福州钢窗厂主要生产32系列窗框钢。由于生产的需要和机加工能力不足,在进行此系列产品试制中,没有沿用双联无芯万能轧机作为成品轧机,而是在带钢立辊轧机的基础上,设计试制了一台立辊传动的小型型钢万能轧机。生产实践表明,它能成批轧制合格的窗钢,获得 Fuzhou steel window factory mainly produces 32 series of window frame steel. Because of the need of production and the lack of machining capacity, in the trial production of this series of products, there was no follow-up of double coreless universal mill as finished mill, but on the basis of strip vertical mill, a vertical roller drive Of the small steel universal mill. Production practice shows that it can batch rolling qualified window steel to obtain
