Q:What are the characteristics of cold rolled strip technology?
Cold rolled blank because the surface covered with oxide film and a small amount of impurities, will directly affect the precision of rolling and the quality of the product, so the blank material must first sent to the shallow groove company push-pull continuous pickling, pickling of oxide film and annealing to remove impurities, can be sent to the high precision six roller reversible rolling mill made the required thickness. After rolling through forced circulation cover type bright annealing furnace and high precision leveling unit two Kun to soften and smooth surface, and then finished packing or according to customer demand straight points, finally packaging factory.
Q:What's the difference between cold rolled strip and cold rolled strip?
Cold roll is usually called hard roll, 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:What are the differences between strip steel and round steel? Where are they mainly used?
Strip steel is widely used in the production of welded steel pipe, made of cold formed steel billet, manufacturing bicycle frame, rim, clamp, gasket, spring, saw blades, hardware and blades.
Q:What's the difference between strip 235 and 235b?
235B only requires a temperature environment of 20 degrees C; this is because of their chemical composition of sulfur, S, phosphorus, P content indicators caused by different.The 235 is 235A, 235 in the material according to the sulfur phosphorus content from high to low is divided into ABCD four grades, grade a sulfur phosphorus was the highest relative performance (welding, plasticity) is the worst, D performance is the highest, the lowest content of parathion.
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?
Thinning is related to width. But after a certain width, the amount of thinning has little to do with the width. The theory of hot rolling can be rolled to 0.8mm, and in practice, the 1.2mm is virtually useless.
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 are the advantages of cold rolling and cold rolling strip steel?
Cold rolled steel strip and sheet thickness is generally 0.1 ~ 3mm, width 100 ~ 2000mm in hot strip steel or timber as raw material, under normal temperature after cold rolling, cold rolled steel strip and sheet has the advantages of smooth surface, smooth, high precision and good mechanical properties.
Q:The degreasing time is too long, will the strip surface be oxidized?
Sheet metal pretreatment, degreasing total alkalinity is recommended in 15-20, alkali spent large, must be short time processing, for a long time will make the metal crystal nucleus passivation, influence phosphating film. Sheet metal general oil should not be cleaned, especially stamping parts, etc., it is recommended to use degreasing temperature, the temperature can be 65-75 degrees.
Q:What's the reason for the strip after pickling?
Will it use a strong acid wash, and the temperature is too high to destroy the ductility of steel?.
Q:What does "strip 50" mean?
Medium carbon high strength carbon steel, after quenching with high strength and hardness of the steel cutting medium, cold plastic deformation, poor welding, heat treatment when no temper brittleness, but the hardenability is low, the critical diameter of water is 13*30mm, and when the water quenching cracking tendency. This steel is usually used after normalizing or quenching, tempering, or high frequency surface hardening.
