我国的焊管机组已有800套,但是由于坯料不足及需求的疲软,产量不到设备生产能力的1/3,与之配套的后道工序——热浸镀锌机组,国内也有约几十套,目前存在以下主要问题。 1 主要问题①盲目发展与引进设备,而坯料不足造成普遍开工率不高。②质量不过关。包括坯料材质与焊管加工两方面,前者影响了生产高强度的锅炉钢 China’s welded pipe unit has 800 sets, but due to the lack of billets and weak demand, the production capacity of less than 1/3 of the production capacity, and its accompanying downstream processes - hot-dip galvanizing units, there are about dozens of sets , There are currently the following major issues. 1 The main problems ① blind development and the introduction of equipment, while the lack of billets caused widespread operating rate is not high. ② quality, however off. Including the billet material and pipe processing, the former affected the production of high strength boiler steel
