1045 Forged and Hot Rolled Steel Bars Process

1045 Forged and Hot Rolled Steel Bar is used where greater strength is required than can be obtained from the lower carbon steels. It responds to heat treatment, and a wide range of properties can be obtained. Applications include shafts, machinery parts, bolts, pinions, gears, etc.

1045 Forged and Hot Rolled Steel Bars Process:

Step1: Our process begins with either hot-rolled steel coils or hot-rolled straight bars from the mill. When hot-rolled bars are used, they are drawn individually. When coils are used, overhead cranes use C-hooks to safely lift the coil onto the “Payoff-Decoiler.”
Step2: Steel unwraps from the “Payoff De-Coiler” and is fed through the horizontal and vertical pre-straightener rollers to “break the memory” of the coil.
Step3: Steel continues on through the shot blaster so that the surface of the bar can be cleaned of all scale and rust.
Step4: Now the steel is push-pointed through a die. The drawing unit will then pull the steel through that same die, in a continuous motion.
Step5: Continuous straightening is maintained by passing the steel through more rollers.
Step6: Non-destructive testing is in place on all drive lines to ensure that surface defects from the raw materials are being detected and sorted out.
Step7: More straightening processes are in place throughout the draw line.
Step8: Shear barrels or shear knives will shear or cut the bar to the customer’s desired length.
Step9: The final straightening process occurs at the 2-roll straightener when the bar passes through the large concave and convex rolls. Guide blades, angles and pressure all contribute to the final straightness of the bar.
