钢铁行业技术进步和产业升级将进一步释放优质产能，但严控新增产能的大形势不变，促使钢铁行业增加对环保和技术进步的投入，降本增效，优化产业结构，提升产品竞争力和附加值，通过技术进步提高产能将成为钢铁行业的发展方向。
The
technological progress and industrial upgrading of the steel industry
will further release high-quality production capacity, but the overall
situation of strictly controlling new production capacity remains
unchanged, prompting the steel industry to increase investment in
environmental protection and technological progress, reduce costs and
increase efficiency, optimize industrial structure, enhance product
competitiveness and added value, and improve production capacity through
technological progress will become the development direction of the
steel industry.
总之，现阶段钢铁行业的整体发展形势向好。但是，钢铁行业受原材料价格波动、政策效应、环保政策、国际贸易壁垒、下游产品供需、宏观经济发展等各方面综合因素影响较大，对此，业内各机构和专家对于钢铁行业良好的发展势头能否长久持续看法并不一致。无论如何，大多数钢铁企业都想抓住这波行情，因此，在严控产能情况下，相当一部分钢铁企业把目光投向那些能够迅速带来产能提高的技术上。其中，提高高炉富氧率是一个非常现实有效的办法。在刚过去不久的2017年，多家钢铁企业都选择提高自己的制氧能力，纷纷投资建设多套大型制氧机组，一种简单高效的制氧方式受到热捧，即变压吸附制氧技术。
In
short, the overall development situation of the steel industry is
improving at this stage. However, the steel industry is greatly affected
by various comprehensive factors such as fluctuations in raw material
prices, policy effects, environmental protection policies, international
trade barriers, downstream product supply and demand, and macroeconomic
development. Therefore, various institutions and experts in the
industry have different opinions on whether the good development
momentum of the steel industry can be sustained for a long time. Anyway,
most steel companies want to seize this trend, so while strictly
controlling production capacity, replacing outdated products with equal
quantities, a considerable number of steel companies are turning their
attention to technologies that can quickly increase production capacity.
Among them, increasing the oxygen enrichment rate of blast furnaces is a
very practical and effective method. In the recent year of 2017,
multiple steel companies chose to improve their oxygen production
capacity and invested in the construction of multiple large oxygen
production units. A simple and efficient oxygen production method,
namely pressure swing adsorption oxygen production technology, was
highly sought after.
