SCS technology took shape in Japan's Shinichi Corporation in 2001, and in 2003, SCS patented technology was formed in TMW Corporation in the United States. SCS treats the surface of steel through brushing, avoiding the disadvantages of environmental pollution caused by pickling. Its core equipment is the brushing machine, which is composed of a series of fully automatic and high-speed stainless steel wire brush rollers. Each brush is essentially It is a wire brush roller surrounded by a wire brush or a special abrasive with a rough surface. The brush roller rotates at high speed in the opposite direction to the movement of the rolled piece to remove the oxide scale on the upper and lower surfaces of the strip. The brushed iron oxide scale is washed away using a closed circulation cooling water flushing system. The thickness of SCS coiled wire is 1.09-6.35mm, and the brush update cycle is once every 20,000 tons of sheet or 40,000 tons of steel coils produced. The surface of the steel plate treated by SCS does not require any oiling treatment. The steel plate will not rust after being stored for 4 years under normal circumstances and is easy to store. This is because the pickling agent removes all the oxide scale, leaving a clean but rough surface. surface. The SCS brushing process does not completely remove the oxide scale. The loose iron oxide scale can be completely removed, and most of the thin, strong iron oxide scale next to the steel surface remains intact, which prevents oxidation and does not affect the subsequent primer and painting compared to pickling. On the other hand, SCS can also trim, stretch and straighten steel plates, and eliminate stretch-straightening lines on coiled plates.
