Continue Casting Steel Bloom by Blast Furnace Q235
1.Structure of Continue Casting Steel Bloom by Blast Furnace Q235
Continue Casting Steel Bloom by Blast Furnace Q235 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 Bloom by Blast Furnace Q235
Continue Casting Steel Bloom by Blast Furnace Q235section 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.

4. Continue Casting Steel Bloom by Blast Furnace Q235 Specification
Continue Casting Steel Bloom by Blast Furnace rolled steel, after processing can be used for mechanical parts, forging parts, processing all kinds of steel, steel Q345B channel steel, wire rod is the role of the billet. Steel billet is used in the production of semi-finished products, generally cannot be used directly for the society. Steel billets and steel are strictly divided into standard, cannot decide to whether the business enterprise of the final product, and according to unified standards to perform the whole society. Typically, billet and the steel is relatively easy to distinguish, but for some steel billet, and have the same specification and same steel purposes (such as rolling tube billet), whether can be used for other industries, whether through steel processing process, whether through a finished product rolling mill processing to distinguish

5.FAQ of Continue Casting Steel Bloom by Blast Furnace Q235
We have organized several common questions for our clients，may help you sincerely：
①How to make the contract for the long term business?
Because the steel billet price is changing according to the market price changing every day, so we could't make a long term business contract with our customer.
②How to guarantee the quality of the products？
We have established the international advanced quality management system，every link from raw material to final product we have strict quality test；We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.
And you can employ the third party inspecting company to check and get the report from them dirrectly or you can pay and then we can arrange for you before loading.And if you have any feedback about the quality you can tell us in the first time.
③Except the Q235, are there any other grades we can order?
Yes, there are, you can choose and then we do that for you, for example Q195/215/275 or you can give us the chemical composition and then we make for you.
