The aim of conducting this research was to evaluate the viscosity change in the continuous casting of steel mold powders by altering their chemical compositions, using hot stage microscope analysis. 4 low-fluorine samples containing such compositions as MnO, Fe2O3, Li2O, TiO2 and ZnO, as well as another fluorine-free sample containing a combination of Fe2O3 and TiO2, were prepared in this resea...

An experimental investigation has been carried out to study the cooling of a hot horizontal Stainless Steel surface of 3mm thickness, which has 800±10°C initial temperature. A round water jet of 22 ± 1C temperature was injected over the hot surface through straight tube type nozzles of 2.5-4.8mm diameter and 250mm length. The experiments were performed for the jet exit to target surface spacing...

Hot-pressed aluminium and silicon coated boron steel is used in the car industry where high tensile strength is of great importance, such as in the safety cage of a car where deformation has to be kept to a minimum in case of a collision. After hot-pressing the AlSi-boron steel shows excellent properties with high tensile strength, minimal spring back and also shows good protection against corr...

We investigate the experimental detection of the electromagnetic radiation generated in the fast magnetization reversal in Mn12–acetate at low temperatures. In our experiments we used large single crystals and assemblies of several small single crystals of Mn12–acetate placed inside a cylindrical stainless steel waveguide in which an InSb hot electron device was also placed to detect the radiat...

The production of clean steel involves the controlling, elimination, or modification of nonmetallic inclusions. In Al-killed steels, alumina is the main type of inclusion. Calcium treatment, by wire feeding, is commonly used to modify solid alumina inclusions to calcium aluminates, which exists in a fully or partially liquid phase. Liquid inclusions can improve steel castability, but make inclu...

Double layers composed of Sn and Mg, each 0.8 μm thick, were fabricated on a hot-dip galvanized steel (8.4 μm) sheet using DC magnetron sputtering post-annealing processes. With an increase in temperature, the surface morphologies agglomerated with other. Additionally, Sn/Mg mixture sites, including intermetallic compound Mg2Sn, formed at 190 °C locally clustered 220 °C. In salt-spray test, cor...

The objectives in the cold rolling process include improved sheet surface quality, enhanced steel mechanical strength, and better solidification operations. Given the increasing demand for higher steel...

This paper presents the model, solution method, and system developed and implemented for hot rolling production scheduling. The project is part of a large-scale e€ort to upgrade production and operations management systems of major iron and steel companies in China. Hot rolling production involves sequence dependent setup costs. Traditionally the production is scheduled using a greedy serial me...

Multiple linear regression equations predicting total skeletal muscle (TM) and total skeletal fat-free muscle (TFFM) weight were developed from data of 33 beef cows. Animals varied in weight (385 to 749 kg), age (3 to 10 yr), and fatness (.13 to 2.54 cm). A four-terminal impedance meter/plethysmograph measured resistance and reactance on the live animals, exsanguinated (bled) animals, and on th...
