蒸呢机市场价格跌幅收窄。近期由于期货以及钢坯下跌影响，市场心态普遍较为低落，今日开盘，各区域蒸呢机厂家报价依旧下调，邯郸武安、江阴下调10元；天津、唐山下跌20元；不 过，整体下调幅度较昨日均有小幅收窄。目前北方蒸呢机厂开工基本继续高位运行，产量未有明显减少，且近日市场成交低迷，蒸呢机厂家交投氛围不活跃，以致社会库存有 小幅增加，略微加大了出货压力。宏观因素来看，国内经济压力依旧较大，虽国家积极出台新政促进各行业指数回升，但从市场反应来瞧，影响不够显著。另外，国 内钢市淡季迎来，在市场需求萎缩，价格下滑，开工依旧高位的情况下，供强续弱的现象显现，与此同时钢企价格在坚挺中下调，即将接近成本线，其利润空间明显 收窄，整体看来，市场承压下行的趋势或将持续，不过，在成本支撑下，或还存在些许支撑，但随着价格阴跌，仍需警惕大幅下跌风险。
The market price declines narrowed. Recently, due to the impact of futures and billet declines, the market mentality is generally relatively low. At the opening of the market today, the quotations of local regulators are still down, Handan Wuan and Jiangyin are down by 10 yuan; Tianjin and Tangshan are down by 20 yuan; however, the overall decline is slightly narrower than yesterday. At present, the Northern Pipe Factory has basically continued to operate at a high level, and its output has not decreased significantly. In recent days, the market turnover has been depressed, and the trading atmosphere of the Pipe Factory has been inactive. As a result, the social stock has increased slightly, and the pressure of shipment has increased slightly. Macroscopic factors, the domestic economic pressure is still large, although the state actively introduced a new policy to promote the recovery of industry indices, but from the market reaction, the impact is not significant enough. In addition, the domestic steel market is coming in the off-season, when market demand is shrinking, prices are falling and construction is still at a high level, the phenomenon of supply continuing to be weak appears. At the same time, steel enterprises'prices are declining in a firm way, approaching the cost line, and their profit margins are obviously narrowed. On the whole, the downward trend of market pressure may continue. However, under the support of cost, there may still be some expenditures. Supporting, but as prices slump, we still need to be vigilant against the risk of a sharp fall.

蒸呢机和高效蒸呢机冷弯成型时不同的特点蒸呢机冷弯蒸呢机、冷弯高效蒸呢机是通过外辊与管坯外壁的单向接触形成弯矩使带料弯折,冷弯会使弯折线产生压缩,压缩效应使弯折线纵向伸长,弯折处金属出现堆积变厚,这就是冷弯的压缩/增厚效应。Cold-formed square pipe and cold-formed rectangular pipe bend the strip through the unidirectional contact between the outer rol… 厂家如何防止Q345B蒸呢机焊接的时候变形？…蒸呢机变形首先是焊接Q345B蒸呢机的焊接应力的存在的问题，蒸呢机加工时刻及加工机械节省 因为精度精确，外表状况良好，冷拉钢商品可直接运用，如喷涂、打砂，折弯，钻孔也可按实践需求精拉以后直接电镀，免去了很多加工。 如果想降低变形量或达到理想的尺寸误差范围，首先就焊接时的工件的工装及焊接顺序是必须的，每个焊接完的工…
