HYKD500-B hydraulic rock drill is a kind of high-efficiency heavy hydraulic rock drill designed and manufactured according to the needs of ironmaking blast furnace opening project. As one of the professional hydraulic drifter manufacturers, we ensure it has the advantages of easy operation, high torque, strong drilling capacity, high chiseling speed, reliable use and convenient maintenance when used together with the opening machine in front of the furnace.

Our hydraulic rock drill for blast furnace opening machine adopts valve sleeve structure, the movement of piston in the bushing is similar to free hammer, without direct friction with the body, which significantly reduces the wear and tear, and realizes the super-long service life of “never wear and tear”. In addition, the cushion oil pad provided by the bushing also has the function of preventing runaway, avoiding mechanical damage caused by idling.

The company's self-developed hydraulic punching mechanism, as a key part of our hydraulic rock drill, adopts patented design, closed oil chamber, U-shaped sealing and other technologies to reduce friction loss and extend the life of the whole machine. In practice, the life span of rock drilling tools is greatly improved by smooth energy transmission, which reduces the cost of frequent replacement.

The hydraulic drive system reduces energy consumption by about 2/3 compared with traditional pneumatic equipment, and the operating noise is significantly reduced, which improves the working environment in metallurgical workshops. For example, the HYKD400 model, a popular hydraulic drifter for sale, has an industry-leading energy utilization rate while breaking rock with high efficiency, which is in line with the trend of green production.

China Hebei Hongyuan, as one of the trusted hydraulic drifter manufacturers, ensures our hydraulic rock drill has become the preferred equipment in metallurgical industry by virtue of its high efficiency in rock breaking, long service life, intelligentization and adaptability to all scenarios. Our hydraulic drifter for sale, including the advanced hydraulic rock drill series, are dedicated to meeting the demanding needs of metallurgical projects. China rock drill manufacturer.

The frequency of hydraulic rock drill is a very important technical requirement, which directly determines the drilling efficiency and the quality of the inner wall of the hole. The high frequency rock drill is characterized by the fact that at the impact point of the rock, when the first impact stress has not completely diverged, the second impact has already occurred. Therefore, a stress accumulation effect is formed on the rock impact point, and then the rock is broken rapidly. The higher the drilling frequency, the more concentrated the stress. In this case, the drilling efficiency will be doubled. The hole will be straighter and the inner wall will be smoother.

Due to the limitation of design structure and materials, the high-frequency rock drill generally does not exceed 30Hz, and the impact frequency of the foreign rock drill is about 29.5Hz. Although it can meet the demand of the blast furnace opening, the interval time is longer. The stress concentration on the blast furnace nozzle cannot form an effective result. Therefore, the opening efficiency is low and the loss of the drill bit is extremely large. Sometimes even two or three drill pipes are required to open a single hole. When the HYKD500 hydraulic rock drill is designed, the impact frequency is made to reach 50HZ. After many new materials and new processes, the actual-measured impact frequency is about 49.5-55HZ. This increase in the impact frequency is critical, the efficiency of the opening is doubled, and the consumption of the drill pipe and the drill bit is greatly reduced.
