Nozzle blockage in continuous casting of al-killed SAE 1006 and SAE 1008 grades in Iskenderun Iron and Steel Works

Sakallı, Erhan
In this work, nozzle clogging in the submerged entry nozzle in continuous casting of Al killed steels has been studied. The study has been based on low silicon Al killed SAE 1006 (1.2006) and SAE 1008 (1.2008) grades. In this study, castabilities of 75 heats for 1.2006 steel grades and 75 heats for 1.2008 steel grades have been investigated. Castabilities of the experimental heats have been found to be affected by Al content in oxide form (Aloxy) and Ca content of the liquid steel. Castabilities have been found to decrease with increase in Aloxy and to increase with increase in Ca content and Ca/Aloxy ratio. Reoxidation has been found not to affect the castability appreciably.


Nanomorphology and fire behavior of polystyrene/organoclay nanocomposites containing brominated epoxy and antimony oxide
Isitman, Nihat Ali; Sipahioglu, B. Melike; Kaynak, Cevdet (Wiley, 2012-06-01)
Organoclay nanocomposites were prepared by ultrasound-assisted solution intercalation technique based on polystyrene containing brominated epoxy and a combination of brominated epoxy and antimony oxide. Aspects of nanomorphology and nanodispersion were investigated by X-ray diffraction and transmission electron microscopy whereas flammability and reaction to fire were evaluated using limiting oxygen index, UL-94, and mass loss calorimeter tests. Polystyrene/brominated-epoxy-blend-based nanocomposites showed...
Compressive strength development of calcium aluminate cement-GGBFS blends
Kirca, Onder; Yaman, İsmail Özgür; Tokyay, Mustafa (2013-01-01)
The compressive strength development of calcium aluminate cement (CAC) and ground granulated blast furnace slag (GGBFS) blends that were subjected to different curing regimes are investigated. The blends had GGBFS/CAC ratios between 0% and 80%, by mass. Mortar specimens, prepared with a water:binder:sand ratio of 1:2:6, were subjected to seven different curing regimes and the compressive strengths were monitored up to 210 days. In order to understand the effect of temperature on compressive strength develop...
Filtration testing of a ceramic capillary filter produced from a high-silica glaze
San, O; Hoşten, Çetin (2002-07-01)
A laboratory procedure for the production of a ceramic capillary filter from a high-silica glaze was described and its filtration response was tested in dead-end and periodic vacuum filtration modes with suspensions containing micron and sub-micron clay particles obtained from a ceramic factory wastewater stream. The same glaze raw material ground to two different levels of fineness was used for the production of the porous ceramic substrate and its surface coating. The coating particulate sol was deposited...
Hot Cracking Susceptibility of Twin Roll Cast Al-Mg Alloy Welds
Tirkes, Sueha; Batıgün, Caner; Ankara, Alpay (2010-01-01)
The hot cracking susceptibility of two different Al-Mg alloys during welding at various applied strains was investigated. At each strain value, the amount of hot cracking susceptibility increased with increasing magnesium content. Thermal analysis results verified that hot cracking susceptibility indeed call be related to the solidification range. As suggested in the solidification range approach, the results of the present Study confirm that the extent of solidification and liquation cracking depend oil th...
Kinetic investigation of chemical vapor deposition of B4C on tungsten substrate
Karaman, Mustafa; Sezgi, Naime Aslı; Doğu, Timur; Ozbelge, H. Onder (2006-12-01)
Production of beta-rhombohedral boron carbide (B4C) on a tungsten substrate by the chemical vapor deposition from a BCl3-H-2-CH4 gas mixture was achieved. An impinging-jet reactor was used to minimize the mass-transfer limitations on the reaction kinetics, which made a detailed kinetic investigation possible. Results of the XRD and XPS analyses showed that the solid product formed on the substrate is a rhombohedral B4C phase. Both dichloroborane and boron carbide formation rates were found to increase with ...
