一、前言近年来,随着高炉冶炼技术的发展,对作为主要炉料的烧结矿,提出了更应具有良好冶金性能和满足高炉熟料率的需求。国外烧结技术的发展在探索新的工艺、设备、方法上有所创新,并取得一定成效。本文对以下几方面作一些介绍,供国内同行借鉴:①烧结布料技术的新发展;②采用富氧烧结法;③双层烧结新工艺;④继续推行高料层技术;⑤高还原性烧结矿的生产。二、烧结布料技术的新发展烧结机上的混合料的结构必须具有一定特性:保持良好的孔隙度和大的料层比表面。准备得很好的料层孔隙率是0.42～0.49。这种料层结构是微弱的,当风箱负压为5
I. Introduction In recent years, with the development of blast furnace smelting technology, the demand for sinter ore, which is the main charge, should have better metallurgical properties and meet the requirement of blast furnace clinker rate. The development of foreign sintering technology in the exploration of new technology, equipment, methods, innovation, and achieved some success. This article introduces some of the following for domestic counterparts: ① new developments in sintering technology; ② oxygen-rich sintering method; ③ double-layer sintering process; ④ continue to promote high-layer technology; ⑤ high-reduction sinter Production. Second, the new development of sintering cloth technology The structure of the mixture on the sintering machine must have certain characteristics: to maintain good porosity and large surface area ratio. Well-prepared material porosity is 0.42 ~ 0.49. This material structure is weak, when the bellows negative pressure of 5
