The flow pattern in an opaque mold cannot be readily visible, and worker experience plays a major role controlling it, even though it has significant impact on slab quality continuous casting (CC) mold. An Eulerian–Eulerian two‐fluid model is used to comprehensively study the two‐phase of argon molten steel CC positions vortex centers upper/lower recirculation zones impingement point jet narrow face are identified their distribution analyzed. interactive effects speed, rate, immersion depth...
Strand electromagnetic stirring (SEMS) is widely applied in thin-slab continuous casting to promote the equiaxed crystal ratio (ECR). However, effects of alternate on evolution solidification macrostructure and ECR remain poorly understood. And formation region beneath stand equiaxed-to-columnar transition (ECT) have been overlooked most previous models. This study first introduces a novel equiaxed-columnar model comprehensively analyze casting. A complete feature slab, including strand,...
As an excellent reducing agent, lime has important role in the steel production process. Annular Shaft Kiln (ASK) been widely used industry for its low cost, footprint, high chemical activity, easy construction, and maintenance. Due to temperature generated inside ASK during operation, it is hard observe limestone decomposition process field distribution kiln. The simulation analysis of field, velocity calcination by CFD provides practical guidance future product quality control, design...
Quicklime is an essential reducing agent in the steel smelting process and its calcination from limestone accompanied by considerable energy consumption. As a relatively economical lime kiln, Parallel Flow Regenerative (PFR) kiln used as main equipment for production of quicklime various industries. PFR kilns generally use natural gas fuel gas. Although has high calorific value effective calcination, with increasing price pressure saves protect environment, it makes sense exploring cleaner...
Limestone of different particle sizes is often calcined together to improve production efficiency, but the calcination effect mixed size limestone difficult guarantee. To investigate combinations on calcination, this study uses a porous media model and shrinking core simulate process for single two in Parallel Flow Regenerative lime kiln (PFR kiln). The results show that an increase void fraction has small gas temperature. temperature also does not change with sizes. At same time,...
Feeding a cold steel strip into continuous casting (CC) mold is an effective method to improve the quality of large round bloom. However, it difficult assess correlation between bloom and initial temperature strip. Therefore, three‐phase mixed columnar–equiaxed solidification model developed evaluate effect feeding on macrosegregation structure in vertical CC The results show that induces “crystal rain” liquid core increases volume fraction equiaxed phase. After strip, flow direction molten...
A walking beam type reheating furnace with advanced control technology has been evaluated by combined energy and exergy analysis. In order to gain insight into the performance of present furnace, results analysis are compared those in published papers irreversibility is analyzed via destruction calculation. The show that slabs preheated before charged can save fuel improve utilization. structure material wall roof good thermal insulation. However, oxidized scale a little more temperature...
The two-fluid model (TFM) coupled with the kinetic theory of granular flow (KTGF) has gradually been used for modeling dense flows and mixing in rotating drums recent years. In present paper, a review is made from perspective development application. It found that several frictional viscosity models were proposed to consider enduring contact particles specific studied, but there still lack universal model. validated by various experiment results applicability indicated. investigating dynamic...
The main objective of this paper is to establish a mathematical framework analyze the complex thermal economic performance calcination process. To find factors affecting exergy efficiency loss, different destruction investigated in detail. Furthermore, flow cost model for saving has also been developed. results show that vertical shaft furnace self-sufficiency equipment without additional fuel required, but overall accounts 54.11% total input. In addition, energy waste heat recovery boiler...
