusted according to the composition of molten steel. Generally, the ratio is 1:9. [0003] Normally, the particle size of the fluorite powder and active lime powder used to prepare the desulfurization agent is controlled at about 0.5-1.0mm. A desulfurizer that is too fine is easy to burn and produce fly ash during the desulfurization process, which is harmful to the entire desulfurization process. [0004] The current desulfurizer preparation process will generally produ...
