摘要
承钢的钒抽取转炉工艺是选择性氧化一氧化碳和钒的重要过程,该工艺的成功应用需要将终点温度稳定控制在1 380℃左右.在钒的抽取过程中,通过降低热金属的温度可以促进钒的氧化,并保持适当的碳含量.因此,在钒的抽取初期阶段,需要添加适量冷却剂以控制反应温度.重点研究了承钢的钒抽取工艺,并通过计算或测量冷却剂的比热,结合理论计算和差热扫描量热仪(DSC)实验,考察了不同温度的冷却剂对温度的冷却效果.通过这项研究可更好地理解钒抽取过程中冷却剂的作用机制,并为改善工艺的稳定性和效率提供科学依据.
Abstract
The vanadium extraction converter process of Chenggang is an important process for selective oxidation of carbon monoxide and vanadium.The successful application of this process requires stable control of the endpoint temperature at around 1 380 ℃.During the extraction process of vanadium,reducing the temperature of the hot metal can promote vanadium oxidation while maintaining an appropriate carbon content.Therefore,in the initial stage of vanadium extraction,it is necessary to add an appropriate amount of coolant to control the reaction temperature.The vanadium extraction process of Chenggang was studied in detail,and the cooling effect of different temperatures of coolant on temperature was investigated by calculating or measuring the specific heat of the coolant,combining theoretical calculations and differential scanning calorimetry(DSC)experiments.This study provides a better understanding of the mechanism of coolant in the vanadium extraction process and provides a scientific basis for improving the stability and efficiency of the process.
