Process of Cold Heading Quality Wire(CHQ Wire):
Pickling & coating
The hot-rolled coil or wire rod passes through the pickling line, where hydrochloric acid solution is used to remove surface scale for clean surface finish before further processing and to form a lubrication film on the surface to reduce the coefficient of friction in the drawing and cold working process. The Gantry Crane moves between the tank during the process.
Packing of Cold Heading Quality Wire(CHQ Wire):
SMC Products are packed and labeled according to the regulations and customer's requests. Great care is taken to avoid any damage which might be caused during storage or transportation. In addition, clear labels are tagged on the outside of the packages for easy identification of the product I. D. and quality information.

Intermediate drawing
This process which produces half-finished products for the following stage improves the spherodized ratio during spheroidized annealing. The wire drawing machine composed of Supply Stand ,Drawing Drum, Take up stages produces half-finished coil products.
Spheroidized annealing
This annealing process with the purpose of obtaining spheroidized carbides facilitates the cold works. Once inserted in the heat treatment furnace, the process takes place in the order of controlled heating up to a given time, temperature and furnace atmosphere, along with maintenance at such temperature during a certain period and cooling controlled in accordance with the purpose intended. This process is controlled by automatic heat cycle.
Pickling & coating
The hot-rolled wire rod passes through the pickling line, where hydrochloric acid solution is used to remove surface scale for clean surface finish before further processing and to form a lubrication film on the surface to reduce the coefficient of friction in the drawing and cold working process.
Skin pass
The wire drawing machine produces half-finished coils where products meet the customers' needs in terms of the size and mechanical properties of products.
