This research was conducted to study the effect of lime based Flux with the composition of CaO-20%CaF2-8%FeO on simultaneous removal of phosphorus and Sulfur from hot metal. The effects of Na2O and oxygen blowing were also studied. The experiments were performed using an induction furnace and hot metal produced in Isfahan Steel Company in the temperature range 1350-1450 ºC...

Abstract The accurate description of friction is critical in the finite element (FE) simulation sheet metal forming process. Usually, oversimplified through use a constant Coulomb coefficient. In this study, application an existing multiscale model extended to hot stamping accounts for effects tool and surface topography as well evolution contact pressure, temperature, bulk strain during stampi...

Hot metal desulfurization is the main process step for removing sulfur in blast furnace-based steelmaking. A reagent pneumatically injected into hot through a submerged lance causing it to vibrate. The aim of this study was develop mechanical vibration measurement-based method that can detect changes gas-forming properties reagent. detection performed using Elastic Net regression and eXtreme Gr...

We use cosmological hydrodynamic simulations with unprecedented resolution to study the formation of primordial stars in an ionized gas at high redshifts. Our approach includes all the relevant atomic and molecular physics to follow the thermal evolution of a prestellar gas cloud to very high densities of ∼ 10cm. We locate a star-forming gas cloud within a reionized region in our cosmological s...

A fire detector is the most important component in a fire alarm system. Herein, we present the feasibility of a highly sensitive and rapid response gas sensor based on metal oxides as a high performance fire detector. The glancing angle deposition (GLAD) technique is used to make the highly porous structure such as nanocolumns (NCs) of various metal oxides for enhancing the gas-sensing performa...

New CO observations at the center of cooling flow in Perseus cluster [4] show a clear correlation of the molecular gas with the previously detected H-α filaments [1]. In this poster, we present high resolution multi-phase simulations of the Perseus Cluster, taking into account the AGN feedback in form of hot buoyant bubbles. These simulations show that significant amount of gas can cool far fro...

We present a schematic model for the formation of baryonic galactic halos and hot gas in the Local Group and the intergalactic medium. We follow the dynamics, chemical evolution, heat flow and gas flows of a hierarchy of scales, including: protogalactic clouds, galactic halos, and the Local Group itself. Within this hierarchy, the Galaxy is built via mergers of protogalactic fragments. Hot and ...

We study the nature of low-redshift CGM in Simba cosmological simulations as traced by ultraviolet absorption lines around galaxies bins stellar mass ($M_\star>10^{10}M_\odot$) for star-forming, green valley and quenched at impact parameters $r_\perp\leq 1.25r_{200}$. generate synthetic spectra HI, MgII, CII, SiIII, CIV, OVI, fit Voigt profiles to obtain line properties, estimate density, tempe...
