Continuous Casting of Steel
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, mathema...
متن کاملNumerical and Physical Modelling of Steel Flow in a One-strand Continuous Casting Tundish
Constantly increasing customers demands for the production of high and very high-quality steels, promote the intensive technological development of their production. Since the dominating method of global steel production is continuous casting, the tundish has become very important metallurgical unit. Nowadays, tundish is not only a storage vessel which guaranty the continuous casting of steel, ...
متن کاملInvestigation of Fluid Flow and Steel Cleanliness in the Continuous Casting Strand
Fluid flow in the mold region of the continuous slab caster at Panzhihua Steel is investigated with 0.6-scale water model experiments, industrial measurements, and numerical simulations. In the water model, multiphase fluid flow in the submerged entry nozzle (SEN) and the mold with gas injection is investigated. Top surface level fluctuations, pressure at the jet impingement point, and the flow...
متن کاملMathematical Simulation for the Effects of Flow Control Devices in a Six- strand Tundish in Continuous Casting of Steel Billet
The method of continuous casting of steel is now often used in the metallurgical industry, due to the increasing demand for the production of high – quality steel. An important device of continuous casting machine is the tundish, in which a stabilized steel flow has a crucial effect on the quality and efficiency conditions of the continuous casting process. In this study fluid flows in a six – ...
متن کاملControl issues in continuous casting of steel
Continuous casting plants are highly complex plants whose performance requires reliable mold level control system. Several effects greatly influence the surface quality of the final product and if these are not suppressed sufficiently by the mold level control system, than the production speed, hence the productivity has to be lowered. This paper analyses the most important disturbance and thei...
