Hydraulic rock drills are currently the main mechanical equipment widely used in the construction of mines, railways, highways, hydropower, coal and construction projects. At present, there are dozens of foreign companies that are engaged in the development and production of hydraulic rock drill equipment. There are hundreds of types of hydraulic rock drills produced and they all have their own series. This type of hydraulic rock drill developed independently by the company is one of the research contents of medium and high-end engineering machinery equipment and key components in the strategic emerging industries of Hunan Province. Its successful R&D has a powerful impact on the domestic market of foreign hydraulic rock drills and the development of China's construction machinery industry. has great significance.

There are many problems in the recovery of copper chips directly into the furnace, the recycling of copper brass chips reduces the production cost of foundry enterprises and greatly improves the market competitiveness of the enterprises. The copper scraps are small, loose, directly into the furnace will be seriously blocked, the material block clearance is the furnace gas rising channel, directly affect the smelting process, the loose steel scrap without pressing, extremely easy to float on the furnace lining, corrosion lining, and large loss of raw materials will cause low molten iron rate.
