Q:Cold rolled steel coil steel, what is the difference?
Cold: hot rolled steel coil as raw material by pickling descaling after cold rolling, the finished rolling hard volumes, due to continuous deformation caused by cold hardening the volume rolling hard strength, hardness, toughness index rise decline, so the stamping performance will deteriorate, only for a simple deformation of parts. Rolled hard rolls can be used as raw material for hot galvanizing plants. Because the hot galvanizing units are equipped with annealing lines, the steel coils are rolled continuously at room temperature. Its strength is very high, but toughness, weldability is slightly worse, bright surface, not easy to corrosion, in order to prevent rust, the factory surface is coated with a protective layer of oil (hot rolling did not). Because of the complexity of the process, the price is higher.
Q:Can cold rolled galvanized steel coils be acid washed after oxidation?
If it has been galvanized, it can not be pickled, and if it is pickled, it may corrode the zinc layer
Q:Measures to prevent cold rolling of packaged cold rolled steel coils? Who can give some professional opinions oh?
Cold rolled steel coils are generally sprayed antirust oil, according to user requirements, light, medium, heavy oil 3 types. Nevertheless, if the oil is volatile or in a humid environment, the steel plate comes into contact with the water for a period of time, indicating that it is beginning to rust.
Q:Where do I need hot galvanized steel coils and color coated rolls?
In industrial or coastal areas, due to the influence of sulphur dioxide or salt in the air, the corrosion rate is accelerated and the service life is affected. In the rainy season, the coating has been soaked by rain for a long time, or the temperature is too large and easy to dew. It will be corroded quickly and the service life will be reduced. A building or building made of colored coated steel plates, often with a long service life when washed by rainwater, otherwise affected by sulfur dioxide, gas, salt, and dust. Therefore, in the design, if the roof slope is greater, the more difficult to accumulate dust and other dirt, the longer the service life; for those areas or parts that are not often washed by rain water, should be regularly washed with water.
Q:Why can't the coil weight be too low?
And may make the level stacked steel coil collapse, rolling, produce production safety accidents.
Q:How can the outer diameter and weight of steel coil be converted?
Of course, the calculation is relatively coarse, and the volume has a lot to do with the tension.
Q:Aluminum alloy rolling doors and color steel shutter door that good
Among them, aluminum alloy rolling doors and ordinary rolling doors, both from the appearance, environmental protection or safety, have considerable advantages. Aluminum Alloy doors can be sprayed on the surface of various colors and patterns, but also with the concavity of the wood, sand grain coated, highlight the noble temperament, improve grades, if it is used in shops, you can let your talent shows itself in many shops in the.
Q:The strip tower height
Definition and appearance: the ends of the steel coils are uneven, one circle higher than the circle, showing a different degree of pagoda shape or bread shape.
Q:What's the length of a coil of cold rolled steel? Is there a standard?
Generally, according to the volume measurement, each roll weighs 3~15 tons.
Q:Is a steel plate the same as a steel coil?
Generally speaking, they can be used interchangeably, and the purchase price of the plate is slightly cheaper.
