Product Description:

1. Product Description

Narrow strip steel is below 650 mm steel, the product in a bar or roll supplies.Due to the edges of the strip shape after rolling strip steel is more suitable for welding after the slitting, so much for welded pipe, metal construction and daily necessities such as blank.With method of continuous production of narrow strip steel by using many sets of vertical roll mill and obtain good shape of edge, the edge shearing defects such as flash and burr, thus ensuring welding performance.It than with wide strip slitting machine cut into strip saves a vast amount of equipment, so it is more suitable for simple equipment of small and medium-sized enterprises.

 

 

 

2. Main Features 

 

Hot rolled narrow strip in the old open-train mill in the production process of flat steel production process is similar in general section mill;In the new continuous mill production, its technological process and equipment structure form basically similar with wide strip production technology for HSM.Hot rolled narrow strip steel billet for slab and billet used in the production of two.From increasing production capacity and simplify the production process, the slab is good, but must be sufficiently workshop or add big mill to provide.When using billet as blank, although production was lower, but the source is more easily, for small and medium-sized enterprises, have simplified equipment and the advantages of independent production.The main factors influencing the quality of hot rolled narrow strip steel product with billet defects, rolling temperature, rolling tension and roll wear and surface roughness, etc

4. Application

The classification of strip steel by the material divided into two categories, ordinary steel strip and high quality steel strip;According to the processing method is divided into hot and cold rolling.The purpose of strip steel is widely used in production of welded steel pipe, cold bending steel billet, manufacturing bicycle frame and wheels

Q:What's the difference between cold rolled strip and cold rolled strip?
Cold rolled steel sheets are made from hot rolled sheets at normal temperatures. Although they are rolled during processing, they can also cause steel plates to heat up. Nevertheless, it is called cold rolling. Because of the cold rolling of continuous hot rolling, the mechanical properties are poor and the hardness is too high. It must be annealed to restore its mechanical properties. Rolled rolls are generally used to make products without bending or stretching.
Q:Steel industry, strip 195, where can strip be used?
Q195 carbon content is low, the strength is not high, plasticity, toughness, processing and welding performance is better.
Q:Why is strip heat cheap?
Coil is 800mm in width, material better than the strip, because hot rolled production to refining furnace.
Q:What are the differences between strip steel and round steel? Where are they mainly used?
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. The strip is supplied in general, and has the advantages of high dimensional accuracy, good surface quality, easy processing and material saving. 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.
Q:What does galvanized steel strip A6 mean?
Galvanized steel strips are cold-rolled or hot-rolled, long and narrow strip steel plates coated with different layers of material called zinc. Hot galvanizing has the advantages of uniform coating, strong adhesion, long service life 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 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 about the strip scraping in the annealing furnace?
Thus forming an air knife scratch. This kind of defect causes the product to be wasted because the coating is scratched. Proper control of strip tension in productionForce and adjust the nozzle distance, can avoid this kind of defect happen.
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.
