1、滑触线使用前应测量电磁铁冷态绝缘电阻，在室温下其值不小于0.5MΩ。

1, the use of cold insulation resistance measurement of electromagnet, at room temperature and its value is not less than 0.5M.

2、磁铁未平稳地放在被吸物面之前请不要通电工作，严禁将电磁铁做游锤使用。

2, the magnet is not smoothly put onto the material do not please electricity face before, it is strictly prohibited to do swim hammer using electromagnet.

3、电磁铁不宜吊运切料头及废钢，因电磁铁吸力特别大，且电磁铁自重较重，切料头或废钢易冲坏电磁铁底部辐射板。

3, an electromagnet for hoisting cropping and scrap, particularly for electromagnet suction electromagnet, and heavier, cropping or scrap easily washed out the bottom panel.

4、电磁铁应尽可能对称负荷的重心放置。

4, the electromagnet should as far as possible the center symmetry load placement.

1）磁铁的载重量=吸重能力×（1+偏心距/间距），故起重电磁铁之间的间距应略大一些为佳。当两台电磁铁之间间距小而偏心量大时，两台电磁铁的载重量与一台电磁铁的相差无几，工作时会极不安全。对于间距无法扩大的场合，操作时应尽量减少偏心量，使工作安全可靠。

1) magnet weight = lifting capacity * (1+ eccentricity / spacing), so the distance between the electromagnet should be slightly bigger is better. When two electromagnet spacing is small and eccentricity is large, not much difference between the load of two electromagnet and an electromagnet, will be extremely unsafe work. For the distance is difficult to expａnd the occasion, the operation should be to reduce the offset, the safe and reliable operation.

2）对于不易产生绕度的较长钢材，电磁铁的负重较大，一般采用多台联用。采用这种方式，吸附面的水准是相当重要的，宜采用天平式两层横梁吊架。除特殊原因外，多采用四台电磁铁联用，这样对吊链之类的精度要求要小得多，便于实际当中调试和使用。

2) for not easy to produce long steel around, electromagnet bearing large, generally adopts multi Tsu use. In this way, the adsorbing surface level is very important, should adopt the balance type two beam hanger. Except for special reasons, the four magnet combined with, so to chain like precision is much smaller, and use the debugging is convenient for practical.

3）当采用超过四台电磁铁联用吊运时，电磁的吸附面应仔细调整以适应实际工况，否则会出现个别电磁铁不但不起作用，而且还将自重加上，增加其它电磁铁的负担。

3) when using more than four sets of electromagnet with lifting, the adsorption surface electromagnetic should be carefully adjusted to the actual condition, can appear otherwise the individual electromagnet not only play a role, but also the weight and increase the burden of other electromagnets.

5、两台联用时其间距为物料长度的一半。

5, two with the distance of half the TSU material length.

6、要求用高温电磁铁吊运高温物料，用常温电磁铁吊运常温物料，严禁用常温电磁铁吊运高温物料。

6, high temperature electromagnet is used to transport material with high temperature, room temperature lifting magnet material at room temperature, prohibit the use of room temperature lifting magnet high temperature materials.

7、严禁将电磁铁停留在高温物体上等待。高温电磁铁在被吸物温度降到600℃以下方可将电磁铁靠近工作，超高温电磁铁在被吸物温度降到700℃以下方可将电磁铁靠近工作。

7, it is strictly prohibited to stay in high temperature object for electromagnet. The high temperature magnet in the absorbate temperature dropped to 600 ℃ below will be the electromagnet work, ultra high temperature magnet in the absorbate temperature dropped to 700 ℃ below will be close to the work.

8、不使用时，不得使电磁铁在高温区停留、徘徊、存放。

8, when not in use, may make the electromagnet stay in high temperature area, wandering, storage.

9、尽量缩短电磁铁和高温物体接触的时间。

9, try to shorten the contact time between electromagnet and high temperature materials.

10、低通电率电磁铁不能作高通电率产品使用，必须根据具体情况选用相应通电率的电磁铁。

10, low electricity electromagnet can not make high power rate of product use, must be selected according to the specific situation of electromagnet corresponding electricity rate.

11、对于超高温电磁铁在使用过程中若出现吸力明显下降或磁极过热时，应让电磁铁休息一段时间，或将电磁铁磁极浸泡在深度为300mm的水坑中冷却。

11, for the ultra high temperature electromagnet in use process, if the suction decreased or pole overheating, should make the electromagnet to rest for a period of time, or will the electromagnet magnetic immersion cooling at a depth of 300mm in the water.

12、电磁铁随着起重机的升降，要避免砸断和拉断电缆。

12, an electromagnet with the crane lifting, to avoid cut and pull off cable.

13、在运行中要定期观察电磁铁控制屏上电压、电流指示值。电磁铁的励磁电流应处于冷态电流和热态电流之间。电压允许误差不超过±10%。

13, in the operation to regularly observe the magnet control voltage, current screen indicator. The excitation current of the electromagnet shall be in the cold current and the hot current. Voltage allowable error is less than ± 10%.

14、电磁铁应保持干燥，使用完毕后，应放在干燥、通风、无有害物质处。

14, the electromagnet should keep dry, after use, should be placed in dry, ventilated, without harmful substances.

15、经常检查链条、销轴的磨损情况。

15, often check the wear chain, pin.
