Problems solved by technology

At present, domestically produced stainless steel clad steel plates are welded with traditional civilian explosives, such as ammonium antimony (ammonium oil) explosives, which are the most produced and widely used in my country. However, due to the strong hygroscopicity and agglomeration of ammonium nitrate, this Explosive-like explosives have high detonation velocity, easy agglomeration, and difficult control of density, which greatly reduces the explosive performance of explosives. The instability of explosion transmission causes the initial explosion bonding rate to be below 99%, and the utilization rate of stainless steel clad steel plates is low, which is not suitable for the performance requirements of explosive welding.

Description

technical field [0001] The invention relates to a composite explosive of stainless steel clad steel plate and a preparation method thereof. Background technique [0002] Stainless steel clad steel plates produced by explosive welding abroad entered the industrial field in the 1960s. In the late 1980s, my country's explosive stainless steel clad steel plate was only used in a small amount in the industrial field. Due to the excellent performance-price ratio of stainless steel clad steel plate, it has been widely used in various industries in my country in just a few years. However, with the large-scale industrial production and the application of large-area clad The main factors that plague the development of enterprises. At present, domestically produced stainless steel clad steel plates are welded with traditional civilian explosives, such as ammonium antimony (ammonium oil) explosives, which are the most produced and widely used in my country. However, due to the strong h...
