Heat treatment process of drill rod
The selection of drill rod quenching process is based on the steel used for alloy structural steel brazing tools. With the development trend of impact rock drilling machinery, a variety of series of products and types have been produced. In the production and manufacture of drill rod, only when the alloy structural steel is properly selected can the quenching process which can fully mobilize the advantages of the alloy structural steel be selected to ensure the quality and service life of the drill rod. Alloy structural steels have different quenching processes.
The selection of quenching process of drill rod is based on the basic regulations of drill rod and failure analysis of drill rod. The basic rules of drill rod vary according to the type. Causes of ineffective quality of drill rod: unscientific design of drill rod, shortcomings of each production process and improper use in the whole process of brazing production, etc.
Whether the quenching process is appropriate or not, and whether there are quality problems (the most fundamental problem) in product raw materials during quenching and tempering treatment. The key reason for eliminating the inefficiency of drill rod is to select proper quenching process to ensure internal quality after eliminating various external factors.
The selection of quenching process for drill rod must follow the principles of rationality, rationalization and feasibility analysis. At present, heat treatment technology presents a rapid development trend. In addition to basic conditioning treatment, electromagnetic induction heating, organic chemical conditioning treatment and vacuum heat treatment, there are new surface heating and heat treatment technologies such as high energy beam (laser, electron beam, etc.), physical vapor igneous rock, chemical vapor deposition, ion implantation and spraying paint. The drill rod is a slender component. There are great limitations in solving the problem that different parts meet different requirements. Therefore, different quenching processes should be applied to different parts of the drill rod which can not meet the basic quenching requirements. The rationality, rationalization and feasibility analysis should be taken into account when selecting the matching quenching process in various parts of the heat treatment technology.
