钢铁研究学报(英文版)

Abstract： In order to study calcium leaching behavior for the steelmaking slag, factors that influence the leaching yield have been optimized. The results show that granularity of the slag, liquid to solid ratio (in short for L/S), temperature and reaction time have a significant effect on the leach...

关键词: Key words: steelmaking slag , leaching yield , calcium content

Establishment of Neural Network Prediction Model for Terminative Temperature Based on Grey Theory in Hot Metal Pretreatment

ZHANG Hui-ning , XU An-jun , CUI Jian , HE Dong-feng , TIAN Nai-yuan

钢铁研究学报(英文版)

In order to improve the accuracy of model for terminative temperature in steelmaking, it is necessary to predict and control before decarburization. Thus, an optimization neural network model of terminative temperature in the process of dephosphorization by laying correlative degree weights to all i...

Steel Temperature Compensating Model With Multi-Factor Coupling Based on Ladle Thermal State

WU Peng-fei , XU An-jun , TIAN Nai-yuan , HE Dong-feng

钢铁研究学报(英文版)

Combined with the parameters of the production process of a steel factory, numerical simulations for a new ladle from preheating to turnover are conducted using the finite element analysis system software (ANSYS). The measured data proved that the simulated results are reliable. The effects of prehe...

关键词: ladle , thermal state , multiple-factor coupling , numerical simulation , compensation model
