| 1. Choose a suitable site and warehouse Steel storage site or warehouse, should be selected in the clean, smooth drainage area, away from harmful gases or dust factories and mines. Presence on the ground to clear all the weeds and debris, keeping a clean steel In a warehouse not with acid, alkali, salt, cement, steel and other aggressive materials stacked together. Different types of steel should be stacked separately, to prevent confusion, avoid contact corrosion Heavy sections, rails, shame steel, large diameter steel pipe, forgings can open dumps Sized steel, wire rod, rebar, in diameter steel pipe, steel wire and wire rope, etc., can be expected in a well-ventilated storage shed, but it must be on the thatch underlay Some small steel, sheet, strip, silicon steel sheet, small caliber or thin-walled steel pipes, all kinds of cold-rolled, cold-drawn steel and high prices, corrosive metal products, storage can be stored Treasury should be based on selected geographical conditions, the general ordinary enclosed warehouse, that is the roof with walls, doors and windows tight, with the Treasury ventilation device Treasury requirements sunny attention to ventilation, rain close attention to moisture, and keep proper storage environment 2. Reasonable stacking, advanced first place Principle requires stacking under palletizing firm to ensure safe conditions, so that according to species, palletizing specifications, different varieties of materials to palletizing respectively, to prevent confusion and mutual corrosion Prohibit storage of steel with corrosion of materials near the pile position Stack bottom should be padded, strong, smooth, prevent moisture or material deformation Press the same material were successively stacking storage, facilitate the implementation of the principle of pre-emptive advanced Open dumps steel, the following must be wood or stone pad, pile surface is slightly inclined to facilitate drainage, and pay attention to the material placed flat against deformation caused by bending Stacking height, manual work no more than 1.2m, mechanical work no more than 1.5m, stack width not exceeding 2.5m Should leave some passages between the stacks and stacks, check road and is generally set at 0.5m, of access depending on the size and material transport machinery, is generally 1.5 ~ 2.0m Pile bottom booster, if the warehouse Chaoyang cement floor, to elevate 0.1m; if the mud, shall booster 0.2 ~ 0.5m. If it is open space, concrete floor elevate 0% 26middot; 3 ~ 0% 26middot; 5m, sand and mud surfaces booster 0.5 ~ 0.7m Open dumps angles and channels should stoop to put that mouth down, beam shall stand up, you can not be up and groove steel to avoid rusting water 3. Packaging and a protective layer of protective material Former steel factory applied preservatives or other re-plating and packaging, which is an important measure to prevent the corrosion of materials, loading and unloading in the transport process should be noted that protection can not be damaged, the material storage period may be extended 4. Clean warehouse, reinforcing material conservation Material before storage pay attention to prevent rain or mixed with impurities on the already rain or soiled material to their nature in different ways wipe, such as high hardness available wire brush, low hardness with a cloth, cotton, etc. thing After the storage of materials should always check if any rust, corrosion layer should be removed General steel surface after clearing the net, do not oiled, but high-quality steel, alloy steel sheet, thin-walled pipe, steel pipe, etc., after rust inner and outer surfaces coated with anti-rust oil before storage required After long-term storage of not more serious corrosion of steel, rust should be used as soon as possible. |
