Continue Casting Steel Billet Made by Blasting Furnace
1.Structure of Continue Casting Steel Billet Made by Blasting Furnace
Continue Casting Steel Bloom 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 Continue Casting Steel Billet Made by Blasting Furnace
Continue Casting Steel Bloom 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.

5.FAQ of Continue Casting Steel Billet Made by Blasting Furnace
We have organized several common questions for our clients,may help you sincerely:
①How to make diffirence of the grades?
You can do the chemical composition of the products by some lab.for example send the samples to SGS inspeciting company.
②If we want to get the shortest production term, which spec. is more easy to produce?
150*150*12000MM, Q235.
③Which steel mill is the best quality?
In China, if the national steel mill's quality is very good and stable, or private steel mill, you have to make sure the furnace is blast furnace and the quantity every day is big enough.
