Fault Analysis and Solution of the Waste Acid Roasting& Regeneration System for Stainless Steel Pickling Lines 酸洗废液回收回用工艺技术研究不锈钢酸洗废酸焙烧再生系统故障分析与对策
The oxidation-reduction behaviour of organic matters in the course of oxidation roasting, acid leaching and alkali leaching, the regeneration of humic acid and the consumption of reagents are described in this paper. The mineralogical characteristics of the organic matter samples were studied. 本文研究了有机质在氧化焙烧、酸浸、碱浸过程中的氧化还原作用和腐植酸的再生及试剂消耗情况,对有机质试样进行了矿物学特性的研究。
At present, the raw materials of iron oxide needed for the production of high-grade soft ferrite materials are mainly from iron oxide powders by spray roasting of the regeneration hydrochloric acids in cold-rolled steel plants. 目前,软磁铁氧体材料制造企业所需要的氧化铁原料,主要来自钢铁厂冷轧酸洗盐酸再生过程中喷雾焙烧所产生的氧化铁粉。
