Q:How to drill through galvanized steel strip quality piercing eye
To distinguish the quality of galvanized strip is mainly from the aspects of surface finish / coating thickness / coating thickness difference / coating adhesion / salt fog test time and so on. GB 4175.2-1984 armored cables, galvanized steel strip, /GB-T 15392-1994, width less than 700mm, continuous hot-dip galvanized steel strip, etc., as you requested.
Q:What are the differences between strip steel and round steel? Where are they mainly used?
Round steel is a solid strip of steel whose cross section is round. The specifications are expressed in millimeters of diameter, such as "50", which means a round bar of 50 millimeters in diameter. Round bar is divided into three parts: hot rolling, forging and cold drawing. Standard Specification for hot rolled round steel is 5.5-250 mm. Of which: 5.5-25 mm small round bars are mostly supplied by straight strips. They are used as reinforcing bars, bolts and various mechanical parts. Round bars larger than 25 millimeters are used mainly for making mechanical parts or for seamless steel tubes.Mainly used in the manufacture of various tools, cutting tools, moulds and tools (see tool steel), but also a large number of used in the manufacture of various mechanical parts.
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:The relation between hot rolled strip and cold rolled coil, hot rolled strip and cold rolled strip
Hot rolled strip: hot rolled strip, also known as hot rolled strip, commonly known as hot plate. Hot rolled strip with width less than or equal to 600mm, steel plate of thickness 0.35-200mm and steel strip of 1.2-25mm thickness. The strength of hot rolled steel plate surface quality is relatively low, almost (oxidation low smoothness), but good plasticity, general plate, cold-rolled plate, high strength, high hardness, high surface smoothness, generally can be used as a punching sheet, plate.Cold rolled strip: cold rolled strip and sheet, general thickness of 0.1 ~ 3mm, width of 100 ~ 2000mm, all with hot rolled strip or steel plate as raw material, at room temperature by cold rolling rolling
Q:Reasons for black side of hot strip galvanizing
Luoyang Taihong hot galvanizing factory to tell you the reason, the emergence of the black side of reason is generally divided into: contains too much iron impurities of galvanized steel strip into the liquid, thus causing blackening; resulting in the high current hot galvanized steel blackening;
Q:Is the strip steel strip?
The steel can be divided into sheet, strip, wire, profiles, tubes and other categories, collectively refers to the strip steel sheet and strip, it only refers to the shape and thickness, classification, processing methods (hot rolled) is Never mind, the difference is that the material delivery requirement is size length * width * thickness. The strip, the strip is measured for delivery size thickness * width * L (where L is not required to provide, usually coiled strip) delivery.
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's the cutting edge of cold rolling strip?
Do you mean the cutting edge is the indication of the steel roll out of the factory? When the steel factory leaves the factory, the steel coil will have the burr and the cutting edge two kinds, the rough edge is the steel strip two, the edge is not neat. The trimming is the two sides of the steel band, and the width of the strip is certain when it is trimmed.
Q:What is the difference between strip steel and silicon steel?
Silicon steel is a silicon iron alloy with silicon content of about 3%~5% and other major iron. Divided into oriented silicon steel and non oriented silicon steel, it is an important soft magnetic alloy in electric power, electronics and military industry. Silicon steel refers to a low carbon silicon iron alloy with silicon content ranging from 0.5% to 4.5%. It is divided into non oriented silicon steel and oriented silicon steel because of its different structures and uses. Silicon steel is mainly used as the core of various motors, generators, compressors, motors and transformers. It is an indispensable raw material for electric power, household appliances and other industries.
Q:Pickling process of cold rolled strip
In addition to the task of removing the iron oxide scale on the strip surface, the continuous pickling line still has several functions:(1) trim the side of the strip with a disc shear.(2) regulating the quality of rolled steel, according to the production requirements of large volume of hot-rolled steel will be divided into small volumes, or several small steel coils merging into a large, in order to improve the production of cold rolling mill.(3) check and eliminate the harmful surface defects of strip steel after each process.(4) apply a layer of oil on the surface of the pickled steel strip, which can prevent rust and lubricate.
