 Steel Billet/Bloom Made by Continue Casting Blast Furnace


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


Steel Billet/Bloom Made by Continue Casting Blast 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  Steel Billet/Bloom Made by Continue Casting Blast Furnace


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


①How about your company

A world class manufacturer & supplier of castings forging in carbon steel and alloy steelis one of the large-scale professional investment casting production bases in China,consisting of both casting foundry forging and machining factory. Annually more than 8000 tons Precision casting and forging parts are exported to markets in Europe,America and Japan. OEM casting and forging service available according to customer’s requirements.


②How to guarantee the quality of the products

We have established the international advanced quality management systemevery link from raw material to final product we have strict quality testWe resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.


How do you determine the billet section size? Determination of billet section size in addition to considering the deformation of rolled piece to have enough quantity to meet the finished productThe quality requirements, but also should consider to roll strength and rolling bite into the limitations. The deformation size has a great influence on the product performance.Can make the metal internal organization and deformationPerformance can not meet the quality requirements.Such as high speed steel must have enough deformation,The carbide networkTo be broken or heavy rail and seamlessSteel pipeBy the total elongation coefficient of steel ingot to the finished product usually must alsoGuarantee up to50). However, in the roll diameter and reduction given conditions, if the blank section size is too big, not only canCan occur due to deformation of impervious surface deformation of rolled piece,But also roll breakage happens,biteEntering the rolled piece difficult, etc., generally billet height and roll diameter has the following relationship: The H/DOr less0.49                       (4 to 5) Type in theH.- height of billet,mm; D- work roll diameter,mm. type4 to 5The data is given from the guarantee roll blank section strength and bite conditions decisionThe size of the important parameters. Ingot after the blooming mill rolling into or through forging press forging into different specifications of the billet,Are all kinds of finished product rolling millThe main raw material.Cross section shape of the billet (as shown in figure4-3) there are square, rectangular and circularAnd other shapes (alien). There is a wide variety of billet section shape is the root cause of steel varieties, specifications range is very wide,Profile is varied,And with the same cross section shape of all varieties of steel billet production isNot possible.
