保證合理有序的過(guò)鋼節(jié)奏,加大矯直測(cè)量次數(shù),確保矯直中心在一條直線上。制定矯直輥裝配標(biāo)準(zhǔn),保證安裝正確,有據(jù)可查。建立BH值與矯直輥間距的關(guān)系,做到合理配輥,保證輥縫在1-3mm之間。
Ensure a reasonable and orderly flow of steel rhythm, increase the number of straightening measurement, to ensure that the straightening center in a straight line. The assembly standard of straightening roller is set up to ensure that the installation is correct and can be checked up. The relatihip between the BH value and the spacing of the straightening roller is established, and a reasonable roll matching is made to ensure the gap between 1 and 3mm.
明確軸向位置,加大矯直壓力。不要單獨(dú)打8輥軸向,調(diào)整側(cè)彎時(shí)應(yīng)以每相臨的3個(gè)輥為一個(gè)調(diào)整單元,保證矯直穩(wěn)定性。側(cè)壁斜度的處理措施是經(jīng)常注意檢查各輥軸向位置,竄動(dòng)情況。注意在不同間隙情況下,矯直力的選取。流態(tài)冷床法的基本原理是:利用一定速度的氣流吹動(dòng)沸騰床上的固體顆粒,使之處于懸浮運(yùn)動(dòng)狀態(tài),依靠煤氣在流態(tài)層中的燃燒,使流態(tài)層具有要求的溫度,線材從中通過(guò)時(shí)冷卻,完成奧氏體的分解轉(zhuǎn)變。對(duì)H2與H3的測(cè)量做到每批抽查,以做到及時(shí)調(diào)整。
The axial is clearly defined and the straightening pressure is increased. Do not play the 8 roll axis alone. When adjusting the side bend, 3 rolls per phase should be used as an adjustment unit to ensure the straightening stability. The treatment of side wall slope is to check the axial and movement of each roll. Pay attention to the selection of maximum straightening force under different clearance conditi. The measurement of H2 and H3 is done in each batch, so as to adjust it in time.
處理后的線材強(qiáng)度可以等于或大于鉛浴淬火者的強(qiáng)度,這是其他各種線材軋后控冷索氏體化處理方法所不及的。其他優(yōu)點(diǎn)是冷卻溫度比較均勻,溫差不大于5~10℃,而且不具有粘著性,不會(huì)像鉛浴或鹽浴處理時(shí)出現(xiàn)掛鉛、掛鹽現(xiàn)象。
The strength of the treated wire can be equal to or greater than that of the lead bath quenched. This not enough for all kinds of wire rod after cooling suxhnite treatment. Other advantages are that the cooling temperature is more uniform, the temperature difference is not more than 5~10 degrees C, and it does not have the adhesion, and it will not appear as lead or salt hanging during the lead bath or salt bath treatment.
