Industry scene:

Most steel products undergo a rolling process during production.

Rolling is a plastic deformation process in which the cross-sectional area of metallic material is reduced by passing it between two smooth or suitably shaped cylinders.

The metal material to be rolled is forced by the cylinders themselves, which rotate in opposite directions, connected to motors that provide the power of the rolling mill through friction. Each pair of cylinders is mounted in a cage, allowing it to rotate, and the combination of several cages constitutes a rolling train.

Continuous rolling is used for large-scale sheet metal production: the metal strip is passed through a furnace where it is gradually extended in length over 2-3 minutes and then wound into coils. In order to maintain continuity of energy supply, welding is provided between the tail of one roll and the head of the next, and separation is done before winding.

During continuous rolling, the product has no reversal of motion, but is deformed sequentially on several supports, and each support passes only once through the individual supports that make up the rolling train

Question:

The final stage of rolling requires the drying of any moisture left over from the previous cooling stages of the sheet metal before being wound into coils.

In fact, the sheet metal is first cooled by spraying it with sprayed water. Some of the water will drip, some will evaporate, but some will still remain on the metal plate. Moisture must be removed before the sheet metal is wound into coils, as without adequate drying the material can oxidize and degrade, affecting the quality of the final product.

Often, it is very difficult to simulate the blowing process and to size and position the blowing nozzles prior to the assembly stage.

HAPOO solution:

Our technical department produced the first prototype simulation tool for gas blowing simulation of sheet metal during continuous rolling, operated by appropriate use of the virtual simulation tool package provided by HAPOO.

For this type of application, we have developed the first version of a targeted and efficient simulation tool, which enables us to respond quickly and quickly to simulation requests from our customers in the metals industry.

Air blowing simulations have never been realized before because of their complexity, lack of dedicated models, and the high cost of engineering man-hours that result. This problem is then addressed by empirically sizing the nozzle.

Advantage:

Our software allows us to simulate a uniform layer of water being blown off the metal plate, so we can size nozzles more precisely than ever before while ensuring coverage of the entire surface to be dried.

We can more precisely define the operating pressure, the size and number of nozzles, resulting in compressed air savings at the manufacturer with significant economic advantages.
