an appropriate choice of venue and the Treasury
Custody of the steel site or warehouse, should be clean, unobstructed drainage away from the factories and mines produce harmful gases or dust. Presence on the ground to clear weeds and debris, to keep the steel clean.
2, shall not be in a warehouse for steel with acid, alkali, salt, cement and other aggressive materials stacked together. Different varieties of steel should be stacked separately, to prevent confusion and to prevent contact corrosion.
Large steel rail, the shame of steel plate, large diameter steel pipe, forgings, etc. can open dumps.
4, small and medium-sized steel wire rod, rebar, the diameter steel pipe, steel wire and wire rope, etc., can be stored in well-ventilated material shed, but it must thatch Xiadian on.
5, a number of small steel, steel sheet, strip, silicon steel, small-diameter or thin wall steel pipe, all kinds of cold rolled steel and the price is high, the corrosion of metal products, can be stored storage .
6, the Treasury should be selected according to the geographical conditions, generally use ordinary closed the Treasury, that the roof with walls, doors and windows tight, with the Treasury of the ventilation device.
7, the Treasury sunny pay attention to ventilation, rainy Note Close moisture, often to maintain the appropriate storage environment.
two reasonable stacking, advanced first put
1, the stacking principle requires in the palletizer firm, to ensure safe conditions, so that the varieties, specifications, palletizing, material of different species of palletizing, to prevent confusion and corrosion.
2, against the corrosive effect of the items stored on steel in the vicinity of pile position.
The end of the stack should be padded, sturdy, smooth, to prevent the material damp or deformation.
4, the same material according to storage were respectively stacking, easy to perform advanced starting principle.
, The open dumps of steel, the following must have a wooden pad or of stone, pile surface is slightly inclined to facilitate drainage, and pay attention to the material to be placed flat to prevent causing bending deformation.
6, stacking height, manual operation does not exceed 1.2m, machinery operation does not exceed 1.5m, stack width does not exceed 2.5m.
7, channel, check the Road should be left between the stacks and stacks generally O. 5m of access depending on the material size and the transport machinery, general 1.5 ~ 2.Om.
, Stack the end of the booster, if the concrete floor warehouse for the sunrise, booster O.1m to; the case of mud required to elevate O.2 ~ 0.5m. For open space, concrete floor booster O.3 ~ O.5m, sand and mud surface booster 0.5 ~ O.7m.
9, open dumps angle and channel should be overlooking the discharge, ie, mouth down, the beam should stand up, steel I-groove face up to avoid stagnant water to rust.
three, to protect the materials of the packaging and the protective layer
Preservative coating in the steel mills before leaving the factory, or other complex plating and packaging, which is an important measure to prevent the corrosion of materials, transport loading and unloading should be noted that protection can not be damaged, extend the retention of the material.
four, to keep the warehouse clean and strengthen the material conservation
1, the material in storage before to pay attention to prevent rain or mixed with impurities, wipe have been exposed to rain or soiled materials using different methods according to their nature, such as high hardness of the available wire brush. The low hardness with cloth, cotton, and other objects.
Material storage should always check, if rust, corrosion layer should be clear.
3 steel surface clear in the net, and do not need oiling, but need to be coated with anti-rust oil of high quality steel, alloy steel sheet, tube, alloy steel tube, rust inside and outside surface and then stored.
More serious corrosion of steel, rust should not be long-term storage, as soon as possible.
