钳口是把钢锭送入加热炉和取出重20吨、温度1260—1280℃赤热钢锭夹钳起重机的主要工作元件。在使用过程中,由于钳口常常遇热到高温(在运送钢锭时),并在空气和水中冷却。因此,工作表面被强烈地磨损,使钳口迅速报废。为了选择堆焊材料及拟制工艺方案和规 Jaw is the ingot into the furnace and remove the weight of 20 tons, the temperature 1260-1280 ℃ red hot ingot clamp crane’s main working components. During use, the jaws often experience heat to high temperatures (during ingot delivery) and are cooled in air and water. As a result, the work surface is strongly worn, causing the jaws to quickly scrap. In order to choose the welding materials and the proposed process planning and regulation
