How to Improve the Service Life of Hydraulic Breaker Drill Rod

How to improve the service life of the Hydraulic Breaker drill rod has always been a matter of great concern. The longer the service life of the drill rod, the higher the work efficiency, and correspondingly the lower the maintenance cost. So, in the daily use of the Hydraulic Breaker drill rod, how can we effectively improve its service life? The following will provide the answer:

Cemented carbide rock drilling tools (bit, drill rod, whole drill rod, etc.) are a new weapon for human beings to conquer rock and ore. They form a slender rod system. Under the severe wear of rock and ore and the erosion and corrosion of high-pressure water flow (or air pressure) and pit water, they bear the high-frequency impacts of tension, compression, bending, torsion and rock drill about 2000-9000 times per minute, with each impact energy up to 25-500j, and often fail in the way of stress Corrosion fatigue fracture, The service life is only a few tens of minutes to several tens of hours.

Therefore, rock drilling tools are a large number of consumable tools that are essential for basic industries due to their harsh stress conditions, short service life, high technological content, and high technological content among all human mechanical tools. Mining workers from over 100 countries and regions around the world work 8 hours a day, with over half of their time drilling holes in rock and ore. The annual consumption of rock drilling tools required is about 50 times that of the domestic market in China.

How to Improve the Service Life of Hydraulic Breaker Drill Rod

China produces approximately 7000t of hard alloy for cutting tools and rock drilling tools annually, ranking first in the world in terms of production and quality, which is close to the international advanced level. The annual consumption of drilling steel and tools by the national mining engineering department is 30000 tons and over 30 million pieces, with a value of approximately 2 billion yuan. The international rock drilling tool market has an annual capacity of up to 10 billion US dollars. The popular price of rock drilling tools in the domestic market in China is only one-third to one-tenth of the international market price of similar and equivalent drilling tools. International famous drilling tool companies such as Sweden's 5andvik and secoroc, relying on their technological and economic advantages, mostly import cheap tungsten ore from China, while exporting hard alloy drilling tool products at high prices. According to statistics from Swedish company 5andvik in the 1990s, its annual sales of drilling tools reached 2.4 billion US dollars.

Due to various historical reasons and years of outdated drilling tool technology and production management, China has not yet emerged with talented and strategic drilling tool industrialists and famous multinational drilling tool companies under the current system. So far, the annual foreign exchange earnings of rock drilling tools in China are only over 10 million US dollars. The foreign exchange earned by long tools such as drill rods and whole drills accounts for less than 1/4 of the total foreign exchange earned by the tools. The poor quality, short service life, and instability of domestically produced drill steel have become the main "bottleneck" restricting the modernization of China's drill steel tools and mining industry, as well as the export of long drill tools.

The above are effective measures to improve the service life of crushing hammer drill rods, hoping to be helpful to you. Improving the service life of drill rods requires our drill tool manufacturers to continuously strengthen their production processes and adopt better materials. Only in this way can we drive the development of our drill tool industry and make improving the service life of drill rods no longer a challenge.
