Zhengzhou Gou's induction heating equipment manufacturer tells you about the development status of domestic steel bar and steel wire heat treatment production lines

Some time ago, a Sri Lankan customer purchased a steel bar heat treatment production line based on medium frequency induction heating power supply from our factory. According to my colleague, the customer was very satisfied with this production line. It can be seen from this that at present, my country's research and development and production of steel bar and steel wire heat treatment production lines are quite mature. Today, the editor will tell you about the specific development status of domestic steel bar and steel wire heat treatment production lines.

Domestic steel wire and steel bar heat treatment production lines have experienced more than 20 years of development, production and improvement. Starting from the concave thread prestressed pipe pile steel wire production line, it has developed into stainless steel wire, low relaxation steel wire, steel strand, spring steel wire and other varieties. . The production line has evolved from a single line to a double line; the power supply configuration has evolved from a combination of thyristor intermediate frequency and tube super audio to a combination of thyristor intermediate frequency and IGBT transistor power supply to achieve the purpose of reducing energy consumption and increasing productivity.

The pipe pile steel wire heat treatment production line has developed from single-line production to double-line production to solve the problem of uniform load temperature of the two steel wires. In addition to improving productivity, the use of double-line production covers an area almost the same as that of a single-line production, and there is no need to expand the factory building. Compared with single-line production, the equipment investment cost is slightly increased rather than doubled. According to calculations by the production unit, 50kW·h can be saved per ton of steel. electrical energy. Therefore, dual-line production has a broader future. Compared with similar products in the world, double-line production is advanced.
