Heat treatment is an essential basic process in the manufacturing process of rock drilling tools. Only through reasonable heat treatment can various mechanical parts give full play to the internal organizational potential of the material and ensure that they reach the required mechanical property indexes and have a long service life. Therefore, heat treatment is the main means to improve the quality of rock drilling tools and maintain the competitiveness of products. However, heat treatment is also an essential process that consumes energy. How to achieve energy saving and emission reduction in heat treatment of rock drilling tools is of great importance to production enterprises.

1. Professional heat treatment cooperation

Advanced heat treatment equipment, specialization in production, continuous improvement in organization and management, and a significant increase in equipment utilization all constitute specialized assistance in heat treatment. Only a comprehensive professional heat treatment assistance can maximize its energy saving.

2. Scientific heat treatment organization and management

Scientific management of production is the prerequisite for giving full play to the potential of energy-saving technologies and ensuring continuous manufacturing at full load is a very important energy-saving measure. The key to scientific management is that enterprises should select and train highly qualified personnel with high professional knowledge and management level.

3. Improving the quality of heat treatment products for rock drilling tools

Improving the quality of mechanical parts of rock drilling tools is to prolong the service life of rock drilling tools, so heat treatment itself is an effective energy-saving measure. The key to ensuring the quality of heat treatment is to establish a sound heat treatment quality system. The heat treatment process is special in the mechanical manufacturing process. Only by focusing on process control can a good quality result be obtained.

4. Adopt energy-saving heat treatment equipment

Adopt controllable atmosphere and vacuum heat treatment with less oxidation-free heat treatment, energy-saving heat treatment, and clean heat treatment equipment with less pollution. At the same time, the accessories of the furnace should also choose suitable materials and structures, and reducing their weight is also an important energy-saving measure.

5. Develop an energy-saving heat treatment process

On the premise of ensuring the quality of heat treatment, process designers should reduce the heating temperature of heat treatment and shorten the process holding time as much as possible; reduce the thickness or adopt the lower limit infiltration method; replace quenching and tempering with normalizing and other energy-saving processes.

In short, the energy-saving and emission reduction of heat treatment of rock drilling tools is inseparable from professional assistance, scientific organization and management, improvement of product quality, and energy-saving equipment and processes. At the same time, enterprises raise their awareness of the importance of energy saving and emission reduction in heat treatment, and then take effective improvement measures to ensure the rational use of resources.
