圣霖國際冷拉服務介紹

冷床下料裝置將其收集成組送至輸出輥道上, 再由輸出輥道將其送到冷剪剪切成定尺成品。冷床的設計質量與安裝精度直接決定著產品的終質量。

The cooling bed feeding device collect group sent to the output roller, the roller output will be sent to the cold shear into thespecified product. Design quality and installation accuracy of cooling bed directly determines the final quality of the product.

冷床是軋鋼生產中重要的輔助設備。冷床的作用在于將800℃以上的軋件冷卻到150～100℃以下，同時使軋件按既定方向運行，在運輸過程中應保證軋件不彎曲。由于軋制產品形狀繁多相差懸殊，因此，軋鋼車間的冷床型式是多種多樣的。

The cooling bed is an important auxiliary equipment in steel rolling production. The bed is 800 degrees above the workpiece cooling to 150~100 DEG C, and make the operation according to the established direction, in the transport process should ensure the workpiece does not bend. Because the rolling shape of the product range of disparity, so the type of cooling bed steel workshop are diverse.

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.

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掛鉛、掛鹽現象。

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.
