电炉电热丝烧断后,可以用焊接方法接起来再用。具体焊接方法如下: 1.首先将电热丝烧断处两端分别拉直50～60mm(下图),并使其重叠。 2.用废电热丝作填充材料,用脱水硼砂作熔剂。 3.焊接时将两端夹牢,用小号气焊炬,氧乙炔中性焰焊接。重叠部分的两端各留出 Electric furnace heating wire blows, you can use the welding method then pick up and reuse. Specific welding methods are as follows: 1. First, the heating wire blown at both ends were straightened 50 ~ 60mm (below), and make it overlap. 2 waste electric wire for filling material, dehydration borax for flux. 3. When welding both ends of the clamp, with a small gas welding torch, oxyacetylene neutral flame welding. The two ends of the overlap are set aside
