Steel Bloom/Billet Manufactured by Blast Furnace by Continue Casting Making
1.Structure of Steel Bloom/Billet Manufactured by Blast Furnace by Continue Casting Making
Steel Billets Manufactured by Continue Casting 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 Steel Bloom/Billet Manufactured by Blast Furnace by Continue Casting Making.
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 Steel Bloom/Billet Manufactured by Blast Furnace by Continue Casting Making
We have organized several common questions for our clients，may help you sincerely：
①How about your company？
A world class manufacturer & supplier of castings forging in carbon steel and alloy steel，is 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.
②Inclusions in the continuous casting billet come from? Found in the continuous casting billet of inclusion complex, forms.Judging from the inclusion of ingredients, can be roughly know the source of inclusions. (1) the weak deoxidizing elements contained in the inclusion is more, and SiO2 + MnO content greater than 60%, the size is more than 50 microns, which can determine the inclusions are caused by air and molten steel secondary oxidation; (2) inclusion composition and refractory materials, with special shape, size is larger, can determine for refractory erosion;(3) inclusion contains such elements as potassium, sodium, is due to mould protection slag in molten steel.
③What is the advantage of the continue Casting steel billet comparing to the die casting steel billet?
Compared with die casting, continuous casting has the advantages of: 1. To simplify the Steel billet The production process 2. Improve the metal yield 3. Improve the quality of the billet 4. Reduces the steel worker's labor intensity 5. Save energy and reduce consumption
Steel billet is produced by the method of through three processes: It is through the steelmaking system of continuous casting equipment, directly by the molten steel pouring into billet; The second is the steelmaking system in the production of steel ingot casting billet through system of steel rolling rolling equipment or processing of steel semi-finished products; Three is the steelmaking system production of steel ingot by forging the semi-finished product processing equipment.
