Line Features

Applied the United States Steel Hot-dip Galvanizing process to indirectly heat with the full-radiation pipes;
About strip cooling, using protection gas cycling jetting cooling device and frequency adjusting to cool the strip quick and evenly and to ensure the suitable temperature of into zinc pot;
Applied the thickness gauge to monitor and feedback the actual weight of cladding and adjust the air knife ;(to achieve the close circuit control);
Motor of air knife is applied to frequency speed regulation control and its adjusting is used the high precision drive control to adjust the air knife rightly and to ensure the even cladding thickness and good surface quality;
