冷床是中小型棒材車間不可缺少的輔助設備之一。它的功能是將軋機軋制后經(jīng)飛剪剪切成倍尺長度的棒材, 輸送并卸到冷床齒條上冷卻, 使其溫度由900℃降至100 ～ 300℃。

The cooling bed is one of the auxiliary equipment in the small bar workshop indispensable. It is the function of the bar rolling mill after double length flying shear, conveying and discharging to the cooling bed rack, the temperature 900 DEG C to 100~300 C.

處理后的線材強度可以等于或大于鉛浴淬火者的強度，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，不會像鉛浴或鹽浴處理時出現(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.

矯直板位于冷床入口側, 由制動裙板拔入的軋制棒材首先落到矯直板上, 使棒材保持大平直度。矯直板每塊長1. 15m, 寬250mm , 上有10個齒形, 塊與塊之間只留出動齒條移動間隙, 安裝在定支架上。

The straightening plate is located on the inlet side of the cooling bed, and the rolled bar pulled by the brake apron first falls on the straightening plate to maintain the maximum flatness of the bar. The straightening plate is 1. 15m long and 10 250mm wide. There is only a movable clearance between the block and block, which is installed on the fixed support.
