鋼鐵業的鐵礦燒結製程
在低營運成本下獲得品質均一穩定的燒結礦
燒結礦是高爐煉鐵的主要材料。生產高品質燒結礦對於確保高爐穩定運作以及降低焦炭用量至關重要。獲得高品質的燒結礦從原料的合理選擇和混合開始。原料混合不均勻可能會影響穿透性並引起燃料消耗增加。
Thermo Fisher Scientific 為鋼鐵生產過程各環節提供先進的系統和設備，尤其是針對燒結製程測量和控制，協助改善混料不均勻和其他可能導致生產率下降、燒結礦物理和冶金品質下降以及原材料消耗量增加的因素。
Why sinter feed composition control matters
The production of high-quality sinter is crucial for assuring consistent, stable furnace productivity with a low consumption of reductants. Sinter quality begins with the proper selection and mixing of the raw materials. Inhomogeneous raw mix can affect permeability and cause an increase in fuel consumption.
Advanced technology to measure & control sintering process
Sinter feed composition control control is important because various sinter feed materials are not perfectly characterized and their chemical makeup varies within a batch and between batches.
As the raw feed material chemistry changes, the additive feed rates should be adjusted to smooth out these variations in the sinter strand feed chemistry.
The basicity of sinter feed material is an important parameter in the efficient operation of the sintering and iron making process. Basicity is a calculated chemical parameter composed of the ratio of two or more elements that are known to affect the alkalinity of the material. Stabilization of the basicity of the sinter product delivers benefits not only to the sinter operations but to the downstream iron making process.
Thermo Fisher Scientific’s CB Omni Online Elemental Analyzer can help control the sinter feed basicity and provide a more consistent feed to the sinter strand. The benefits of real-time chemical analysis data provided by the CB Omni analyzer include:
- More consistent sinter product—improves sinter quality and stabilizes feed to the blast furnace
- Increased sinter strand and blast furnace throughput due to reduced sinter product variability
- Decreased return fines lowers material handling costs
- Reduced load on laboratory, allowing capacity to be used elsewhere without incurring additional costs
- Net reduction in cost per ton of sinter production
