通风管道加工时如何增加稳定性？
How to increase stability during the processing of ventilation ducts?
一、大中小型槽钢、盘条、建筑钢筋、中规格无缝钢管、不锈钢丝及镀锌钢丝绳等，可在自然通风优良的料拱棚储放，但务必上苫下垫。
1、 Large, medium, and small-sized channel steel, wire rods, building steel bars, medium specification seamless steel pipes, stainless steel wires, and galvanized steel wire ropes can be stored in well ventilated material arches, but must be covered on top and padded on the bottom.
二、一些中小型钢材、冷轧钢板、钢链、铁氧体磁芯、口径或厚壁无缝钢管、各种各样冷扎、冷拉钢材及其价钱高、易浸蚀的金属制造，可储放进库。
2、 Some small and medium-sized steel, cold-rolled steel plates, steel chains, ferrite magnetic cores, caliber or thick walled seamless steel pipes, various cold-rolled and cold-drawn steels, and their expensive and easily corroded metal manufacturing can be stored and stored in warehouses.
三、存放无缝钢管商品的场所或库房，应挑选在清理整洁、排水管道顺畅的地区，杜绝造成有害物质或烟尘的厂矿企业。到场土里要消除野草及一切脏物，维持钢材整洁。
3、 Places or warehouses storing seamless steel pipe products should be selected in areas with clean and smooth drainage pipes, and factories and mining enterprises that cause harmful substances or smoke should be eliminated. When arriving at the site, weeds and all dirt should be eliminated to maintain the cleanliness of the steel.
四、大中型槽钢、铁轨、辱厚钢板、大口径钢管、铸钢件等能够 室外堆积。
4、 Large and medium-sized channel steel, railway tracks, thick steel plates, large-diameter steel pipes, cast steel parts, etc. can be stacked outdoors.
五、在库房里不可与酸、碱、盐、混凝土等对钢材有黏附性的原材料堆积在一起。不一样种类的钢材应各自堆积，避免搞混，避免触碰浸蚀。
5、 Raw materials such as acids, alkalis, salts, and concrete that have adhesion to steel should not be stacked together in the warehouse. Different types of steel should be stacked separately to avoid mixing and contact erosion.
1、清理
1. Cleaning
运用有机溶剂、溶剂清理钢材外表，以到达除去油、植物油脂、灰尘、光洁剂和类似的有机化合物，但它不可以除去钢材外表的锈、空气氧化皮、焊药等，因此在防腐蚀生产中只做为配合招数。
The use of organic solvents and solvents to clean the surface of steel can achieve the removal of oil, vegetable oils, dust, polishing agents, and similar organic compounds. However, it cannot remove rust, air oxide skin, welding flux, etc. on the surface of steel, so it is only used as a complementary measure in anti-corrosion production.
2、专用工具除锈
2. Special tools for rust removal
主要应用钢刷等专用工具对冷轧通风管道外表开展打磨抛光，能够 除去松脱或翘起来的空气氧化皮、锈迹、焊穿等。手工制作专用工具除锈能到达Sa2级，驱动力专用工具除锈可到达Sa3级，若钢材外表粘附牢固的氧化铁皮
Mainly using specialized tools such as steel brushes to polish and polish the surface of cold-rolled ventilation pipes, it can remove loose or raised air oxide skin, rust, welding penetration, etc. Handmade special tools for rust removal can reach Sa2 level, and driving force special tools for rust removal can reach Sa3 level. If the surface of the steel is firmly adhered with oxide scale
