Alloyed Steel Billets and Blooms Manufactured by Continue Casting
1.Structure of Alloyed Steel Billets and Blooms Manufactured by Continue Casting
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 Alloyed Steel Billets and Blooms Manufactured by Continue Casting
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.

4. Alloyed Steel Billets and Blooms Manufactured by Continue Casting Specification
Steel Billets Manufactured by Continue Casting 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 Alloyed Steel Billets and Blooms Manufactured by Continue Casting
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.
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.
Inclusions with the steel flow to lower part of crystallizer, the faster the speed, the deeper the impact.Because of proportion, inclusions have a rise trend.Movement is a steel circular trajectory, and buoyancy (vertical direction) on the synthesis, the impurities to slab inner arc lateral movement, to the solidification front, was captured by thick area.This quality problem, both in billet, round billet, slab casting machine of arc, exist, have to take a variety of methods, such as machine and electromagnetic stirring in the arc, and electromagnetic brake to solve on the slab.Japan's kawasaki steel mills and the Japanese steel pipe water island fushan factory or even change the arc slab casting machine to bend type casting machine, make the period of more than 3 m of vertical section, to facilitate inclusion floatation, for most curved round billet casting machine, a good performance of mold electromagnetic stirring is a must.Rotating force produced by electromagnetic stirring, make the liquid steel in the process of downward, strong circular motion, this kind of games (major) than the steel liquid to produce centrifugal force, the shell compression, while the mixed proportion (light) centripetal movement, gathered together, high temperature of the mixed collection will make particles increases and tends to rise more, avoid the inward arc movement.And the function of electromagnetic rotation force, reduce the liquid steel flow injection impact depth, and conducive to inclusion floatation.
29.According to the influence of finished product processing performance points, inclusion what type? According to the inclusion, plastic deformation can be divided into brittle inclusions inclusions and half plastic inclusions. Brittle inclusions generally refers to those who do not have plastic deformation capacity, complex and simple oxide composite oxides, nitride and notThe deformation of the ball,Dot inclusions.Because the wire is approved by billet hot rolled into wire rod after the drawing and form,For the deformation is large,soA1203And spinel deformation brittle inclusions is very big to the harm of wire rod. Inclusions in steel processing through plastic deformation when have good plasticity, extends along the flow direction of steel slits, belong to itClass hasThe SiO2Low content of iron silicate, iron sulfide, manganese(Fe,Mn) SAnd so on. Half of the plastic inclusions generally refers to all kinds of compound aluminum silicate inclusions. Deformation behavior of non-metallic inclusions in steel is more complex, not only depend on the type of inclusions, and composition and inclusionClosely related to deformation temperature.
③What is the advantage of the continue Casting steel billet comparing to the die casting steel billet?And how is the process?
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.
