Technical data

Square Steel Billet Size Q235,Q255,Q275,Q345,3SP,5SP,20MnSi

Feature Steel Billet

Rectangular billet continuous casting billet and mainly general carbon steel, low carbon low silicon cold-rolled material, high quality carbon structural steel, high strength low alloy steel, special steel, etc. 

The billet is mainly divided into two kinds from the shape: 

Slab: cross section width and height of the ratio of the larger, mainly used for rolling plate. 


Billet: equal cross section width and height, or a huge difference, mainly used for rolling steel, wire rod. , 

Steel billets have distinct characteristics as compared with already furnished steel bars and products. Billets have a specific grain structure, which enables the metal to be processed more intricately. Steel billets are also known for their malleability and ductility, especially when exposed to varying temperatures during shaping and molding.

Usage-Billet Steel

 Used for the plant, the bridge,shipment building high-rise building construction,lifting and transportation machinery, equipment manufracturing base building the support foundation pile manufacturing.

Billets, or ingots (as they sometimes referred to), are not of practical use until they have been formed into more functional shapes and sizes. While they have already been put in the furnace, they still require a series of shaping and molding procedures such as hot and cold working, milling and cutting before they are sold in hardware stores, or used for different applications. The unformed billets, however, can be used in striking currency such as coins and as reserves, similar to gold bars.


FAQ-Billet Steel

We have organized several common questions for our clients,may help you sincerely:

Q:How are the billets classified?
According to the specifications are divided into: billets, billets, round billet, rectangular billet and slab. According to the steel grade: Q235, Q195, GCr15 and so on........................
Q:20 what is the difference between manganese silicon steel billet and Q235 billet?
In brief, the ingredients are different and the uses are different.20 manganese silicon steel billet for high strength steel,Q235 billet is almost the most common steel, requiring the lowest.
Q:Who knows the diamond is?Who knows the diamond is carbon? Is it C60?
It is also called the diamond diamond, crystal, it is not the molecules themselves, so the formula does not apply to.C said it is only by this kind of carbon elements. While C60 is footballene is another matter, the 60 is because it is a molecular crystal, each molecule consists of 60 carbon.
Q:Reasons and treatment methods of billet stripping in continuous casting
Uneven cooling causes stripping.Check that the water jacket is uneven;Then check the two cold, the nozzle is not even spray cooling water, jet angle position is correct.
Q:The form of carbon in carbon steels
In solid solution, it is in the interstitial space of lattice, resulting in lattice distortion. The solubility of carbon in gamma -Fe is maximal, but not more than 2.11%; the solubility of carbon in alpha -Fe is not more than 0.0218%; and in Delta 6-Fe, no more than 0.09%.
Q:I would like to ask what products need billet,
The main mold manufacturers, equipment manufacturers, military departments, measuring and cutting tools manufacturers.As for sales, one to information, two to high quality and low price, three to find relations.
Q:If the casting speed is not steady, what will happen to the billet?
First of all, the probability of slag circle, dimple, crack and blowhole on the surface of the billet will increase, and the slag inclusion in the slag will increase, which will affect the internal and surface quality of the slab.
Q:Difference between medium frequency continuous casting billet and electric furnace continuous casting billet
In general, the difference between medium frequency furnace steelmaking and electric arc furnace steelmaking:1, intermediate frequency furnace slag can not, so the harmful elements such as P, S and other elements can not be removed, and the electric arc furnace can;2, if not blowing furnace carbon reduction, so C elements cannot be adjusted downward, and the arc furnace can only increase;
Q:Carbon and low alloy steel billet has specific uses difference between them and what is the difference?
Primeton Pu board generally refers to A3; carbon steel refers to the high quality carbon steel, such as No. 45 steel, 35 steel and so on;
Q:The role of carbon content in steels
Therefore, the carbon content determines the use of steel: low carbon steel (carbon content < 0.25%), commonly used as extrusion and stamping materials; carbon steel (carbon content < 0.6%), commonly used as mechanical parts; high carbon steel (carbon content > 0.7%), commonly used tools, tool and mould etc..
