与我厂联营的一家小轧钢厂,专业生产各种规格的小型扁钢。轧机为二辊开口式四架热连轧机。总动力为10、7.5kW交流电机各2台,全部单独驱动。原料为φ9mm盘圆,9～14mm方坯,主要是轧制φ6.5mm线材。产品规格为2～6×12～25mm的扁钢。从设计、施工至投入批量生产,仅用25天时间,投资近3万元。投产近一年来,已生产各种规格的小扁钢500余吨,不仅用于建筑钢窗的直条和波形条,商店银行的栅门,自行车座垫的固定环,还可用于儿童小车的原料。投产三个月,就收回全部投资,工厂和社会效益都较明显。 1.连轧常数计算的正确性,直接决定了机时产量四架跟踪式微型热连轧生产系统,全部由交流电机单独驱动,经皮带轮一级、齿轮二级变速,成品出口线速度为0.277m/s。电机、皮带轮、齿轮的主要技术参数如表1所示。轧辊尺寸及转速、轧件尺寸、堆拉率、连
A small steel mill affiliated with our factory specializes in producing all kinds of small flat steel. Rolling mill for the two open four hot tandem rolling mill. The total power of 10, 7.5kW AC motor 2, all driven separately. Raw materials for φ9mm round, 9 ~ 14mm billet, mainly rolling φ6.5mm wire. Product specifications for the 2 ~ 6 × 12 ~ 25mm flat steel. From design, construction to put into mass production, only 25 days time, nearly 30,000 yuan investment. Put into production nearly a year, has produced a variety of small flat steel more than 500 tons, not only for the construction of steel windows straight and the waveform bar, the gate of the store bank, bicycle seat cushion ring can also be used for children’s car raw material. Put into operation three months, to recover all the investment, factories and social benefits are more obvious. 1. Rolling constant calculation accuracy, directly determines the machine output Four trace-type mini hot-rolling production system, all driven by the AC motor alone, the pulley level, the gear two-stage speed, the finished export line speed of 0.277 m / s. The main technical parameters of the motor, pulley and gear are shown in Table 1. Roll size and speed, rolling size, heap rate, with
