<p><p>据新市场报告，近一周，国内镀锌方管价格综合指数报收于135.98点，一周下跌2.58%。目前，镀锌方管价格继续整体回落，市场“追高不追跌”，下游采购谨慎，而钢贸商却急于出货，价格不断松动，但总体成交平淡。虽说目前尚处于传统的消费旺季，但市场的看涨信心与接货意愿相对不足。据分析，在建筑钢市场上，价格出现不同程度的下跌。局部一周吨价跌幅均超100元。在局部市场可以看到，镀锌方管价格在走低，镀锌方管价格也在回落，市场“看空”氛围再度加强。主导镀锌方管厂的新出厂定价虽然还在表现强势，但相对较弱的需求是抑制价格实际走势的重要因素。在板材市场上，价格总体下跌。热轧板卷价格出现不同程度的下跌，其中场价格的周跌幅为240元，居于。在一些地区，市场心态偏弱，部分商家有“抛货”的现象。一些成交尚可，但总体接货不畅，下游多按需采购。中厚板价格止涨返跌，局部地区吨价一周下跌超过100元。市场的观望情绪浓厚，需求持续减弱。<br/><img src="http://oss11.huangye88.net/live/2024/07/26/44e2257a6448cb54a77c28e350837da3.jpg@750w_750h_90Q" /><br/>这是因为压力，作为过剩行业热镀锌方管，钢铁业在资金等法规方面都属于受限制的行业，即便近期央行连续两次定向降准支持实体经济，钢铁行业或也很难从中直接获益。更何况，“微”法规的显现和效果传导至钢铁市场均需要时间。但因目前我国热镀锌方管行业供需矛盾严重失衡，而从近几年价格走势的特点可以得出，往往大宗钢材价格上涨结束进入下行，价格才缓慢跟进，这种滞后性严重打压了热镀锌方管行价格的上涨幅度。<br/><img src="http://oss11.huangye88.net/live/2024/07/26/63d70add6c8d1400411c0586e2b1d2d0.jpg@750w_750h_90Q" /><br/>根据CCI动力煤价格指数，在2019年年底国内动力煤价格非理性上涨的时候，进口煤的价格优势开始扩大；春节前夕，国内动力煤价格高位回落，内外价差收窄；春节之后，海外动力煤价格跟随下跌，目前进口煤相比内贸煤的价格优势再一次扩大。加上进口煤通关效率提高，所以我们预计3月份进口动力煤数量将继续增加。<br /> <br /> 近日有传言称，从今年3月24日开始，二类口岸将再次禁止进口煤炭。这是2019年已经实施过的限制措施，相当于保供任务结束之后，针对进口煤的限制措施恢复常态。消息尚未得到证实，根据去年的情况，如果确定全面禁止，可能每月会影响200万吨左右的进口量。不过，由于已有前车之鉴，我们认为该因素对市场的影响力度不会很大。<br /> <br /> 方管性能<br /> 塑性<br /> 塑性是指金属材料在载荷作用下，产生塑性变形（变形）而不破坏的能力。<br /> 硬度<br /> 硬度是衡量金属材料软硬程度的指针。目前生产中测定硬度方法常用的是压入硬度法，它是用一定几何形状的压头在一定载荷下压入被测试的金属材料表面，根据被压入程度来测定其硬度值。<br /> 常用的方法有布氏硬度（HB）、洛氏硬度（HRA、HRB、HRC）和维氏硬度（HV）等方法。<br /> 疲劳<br /> 前面所讨论的强度、塑性、硬度都是金属在静载荷作用下的机械性能指针。实际上，许多机器零件都是在循环载荷下工作的，在这种条件下零件会产生疲劳。<br /> 冲击韧性<br /> 以很大速度作用于机件上的载荷称为冲击载荷，金属在冲击载荷作用下抵抗破坏的能力叫做冲击韧性。<br /> 强度<br /> 强度是指金属材料在静荷作用下抵抗破坏（过量塑性变形或断裂）的性能。由于载荷的作用方式有拉伸、压缩、弯曲、剪切等形式，所以强度也分为抗拉强度、抗压强度、抗弯强度、抗剪强度等。各种强度间常有一定的联系，使用中一般较多以抗拉强度作为基本的强度指针。<br /> <br /> C下游电煤库存快速增加<br /> <br /> 在供给端——煤矿生产和煤炭进口积极增量的同时，动力煤需求开始逐步从消费旺季向消费淡季过渡，双重改变之下，动力煤市场供需格局加速扭转，港口及下游电厂煤炭库存得到修复，市场看空情绪增强，共同促使动力煤价格大幅走低。<br /> <br /> 春节以来，铁路总公司积极配合保供应政策，大秦线等主要运煤通道维持较高装运水平，确保产地煤炭至港口的周转顺畅，使得港口煤炭库存恢复上涨。截至3月23日，秦皇岛港煤炭库存增至662万吨，曹妃甸港煤炭库存增至337万吨，黄骅港煤炭库存增至238.5万吨。<br /> <br /> 下游电厂煤炭库存增加幅度更大。春节期间，对于沿海地区主要电厂来说，不论是实际的电煤库存数量，还是存煤可用天数，增加。尤其是沿海电厂的日耗回落至50万吨/天以下，带来了存煤可用天数的快速攀升。春节假期结束之后，沿海电厂累库速度进一步加快，2月底沿海电厂合计煤炭库存已经增至7万吨，为近年来高位。<br /> <br /> 3月中下旬，配合沿海市场煤炭运价的走高，沿海电厂合计煤炭库存再度创出2014年9月以来的新高，至1463.5万吨；存煤可用天数稳定在22天左右。这样高的库存水平给予电厂议价的底气，很快市场煤价格跌到比长协煤更便宜的价位。<br /> <br /> 3月初，大型煤炭企业5500大卡动力煤的月度长协价较月下跌18元/吨至677元/吨，年度长协价较月下跌2元/吨至5元/吨，当时秦皇岛港5500大卡动力煤的市场价报684元/吨。然而，截至3月23日，秦皇岛港5500大卡动力煤的市场价已经跌至627元/吨。新消息称，神华集团通知客户，3月15日前离泊的动力煤参照1—15日CCI均价661元/吨结算，后半月部分参照16—31日CCI均值结算，这相当于下调了3月份长协动力煤的综合结算价格。<br /> <br /> 尽管动力煤价格大幅下跌，但是下游电厂已经完成补库过程，短期内继续采购的积极性将显著下降。终端需求的下降，很快自下而上传导至产地坑口，煤矿销售出现不畅，坑口拉煤车辆减少，部分煤矿库存有积累迹象，后续有继续降价的计划。<br /> <br /> 季节性规律显示，由于冬季消费高峰结束，且水力发电量逐渐增加，接下来的4—6月，沿海电厂日耗一般持稳或下降。所以，后续下游电厂也难以出现新的补库需求，直到夏季煤炭消费高峰到来。</p></p> </div> <div class="product-sort"> <p>所属分类：<a href="http://yejin.huangye88.com/gangcai/"
