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:Is the coil strip? Is hot rolled coil and hot rolled strip the same?
We found differences between strip and hot rolled strip width is below 1000mm, so it can be distinguished by the Ruifeng strip and Wuhan specifications eye coil, as to why some people use a strip coil, it depends on their factory mill can tie what width, this demand is also different.
Q:What is the hardness of cold rolled steel strip?
The thickness of cold rolled strip and sheet is 0.1 ~ 3mm, and the width is from 100 to 2000mm. The products are made of hot rolled strip or steel plate and rolled in cold rolling mill at room temperature.
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: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 gas does the shear of the strip weld require for the welder?
Welding equipment includes welding machine and welding auxiliary mechanical equipment. According to the way of welding, it can be divided into two kinds of flash welding and welding.
Q:The relation between hot rolled strip and cold rolled coil, hot rolled strip and cold rolled strip
Cold rolled coil (annealed): hot rolled coil obtained by pickling, cold rolling, batch annealing, flattening, and finishingThat is, the biggest difference between hot rolled coil and cold rolled coil is that the heat treatment process is different. (annealing process)Compared to the specific heat roll, the cold-rolled roll has a bright surface and a high degree of finish, but it produces more internal stress and is often annealed after cold rolling.
Q:What is the difference between steel strip and strip steel?
The steel strip is the product which the processing enterprise cuts the strip steel according to the specific machine size to cut into a certain length, the width, generally assumes the enclosed circle shape. For example, steel conveyor belts, such as furniture or wood processing enterprises, "band saw" saw blade, but also steel band.
Q:What is the difference between cold plate and strip steel?
Strip steel is a kind of narrow and long steel plate produced by various rolling mills to meet the needs of industrial production of various metal or mechanical products in different industrial sectors. Strip steel, also known as steel strip, is within 1300mm in width, and the length varies slightly according to the size of each roll.
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:1 can thick galvanized steel square pipe burn welding?
Better not to use electric welding, it is easy to burn through, even if burned well, deformation is very serious.
