MA60A series 7-roller pipe rod straightener machine is a vertical pipe rod straightening machine with horizontal cross arrangement of straightening rollers. The straightening roller is an elliptical translation curve, which is more advanced than the traditional hyperbolic roller. It is mainly used to straighten the bending degree of steel pipes and non-ferrous metal pipes and bars, to reduce the ellipticity of its section and to improve the surface roughness. It is applicable for pipe rod finishing equipment in cold drawn steel pipe plant and other machine factories.
