With the rapid development of science and technology and the continuous improvement of automation, China's instrumentation industry will also undergo new changes and gain new development. The high technology of instrumentation products will surely become the mainstream of instrumentation technology and industry development in the future.
In the past 20 years, Microelectronic Technology, Computer Technology, Precision Machinery Technology, High Sealing Technology, Special Processing Technology, Integrated Technology, Thin Film Technology, Network Technology, Nanotechnology, Laser Technology, Superconductivity Technology and Biotechnology High-tech has achieved rapid development. This background and situation have continuously raised new and more demanding requirements for higher and more ambitious test transformers for instrumentation, such as faster speed, higher sensitivity, better stability, fewer sample volumes, and minimal inspections. Loss and lossless, remote sensing telemetry more distant, more convenient to use, lower cost, no pollution, etc., but also provides a strong impetus for the development of instrumentation technology and industry, and has become the material and knowledge for the further development of instruments and meters. And technology foundation.
In particular, we need to point out that in the past 10 years, we have included nano-scale research in precision machinery, achievements in modern chemistry at the molecular level, biological research at the genetic level, research achievements in high-precision and ultra-performance special functional materials, and global network technologies. The advent of a large number of contemporary technological achievements, including the promotion of application results, has brought about fundamental changes in the field of instrumentation. Through analysis, we can see that high-tech is not only the main feature of modern instrumentation, but also the only way to revitalize the instrument industry, and it is also the mainstream of instrumentation and its industry development in the new century.
With the advent of fieldbus, the process of process measurement and control instrumentation has undergone a major turning point and rare opportunities.
The current field bus has become a hot spot in global automation technology. Fieldbus is an open, fully digital, bi-directional, multi-station communication system used between on-site intelligent meters and control rooms. Its production is not only the actual demand of the vast number of users and the result of technological competition among manufacturers, but also the product and product upgrade of computer technology, communication technology and control technology in the field of industrial control, as well as the realization of further high precision and high performance. (In particular, multi-parameter on-line real-time measurement and control and automatic measurement and control), high stability, high reliability, high adaptability, multi-function, low consumption, etc. provide tremendous power and development space.
The application field, especially the further expansion of non-traditional application fields, has injected new vitality and new impetus into the continuous development of the instrumentation industry.
The overall development trend of instrumentation resistance tester instrument products is "six high, one long," and "twentieth." Throughout history, analyzing the status quo and looking to the future, we can come up with the following conclusion: In the future, traditional instruments and meters will continue to move toward high performance, high precision, high sensitivity, high stability, high reliability, high environmental protection and long life. "Long" direction of development. New types of instrumentation and components will be miniaturized (minified), integrated, integrated, electronic, digital, multi-functional, intelligent, networked, computerized, integrated automation, and optical-mechanical-electronic integration; The specialization, simplicity, family, personalization, and non-maintenance of services, as well as the development of automated, dust-free (or ultra-clean), professional, and large-scale "20-degree" development in services. In this “twentieth centuryâ€, the dominant, core, or key role is miniaturization, intelligence, and networking.
Heat Treated Steel Bar And Tube
Heat treated steel bar is produced by heating and cooling in different temperature based on the steel grades to improve the steel bar mechanical properties or machinability for various industrial applications. Heat treated steel bar includes annealed steel bars, Normalized Steel Bar, quenched and temper qt steel bar.
Annealed Steel Bar has better ductility and lower hardness, which can be easier to be machined. The annealing processing is usually widely used for steel grade with higher carbon content above 0.5%. However, some low carbon steel also requires to do annealing for special usage such as 20CrMnTi gear steel. For some special material such as 20CrMnTi gear steel and GCr15 such bearing steel, spheroidizing annealing is often required.
Normalized steel bar sometime is also one kind of annealing processing. It mainly changes the grain to remove the impurities in steel and improves the strength and hardness. For some hot rolled steel bars, to keep the basic mechanical properties, normalizing is often used.
Quenching and Tempering, abbreviated as Q&T is a king of processing that strengthen or harden steel bars by heating the materials and then cooling in water, oil or other liquid medium, that rapidly the change from austenite to perlite to get the proper properties for various usage. The quenched & tempered steel bar materials are usually with carbon from 0.30% - 0.60%, it is widely used as merchant bars in components of various machines.
Our advantages on producing heat treated steel bars:
1) Big stocks of hot rolled round bars or wire rods as raw materials
2) Wide range of Cold Drawn Steel Bar sizes: from 10mm to 150mm
3) Different cold drawing medias powder or oil to get different surface
4) Straightening machines to get better straightness up to 0.5mm/m
5) Grinding and polishing machines to get better roughness upto 0.4um
6) Heat treating furnaces to adjust the mechanical properties
7) Full sets of testing equipment to test the sizes, mechanical properties and microstructure.
8) Multiple packages to avoid broken packages and anti-rusty
