Slab Continuous Casting

Effects of Crystallization of Mould Fluxes on Property of Liquid Slag Film and Its Impacts on Peritectic Steel Slab Continuous Casting... 

Three typical mould fluxes for peritectic steel slab continuous casting with different basicity used in commercial production were chosen and then prepared with chemical pure agents. CaO, Na20, MnO and Li20 were added as carbonates. The specific compositions were listed in Tabic I.

Although more and more zinc sheet and strip are produced in continuous mills, some is stiU produced by rolling slabs cast in open or closed book-type molds made of cast iron (124—127). The casting temperatures are between 440 and 510°C, mold temperatures between 80 and 120°C. The contact surfaces of the mold must be smooth and clean to allow unrestricted shrinkage of the cast slab. Mold lubricant is not necessary, but if used should be held to a minimum. Slabs cast in open molds must be skimmed immediately to remove surface oxide. Rolling slabs are cast 1.87—10 cm thick. 

Alumina—graphite refractories, almost all continuous casting ware, have come into much greater use as continuous casting has spread in steelmaking. These refractories are used in shrouds that conduct the molten metal from the ladle to the tundish, in the subentry tubes that take the metal from the tundish to the mold, in isostatically pressed stopper rods, and in shroud tubes for slab and bloom casters. The alumina—graphite compositions are used in these products because of the thermal-shock resistance and corrosion resistance they impart to the product.

In a continuous casting machine, molten steel is poured into a reservoir at the top of the machine. It passes at a controlled rate into a water cooled mold where the outer shell of the steel becomes solidified. The steel is drawn down into a series of rolls and water sprays, which ensure that it is both rolled into shape and fully solidified at the same time. At the end of the machine, it is straightened and cut to the required length. Fully formed slabs, blooms, and billets emerge from the end of this continuous process. 

Continuous Casting. Ihis process, wherein liquid steel is poured directly into seniitinished shapes, such as slabs, blooms, blanks, or billets. 

Steel sheets, widely used in thousands of products, are produced Irorn slabs from a slabbing mill, continuous casting machine, or pressure-poured molils. These pieces are hot-rolled in a hoi strip mill, descaled bv pickling in an acid solution, and then cold-rolled and tempered m a cold-reduction and temper mill. Tlte cold-tolled snip may he marketed in coil form, or carried to a side-trimming and sheet shearing line, where it is customized lor speeilie user needs. 

Austenitic steels are produced as castings, ingots of all sizes and as continuously cast billets and slabs. The other types of stainless and heat resistant materials mentioned in table 4.1 are cast predominantly as ingots of a moderate size, although martensitic and ferritic-austenitic steels are also commonly used as castings.
