The application discloses a steel bar production line intelligent scheduling system based on artificial intelligence. In the application, the dynamic adaptation problem of multi-specification steel bar mixed production is solved through a virtual-real fusion decision mechanism. In view of the demand of alternate rolling of screw thread steel and bright round steel, the system analyzes order parameters in real time, dynamically optimizes the matching logic of roll gap adjustment sequence and cold bed stepping rhythm, and ensures that the steel bars with different surface characteristics reduce transition waste during process switching. Through equipment health degree prediction and material mechanics simulation, the peak value of the main drive of the rolling mill is automatically reduced and the cooling time is prolonged when high-strength steel bars are rolled, so that the roll peeling or internal cracks of the steel bars caused by stress mutation are avoided. For small batch orders, the system intelligently compresses the shutdown window of die and groove changing, pre-adjusts the process parameters by using the idle gap of the equipment, and significantly reduces the production capacity breakpoint caused by specification switching.

Conventional 3D printing incorporates the use of axisymmetric nozzles and backpressure to horizontal beads with hemispherical ends. Only a subset of the material in conventional beads contributes to the load path as the hemispheres are considered wasted material.

The present disclosure describes the use of non-axi symmetric nozzles without backpressure to control extrudate flow, which enables extrusion of beads with arbitrary shape and direct control of extrudate flow. The microstructure produced through non-axisymmetric extrusion facilitates a significant heat conduction to peripheries of a printed layer, resulting in rapid cooling behavior, which allows higher manufacturing throughputs and prevention of warping and residual stresses in the extrudate.
