میله فولادی سرد
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.
فولاد سرد کشیده چیست؟
فولادی که کشیده می شود برای رسیدن به شکل دلخواه از یک سری قالب ها عبور می کند که به فولاد کشیده شده معروف است. قالب ها فشارهای مشخصی را با کمک پرس ماشینی اعمال می کنند و استوک اولیه فولاد معمولاً باید بیش از یک بار از قالب یا مجموعه ای از قالب ها عبور داده شود. سرد به فولاد کشیده شده اشاره دارد که در دمای اتاق تولید می شود، که به فشار اضافی برای شکل دادن به فولاد نیاز دارد، اما به فولاد کیفیت اضافی و ظاهر زیبایی بصری می بخشد.
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.
اینها مزایای سیم فولادی سرد کشیده شده است
· 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.
