球墨铸铁井盖表层的清理要注意什么?

来源:http://www.macyplace82.com添加时间:2021-10-15 15:23:23

长期性安裝后,由生铁球墨铸件做成的手孔遮盖了风和太阳,因而外界当然存有尘土和空气污染物,因而表层上看上去像尘土,刮痕和锈迹。大家应当怎样等候并保持干净?

After long-term installation, the hand hole made of pig iron ductile iron casting covers the wind and sun, so there are dust and air pollutants outside, so the surface looks like dust, scratches and rust. How should we wait and keep clean?

1.转动铸孔盖表层的尘土

1. Turn the dust on the surface layer of the casting hole cover

铸钢件下水井盖常常在多尘的地区生产制造,空气中常常有很多尘土,而且一直坠落在机器设备表层。能够自来水或碱性溶液将其去除。可是,假如累积了尘土,则必须髙压水或蒸气开展清理。

Steel casting manhole covers are often manufactured in dusty areas. There is often a lot of dust in the air, and it has been falling on the surface of machinery and equipment. It can be removed with tap water or alkaline solution. However, if dust is accumulated, it must be cleaned with high-pressure water or steam.

2.球墨铸铁井盖表层浮粉丝或内嵌式铁

2. Floating vermicelli or embedded iron on the surface of nodular cast iron manhole cover

在每一个表层上,分散铁都是会锈蚀并浸蚀不锈钢板。因而,务必消除它。空气中的粉末状一般可以用尘土消除。一些键十分坚固,务必将其视作置入铁。除烟尘外,用一般碳素钢钢刷清理并且用夹层玻璃,珠串和之前用以一般碳素钢,高合金钢或生铁人孔盖等的别的耐磨材料开展抛丸除锈清除。表层铁有很多来源于。以上非球墨铸铁井盖,将在盖的周边,而且不锈钢板的手孔的机器设备来碾磨。假如在落料或提高全过程中不维护不锈钢板,则工作中表层上的镀锌钢丝绳,吊装工具和铁非常容易置入或搞脏表层。

On each surface, the dispersed iron will rust and etch the stainless steel plate. Therefore, it is important to eliminate it. Powder in the air can generally be eliminated by dust. Some keys are very strong, so be sure to treat them as iron. In addition to the dust, the general carbon steel brush shall be used for cleaning, and the laminated glass, bead string and other wear-resistant materials previously used for general carbon steel, high alloy steel or pig iron manhole cover shall be used for shot blasting. There are many sources of surface iron. The above non nodular cast iron well cover will be ground around the cover and the hand hole of stainless steel plate. If the stainless steel plate is not maintained in the whole process of blanking or raising, the galvanized steel wire rope, hoisting tools and iron on the surface layer are very easy to be placed or dirty.

3,球墨铸铁井盖上的刮痕

3. Scratches on nodular cast iron manhole cover

划痕和别的不光滑表层务必开展机械设备清理,以避免全过程润滑液,产品和污渍沉积。

Scratches and other non smooth surfaces must be cleaned by mechanical equipment to avoid the deposition of lubricating fluid, products and stains in the whole process.

4.球墨铸件除锈迹

4. Rust removal of nodular cast iron

球墨铸铁井盖或机器设备在生产制造以前或生产过程中很有可能锈蚀,这说明表层已被比较严重环境污染。在应用机器设备以前,务必消除锈迹。应应用铁或水检测查验完全清理的表层。

Nodular cast iron manhole covers or machinery and equipment are likely to rust before or during production, indicating that the surface has been seriously polluted by the environment. Be sure to remove rust before applying machinery and equipment. The completely cleaned surface shall be examined by iron or water testing.

5,精磨生产加工

5. Fine grinding production and processing

切削和机械加工制造均会造成不光滑的表层,并含有例如管沟,重合和毛边这类的缺点。每一个缺点还会继续将金属表层 毁坏到一定深层,进而避免根据酸洗钝化,电抛光或喷丸处理清理损伤的金属表层 。不光滑的表层很有可能会造成 浸蚀和堆积物质。在除去再次焊接以前要清除焊接缺点,不然不能用不光滑的切削来打磨抛光过多的焊接。后面一种状况下,务必应用细耐磨材料对其开展打磨抛光。

Both cutting and machining can cause an unsmooth surface and contain defects such as pipe trench, overlap and burr. Each defect will continue to destroy the metal surface to a certain depth, so as to avoid cleaning the damaged metal surface according to pickling passivation, electropolishing or shot peening. An unsmooth surface is likely to cause erosion and accumulation of material. Remove welding defects before removing re welding, otherwise excessive welding cannot be polished by unsmooth cutting. In the latter case, it must be polished with fine wear-resistant material.
