Bară din OȚEL TRASAT LA RECE
Cold drawn steel can be found in many consumer products that we use on a daily basis, as it has the physical and appealing characteristics that make it useful for many products. We’ve answered some common questions asked when it comes to cold drawn steel, also known as cold finished steel.
Ce este oțelul trasat la rece?
Oțelul care este tras trece printr-o serie de matrițe pentru a obține o formă dorită este cunoscut sub numele de oțel tras. Matrițele aplică o cantitate specificată de presiuni cu ajutorul unei prese de mașină, iar materialul de pornire de oțel trebuie de obicei trecut prin matriță sau o serie de matrițe de mai multe ori. Rece se referă la fabricarea oțelului trafil la temperatura camerei, ceea ce necesită o presiune suplimentară pentru a modela oțelul, dar oferă oțelului calități suplimentare și aspect estetic vizual.
What’s the Cold Drawn Steel Process?
Initially, a steel manufacturer starts with a starting stock of steel product – either hot rolled straight bars or hot rolled steel coils - that is brought down to room temperature. Regardless if the end product is bar, tube or wire, the undrawn steel product is drawn through a die, which stretches the starting stock into the desired shape and size. This is done with the help of a grip that attaches to the steel stock and pulls the steel through the die. To the naked eye, the steel does not change much in shape through a single pass through the die, and usually takes multiple passes before it takes on the desired end shape.
Acestea sunt beneficiile sârmei de oțel trase la rece
· More accurate dimensional size tolerances.
· Increased Mechanical Properties, higher yield strengths, tensile strength and hardness.
· Improved Surface Finish, reduces surface machining and improves quality.
· Allows for higher machining feed rates.
· Superior Formability, responds better to spheroidization
· Maximizes machinability, thereby reducing yield loss.
