一、前言播磨厂是1966年建成投产,采用ISP法的铅锌冶炼厂。自投产以来,以降低焦耗(焦炭成本占冶炼能源成本的70%)和提高锌生产率(扩大有效炉床面积及提高反应速度)为目标,进行了很多改进。本文主要介绍1983年的风口中心形状改造及1986年从风口喷入焦粉的生产情况。
I. Preface The grinding mill is put into operation in 1966, using the lead-zinc smelter ISP. Since its launch, many improvements have been made to reduce coke burden (coke cost accounts for 70% of smelter’s energy costs) and to increase zinc productivity (increase effective hearth area and increase reaction rate). This article mainly introduces the transformation of the shape of the tuyere center in 1983 and the production of coke powder from the tuyere in 1986.
