烧结生产简介 Brief introduction of Sintering 一、烧结生产在钢铁工业中的地位和作用 1、什么叫烧结？ What is sintering? 生产人造块矿的方法：烧结法和球团法。 Ways of making agglomerate materials: sintering and pelletizing. 所谓烧结，就是将各种粉状的含铁原料，配入一定数量的燃料和溶剂，均匀混合，然后放在烧结设备上点火烧结。在燃料产生高温和一系列物理化学反应的作用下，混合料中部分易溶物质发生软化和熔化，产生一定数量的液相，并润湿其它未熔化的矿石颗粒，在冷却过程中，液相将矿石颗粒粘结成块，这个过程就叫烧结。所得的块矿成为烧结矿。 Put the powder material which contains Fe, together with amount of fuel and flux, mix them and put them on sintering equipments. After the burning of high temperatures and the chemical and physical reaction, some eutectic in the mixture will be softened or be melted, and amount of liquid phase comes out to wet other ore granules which are not be melted, during the cooling process, liquid phase make other ore granules into lumps, this process is called sintering. And the lump ores got from this process is called sintered ores. 2、烧结生产在钢铁生产中的地位和作用 随着钢铁工业的发展，天然含铁富矿从数量和质量上都不能满足高炉冶炼的需要，而大量含铁贫矿和多金属共生矿经选矿获得的高品位铁精矿和富矿粉不能直接入高炉冶炼，通过人造块矿方法解决了这一问题。 2．Importance of sintering in iron and steel making. Together with the improvement of steel industry, the quantity and quality of crude rich ore are not sufficient for the blast furnace, after separation processing of low grade ore and polymetallic ore to get high grade of concentrate and rich ore, most of them can not be used directly into blast furnace, but because of man-made lump ore, this problem is solved. 通过人造块矿过程，可以改进炼铁原料的物理化学性能，如粒度组成、孔隙率、机械强度、化学成分、还原性、高温冶炼性能等，从而强化高炉冶炼过程，促进高炉优质、高产、低耗。 Through out the process of man-made lump ore, the chemical and physical character will be improved, for instance, grading fraction, porosity, mechanical strength, chemical analysis, reducibility, and pyrolytic smelting character etc, in this sense, the process of blast furnace smelting will be strengthened, and the production of blast furnace will be high quality, high yield and low waste. 烧结过程，可以充分利用钢铁工业生产中的副产品，如高炉灰、轧钢皮、钢渣，起到资源综合利用，降低成本、净化环境的作用。 Sintering can also make full use of by-product like flue dust, mill scale and slag,
