2. be move bottom pilot hole (rolled piece own wt factor) because rolled piece enters the motion after nozzle, objectively cause cooling water can not carry out effective Homogeneous cooling to rolled piece, as shown in Figure 4, in Fig. 4: A: rolled piece, B: cooling zone.
Shown in Fig. 4, the volume of rolled piece top cooling medium reduces gradually to rolled piece bottom, when uniform compression is constant, volume, the flow of upper and lower cooling water are inconsistent within the unit interval, cause upper and lower heat exchange degree disunity, rolled piece can not be cooled (temperature deviation) uniformly, thus causes the inherent crystalline particle size of product material uneven, after phase transformation, the mechanical property disunity of product, have impact on the inherent quality of product.Because the upper and lower heat exchange degree varies of product causes (temperature deviation), the surface color of product certainly will be caused different and produce male and female face, have impact on the surface quality of product.
3. cause the pressure increase in pilot hole due to the heat steam of generation when carrying out heat exchange, thus increase the resistance of motion and the cooling water intake resistance of rolled piece, easily cause heap steel accident and cause heat-exchange capacity to reduce because of the less of cooling water flow.
4. the nozzle of traditional structure is overall structure (as shown in Figure 1), and when unrenewable and entirety is scrapped after pilot hole wearing and tearing, service life is short, and production cost is high.
