Description of Z3 BMP Prepainted Rolled Steel Coil for Construction

Cold rolled steel coil is steel that has been worked below its recrystallization temperature by passing it between a pair of rollers. Recrystallization temperature is the temperature at which grains in the lattice structure of the metal have been rearranged, leaving it free of strain and deformations. Cold rolled steel coil is pre-treated before being cold rolled with a process known as pickling, which uses strong acids to remove scale and other impurities. The cold rolled steel coil is then passed through rollers to reduce its thickness. Most cold rolling takes place in multiple passes and as the size of the cold rolled steel coil is further reduced, its strength and hardness both increase, but its ductility decreases. After cold rolling, heating the metal up in a process known as annealing can restore some of its ductility. The final cold rolled steel coil may be manufactured in the form of sheets, strips, bars, or other forms.

Q:Aluminum alloy rolling doors and color steel shutter door that good
Aluminum Alloy shutter door instead of the traditional rolling door noise inherent shortcoming, the process of opening and closing of windleavesthe sound {(Note: the design of Aluminum Alloy shutter doors from the beginning not to seal, but the curtain sheet with a silencing strip sealinghas been improved, but still did not have the seal. ) the existing Aluminum Alloy shutter door curtain film have two Aluminum Alloy hollow extrusions and Aluminum Alloy filled polyurethane foam materials, extrusiontypecurtain, hardness, making width, protective performance are better than the filling profiles, in accordance with the free choice profile door curtain sheet to the different needs of users.
Q:What's the difference between hot rolled coil and hot-rolled carbon thin steel coil?
Hot rolled coil is used for continuous casting slab or as raw material, after reheating furnace heating, descaling into the roughing mill of high pressure water, roughing material by cutting head, tail, and then enter the finishing mill, the implementation of the computer controlled rolling, after finishing through the laminar cooling (computer controlled cooling rate and coiling) reel, a straight hair volume. Hair straightenerrollhead, tail tongue shapeand thefishtail shape, thickness, width of poor accuracy, edgehaswavy, folding, tower and other defects. The volume is heavy. (general management industry likes to use. )
Q:In the warehouse management system of steel coil
Warehouse is an important component of enterprise material supply system. It is also the tache of enterprise material circulation and storage, and it also undertakes many functions of material management. Its main tasks are to keep the stock well, to be accurate, to be of good quality, to ensure safety, to prompt the people, to produce, to be considerate, to reduce costs, and to speed up capital turnover.
Q:Several reading methods of steel tape measure
Precise steel tape factory and after a period of time must go through the verification and indicate the verification of temperature, tension and feet. Feet marked on the length of its nominal length, and the difference between the actual length is called length correction delta l ruler by different tension will make feet long. To avoid this change requires the use of steel tape according to the scale mark force of steel tape. At different temperature the foot will change with the temperature so it is necessary to use t as variable function to represent the feet long, this is the ruler length equation, its general form:
Q:Cold rolled steel coil steel, what is the difference?
Steel rolling process is different from the steel produced naturally different!
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:A roll of 1 meters wide color steel roll about how many tons?
Color steel roll is a composite material, both steel and organic materials, both of them a little. Both the mechanical strength of steel plate and easy molding performance, but also organic materials, good decoration, corrosion resistance. 1 meters wide should also have length, wall thickness conditions to know how many tons. The manufacturer is generally in accordance with customer requirements into a volume, the normal width of 1 meters per roll over 1 tons.
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:How are steel tape measures installed?
Today, I met similar situations at work! Accidentally pull the head, and then automatically can not go back, after opening, winding, after installation, can not automatically withdraw! After a long time, we suddenly noticed that we neglected a small place!
Q:What's the length of a coil of cold rolled steel? Is there a standard?
And the length has a lot to do with the thickness. So the total length of the volume is not good.
