The development of rock drilling tools promotes the progress of rock drilling technology, which cannot be without input from the manufacturers. Qualified raw materials, advanced production technology, and production equipment are essential if manufacturers want to produce high-quality rock drilling tools. So we can analyze the industry market of rock drilling tools from these aspects.
The raw materials of rock drilling tools are mainly steel and cemented carbide. The manufacturers that produce the raw materials of rock drilling tools in the market include Timken and Shanghai Baosteel. There are many famous cemented carbide manufacturers, for example, Zhuzhou Cemented Carbide Group Corp. Ltd. Sandvik and Atlas Copco are well-known rock drilling tool manufacturers in the industry.
There are many kinds of rock drilling tools, such as drill bits, drill rods, shank adapters, etc., but with different materials.
1. Hollow steel brazing steel for rock drilling rods
The drill rod material is mainly 55SiMnMo, which is the leading steel of the H22.
2. Drilling tools for light rock drilling machinery
Light-duty rock drills mainly use H22 hexagonal drill rods, and anchor drills use H19 drill rods.
The material of bit skirt body is mainly 40Cr or 42CrMo, and the alloy of the drill bit is YG8-11.
The production capacity of drill rods and drill bits are large, and the supply exceeds the demand. The competition is fierce, and every factory is fighting a price war.
3. Drilling tools for rock drilling rigs
A. Hydraulic mining rig
Large underground metal mines mostly use Atlas Copco and Sandvik rock drilling tools. The material of the drill rod is mostly 23CrNi3Mo.
B. Hydraulic excavation drilling rig
The commonly used lengths of the drill rod for the excavation trolley are 3.09m, 3.7m, 5.25m, and D45and D48drill bits with seven buttons.
C. Open-pit hydraulic rock drilling rig
In hydropower, mining, and quarrying projects, Common drill rods are T38 and T45, with lengths of 3.66m.
4. Drilling tools for DTH drilling rigs
DTH products include high air pressure, medium air pressure, and low air pressure. With rapid development, especially low-pressure products are facing fierce price competition.
Cutting picks include coal mining picks, engineering picks, and mining picks. Its shape has flat teeth and bevel teeth.
A. Coal mines: large coal mines mainly use multi-purpose shearer machines. In the past, more flat teeth were used, while more bevel teeth are currently used.
B. Engineering use: road milling machine (mostly cold milling), each disc has more than 100 bevel teeth.
C. Mining pick: it is used for surface rock and soil stripping of shallow metal ore, cone teeth are very thick and long.
6. Drilling tools for roller cone drills
A. Oil drilling rig: The quality requirements are strict.
B. Mining roller cone drilling rig: the commonly used specifications are D250mm and D310mm.
7. Drilling tools for shield machine
The maximum diameter of the shield machine disc can reach 16 meters.
There are two types of shield knives: hob and cutter. The material of the hob is hot work die steel. Cutter and edge knives come in many sizes and shapes, with steel bodies and carbide heads.
8. Drilling tools for metallurgical furnaces
It includes a blast furnace outlet, ladle slag tapping, drill rod, drill bit, shank adapter, and coupling sleeve for ferroalloy furnace slag discharge. With hydraulic rock drill as the power source. It’s not very technical.
Nowadays, the use of rock drilling tools is becoming more and more widespread, and people’s requirements on the types, performance, and quality of rock drilling tools will be higher and higher. As a rock drilling tool manufacturer that wants to develop continuously, we should grasp the market development trend of the rock drilling tool industry and produce more and better rock drilling tool products to meet the market demand and continuously improve the product level of the whole industry.
