爆炸复合技术是通过炸药爆炸对复板进行加速，使其高速撞击基板，使两板实现结合的一种焊接加工方式。水下爆炸复合技术将爆炸复合装置置于水下，利用水取代空气作为爆轰能量的传播介质，实现对两板的复合。
值得注意的是，传统的空气中爆炸复合及轧制技术难以满足这种特殊复合材料的加工需求。当复板厚度≤2mm时，在空气中爆炸复合往往会遇到复板断裂、表面烧蚀及结合率下降等问题。相比之下，水下爆炸复合技术在此类薄板复合上展现出了显著优势，能实现的最薄复合厚度达到0.1mm，且过程更为稳定可靠，此外，还大幅降低了噪声与污染物排放。 Explosive composite technology is a kind of welding processing method in which the cladding plate is accelerated by explosive explosion to make it hit the substrate at high speed and combine the two plates. The underwater explosive composite technology puts the explosive composite device under water, and uses water instead of air as the propagation medium of detonation energy to realize the composite of two plates. In order to meet the specific needs of customers, the project team carried out technical research and made this 6㎡ composite heat-resistant steel plate. It is reported that the imported 601 heat-resistant steel has good heat resistance and oxidation resistance, mainly used for the production of sintering furnaces, Muffle furnaces and other electric heating equipment, the performance is far better than the domestic 310S heat-resistant steel, but the price is 8 times the latter. This time, the project team used underwater explosion technology, successfully combined the 2mm thick 601 heat-resistant steel with 4mm thick 310S heat-resistant steel, not only reducing the use of expensive 601 heat-resistant steel, the cost was reduced by 50%, and the resulting composite material was similar to 601 heat-resistant steel in performance. It is worth noting that the traditional air explosion composite and rolling technology is difficult to meet the processing needs of this special composite material. When the thickness of the cladding plate is less than 2mm, the explosive composite in the air often encounters problems such as the fracture of the cladding plate, surface ablation and the reduction of the binding rate. In contrast, the underwater explosion composite technology shows significant advantages in this type of sheet composite, which can achieve the thinnest composite thickness of 0.1mm, and the process is more stable and reliable, in addition to significantly reducing noise and pollutant emissions. |
为满足客户的特定需求，项目组开展技术攻关，制作了这块6㎡复合耐热钢板。据悉，进口的601耐热钢具有良好的耐热性和抗氧化性，主要用于制作烧结炉、马弗炉等电热设备内胆，性能远优于国产的310S耐热钢，但价格却是后者的8倍。此次，项目组采用水下爆炸技术，成功地将2mm厚的601耐热钢与4mm厚的310S耐热钢进行复合，不仅减少了昂贵的601耐热钢的使用量，成本降低了50%，而且所得到的复合材料在性能上与601耐热钢相近。
