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:What gas does the shear of the strip weld require for the welder?
(1) inlet strip clamping mechanism.(2) shearing machine.(3) welding device.(4) export strip clamp mechanism.The inlet and outlet strip clamp mechanism is used to make the end of the strip to the middle and clamp to the welding position, including strip clamping, centering and positioning device.
Q:Is the strip steel strip?
Some thicker medium plate production is not produced by strip steel. In any case, the strip is a general term for strip and plate.
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:Causes of zinc removal in hot rolled strip
The Al content in the alloy layer is little, and the Fe2Al5 alloy layer which is decisive to the adhesion of the zinc layer is not generated, or the alloy layer is damaged by the excessive growth of the iron zinc alloy layer.
Q:Can cold rolled strip be plated with white zinc?
Sure。 Electroplating cold rolled plate surface is gray rust, after plating the cold rolling plate smoothness is higher than that of hot rolled plate.
Q:The relation between hot rolled strip and cold rolled coil, hot rolled strip and cold rolled strip
The hot rolled coil is made of slab (mainly continuous billet), and is made of roughing mill and finishing mill after heating. The hot strip from the last mill at the end of the finishing mill is cooled by laminar flow to the set temperature. The coiler is rolled into a coil and the cooled strip is rolled.
Q:What are the advantages of cold rolling and cold rolling strip steel?
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.
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.
