Torque tube Introduction of:

There are two main consumption modes of rectangular tubes, namely, cold rolling and hot rolling. Rectangular tube hot rolling is made of hot rolled strip steel after processing. Cold drawn or cold rolled fine rectangular tubes. Cold rolled rectangular tubes are cold drawn or cold rolled fine rectangular tubes with high dimensional accuracy and good external brightness for mechanical structures and hydraulic equipment. The cold drawn rectangular tube, as the starting material, is a hot rolled coil. When it is used, an acid is used to absorb the above oxide skin, and then the cold rolling is stopped to improve the cold rolling, steel tube, hardness and strength of the consumed cold rolling, but the toughness will drop slightly. Therefore, this will lead to performance degradation when stamping, and the consumption of cold-rolled rectangular tubes can only be a simple deformation parts manufacturer. Cold rolling, continuous annealing process.
