Precision Steel Tube
Precision tube is a kind of seamless steel tube with high precision and high brightness produced by cold drawing or cold rolling process. Its inner and outer diameter size can be accurate to less than 0.2mm, in order to ensure bending and torsional strength at the same time, the weight is relatively light, so it is widely used in manufacturing precision machinery parts and engineering structures. It is also used to produce all kinds of conventional weapons, gun barrels, shells, bearings and so on.
Precision seamless steel tubes with the traditional electric furnace + forging or forging billets and rolling. Product appearance bar, square, forgings. Turbine plant and then for further processing, but the process is more special, after processing the metal utilization rate of about 30%. After extrusion production mode, will have the following advantages:
1, precision hot-rolled seamless steel pipe in the best stress state, reducing the internal defects.
2, easy to achieve cross-section morphology diversity, adapt to varieties, small batch production.
3, in every direction of the performance uniformity.
The main method of production extrusion process: electric furnace + electric furnace> forging or rolling - induction heating> extrusion - annealing.
Squeeze forging, rolling method is the difference:
1, precision seamless extrusion heating temperature than forging, rolling high 30-60 ℃;
2, deformation, high-speed (rebar, only 2-4s).
3, multi-step, high consumption of metal.
