Stainless steel packaging steel strip continuous casting technology introduction

Stainless steel packing strip profile, stainless steel and high alloy stainless steel continuous casting technology of low content of impurities, few oxides in the process of coagulation precipitation and adhesion to the graphite die, the strip and the friction between graphite mould of the strip led pull resistance is small, simple & other; La - Stop & throughout; The program has enough. Only when the strip surface exudates increased even influence the surface quality, only it is necessary to attract 淸 program. Pure metal in liquid - in the process of solidification Solid two phase range is narrow, appropriate USES small trip to avoid big columnar crystal formation. To maintain the average lead pull speed constant can adopt low instantaneous speed of high frequency application. Small stroke, transient speed low and high frequency is to ensure the quality of stainless steel and high alloy stainless steel band billet basic conditions. Oxygen stainless steel in the process of solidification, graphite mold material itself the oxidation of carbon and stainless steel and stainless steel reaction use carbon, graphite mold surface pits may occur, then the strip led resistance increases, serious when crack of the strip surface. In this case if increasing casting temperature and speed, can make the relative to the graphite die strip solidification front of a constant area position back ward, which over the section has been rough on the surface of graphite mould, thus improve the strip surface quality.
