Surface velocity of the molten steel is critical to final product quality during the continuous casting of steel. Plant experiments using two different new sensors, Sub-meniscus Velocity Control (SVC) devices and nail dipping, are performed to evaluate their performance, and to quantify liquid steel velocities at locations 50 mm apart on the surface of(More)
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(More)
The present experiment was conducted to determine the digestible energy (DE), metabolizable energy (ME) content, and the apparent total tract digestibility (ATTD) of energy in growing pigs fed diets containing one of ten cottonseed meals (CSM) collected from different provinces of China and to develop in vitro prediction equations for DE and ME content from(More)
The aim of this study was to investigate the effects of graded levels of montmorillonite, a constituent of clay, on performance, hematological parameters and bone mineralization in weaned pigs. One hundred and twenty, 35-d-old crossbred pigs (Duroc×Large White×Landrace, 10.50±1.20 kg) were used in a 28-d experiment and fed either an unsupplemented(More)
Many quality problems in continuous-cast steel are related to mold level fluctuations, stickers, deep oscillation marks, and other events at the meniscus. These phenomena may be detected by monitoring temperature signals in the wall of the copper mold. This work applies computational models of transient heat conduction to investigate the potential(More)
