The heat treatment process of the pick and the process characteristics of the pick

Brazing and heat treatment process research The brazing and heat treatment process of the pick is one of the key technologies to ensure the quality and life of the strong pick. At present, the production process of domestic picks is generally the following two:

What are the advantages of pick

The pick is the direct cutting tool of the shearer and the roadheader. The working conditions are very bad. During the use process, it is subjected to friction and impact from the coal seam or rock.

What are the precautions when using a drill

There are many precautions when using the drill. Below we summarize some related matters for you, you can take a look.

What are the characteristics of rotary digging teeth

In the existing mining equipment in our country, whether it is a shearer or a roadheader, the rotary digging teeth used are composed of a pick head and a pick body. The front end of the pick head is roughly a single cone structure.

Do you know the characteristics of rotary picks?

Strictly optimized geometry allows the picks to be subjected to uniform stress during machining, cutting smoothly, making the wear level as uniform as possible, and further improving the working efficiency of the picks, wearing the helical teeth and reducing damage , to improve the reliability of the rotary cutting pick.

What are the drilling methods of rotary drilling rigs?

A good operator should always know the type and intensity of geology to be drilled at this time, which rotary drilling rig drill pipes and tools, and which drilling methods are effective. Only then can the operation be controlled. Loads are reduced to low, wear is low, and footage is fast.

Do you know the technological process of rotary drilling rig?

Rotary drilling rig is a kind of construction machinery suitable for hole-forming operations in building foundation projects. It is widely used in municipal construction, highway bridges, high-rise buildings and other foundation construction projects.

What are the requirements for the design of rotary digging teeth?

The design improvement of the rotary digging teeth requires higher coal mining requirements, so the design of the rotary digging teeth is insufficient. If there are defects, the rotary digging teeth cannot play a major role, so the company cannot meet the mining requirements.

A brief introduction to picks

Pick consumption decreases with increasing shearer traction speed and increases linearly with drum speed. The reason is that with the increase of traction speed, the chip thickness of the pick increases, and the path for cutting coal and rock per unit volume becomes shorter, resulting in less pick wear and lower tooth loss.

What is the reason for the cold cracking of the shearer pick?

Picks include shearer picks, roadheader picks and rotary cutter picks. Different types of incisors have different effects. In mining and underground mining, shearer picks play an important role. TBM picks are mainly used in roadway excavation and tunnel excavation.
