The study on direct reduction process of pellet containing carbon with the addition of Zn-Pb-bearing iron and steel plant dust shows that the reduction time and pellet basicity have obvious effect on the evaporation of lead and final metalliztion degree of pellet.The reduction temperature has significantl influences on the lead and zinc evaporation ratios and on final metallization degree of pellet.The optimum parameparameters obtained are reduction temperature of 1 250℃, reduction time of 25 minutes and pellet...

The study on direct reduction process of pellet containing carbon with the addition of Zn-Pb-bearing iron and steel plant dust shows that the reduction time and pellet basicity have obvious effect on the evaporation of lead and final metalliztion degree of pellet.The reduction temperature has significantl influences on the lead and zinc evaporation ratios and on final metallization degree of pellet.The optimum parameparameters obtained are reduction temperature of 1 250℃, reduction time of 25 minutes and pellet basicity of 0.9.

对钢铁厂含锌铅粉尘配碳球团直接还原工艺进行了研究.结果表明:生球碱度及还原时间对球团中铅挥发率和铁的金属化率有显著影响,而还原温度则对球团中锌、铅挥发率和铁的金属化率均有显著影响.在此基础上确定的最佳工艺参数为:生球碱度~0.9,还原温度和还原时间分别为1250℃和25min.

The effects of reduction temperature, coal size and coal amount on reduction rate of iron oxide in carbon-bearing pellets made from dusts containing zinc and lead are experimentally investigated in the atmosphere ofnitrogen and between 1 050~1 300℃. Results show that reduction temperature hassignificant effect on the reduction rate of iron oxide while coal sizeand amount of excess coal have no effect. The determined activation energyvaries with the temperature range and reduction degree. The rate-controllingstep...

The effects of reduction temperature, coal size and coal amount on reduction rate of iron oxide in carbon-bearing pellets made from dusts containing zinc and lead are experimentally investigated in the atmosphere ofnitrogen and between 1 050~1 300℃. Results show that reduction temperature hassignificant effect on the reduction rate of iron oxide while coal sizeand amount of excess coal have no effect. The determined activation energyvaries with the temperature range and reduction degree. The rate-controllingstep for reduction of iron oxide is determined based on the analysis ofactivaton energy and the kinetic models describing the reduction of iron oxide.

在氮气气氛和1050~1300℃温度范围内,采用化学分析方法研究了还原温度、过量碳及煤粉粒度对含锌铅粉尘配碳球团中氧化铁还原速率的影响.结果表明:还原温度对氧化铁还原速度有显著影响,过量碳和煤粉粒度对还原速率没有影响.在不同还原程度和还原温度下,得出了氧化铁还原的表观活化能,由活化能结果和还原动力学模型对实验结果进行分析,确定了氧化铁在不同还原程度和还原温度下的还原限制性环节.

Based on the success of laboratory experiments,semi-industrial experiments,which used aluminium bath smelting reduction,were carried out for separating Zn-Pb in Zn-Pb-containing dusts of steelmaking plant.The experimental results indicate that using aluminium bath smelting reduction to treat Zn-Pb-containing dusts can directly get higher level ZnO-powder by single-step process.The economic profitability for the process is also analized.
