2) Function and Structure

straightening machine will continually draw out the blank and make it straight when teeming；The drawing roller reverses and carries the dummy head into the mould when rolling.

Use single rack with 5 rollers combined straightening machine to make the blank continuously and uniformly distort, distortion velocity is low and steady, to overcome the peak of distortional ratio. It will decrease the flaw and fault above and inside blank, and fits for high speed and big section blank production.

Straightening machine is made up of driving roller, subsidiary roller, driving system, frame structure, water cooling system, and protective plate.
