Abstract
The heat transfer coefficient (HTC) is an essential parameter in the numerical simulation of solidification during the secondary cooling zone in continuous casting. Accurate prediction of the HTC is essential for controlled slab cooling and ensuring product quality by preventing crack formation. The HTC is commonly estimated using empirical equations from literature. However,...
Accurate prediction of the temperature distribution in continuously cast steel slabs is critical for maintaining product quality and mitigating defects such as cracks and segregation. Mathematical modeling serves as a fundamental tool for investigation of the dynamics of temperature and solidification front evolution during the process.
A two-dimensional computational model is presented for...
During the cooling process on the cooling bed of alloy cold heading steel billet, the quality defect of billet bending exceeding the standard often occurs. In the present work, the reason for its bending is analyzed from the perspective of heat dissipation and phase transition during the cooling process of billet. It is shown that the main reason for the bending of alloy cold heading steel is...
The design of billet moulds fulfills multiple, conflicting, objectives. High productivity at minimal cost remains the primary goal of steelmakers, requiring elevated casting speeds while ensuring optimal surface quality.
The copper mould plays a critical role in the continuous casting process, with its design centered around three key parameters: mould taper, cooling system efficiency, and...
The accurate knowledge of the cooling heat-flux in continuous casting spray cooling is essential to exactly control the cooling conditions. Recent investigations on laboratory test rigs by other research groups showed that the cooling heat-flux depends on many parameters and can not sufficiently be described by simple relations between spray water/air density and heat-flux density. In addition...
