Converting Simulation of the PS Copper Converter

Computer Simulation of Ammonia Cold Shot Converter

A mathematical model is developed and tested with plant data for the ammonia cold shot converter of Razi Petrochemical Complex. The model is based on a material and energy balance in a differential element of beds and is subjected to the assumptions of uniform distribution of temperature and composition through a general cross section and negligible mass and heat transfer in axial direction. Th...

Soft-switching Ps-pwm Dc-dc Converter for Arc Welding

Soft-switching DC-DC converter using Phase-Shifted Pulse Width Modulation (PS-PWM) on secondary side of highfrequency transformer is described in the paper. The converter consists of a full-bridge inverter fitted with fast IGBT transistors. The output power of the converter is controlled by rectifier made up of two snap-off diodes in series with MOSFET transistors which is connected on secondar...

Large Eddy Simulation of Bubbling-Jetting Transition in a Bottom Blown Copper Converter

In this work the isothermal transition from bubbling to jetting regime in a bottom blown Peirce-Smith copper converter is numerically studied, varying the air jet injection velocity from 5 to 100 m s -1 . Large Eddy Simulation turbulence model is employed in the computer simulations to obtain transient, rather than averaged, phase distributions. For low injection velocities the bubbling regime ...

The Fracture Mechanisms of an Austenitic Heat Resisting Steel in Copper Converter Atmosphere

The openings of Copper converter in Sarcheshmeh Copper Complex in Iranis made of a heat resisting austenitic steel (Fe-25Cr-12Ni) and many failures have been reported. Understanding the failure mechanism of the alloy helps to develop better alloys for similar complex environments. Samples of as-cast alloy and those taken from failed ones were examined. Optical Microscopy (OM), X-Ray Diffraction...
