Description
技术领域 technical field
本实用新型涉及冶金技术领域，特别是一种400系列不锈钢除尘灰综合利用系统。 The utility model relates to the technical field of metallurgy, in particular to a 400 series stainless steel dust removal comprehensive utilization system.
背景技术 Background technique
目前国内外处理不锈钢除尘灰的技术相对较多，按回收装置分类大致有：转底炉技术、竖炉技术、等离子炉技术、矿热炉技术以及电炉技术等。转底炉技术、竖炉技术、等离子炉技术投资大、技术难度也大，在当前钢铁业不景气的情况下恐怕短时间内难以实现。矿热炉技术由于电耗太高，其加工成本较传统的烧结-炼铁成本高很多，而且只能为不锈钢系统提供含铬生铁块，导致其含铬铁水的热能不能得到有效利用。电炉技术存在配用比例受限，400系列除尘灰消化不完等问题。 At present, there are relatively many technologies for processing stainless steel dust at home and abroad. According to the classification of recovery devices, there are roughly: rotary hearth furnace technology, shaft furnace technology, plasma furnace technology, submerged arc furnace technology and electric furnace technology. Rotary hearth furnace technology, shaft furnace technology, and plasma furnace technology require a lot of investment and technical difficulty, and may be difficult to realize in a short period of time under the current downturn in the steel industry. Due to the high power consumption of submerged arc furnace technology, its processing cost is much higher than that of traditional sintering-ironmaking, and it can only provide chromium-containing pig iron blocks for stainless steel systems, resulting in the ineffective use of the heat energy of its chromium-containing molten iron. The electric furnace technology has problems such as limited proportion and incomplete digestion of 400 series dust removal ash.
酒钢不锈钢400系列除尘灰中含有37%左右的铁氧化物、10%左右的铬，其中的铬的氧化物如果不经处理直接排放，会对环境造成污染，而且造成资源浪费。对于400系列除尘灰的利用主要通过压球后在不锈钢三脱、转炉和电炉工艺过程回收利用，但年平均回收利用率只有40%-45%，每年仍有1万余吨的400系列除尘灰积存，造成较大环境污染压力。 JISCO stainless steel 400 series dust contains about 37% iron oxide and about 10% chromium. If the chromium oxide is discharged directly without treatment, it will pollute the environment and cause waste of resources. The utilization of 400 series dust removal ash is mainly recycled in the process of stainless steel triple removal, converter and electric furnace after briquetting, but the annual average recycling rate is only 40%-45%, and there are still more than 10,000 tons of 400 series dust removal ash every year Accumulated, resulting in greater pressure on environmental pollution.
实用新型内容 Utility model content
本实用新型的目的在于提供一种回收利用率高、加工成本低的400系列不锈钢除尘灰综合利用系统。 The purpose of the utility model is to provide a 400 series stainless steel dust removal comprehensive utilization system with high recycling rate and low processing cost.
本实用新型解决其技术问题所采用的技术方案为： The technical scheme that the utility model solves its technical problem adopts is:
一种400系列不锈钢除尘灰综合利用系统，包括烧结机组，烧结机组分别与高炉组和小高炉的进料端连接，高炉组的出料端与碳钢加工车间连接；所述小高炉的进料端还与副烧结机连接，小高炉的出料端与不锈钢加工车间连接。 A 400 series stainless steel dust removal comprehensive utilization system, including a sintering unit, the sintering unit is respectively connected to the blast furnace group and the feed end of the small blast furnace, and the discharge end of the blast furnace group is connected to the carbon steel processing workshop; the feed end of the small blast furnace The end is also connected with the auxiliary sintering machine, and the discharge end of the small blast furnace is connected with the stainless steel processing workshop.
本实用新型将碳钢加工和不锈钢加工组合在一起，生产普通碳钢时，烧结机组工作并将烧结物料导入高炉组，再将钢水导入碳钢加工车间生产碳钢。生产不锈钢时，烧结机组工作并将烧结物料导入小高炉，副烧结机烧结不锈钢400系列除尘灰配入小高炉，最后将含铬钢水导入不锈钢加工车间加工不锈钢。本实用新型将碳钢加工和不锈钢加工组合在一起，不锈钢400系列除尘灰用于不锈钢加工系统后的回收利用率高，使除尘灰中铬的有效价值得以充分利用，系统生产效率高且加工出的不锈钢成本低廉，具有更好的市场竞争力。 The utility model combines carbon steel processing and stainless steel processing. When producing ordinary carbon steel, the sintering unit works and guides the sintered material into the blast furnace group, and then guides molten steel into the carbon steel processing workshop to produce carbon steel. When producing stainless steel, the sintering unit works and imports the sintered material into the small blast furnace, the auxiliary sintering machine sinters stainless steel 400 series dust and mixes it into the small blast furnace, and finally imports the chromium-containing molten steel into the stainless steel processing workshop to process stainless steel. The utility model combines carbon steel processing and stainless steel processing together, and the recycling rate of stainless steel 400 series dust removal ash is high after being used in the stainless steel processing system, so that the effective value of chromium in the dust removal ash can be fully utilized, the system production efficiency is high and the processed The cost of high-quality stainless steel is low and has better market competitiveness.
