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?
The term "steel coil" is strip steel whose width is greater than 600mm and its width is less than 600mm. It is called "narrow band", so hot rolled coil is called hot rolled strip steel. As for the difference between hot rolled coil and cold rolled sheet, it is aimed at the rolling state of the steel plate. The hot rolled coil is made by rolling the hot rolled slab.
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:What is the difference between cold plate and strip steel?
Strip steel is a kind of narrow and long steel plate produced by various rolling mills 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.
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 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.
Q:What about the strip scraping in the annealing furnace?
Thus forming an air knife scratch. This kind of defect causes the product to be wasted because the coating is scratched. Proper control of strip tension in productionForce and adjust the nozzle distance, can avoid this kind of defect happen.
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:Hot rolled strip and hot rolled strip are also sealing plates? What's their function?
Secondly, strip and steel strip should be about the same, no less than a narrow strip of steel bar, the equipment configuration is the same
Q:How to drill through galvanized steel strip quality piercing eye
The quality of the strip is not good, quality is not good, which made galvanized pipe, can not bend 90 degrees, depending on the quality of the strip material; general material, galvanized can be plated well.
Q:65 what is the hardness of the best heat treatment of manganese steel strip?
65, the optimum heat treatment hardness of manganese strip depends on the application and heat treatment method;1, 65Mn strip at 850 degrees Celsius, quenching oil +180 degrees, low temperature tempering 6 hours, hardness can reach HRC56 or so.2, if it is 400 degrees Celsius, tempering 4 hours, its hardness is generally around HRC39.
