Simulation of Material and Heat Balance of 150 t AOD Melting 430 Stainless Steel under Different Charge Conditions by Lu　Xiaohui, Kang　Congpeng, Chen　Hongzhi, Xu　Yongbin

“…Under this process condition， the consumption of ferrosilicon and lime reached 39.3 kg/t and 97.7 kg/t respectively， the continuous addition time of high carbon ferrochromium was about 12 min， the feeding rate was 4 t/min， and the maximum oxygen supply intensity at this time was 400 m3·min-1. By coordinating the relationship between oxygen supply and feeding rate， the temperature in the furnace was relatively stable； In the process of using dephosphorized molten iron + high chromium molten iron as furnace charge， the consumption of ferrosilicon and lime was 25.7 kg/t and 58.9 kg/t respectively. …”

Study on the Atomization and Dust-Reduction Performance of a New Type of External Pneumatic Vortex Fog Curtain Dust Removal Device in Fully Mechanized Excavation Face by Deji Jing, Rina An, Jingxu Chen, Shaocheng Ge, Liying Sun

“…It is found that the new type of external pneumatic vortex fog curtain dust removal device is relatively stable when the air volume at the pressure outlet is less than 400 m3/min. The dust-reduction efficiency of the new type of external pneumatic vortex fog curtain dust removal device was investigated through the dust-reduction experiment, and it is found that the new type of external pneumatic vortex fog curtain dust removal device had better dust removal performance under the condition that the ventilation conditions did not interfere with the integrity of the vortex fog curtain.…”
