Advanced Chamfered Mold Design for Reducing Slab Corner Cracks in High-Speed Steel Casting

Hyoung-Jun Lee, Kyung-Chul Cho, Sang‐Hum Kwon, Seong-Yeon Kim et autres

Abstract Transverse corner cracks on the slab surface occur most frequently, particularly in hypo-peritectic steel cast by the vertical-bending casters. These defects require additional surface machining before rolling, along with compensating for temperature drops in the reheating furnace, which significantly increases steel …

Development of a Novel Method for Detecting Temperature and Heat Flux Distribution in Cu Mold During the Continuous Casting Process and Its Application to Analyzing Molten Steel Fluid Patterns Inside the Mold

Hyun‐Jin Cho, Seong-Yeon Kim, Hyoung-Jun Lee, Youn‐Bae Kang

Abstract Fiber optic sensor with Bragg Gratings (FBG) was employed as temperature sensors in continuous casting mold of molten steel. It is superior to conventional thermocouple that temperature profile along the direction of casting can be measured in more finely manner, depending …

Effect of Trace of Oxygen in Ar Gas on Initial Growth of Nozzle Clogging Deposits on SEN for Ti Added Ultra‐Low C Steel Casting

Joo-Hyeok Lee, Janghoon Kim, Myeong-Hun Kang, Seong-Yeon Kim et autres

The possibility of reoxidation of Ti‐ultra‐low C (Ti‐ULC) steel by a trace of oxygen in Ar gas, which is injected in a submerged entry nozzle (SEN), is investigated. A commercial‐grade unpurified Ar gas with P O2 = ≈10 −4 bar and a …

Analysis of Mold Level Hunching by Unsteady Bulging during Thin Slab Casting.

U-Sok Yoon, In-Wan Bang, J. Rhee, Seong-Yeon Kim et autres

In order to analyze the phenomenon of mold level hunching (MLH) during thin slab casting process, the variation of the mold level and the bulging of strand were measured and analyzed using Fast Fourier Transform (FFT) spectrum analysis. Both of mold level …
