我厂使用的一台RJT—140—9推杆炉,其发热元件为电阻带,炉顶电阻带的安装方式为波纹形悬挂布置。具体方法是:把φ10mm耐热钢辊(材料:1Cr18Ni9Ti)锯成一定长度,尺寸以炉型而定,一般以电阻带悬挂在最佳位置时电阻带上部到炉顶瓷管上端的距离再加130mm。然后在钢辊上端30mm处钻一个φ3mm的孔,用来穿支撑在瓷管上的销钉。在钢辊下端80mm处,把钢辊下端弯曲成L型(锐角),然后从炉膛内钩着波形电阻带,通过炉顶的瓷管,用
I use a factory RJT-140-9 pusher furnace, the heating element for the resistance zone, roof resistance zone installation of corrugated suspension arrangement. The specific method is: the φ10mm heat-resistant steel roll (material: 1Cr18Ni9Ti) sawed to a certain length, the size of the furnace may be, the general resistance band hanging in the best position when the upper resistance zone to the top of the furnace porcelain top plus 130mm. Then drill a φ3mm hole at the upper 30mm of the steel roller to wear the pin supported on the porcelain tube. The lower end of the steel roll at 80mm, the lower end of the steel roll bent into L (acute angle), and then hooked from the furnace with a corrugated resistance band, through the top of the porcelain tube with
