泰州SKF轴承61809-2Z冷轧流水线的热处理方式

冷连轧可以获得均匀的壁厚，这是保证螺距精度和均匀性的重要条件。套筒内外表面的圆度可由精整机很好地控制，保证套筒与链板的**佳匹配。表面硬化技术使套筒杏面膜具有较高的耐磨性，而泰州SKF轴承内层具有较高的韧性和抗冲击性。细磨使套筒具有更长的耐磨寿命。

Uniform wall thickness can be obtained by continuous cold rolling, which is an important condition to ensure pitch accuracy and uniformity. The roundness of inner and outer surface of sleeve can be well controlled by finishing machine to ensure a good match between sleeve and chain plate. The surface hardening technology makes the sleeve apricot mask h***e high wear resistance, while the inner layer of Taizhou SKF bearing has high toughness and impact resistance. Fine grinding makes sleeve h***e longer wear-resistant life.

链条采用冷挤压棒材实心辊，具有优良的抗*疲劳性能和高冲击负荷性能。所有轧辊均经硬化处理，具有良好的耐磨性。为了避免裂纹的扩展，采用喷丸处理提高轧辊的疲劳强度，从而提供必要的保护。

The chain adopts cold extruded bar solid roll, which has excellent anti-fatigue performance and high impact load performance. All rolls are hardened and h***e good wear resistance. In order to ***oid crack propagation, shot peening is used to improve the fatigue strength of rolls, thus providing necessary protection.

采用***的自动化设备对零件进行装配，实现正确的间隙，使链条具有精*确的节距和完*美的配合。每个零件及其加工**须经过严格的质量控制和定期检查，以确保泰州SKF轴承满足要求的公差和标准。我们将根据客户的不同要求提供各种防腐处理和防腐处理。

The parts are assembled with advanced automation equipment to achieve the correct clearance, so that the chain has precise pitch and perfect coordination. Each part and its processing shall undergo strict quality control and regular inspection to ensure that Taizhou SKF bearings meet the required tolerances and standa***. We will provide all kinds of anticorrosive treatment and anticorrosive treatment according to the different requirements of customers.

预拉伸装配链记录关闭车道和消*除初始拉伸。提高了塔链的抗*疲劳性能。

Pre-stretching assembly chain reco*** closing lanes and eliminating initial stretching. The fatigue resistance of tower chain is improved.

插入后，链条被预润滑以在初始操作后提供润滑。另外，预润滑还可以防止生锈，延长链条彗星的使用寿命。

After insertion, the chain is pre-lubricated to provide lubrication after initial operation. In addition, pre-lubrication can also prevent rust and prolong the service life of chain comets.

（1）注意工件的放置，确保均匀加热，防止过热。在使用燃气炉或天*然气炉时，注意不要用喷嘴或火焰直接加热工件。

(1) Pay attention to the placement of the workpiece to ensure uniform heating and prevent overheating. When using gas or natural gas furnaces, be careful not to use nozzles or flame to directly heat the workpiece.

（2）应慎重引进进口泰州SKF轴承和细长杆，防止变形。

(2) Imported Taizhou SKF bearings and slender rods should be carefully introduced to prevent deformation.

(3)当完全退火时，通常中小型碳钢和低合金钢工件可以直接装入退火温度炉而不用控制加热速度，或者可以在低温下装入炉内并在炉内使用。对于形状复杂的中、高合金或大型零件，低温分段加热的加热速度不超过100C/h。

(3) When annealed completely, usually ***all and medium-sized carbon steel and low alloy steel workpieces can be directly loaded into the annealing temperature furnace without controlling the heating speed, or can be loaded into the furnace at low temperature and used in the furnace. For medium, high alloy or large parts with complex shape, the heating speed of low temperature sectional heating is not more than 100C/h.

(4)大型工件的应力消*除退火应在低温下进行，并缓慢加热，以防止过热引起的热应力。

(4) Stress relief and annealing of large workpieces should be carried out at low temperature and heated slowly to prevent thermal stress caused by overheating.

（5）正常化和空冷时，应尽可能平坦。无论哪种工件都是风冷的，都应该分散在干燥的地方。它不应该堆叠或重叠。不应湿或湿，以确保均匀的冷*却速度和均匀的硬度。斗篷。

(5) When normalizing and air cooling, it should be as flat as possible. No matter which kind of work piece is air-cooled, it should be dispersed in a dry place. It should not be stacked or overlapped. It should not be wet or wet to ensure uniform cooling speed and uniform hardness. Cloak.

(6)材料不同，但泰州SKF轴承加热温度相同的工件可以在同一炉内加热。

(6) The materials are different, but the workpiece with the same heating temperature of SKF bearing in Taizhou can be heated in the same furnace.

（7）对于截面尺寸不同的工件，在同一炉内加热时，应在炉外放置小零件。

(7) For workpieces with different cross-sectional sizes, when heating in the same furnace, ***all parts should be placed outside the furnace.

(8)一般情况下，水温不超过40℃，油温不超过80℃。

(8) Generally, the water temperature does not exceed 40 C and the oil temperature does not exceed 80 C.
