Product Description:

 Alloyed Steel Billet/Bloom by Continue Casting Blast Furnace

 

1.Structure of  Alloyed Steel Billet/Bloom by Continue Casting Blast Furnace

 

Continue Casting Steel Billet Manufactured By Blasting Furnace is the raw material of all kinds of steel mill. Billet section of square, round, flat, rectangular and abnormity, etc Several, mainly related to shape of rolled products. Simple rolled section steel, choose cross section of square billet or rectangular billet. rolling The sector products such as flat steel, Angle steel, select the rectangular billet or slab. Had better profiled billet when production beams, channels, and in rolling process Lines and improve the yield. The raw material of round billet is the production of seamless tube. 


2.Main Features of  Alloyed Steel Billet/Bloom by Continue Casting Blast Furnace.

Continue Casting Steel Billet Manufactured By Blasting Furnace section size should meet the requirements of rolling deformation and finished product quality, but also roll strength and biting condition of restrictions. General steel Billet section height H. And the roll diameter D The ratio of the ( namely H/D) Should be less than or equal to zero 0.5 . Length of steel billet by finishing temperature, Rolling time and the length of the product Or times ruler. When heated too long accident prone to bump the furnace wall of steel, too short, furnace bottom utilization rate is not high, influence the heating furnace production. For the production Choose a variety of steel and steel billet, should consider the affinities of billet, as far as possible in order to improve the productivity of the roughing mill, simplify the stock management of workshop.

      There are three shapes of the steel billets: square billet, slab, rectangular billet The Chinese billet, rectangular billet is mainly suitable for rolling hot rolled strip, building reinforced bar, Ordinary wire, high speed wire rod and various small profile. Of the slab are mainly used for rolling plate and hot coil sheet.

5.FAQ of  Alloyed Steel Billet/Bloom by Continue Casting Blast Furnace

 

We have organized several common questions for our clientsmay help you sincerely 

 

①What kinds of the steel billet you have?

We usually export the Q195/215/235/275, size: 120*120/130*130/150*150*12000/6000mm steel billet to our customers..

 

②Could we get the third party quality inspecting report?

Sure, but the inspecting fee belong to our customers payment in advanced.

 

③What quality problem we could claim?

Any problem not meet the contract you can tell us and we will be respansible for you.

For example:The defect of billet according to its source can be divided into two categories:Lack of steelmaking and castingAnd the rolling defects caused by.From the defect of the parts and can be divided into two kinds of surface defects and internal defects.The main steel billet defectsThere should be: scar, crack, cracking and inclusions(See the non-metallic inclusions), shrinkage residual(See the shrinkage cavity), airbag, air bubble, insideCrack, burnt, internal heat, tail hole, teeth marks, folding, scratches, indentation, sag, Angle, bending(See the bending),Handle defects, torsion, crack, shear, mesh, cleaning up bad, skull patch, seam crack, split, out-of-tolerance and sizePitting, etc.

1)Airbags.Boiling steel billet shearing area appear similar to the defects of shrinkage cavity.Section on the vertical axis of symmetry of the tongueWave, wave gap in granular inclusions, blaze, discoloration, etc.Sometimes the surface of the bulge, tearing, shearing widthSuch as large surface phenomenon, finished product billet surface convex hull, cross section on the tongue shape wave, serious billet through a long hole.

Q:What is the HS number for billet export?
It's too broad. What kind of material (contains all kinds of metal components in order to confirm HS coding)?
Q:Does anyone know how much it costs to refine a ton of steel? What are the expenses involved?
Electricity, water, wages, raw materials, raw materials loss, charges, oxygen, according to their own circumstances, as well as freight and other expenses, now the steel profits are not as good as before, a ton of net profit is about 100 yuan
Q:How do steel billets come out?
Three, steel rolling:Rolling steel or continuous casting billet into various steels by rolling mill
Q:The role of carbon content in steels
Carbon is the main alloying element of iron and steel, so steel is also called iron carbon alloy. The main role of carbon in steel is to:1., the formation of solid solution tissue, improve the strength of steel, such as ferrite and austenitic structure, are dissolved in carbon;
Q:What is the difference between carbon three plants and carbon four plants?
Also known as C4 plants. Such as corn, sugar cane, sorghum, amaranth and so on.CO2 is the first product of the assimilation of photosynthetic carbon cycle in three carbon compounds 3- phosphoglycerate plants, known as carbon three plants (C3 plants), such as wheat, soybeans, cotton, tobacco, etc.. C3 plants have higher CO2 compensation points than C4 plants, so the survival rate of C3 plants is lower than that of C4 plants when the CO2 content is low.By contrast, the division of C3 plant cells is less definite than that of C4 plants, and CO2 uses less efficiently. To some extent, C3 plants may be considered as prokaryotes in plants, whereas C4 plants are more like eukaryotes".
Q:What are the causes of internal cracks in continuous casting billet?
A French Research Institute of carbon, sulfur and phosphorus influence on continuous casting billet hot cracking, a total of three test groups of carbon manganese steel, carbon, sulfur and phosphorus content of each sample is different.
Q:Charcoal is how to
Usually we measure the quality of charcoal mainly from the moisture content, volatile content, ash content, fixed carbon content and calorific value of charcoalTake it, thanks!!
Q:What is Alfa carbon? What is beta carbon?
Alfa is directly connected with the functional groups of carbon atoms of carbon atoms, such as CH3CH2COOH CH2 in which methylene propionate is Alfa carbon carbon carbon atom is the beta carbon atom is directly connected with the functional groups and the connection of the carbon (around Kazakhstan), such as the CH3CH2COOH CH3 propionic acid methyl carbon is the beta carbon
Q:What is the difference between steel and billet in the process?
My understanding is that..:Billet: Billet, refers to the casting of roughSquare steel: Square, Bar, the product is rolled on the basis of square billet.
Q:The reason for the blowhole in the billet to be pulled out by the continuous casting machine is 100
1: new furnace, new furnace lining contains more gas2: raw material no clean, no coincidence?3: melt protection? Temperature is not high, no refining and static?4:3 point, mold and traction to look for defects, mold cooling effect - water temperature - traction line and horizontal - traction process5: stop and pull
