Causes of 20CrNi3 Shank Adapter Fracture
The reasons for the fracture of 20CrNi3 shank adapter are excessively high quenching temperature, unstable residual stress and phase transformation, etc.
The reasons for the fracture of 20CrNi3 shank adapter are excessively high quenching temperature, unstable residual stress and phase transformation, etc.
The reasons for the collapse of the 23CrNi3Mo steel shank afapter involve many aspects such as materials, process, design and use.
Casing drilling brings higher efficiency, lower cost and better safety to drilling projects through its unique process and design.
The excellent anchoring performance and reliable working condition of expandable rock bolts provide a new solution for surrounding rock control in deep mining.
The operation mode of connecting and unloading rods directly affects the overall work efficiency and the service life of rock drilling tools.
The failure causes of DTH drill bits include end face cracking and alloy tooth breakage, which directly affect the progress of the operation.
DTH hammer improves mechanical drilling speed, reduces drilling costs, and shortens operation cycle. It is an important tool in modern drilling.
Taking various factors into consideration, we can scientifically select the rock drill bit diameter to achieve the best rock drilling effect.
Self-drilling anchor bolts enhance the support effect and reduce construction costs in solving geological disasters such as mountain collapse and landslide.
Split set’s excellent technical performance, simple construction method, and significant economic benefits make it the preferred solution for tunnel supports.
The continuous changes in technology and market demand will continue to promote the technological development of hydraulic rock drills.
Many factors affect the intelligent carburizing of rock drilling tools,by taking appropriate measures, we can improve its performance and service life.
Exploration of the root causes of DTH drill bit tooth loss and effective preventive measures are of great significance to improving drilling efficiency.
DTH hammer drilling with casing solves problems under complex geological conditions and injects motivation into geological exploration with its high efficiency.
Threaded button bits have several hardened buttons on their surfaces that effectively crush and fracture rock.
