Q:What's the difference between cold rolled strip and cold rolled strip?
The term "steel coil" is strip steel, whose width is less than 600mm. It is called "narrow band", so cold rolled coil is called cold-rolled strip
Q:What is galvanized steel strip? What's the difference between galvanized strip and cold rolled strip?
Galvanized steel strips are cold-rolled or hot-rolled, long and narrow strip steel plates coated with different layers of material called zinc. Hot galvanizing has the advantages of uniform coating, strong adhesion, long service life and so on.
Q:What is the cause of the deviation of the strip in the rolling process? How to deal with it?
Because of the sudden decrease or disappearance of the tension of coiler during the rolling process, the strip is running off and breaking.
Q:What is the difference between steel strip and strip steel?
In some less strict people, it is easy to confuse these two names, but also on the Internet with the same strip of steel.
Q:What is the difference between strip and coil?
Coil generally refers to the strip width not less than 600mm, can generally be divided into Kaiping steel plate or longitudinal strip, standard and plate together, such as: carbon and low alloy structural steel plates and strips. Strip width is generally less than 600mm.
Q:What about the strip scraping in the annealing furnace?
When the plate shape is not good, the strip tension is too low or the nozzle is too close to the strip, it may cause the contact between the nozzle and the strip,
Q:What's the cutting edge of cold rolling strip?
Do you mean the cutting edge is the indication of the steel roll out of the factory? When the steel factory leaves the factory, the steel coil will have the burr and the cutting edge two kinds, the rough edge is the steel strip two, the edge is not neat. The trimming is the two sides of the steel band, and the width of the strip is certain when it is trimmed.
Q:What is the meaning of C hot strip material, B material is how to distinguish between
Due to work hardening of cold rolled steel plate, a certain degree of toughness is low, but can yield better than that used to cold spring piece parts, at the same time as the yield point is close to the tensile strength, so the use of risk is not predictable, prone to accidents in the load exceeds the allowable load.
Q:What is the difference between strip steel and silicon steel?
Silicon steel is a silicon iron alloy with silicon content of about 3%~5% and other major iron. Divided into oriented silicon steel and non oriented silicon steel, it is an important soft magnetic alloy in electric power, electronics and military industry. Silicon steel refers to a low carbon silicon iron alloy with silicon content ranging from 0.5% to 4.5%. It is divided into non oriented silicon steel and oriented silicon steel because of its different structures and uses. Silicon steel is mainly used as the core of various motors, generators, compressors, motors and transformers. It is an indispensable raw material for electric power, household appliances and other industries.
Q:Specification and use of cold rolled strip
Advantages of cold rolled strip:A very thin strip of steel (0.001mm), which is difficult to obtain by hot rolling method, can be obtained;It can make the product have high mechanical properties and wide range of performance;Guarantee to obtain the high precision size, the thickness deviation is small, along the strip width and the length aspect uniformity, the shape is good, the surface is bright and clean each kind of strip steel;Low cost and high efficiency;Rolling speed, with high productivity.Technological characteristics of cold rolled strip:When the strip is rolled in cold condition, because of the hardening of the strip, the intermediate annealing must be done to soften it and restore the plasticity so as to continue rolling;The surface iron oxide scales must be removed before rolling, thus ensuring the surface smoothness of the strip and reducing the wear of the roll;Adopting tension rolling to ensure good strip shape of strip, controlling the deviation of strip thickness and reducing rolling pressure, which is beneficial to rolling thin specification products.Using process cooling and lubrication, it is easy to control the temperature of roller and strip, reduce the friction between roll and strip, and reduce the rolling pressure. It is favorable to shape control and prevent the sticking roll of strip steel.
