强化大型高炉生产的基本环节是研究炉内气体动力学特性.核心问题是要不断地改善炉料的透气性和控制煤气流的分布.问题的基本解决有赖于研究过细精矿(-325网目)的烧结,粉末的筛除,以及大型高炉使用100%球团的远景和对焦炭质置的新要求等.在大型高炉上采用高压操作的必要性和迫切性,同时也是强化大型高炉的有力手段.因此,高压促进高炉大型化的发展.大型化高炉炉喉间隙的大小,对布料有很大的影响.有必要发展矮胖、多风口、适当小风口的炉型.
The basic part of strengthening large-scale blast furnace production is to study the gas dynamic characteristics of the furnace.The core problem is to continuously improve the gas permeability of the charge and to control the distribution of the gas flow.The basic solution to the problem depends on the study of the fine concentrate (-325 mesh) Sintering, screening of the powder, the prospect of using 100% pellets in a large blast furnace and the new requirements on the quality of coke, etc. The necessity and urgency of using high-pressure operation on a large blast furnace are also powerful tools for strengthening a large blast furnace Therefore, the high pressure to promote the development of large-scale blast furnace large blast furnace throat gap size has a great impact on the fabric it is necessary to develop stubborn, multi-tuyere, appropriate small tuyere furnace.
