Steel Strips Based On The Galvanized Steels

 

1.Structure of  Steel Strips Based On The Galvanized Steels

 

 Steel Strips Based On The Galvanized Steels is  one  kinds  of  building  material  on  construction. Steel  sheet  in  melting  zinc trough, the sticking of a layer of zinc sheet. At present mainly adopts continuous galvanizing process, namely the continuous roll of steel plate in the melt zinc plating tank made of galvanized steel sheet; Alloying of galvanized steel. This kind of steel plate is made by hot dip method, but after the slot, immediately heated to a temperature of about 500 ℃, it make the generation of zinc and iron alloy membrane. This kind of galvanized volumes with good coating of the sex and weldability.

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:What's the meaning of "double light" in strip cold rolling?
Double light: This is generally cold rolled roll of the statement, cold-rolled grades SPCC, SPCC is generally a general term, including SPCC-SB, SPCC-SDSPCC-SD is a single light, it is now generally rough surface is the material directly labeled SPCC, remove the suffixSPCC-SB is double light, the surface is mirror surface, also called bright surface
Q:What are the high speed steel strips and material specifications?
(1) main usesUsed for stamping machine parts, metal products and manufacturing structural parts, etc..(2) the grade and chemical composition of the materialIn line with GB699 (high-quality carbon structural steel technical conditions), the brand is 15-70# steel provisions.
Q:What is cold rolled strip and hot rolled strip? Why is it called strip steel?
The only so called strip is because this kind of material is shaped, say vulgar point like our waist belt like si,
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:Pickling process of cold rolled strip
The pickling section can be divided into two ways: sulfuric acid pickling and hydrochloric acid pickling, but because hydrochloric acid pickling has more advantages, we can explain it by the acid washing mechanism of hydrochloric acid.The chemical reaction between hydrochloric acid solution and iron oxide scale is:FeO + 2HCl = FeCl2 + H2OFe2O3 + 6HCl = 2FeCl3 + 3H2OHydrochloric acid solution can quickly dissolve all kinds of oxide scales, pickling reaction can be carried out from the outer layer. Hydrochloric acid pickling is mainly chemical corrosion, and hydrochloric acid pickling is very harmful to metal matrix. Therefore,The structure is not sensitive to the efficiency of acid pickling of iron oxide scales, and the steel surface after pickling clean silver. The rate of acid washing reaction is closely related to the degree of cracking of strip iron before picklingOff.
Q:What is strip steel?
A steel strip, also called a strip, is actually a thin, narrow and long steel plate, usually rolled.
Q:What is the difference between galvanized steel cold base galvanized steel strip and hot galvanized steel strip?
The soaking process is mainly used in electroplating process, some appearance of repairing damaged more, a large number of plates or on the hot dip galvanizing process implementation. Cold is the use of zinc plating on the surface of the steel plate with filler replacement attached to a layer of zinc to the surface of the steel plate, the plating thickness is very small, generally between 10-50g/ square meters, anti-corrosion performance is poor, and its effect and general coating, sometimes as coated with a layer of anti rust oil in key parts this method should not be used so as not to affect the structure and properties of corrosion. The above is hot dip galvanized plate is heated to 500 DEG C into liquid zinc (zinc liquid temperature about 470 degrees Celsius), the formation of Zn Fe alloy coating and zinc layer, this method is the most commonly used, and the thickness of zinc can be controlled in more than 20 mu, ranging from 60g-275g/ square meters, even more thick, far better than cold plating process.
Q:What are the characteristics of cold rolled strip technology?
Pickling process: remove the oxide film on the surface of the raw material to ensure the high quality of the material;Rolling process: the raw material is rolled into the thickness required by the customer with a high precision mill;Bell type bright annealing: the material which is hardened by rolling can be restored to normal flexibility;Fine leveling: the softened material is refined into flat and easy to process finished material;Finished product: the finished product is packed with fine finish;Flat, strip: according to different requirements of customers, finished products straight, strip.
Q:Hot rolled strip and hot rolled strip are also sealing plates? What's their function?
First of all, there are some hot rolled strip, the main role is to prevent roll cooling water flow to the workpiece, affecting the crown of the strip and shape control.
