Product Description:

1.Structure of Cold Rolled Steel Description

With hot rolled steel coils as raw material, after acid pickling to remove oxide skin for cold rolling, the finished product is hard, because of cold work hardening caused by deformation of continuous cold rolling hard roll strength, increase hardness, toughness and plastic index decreased, so the stamping performance will deteriorate, can only be used for simple deformation of the parts.Hard coil can be used as a raw material, hot dip galvanized factory for hot dip galvanizing unit Settings are annealed wire.Hard coil weight generally in June to 13.5 tons, coil diameter is 610 mm. 

2.Main Features of the Cold Rolled Steel

1, higher precision, cold-rolled strip steel thickness difference of no more than 0.01 ~ 0.03 mm.
2, the size is thinner, cold rolling the thin steel strip rolling 0.001 mm;Hot rolling can reach 0.78 mm the thinnest now.
3, the surface quality is superior, cold rolled steel sheet can even produce the mirror surface;While the surface of hot rolled plate tin oxide, such as pitting defects.
4, can manufacture according to customer requirements to adjust its properties such as tensile strength and process performance such as stamping performance, etc.
Cold rolled and hot rolled is two different types of steel rolling technology, as the name implies, is cold rolled copper under the condition of steel at room temperature, the hardness of the steel.Copper is hot rolled steel in high temperature circumstances.

Q:Aluminum alloy rolling doors and color steel shutter door that good
The material and structure design Aluminum Alloy rolling shutter door out of the ordinary, can effectively prevent glare and ultraviolet radiation, sunlight greenhouse effect on indoor has completely solved, applicable to all kinds of changes in climate and weather, has a long-term protective effect on indoor environment, tests show that the shutter doors and windows to keep out sunshine rate to 100%, the the rate can reach more than 95% block temperature.
Q:What are the characteristics of hot-rolled steel coils and cold rolled steel coils? What loading and unloading tools should be used? What items should be paid attention to?
When placing materials to roll on both sides of the main pad wood pallets, prevent rolling back and forth. In addition the floor should be thickened, cannot have uneven or debris, because the line of steel coils when gravity concentrated in contact with the ground floor, there is a fracture easily, debris, easy to leave the indentation in the steel roll.
Q:What is the material of steel coil 08F and what brand can be used instead?
20 steel used for various mechanical parts is not subjected to great stress and toughness, such as rod, sleeve, screw, lifting hook; also can be used for manufacturing in 60 pressure and 450 DEG C using non corrosive medium pipes, pipe; can also be used for carbon and cyanide carburized core strength is not the chain, such as bushings, roller, shaft and gear, sprocket and other important.
Q:On how to reinforce steel coils in a container
In the bottom and sides with a thick strip stuck, but also to ensure that the wood will not loosen down...... Rough steel rolls, I saw people loading and unloading on the docks, poked them directly with a small forklift truck, and then reinforced with wooden planks
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: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:What is the accuracy of steel tape inspection
In addition, the project is through the detection of steel tape, steel tape each batch have the error him different, so do projects each into a batch of steel tape has to go through the inspection department, let this batch of steel tape has reached the same error range. All the measuring tools in this project are unified into these steel tape measures, so that the measurement error is guaranteed
Q:What is the difference between a steel strip and a coil? The steel strip is flat steel, and the steel coil is made of steel.
Steel rolls are also called steel belts. There is no difference between them. They are not flat steel
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:What is the difference between cold rolled strip and cold rolled steel coil?
Cold rolled steel strip: the width is below 900mm! Cold rolled steel coil: the width is above 1000mm! Materials and purposes are not very different, basically the same!
