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.

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

We have organized several common questions for our clients，may 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.
