[0002] In the mining area and oilfield processing industries, strip steel is often used as raw material. Strip steel is a steel plate with a relatively thin thickness, a relatively narrow width, and a very long length. Its width is generally between 20 mm and 200 mm and is supplied in coils. During the processing of strip steel, a leveling machine is required. The leveling machine extrudes a strip steel with a certain thickness through upper and lower rollers to achieve the effect of leveling the strip steel. Generally, the roll shafts of the leveling machine are mainly arranged in an upper four - lower five or upper three - lower four pattern.
