Hongchuang is present in a series of industries for preheating—primarily the automotive, cable and wire, electrotechnical, and tube and pipe industries. In many cases, our preheating solutions are integrated into production lines.
Using induction rather than gas or a furnace for preheating has several advantages. Heat transfer is direct—minimizing heat loss and energy consumption while increasing the production rate and improving quality.
The heat can also be controlled precisely. This makes it possible to reduce the temperature when welding and then achieve a lower cooling rate. Less risk of cold cracking and excessive hardening are some of the benefits.
And you can forget heat-spreading flames. You get a better working environment, less need for cooling and a lower fire risk.
