General Information of Cold Rolled Steel Sheet

The raw material of cold rolled steel sheet is high quality hot rolled product, and after pickling, continuous rolling, degreasing, annealing, skin pass, slitting and cut to length line etc. Along with it many kinds of new technology and new process of global cold rolling production have been applied. Therefore the quality of the goods could be guaranteed. The finished product has a variety of excellent capabilities, such as processing capability and smooth, flat surface. It’s widely used in outdoor and interior decoration, furnishing manufacturing, home appliance, automobile etc.

Q:What kind of material does ordinary steel plate refer to in steel market?
Wear resistance and special electromagnetic properties, carbon steel in this respect is relatively poor, because in the manufacture of this kind of steel plate, often to maintain good toughness, so we reduced the iron element to join. Not as a result of the steel sheet in abrasion resistance and special electromagnetic aspects is very weak, but the alloy plate is different because adding other alloying elements, which makes the original in iron deficiency situation has been greatly improved this is better for some special requirements of customers.
Q:What's the material of ASTM A653 G30 galvanized sheet?
American standard galvanized steel sheet with a coating thickness of 0.3 ounces per square inch. General material specifications, you can also james.
Q:How is the normalized steel plate produced?
The main purpose of normalizing is to refine the structure, to improve the properties of the steel, and to obtain a structure close to the equilibrium state. Compared with the annealing process, the main difference between normalizing and annealing is that the cooling rate of normalizing is a little faster, so the production cycle of positive heat treatment is short. Therefore, when annealing and normalizing can meet the performance requirements of parts, normalizing shall be used as much as possible. Most medium and low carbon steel billets are usually treated with positive heat. General alloy billet material often adopts annealing, if normalizing, because the cooling rate is faster, make its normalizing higher hardness, is not conducive to cutting.
Q:How can the offset film affixed to the cold-rolled steel sheet be removed?
On the hard surface of the self-adhesive mark, we can use non greasy wash water on the surface of the object, and then gently wipe with soft cloth; with industrial alcohol or gasoline can also remove these traces. If these stickers are found on the skin, they can also be removed with lemon juice.
Q:What are the functions and classifications of galvanized sheet?
Construction industry: roof, roof components, balcony panels, window sills, kiosks, warehouses, rolling doors, heaters, rainwater pipes, etc.Household appliances: refrigerators, washing machines, switches, air conditioners, microwave ovens, toasters, copiers, vending machines, fans, vacuum cleaners, etc.Furniture industry: lampshade, wardrobe, table, bookshelf, counter, signboard, medical equipment, etc.
Q:What is the hardness of the wear-resistant steel plate?
The microhardness of the wear-resisting layer of the wear-resisting steel plate can reach HVl700 ~ 2000, and the surface hardness can reach HRc58 to 62. The wear-resistant layer of the wear-resistant steel plate is mainly made of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbides in the metallographic structure are distributed in a fibrous direction, and the direction of the fiber is perpendicular to the surface.
Q:The differences and uses of cold rolling and hot rolling
Cold rolled forming steel allows partial buckling of the cross section, thus taking full advantage of the post buckling capacity of the member, while the hot-rolled section does not allow partial buckling of the cross section.
Q:What are the rental costs for steel sheet piles?
The utility model has the advantages of high strength, easy to break into the hard soil layer; construction in deep water, if necessary with the inclined support into a cage. The utility model has the advantages of good waterproof performance, forming a cofferdam with various shapes according to requirements and repeated use for many times; therefore, the utility model has wide application.
Q:The difference between steel edge sealing strip and steel plate putty water stop belt
The good bonding between galvanized steel sheet and concrete makes the waterproof performance better. The utility model relates to a steel edge rubber water stop strip, which is characterized in that a water stopping product is adopted, which adopts a non equal thickness structure, a strong strength area and a waterproof zone, and makes the parts of the utility model be uniform and reasonable in force. The utility model relates to a steel edge rubber water stopping strip, which is additionally provided with an installation hole and is connected with the steel bar. The utility model has the advantages of firm fixation, easy displacement, and uniform and reasonable force for each part. When the utility model is in construction, the clamping surface of the clamping plate of the utility model is large and is not easy to be dislocated; the steel plate is additionally provided with an installation hole and is connected with the steel bar; the utility model has firm fixation and is not easy to displace. Good adhesion between galvanized steel sheet and concrete, and steel rubber stop makes waterproof better. A waterproof products produced by our factory in the buried steel edged waterstop is combined to galvanized steel and natural rubber raw material consisting of a rubber body material, it adopts the aging of natural rubber and excellent antioxidant performance, with strong self adhesive; high temperature in summer has no flow, low temperature in winter not the crisp; and has excellent water resistance, acid and alkali resistance and aging resistance; long service life, the product itself is non-toxic, the characteristics of a good environment.
Q:What's the effect of water stopping between steel plate and water stop strip? What's the difference between the process and the sealing process?
Water stopping principle: the water stop bar is expanded by water absorption and then squeezed with concrete to stop the void.Construction technology: the stop bar is square long strip, and parallel lap method is adopted when connecting. No break point can be left in the middle. Construction units in order to facilitate, often like to use the water bar, concrete pouring in the completion of the pressure on the wall concrete pouring surface, or reserved groove, two times mosaic.Good and bad analysis: simple construction, less investment, relatively economic. But there is no water stopping effect and the water stopping steel plate is good. There are many unforeseen problems during the construction process. One is that the reinforcing bars are not close enough to be laid. Two is the time is too long, moisture absorption expansion, the impact of the effect, especially in the rainy season, air humidity, rainfall, water retention is worse. Three construction joints are not smooth, poor contact. Usually, this method is not ideal for stopping water. For example, when the water stop bar is installed, the retaining of the groove is too large to be fixed effectively; the small inlay is not in place; when the concrete is poured, the utility model is easy to shift under the action of the concrete buoyancy.
