Spring Steel Wire Production In The Energy Saving And Environmental Protection

    1 surface treatment of energy-saving transformation

    Spring steel wire in the production of surface treatment, mainly to remove the wire or semi-finished steel wire oxide scale, and increase the coating, in order to facilitate the process after the drawing of the lubricant into the common surface treatment for large pond pickling, phosphating, etc. Process, the process due to the whole winding processing, large pool of open, pickling and phosphating and other processes need to heat, resulting in surface treatment is neither energy nor environmental protection, and product quality control is also more inconvenient, the transformation of a huge space, At present, there are several kinds of surface treatment process can learn from the application:

   (1) mechanical stripping + online continuous chemical pickling or ultrasonic cleaning + boron on-line processing, the technology is mature, in the steel cord, cutting wire, bead wire and high pressure hose and other products mature application, with high production efficiency , Product quality and stability, with less acid, relatively energy saving;

   (2) shot peening + electrolytic phosphating, also occasionally applied to the surface treatment requirements of the spring wire, is also a better production process, high-speed iron pills on the wire surface quality improvement, improve spring life great benefit;

   (3) mechanical shelling + belt processing + online Tu Peng, but the belt cost is relatively high, but more environmentally friendly;

   (4) tunnel-type closed pickling system, the system is the whole volume of the surface treatment, but the high level of automation, wire rod in the closed tunnel kiln in the pond cleaning, acid utilization is high, but the investment is large, An annual output of 100,000 tons production lines, investment up to 600 million.
