Determination of the liquid steel viscosity curves using a high temperature rheometer

High Resolution Temperature Measurement of Liquid Stainless Steel Using Hyperspectral Imaging

A contactless temperature measurement system is presented based on a hyperspectral line camera that captures the spectra in the visible and near infrared (VNIR) region of a large set of closely spaced points. The measured spectra are used in a nonlinear least squares optimization routine to calculate a one-dimensional temperature profile with high spatial resolution. Measurements of a liquid me...

The Influence of Hematite on High Speed Continuous Casting of Steel Lubricating Powders: Viscosity and Crystallization

Mold powders used in the continuous casting of steel contain the harmful CaF2 as a main substance developing toxic gases such as SiF4 and HF at elevated temperatures. In this study, three samples of I1, I2 and I3, which contained gypsum free Portland cement clinker with different percentages of Fe2O3 (5.68, 6.83, 8.02 ...

Determination of some B Vitamins in Sour Cherry Juice Using Dispersive Liquid-liquid Microextraction Followed by High-performance Liquid Chromatography

Dispersive liquid-liquid microextraction method (DLLME) combined with high-performance liquid chromatography-ultraviolet detection (HPLC-UV) was used to determine thiamine (B1), nicotinamide (B3) and pyridoxine (B6) in sour cherry juice. This method was rapid, simple and sensitive. Separation was accomplished using a C18 column. The optimum chromatographic conditions were found to be: mobile ph...
