KALDDRAGNAÐ STÁLSTARI
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.
Hvað er kalt dregið stál?
Stál sem er dregið fer í gegnum röð deyja til að ná æskilegri lögun er þekkt sem dregið stál. Deyjur beita tilteknu magni af þrýstingi með hjálp vélpressu og venjulega þarf að fara í gegnum steypuna eða röð stansa oftar en einu sinni. Kalt vísar til þess að teiknað stál sé framleitt við stofuhita, sem krefst aukins þrýstings til að móta stálið, en gefur stálinu auka eiginleika og sjónrænt fagurfræðilegt útlit.
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.
Þetta eru kostir Cold Drawn Steel Wire
· 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.
