Annealing Furnaces
Our modern continuous type spheroidzing annealing furnaces are used for volume orders. Atmosphere gas heat treatment in these furnaces use NX gas + RX gas, and the gas is circulated by powerful fans to improve the temperature distribution and maintain equal hardness throughout the coils to produce a stable quality with free decarburization annealing wire rods.

Pickling Plant
Automated equipment in our pickling plant includes fully automatic pickling equipment with PLC control residence time in each tank. This system avoids wasted materials and delivers stable product quality by eliminating man-made errors. Besides, an imported Austrian ring-type track system and an automatic overhead crane reduce the occupational hazard and achieve safety requirements. In addition, the human-machine interface and on-screen controls can be operated by one person, which is an improvement over the conventional multi-person operational approach. Automatic transportation and handling systems provide employees with a user-friendly workplace while insuring the finest quality.
