Q:What are the sectors in which galvanized steel strips can be used?
Same as steel plate, strip steel is divided into two kinds of ordinary strip steel and high quality strip steel according to the material used, and two kinds of hot-rolled strip steel and cold rolled strip steel according to processing method. 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. The use of hot galvanized strip is naturally associated with the application of galvanized strip in construction, light industry, automobile, agriculture, animal husbandry, fishery and business. Now, with the improvement of various industries, electronics and other manufacturing processes, the application of materials is also more and more widespread.
Q:What are the categories of strip steel? How do you distinguish it?
Classification by usageAccording to the use of steel, can be divided into structural steel, tool steel, special performance steel three major categories.Structural steel: 1. used as steel for various machine parts. It includes carburizing steel, Quenched and tempered steel, spring steel and rolling bearing steel.2. steel used as an engineering structure. It consists of carbon steel in armour, B, especially steel and ordinary low alloy steel.Tool steel: steel used to make all kinds of tools. According to the use of different tools can be divided into tool steel, die steel and tool steel.Special performance steel: steel with special physical and chemical properties. Can be divided into stainless steel, heat-resistant steel, wear-resistant steel, magnetic steel and so on.
Q:What is the difference between strip and coil?
The strip and the coil is the main raw material for the production of welded steel pipe, the steel pipe manufacturing is mainly manufacturing process for spiral welded pipe used for steel roll uncoiling, leveling, trimming, molding, welding, welded pipe must be used for sheet forming and welding, if the steel roll uncoiling leveling must also be cut into leaflets the use of steel plate.
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?
What to do with cold rolling is better than that of hot rolling, which is the main one because cold rolling is processed by hot rollingCold: 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.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: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.
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 is strip steel?
Compared with steel plate, it has the advantages of high dimensional accuracy, good surface quality and easy to use. Widely used in the production of welded steel pipe, cold formed steel billet, used for the manufacture of bicycle frame, wheel, clamp, gasket, spring, cable armored, saw blade, blade, packing iron sheet and so on.
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.
