摘要

通过中试规模烧结杯试验和综合烧结模型，将返矿平衡和非平衡条件相结合，研究了混合料特性（烧结碱度、焦炭和水分添加量）对火焰烽面特性和烧结性能的影响机理。模拟研究涉及多种烧结条件下的125个烧结杯工况。为揭示火焰烽面区域中熔体生成与凝固行为，使用FactSage软件进行化学热力学模拟并建立了更完善的熔化和凝固子模型。模拟与试验研究表明，随着碱度和焦炭添加量的变化，火焰烽面速度、成品率、焦比和利用系数会出现局部最大或最小值。在本文烧结条件下，最大利用系数工况为碱度2.0、水分7.7%、焦炭6.4%。最小焦比工况为碱度2.0、水分6.5%、焦炭6.4%。最小焦比和最大利用系数的条件并不相同，而最终烧结操作取决于每个烧结厂的控制目标。

Abstract

In this paper

the pilot-scale sintering cup test and the comprehensive sintering model were combined to analyze the effects of mixture characteristics (sintering alkalinity

coke and moisture addition) on flame kneading properties and sintering properties. Previously developed and validated sintering sub-models have been integrated in this work. Simulations were carried out based on 125 cases simulating a wide range of sintering conditions. Thermochemical modelling using FactSage provided useful information to improve the melting and solidification sub-model and provide greater insights into the state of the material in the flame front. Modelling studies showed that the maximum or minimum values of flame front speed

yield

coke rate and productivity appear when the basicity and coke addition change continuously. Under the sintering conditions of present work

the condition for maximum productivity is basicity 2.0

moisture level 7.7%

coke level 6.4%. The condition for minimum coke rate is basicity 2.0

moisture level 6.5%

coke level 6.4%. Obviously

the optimum productivity and coke rate conditions are different. The actual operating conditions will depend on the objective of a sinter plant.
