Processing is different from blank making technology and cutting technology. Cold heading blanks, forging blanks, casting blanks and welding blanks can produce blanks with a certain shape and large size, which are very conspicuous. Cutting process can produce all kinds of precise and beautiful high-precision high-strength hot-dip galvanized bolts, which are extremely eye-catching. The heat treatment technology is the "internal science" of fastener manufacturing. What gives high-strength bolts is performance, which is neither visible nor dew. For this reason, although heat treatment is many times more valuable than other technologies in the economic and affordable chain of high-strength bolts, it is not taken seriously.

Although heat treatment endows the material with the ultimate performance and the high-strength bolt with the ultimate service performance, it is marginalized and attached. Under the trampling of formalism and quick success, heat treatment, the core technology of materials, high-strength bolts, and high-end mechanical equipment, has been excluded from the key technologies of the national science and technology development plan, and has not received key research support; and professional education has degenerated, The loss and scarcity of professionals, the backward and backward technologies, and the widening and widening of the gap with the foreign advanced level. It is no exaggeration to say that heat treatment is marginalized and attached, which is an important reason for the "three major problems" of my country's high-end mechanical equipment and high-strength bolts. It is also an important reason for my country's high-strength hot-dip galvanized bolts in the low-end manufacturing and competitive weakness. reason.

Heat treatment technology promotes the development of high-strength hot-dip galvanized bolts

Advanced manufacturing technology is the technical support for the development of advanced high-strength bolts. Heat treatment technology is an important part of advanced manufacturing technology and plays a very important role in the development of high-strength hot-dip galvanized bolts and high-end mechanical equipment. As we all know, it does not become a material without "components", and it does not become a material without "heat treatment". However, traditional customs often recognize the importance of "components", but do not recognize the important role and status of heat treatment.

Heat treatment is directly related to a material power. Without heat treatment innovation, there is no material power. my country's backward heat treatment technology has restricted the development of a material power, and the material heat treatment technology is original. As everyone knows, the lack of attention to heat treatment and the lack of innovation restrict the innovation and development of advanced materials. Without heat treatment innovation, there will be no advanced materials.

In the face of "Industry 4.0" and the "Third Industrial Revolution", in the development of high-strength hot-dip galvanized bolt manufacturing, the intelligent, green, and lightweight heat treatment technology will all play an important role. In the next 10 years, my country will tighten For the development of firmware, the process that plays a fundamental and breakthrough role in the development of the fastener industry should be selected as the focus to accelerate development. Paying attention to integrated innovation is the key to improving the core capabilities of high-strength hot-dip galvanized bolts. The development of heat treatment will be more present. personalise.
