上半年，物流与生产资料市场运行总体向好,二季度略好于一季度，主要体现在市场发展的稳定性与协调性增强。下半年，市场运行将延续平稳走势,发展的协调性进一步增强。全年社会物流总额可比增长9%左右，生产资料销售总额增长10%左右，能够支持宏观经济运行在合理适度区间。

作为钢材生产的原料，铁矿石价格变化对我国钢铁企业的经济效益产生重要影响，结合我国铁 矿市场现状，重点分析我国国内各品种钢材价格与进口矿、国产矿价格的关系。

2014年1-5月，我国生产粗钢34251.88万吨，同比增长2.71%，增幅较去年同期下降了5.28个百分点；钢材产量达45259.88万吨（含重复材），同比增长6.07%，增幅较去年同期下降了4.74个百分点。2014年5月份，我国钢材出口创单月出口历史新高807.14万吨，同比增长49.1%，环比增长7%，特别是热轧合金中厚宽钢带、冷轧不锈薄板、镀锌板带和其他热轧合金钢盘条的出口，均再创各品种单月出口历史新记录；而钢材进口环比则下降6.81%。5月，铁矿石进口环比下降7.2%，结束了连续两个月环比增长的趋势，进口平均单价已降至1年来的新低110.23美元/吨。5月焦炭出口创2010年以来单月出口新高99.43万吨，同比增长139.1%，环比增长113.8%.

钢联资讯08月25日消息，上海钢联举行钢铁电商平台发布会，首次向外界公开介绍上海钢银电子商务有限公司的交易模式和供应链整体解决方案。上海钢银是上海钢联投资控股的大型钢铁现货交易平台，旨在为产业链提供全流程解决方案，打造集现货交易、仓储物流、在线融资、支付结算及配套服务于一体的“无缝钢铁交易平台”。

8月份国内钢市整体弱势盘整。进入8月份，受经济数据大幅下滑等宏观政策层面利空的影响，钢材期货破位后连创新低，钢坯价格更是跌至8年来新低；8月上旬重点钢企粗钢日产和钢厂库存双双攀升，供给压力再次加大；受高温雨季及部分行业休假制约影响，下游需求低迷，钢材现货市场持续下跌，建材市场降幅较大。截止26日，省内市场三级螺纹钢价格2870-2890元/吨，较上月末下跌200元/吨；厚规格热卷价格3200-3260元/吨，较上月末下跌90元/吨；中板价格3150-3210元/吨，较上月末下跌80-120元/吨；H型钢中小规格价格3070-3100元/吨，普通大规格价格3060-3090元/吨，较上月末下跌20元/吨；45#钢价格3240-3270元/吨，较上月末下跌50-60元/吨。

2014年7月份，钢材价格指数较6月末小幅回落，再次创出历史新低；7月份钢铁行业累计固定资产投资同比维持下降态势；1-7月份我国生铁、粗钢和钢材产量均呈现环比下降，钢材产量小幅下降；粗钢产量占全球比重小幅回落，维持在50%的左右；7月份钢材出口量出现回升，外部钢材需求有所好转；进口量较上月有所回升。整体来看，7月份我国钢铁产量维持高位，供给压力仍然较大，需求情况仍然处于波动状态。

在当前钢铁行业产能过剩、铁矿石价格高、钢价持续走低的情况下，传统粗钢产品很难创造 利润，建设钢铁物流园就成为钢铁企业新的利润增长点，钢铁物流园的合理布局和建设将对钢铁物流业的发展起到积极作用。

Steel is the main engineering material used in the manufacturing process of the Construction, Automotive, Transport, Power, Mechanical Machinery, Metal Goods, and Domestic Appliances industries. It is also the main material used to deliver renewable energy such as solar, tidal, and wind. Steel is composed of iron, carbon, impurities, and alloying elements that determine its properties. Based on its properties, steel is classified into various types such as carbon steel, alloy steel, stainless steel, and tool steel. Steel provides various advantages to the products in which it is used such as strength, durability, corrosion resistance, hardening ability, formability, welding ability, and ductility.

by studying steelmaking-casting-rolling production process,a mathematical model of integrated batch planning is established innovatively to minimize processing costs of whole line and computed by an intelligent optimization ant algorithm.On the premise of utilizing and coordinating capacity of steelmaking and rolling,the mathematical model of integrated batch planning can create integrated batch planning to combine steelmaking-casting-rolling closely according to each process constraint conditions and optimization objective.Furthermore,another mathematical model of job scheduling based on heat process model is proposed to not only guarantee the logistics balance between continuous casting and hot rolling,but also acquire the highest ratio of DHCR and lowest energy consumption.
