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:Pickling process of cold rolled strip
Pickling process of cold rolled strip:Strip steel must be pickled before cold rolling, in order to remove the oxide scales on the surface of the steel coil which is harmful to the cold rolling, because the iron oxide sheet will damage the roller surface in cold rolling, and lead to defects on the strip surface. The most commonly used is continuous pickling of strip steel. The advanced cold rolling mill adopts continuous pickling line or Push-pull Pickling at high speed. Taking continuous pickling as an example, pickling is carried out continuously through several pickling tanks. To make the job line process continuous, the front end of a hot strip coil and the rear end of a steel coil are welded together. After pickling, the strip is cut and rolled according to the required roll weight and reel diameter.
Q:What's the meaning of "double light" in strip cold rolling?
Cold: cold rolled steel is cold-rolled steel production. Cold rolling at room temperature under the conditions of No.1 steel plate further rolling thin thickness steel plate. Compared with hot-rolled steel, cold-rolled steel plate thickness is more accurate, and the surface is smooth and beautiful, but also has superior mechanical properties, especially the processing performance because of cold rolled. The volume relatively brittle and hard, not suitable for processing, so typically cold rolled steel demand after annealing, pickling and smooth surface will be delivered to customers. The maximum thickness of cold rolling is below 0.1--8.0MM, most of the factories such as cold rolled steel plate thickness is below 4.5MM; minimum thickness, width is according to the plant equipment capacity and market demand and decision.
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:The degreasing time is too long, will the strip surface be oxidized?
Galvanized steel plate in spray, generally do phosphating treatment, the parameters of free acid phosphating solution should be kept low, and high temperature, acid, zinc ions reduced excessive reaction, resulting in coarse crystallization. Reference: Fa:0.8-1.5 Ta:17-28 acid ratio of about 25, the temperature can be 35-45 degrees.
Q:Why does the strip bend when it is rolled?
The strip will bend after rolling:1) operation reasons, because the operator double pendulum adjustment is unreasonable, resulting in strip deviation.2) electrical reasons, due to the sudden decrease or disappearance of the tension of the coiler during the rolling process, lead to strip deviation and fracture.3) due to roll, roll grinding after serious pressure, taper, makes the school not to the operator in the rolling process of double pendulum regulation increases taper, will cause serious side light waves caused by shape defects, cause strip deviation and broken belt.4) strip edge control device failure, deviation device, tube or mirror surface pollution or other objects covered, so that the deviation of the device failure, resulting in the first line of deviation
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:Is there any difference between galvanized steel strip and galvanized sheet?
Galvanized steel strip, in narrow sense, refers to strips of steel.
Q:Specification and use of cold rolled strip
Cold rolled strip specifications: cold rolled strip and sheet, the general thickness of 0.1 ~ 3mm, width of 100 ~ 2000mm; are hot rolled strip or steel plate as raw material, at room temperature by cold rolling rolling. Grades are generally: SPCC, Q195, Q235-B.
Q:What is the difference between steel strip and coil?
What do you think of rolling mills, not money ah, rolling strip is a small rolling opportunities, can be cheaper than rolling coil, and this cost should be spread to each product above, there are other what, like the cost of sharing ah.
