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:How does the disc shear deal with the problem of side clips into the strip?
His main function is the wide strip strip along the length direction of cutting into a certain size narrow roll for rolling, after the pipe, cold roll forming and stamping blank preparation. At the same time, the replacement of different materials of cutting tools can be divided into a variety of non-ferrous metal strip.
Q:Hot rolled strip, the theory of the thinnest, how thin rolling, why not rolling too thin, is the material or the reasons for plate shape?
Tangshan Iron and steel production line design capacity of 0.8mm, the thin can be rolled to 1.8 or limited production, steel level, the purity of molten steel are related, and also there is a certain relationship between the plate width.
Q:Can the tension leveller eliminate the wave shape of strip steel completely?
Reflecting the shape of the board, the wave height is reduced or the wavelength is lengthened. That is, the tension straightener can only reduce the wave and improve the shape of the plate, but can not fundamentally eliminate the wave, and get an ideal smooth strip steel. There is an old saying called "correction must be positive". That is to completely eliminate the wave must be of short fiber than long fiber tension and bending is greater, elastic and plastic deformation of the original long fiber length is greater than a certain amount, resulting in the removal of external force, elastic recovery, length of fiber length, so as to obtain the shape completely flat the. However, in the current conditions of the straightening machine equipment, do not have such a function.
Q:Why is strip heat cheap?
Mainly the production process is not the same.
Q:What's the difference between hot rolled strip and cold rolled strip? What's the difference between hot rolled coil and cold rolled coil?
Hot rolled coil is above the recrystallization temperature of rolling, cold-rolled plate refers to the recrystallization temperature following rolling, popular point that is in the hot strip rolling red hot state, while cold rolled hot-rolled is under normal temperature rolling. Hot plate often said refers to the hot rolled plate, cold plate refers to the cold rolled plate, hot rolled, cold rolled and hot rolled coil is said and cold rolled coil.
Q:Causes of zinc removal in hot rolled strip
The residual impurity particles on the substrate surface are not removed before immersion into the zinc pot, which affects the adhesion of the zinc layer.
Q:How to distinguish cold strip steel and cold rolled silicon steel sheet by simple and practical methods
First of all, from the thickness of silicon steel sheet are below 0.5MM and 0.5MM.
Q:What's the cutting edge of cold rolling strip?
Cold rolled materials are generally cut edges. The hot rolled material is partly rough. Cutting edges and burrs can be viewed straight. The two sides of a strip of steel, similar to those of waves. The two sides of the trimming are straight.
Q:What does "strip 50" mean?
It is a kind of narrow and long steel plate produced by all kinds of steel rolling mills in order to meet the needs of industrial production of various metal or mechanical products in different industrial sectors. Strip steel, also known as steel strip, is within 1300mm in width, and the length varies slightly according to the size of each roll.
