选择了国内通用的单丝埋弧焊成熟技术堆焊连铸辊。通过实验室对比了15CrMo辊芯母材和堆焊金属的性能,选择并优化了堆焊工艺参数,使堆焊的连铸复合辊实物水平达到了企业内部技术条件。经工业装机试验表明,堆焊的连铸复合辊较15CrMo普通连铸堆焊辊使用寿命提高3～6倍。
Choose the common domestic single-wire submerged arc welding technology of surfacing continuous casting roller. Through comparing the properties of 15CrMo core metal and surfacing metal in laboratory, the parameters of surfacing welding were selected and optimized, and the solid state of surfacing composite roll met the internal technical conditions of the enterprise. After the industrial installation test shows that the surfacing of the continuous casting composite roller 15CrMo ordinary cast-iron surfacing roller life increased by 3 to 6 times.
