一、电梯导轨型钢的用途、特点及生产工艺电梯导轨型钢属异型断面型钢,经热轧制而成。广泛应用于高层建筑的电动楼梯中,可承受高、低速运行,安全、稳定、可靠。其特点是:①底部内腿斜度小。②底部与导向面垂直度精度高(垂直度误差≤40’)。③底部扭曲度小。④底部中间具有内凹。⑤底部公差尺寸精度高(底宽公差为;士l.5)。由于具有以上优点,其技术水平达到国际先进水平。替代了该产品的进口,节约外汇,并大量出口,为国家创汇。
First, the use of elevator guide rail profile, characteristics and production process Elevator guide rail profiled steel is a profiled section, made by hot-rolled. Widely used in high-rise building electric staircase, can withstand high and low speed operation, safe, stable and reliable. Its features are: ① bottom of the slope of the leg is small. ② the bottom of the guide surface with high accuracy (verticality error ≤ 40 ’). ③ bottom twist is small. The bottom of the bottom has a concave. ⑤ bottom tolerance size of high precision (bottom width tolerance; disabilities l.5). As with the above advantages, its technical level reached the international advanced level. Instead of importing the product, foreign exchange is saved and exported in large quantities to create foreign exchange for the country.
