首先確定所需壓力的大小，主要取決于以下幾方面：被矯鋼材的品種、規(guī)格；待矯軋件的原始彎曲程度；待矯軋件的終軋溫度；被矯軋件的機(jī)械性能；矯直溫度等。

First, determine the size of the required pressure, which mainly depends on the following aspects: the varieties and specificati of the straightened steel, the original bending degree of the rolled piece, the finishing temperature of the rolled piece, the mechanical properties of the leveled piece, the straightening temperature and so on.

經(jīng)常檢查相應(yīng)輥面磨損情況，有積瘤的要及時(shí)清理；觀察進(jìn)鋼情況，保證入口導(dǎo)位位置正確；經(jīng)?？砍C直盤圓角與成品圓角；制定合理的矯直力，盡量避免回矯；合理控制冷卻過(guò)程；保證型鋼低于80℃進(jìn)入矯直機(jī)；注意觀察各輥軸向、垂直竄動(dòng)量，做到及時(shí)應(yīng)對(duì)。

Always check the corresponding roller surface wear, a tumor of the product to clean up; on steel, ensure the ce guide the correct ; often straightening and finished plate fillet fillet; reasonable straightening force, try to avoid the back; the reasonable  of the cooling process; ensure the steel is lower than 80 DEG C into the straight machine; observe the roll axial and vertical movement, timely respe.

工藝過(guò)程是：線材出精軋機(jī)后先入水冷導(dǎo)管進(jìn)行急冷，冷卻到650～750℃，經(jīng)成圈器成圈后落入流態(tài)床中。流態(tài)床用流動(dòng)的、導(dǎo)熱性好的粒料(鋯砂，含ZrO267.2%；在型材生產(chǎn)線上，冷床對(duì)型材還具有預(yù)彎曲功能，防止型材在自然冷卻過(guò)程中因各處質(zhì)量不等導(dǎo)致出現(xiàn)不規(guī)則彎曲。SiO232.8%)作媒介，用鼓風(fēng)機(jī)攪動(dòng)這些顆粒呈懸浮運(yùn)動(dòng)狀態(tài)，如同鉛浴池中的鉛液沸騰一樣。

The process is as follows: after the wire is finished, the first step is to enter the water cooling pipe and then to cool it to 650~750 degrees. The flow bed is used as a medium for flowing, good thermal conductivity particles (zirconium sand, containing ZrO267.2%; SiO232.8%). The particles are stirred by the blower to move in suspension, just as the lead liquid in the lead bath is boiling.
