A schematic of part of the continuous casting process is depicted in figure 1, showing the tundish, tundish nozzle and mold regions. In a typical slab casting operation, the liquid steel flows from the tundish, through the ceramic tundish nozzle, and exits through bifurcated ports into the liquid pool in the mold.

Continuous casting is used to solidify most of the 750 million tons of steel produced in the world every year. Like most commercial processes, continuous casting involves many complex interacting phenomena. Most previous advances have been based on empirical knowledge gained from experimentation with the process. To further optimize the design and improve the continuous casting process.

Unlike other processes of casting, the time line of steps in continuous casting is entirely different. While in other casting processes, each step of casting heating of the metal, poring of the molten liquid into casts, solidification and cast removal are a sequential process, in continuous casting all steps occur congruently and hence it saves a lot of processing time.
The chemical composition, morphology, thermal stability, barrier and mechanical properties (traction and puncture), and functional groups were investigated. Overall, scg showed sound dispersibility and good interaction with the polymer matrix.

The continuous development of mould powder since its first introduction has now made continuous casting of many varied sections of steel as routine. Today, many types of mould powders with different compositions and shapes (granular, powder form, and extruded powders) are produced to suit the casting of diverse steel grades and sizes.
Segregation in cast products 9 and km is mass transfer coefficient. For slow solidification and/or vigorous stirring, k eff ≈ k e (scheil’s equation).
Continuous casting is the important linking process between steelmaking and rolling. As early as 1856, henry bessemer suggested a continuous casting method but just during the 1930s and 1940s continuous casting became a common production method for nonferrous metals and later from the 1960s for steels.

During the last decades, the continuous casting process has made steel grades with a chemical composition similar to peritectic steel are in this case molar volume (v) and molecular weight (m) of the mould powder.
Selecting the proper casting speed in continuous cast-ing is critically important for the productivity of a caster and the quality it produces. Many factors and require-ments have to be considered when choosing the right casting speed: superheat, steel-grade requirements, quality, safety, machine limits, and other production aspects.

The methods include vertical continuous casting and horizontal continuous casting. The article discusses the upcasting methods used in vertical continuous casting and strip casting used in horizontal continuous casting. The upcasting methods include outokumpu upcasting method, rautomead upwards vertical casting, and pressure upcasting.
Continuous casting is a mature, sophisticated technological process, used to produce most of the world's steel, so is worthy of fundamentally‐based computational modeling.
The scheduling of steelmaking continuous-casting (scc) processes is of major importance in iron and steel operations, since it is often a bottleneck in iron and steel production. Optimal scheduling of scc processes can increase profit, minimize production cost, reduce material and energy consumption, and improve customer satisfaction.
During the continuous casting of advanced high-strength steel slabs, both surface and internal discontinuities are prone to occur. These discontinuities can include cracks, voids, coarse nonmetallic inclusions, and heavy local chemical and microstructural segregation.
Physical properties of both steels and mould slags are needed as input data for the mathematical modelling of the continuous casting process. Routines for calculating the properties of mould slags and for estimating steel properties have been developed and are described in parts 1 and 2, respectively.
Continuous casting manufacture is different from other metal casting processes, particularly in the timing of the process. In other casting operations, the different steps to the process such as the ladling of metal, pouring, solidification, and casting removal all take place one at a time in a sequential order.

Reported data and own experimental results are used to formulate a cracking mechanism concept and to analyze the effect of the chemical composition of a metal on cracking in slabs during continuous casting of a low-carbon steel microalloyed with carbonitride-forming elements.
During the late twenties, siegfried junghans wished to produce cast rods and pipes in order to widen the basis of his brass-stock business. He soon found that the continuous-casting process, as described in the literature, particularly in patents, could never be used on an industrial scale with any chance of success, even though modifications were introduced.

Continuous casting, also called strand casting, is the process whereby molten metal is solidified into a semifinished billet, bloom, or slab for subsequent rolling in the finishing mills. Prior to the introduction of continuous casting in the 1950s, steel was poured into stationary molds to form ingots.
