吉林冶金机电设备制造厂生产的国产化第一条双线速冷钢管热镀锌生产线机组于去年10月在广西玉林市钢管厂一次试车成功,所生产的镀锌管符合国家标准.其总造价仅是进口的1/6左右.该设备自动化程度高,适用范围广,镀锌质量稳定,生产效率高,耗电量低,锌锅具有保温效果好,易维护等优点.原进口设备的配重体系是由圆周运动的配重去平摆动的摆臂,效果差,驱动摆臂的电机减速机及摩擦制动离合器经常损坏、寿命短,严重影响正常生产.该厂经过对原机构的力学分析,变配重圆周运动为摆动,彻底改变了原配重体系和受力状态,降低了减速机输出轴的回转冲击,延长了该驱动系统的电机减速机及电磁离合器使用寿命.镀锌加热炉是全线的主要设备,在吸收了进口生产线工艺的先进性基础上,采用了国产电阻带立绕挂在耐热框架上置于锌炉两侧,保温层采用双层硅酸铝耐火纤维材料,热效率高,保温效果好,耗电量低于进口设备10%.锌炉温控采用调功率方式,由计算机采集温度、功率、时间曲线,经内部整定参数后,可实现全自动调节锌液温度的功能,温度控制精度达土2℃,提高了镀锌质量.
Jilin metallurgical machinery and equipment manufacturing plant production of the first two-wire rapid cooling hot dip galvanized steel production line unit in October last year, Yulin City, Guangxi steel pipe plant a successful trial, the galvanized pipe produced in line with national standards. The total cost Only imports about 1 / 6. The high degree of automation equipment, a wide range of applications, galvanized quality and stability, high efficiency, low power consumption, zinc pot has a good insulation effect, easy to maintain, etc. The advantages of the original imported equipment Heavy system is the swinging arm swinging by the weight of the circular motion, the effect is poor, the motor reducer and the friction brake clutch that drive the swing arm are often damaged, and the service life is short, seriously affecting the normal production. Analysis, variable weight circular motion for the swing, completely changed the original weight system and the force state, reducing the output shaft reducer rotary impact, extending the drive system of motor reducer and electromagnetic clutch life. Galvanized heating furnace Is the main equipment across the board. Based on the advanced technology of imported production line, the domestic resistance band is used to hang around the heat-resistant frame on both sides of the zinc furnace. The thermal insulation layer is made of double-layer aluminum silicate Fire fiber material, high thermal efficiency, thermal insulation effect is good, power consumption is lower than 10% of imported equipment.Zinc furnace temperature control using power adjustment mode, by the computer to collect temperature, power, time curve, the internal tuning parameters can be fully automatic Adjust the temperature of zinc liquid function, temperature control accuracy of soil 2 ℃, improve the quality of galvanized.
