作為拉絲原料的線材，雖然鋼種較多，但品種只有圓形的。為減少拉拔次數(shù)，直徑一般為5～9毫米，特殊用途的也使用直徑大于10毫米的線材。作為拉絲原料的線材，金華鋼廠家批發(fā)價，金華鋼廠家批發(fā)價，要求保證化學(xué)成分和物理性能均勻與穩(wěn)定，金相組織盡可能索氏體化，金華鋼廠家批發(fā)價，尺寸應(yīng)精確，表面應(yīng)光潔，氧化鐵皮薄而利于***。 </p> <p> 總的來說，線材的用途很廣，在國民經(jīng)濟各個部門中線材占有重要的地位。有的線材軋制以后可直接使用，主要作鋼筋混凝土的配筋和焊接結(jié)構(gòu)件用；有的則作為再加工原料，經(jīng)過再加工后使用。例如，經(jīng)過拉拔成為各種鋼絲，再經(jīng)捻制成為鋼絲繩，或再經(jīng)編織成鋼絲網(wǎng)；經(jīng)過熱鍛或冷鍛成鉚釘；經(jīng)過冷鍛及滾壓成螺栓，以及經(jīng)過各種切削加工及熱處理制成機器零件或工具；經(jīng)過纏繞成型及熱處理制成彈簧；等等。

對于異型材，在中軋和精軋階段盡量多使用萬臺孔型和多輥孔型。由于多輥孔型和***孔型有利于軋制薄而高的邊，并且容易單獨調(diào)整軋件斷面上各部分的壓下量，可以有效地減少軋輥的不均勻磨損，提高尺寸精度。 </p> <p> 型鋼連軋，由于軋件的斷面截面系數(shù)大，不能使用活套。機架問的張力控制一般是采用驅(qū)動主電機的電流記憶法或者是力矩記憶法進行。 </p> <p> 對于大多數(shù)型鋼，在使用上一般都要求低溫韌性好和具有良好的可焊接性，為保證這些性能，在材質(zhì)上就要求碳當(dāng)量低。對這些鋼材，實行低溫加熱和低溫軋制可以細化晶粒，提高材料的機械性能。在精軋后進行水冷，對于提高材料性能和減少在冷床上的冷卻時間也有明顯好處。 </p><div style="width:100%;text-align: center;"><img

</p> <p> 普通工字鋼，輕型工字鋼，由于截面尺寸均相對較高、較窄，故對截面兩個主軸的慣性矩相差較大，這就使其在應(yīng)用范圍上有著很大的局限。工字鋼的使用應(yīng)依據(jù)設(shè)計圖紙的要求進行選用。 </p> <p>
