properties of vanadium-titanium magnetite pellet CHEN Xuling, HUANG Yunsong, FAN Xiaohui, GAN Min (School of Minerals Processing and Bioengineering, Central South University, Changsha 410083, China) Abstract: The effects of different parameters such as size, preheating conditions and roasting conditions on the roasting characteristics of V-Ti magnetite pellet were studied. The results show that it is hard......
in lab, the effects of atmosphere on the strength of pellet prepared with hematite concentrate with carbon-burdened were studied, and the roasting behaviors and induration mechanisms under different..., overhigh or low oxygen partial pressure is unfavorable for recrystallization of Fe2O3, which causes a decrease of pellet strength. The original hematite will be transformed into magnetite on reduction......
of reductant material added, pellet size, duration spent in the furnace and the amount of unwanted contaminant material in the mixture [3]. Composite pellets containing sponge iron ore, coal and sodium...]. The binder is used for two main purposes: 1) to retain free water in the ore concentrate/iron oxide and 2) to prevent the dissolution of pellet or briquette. One of the most widely used binders......
iron than 2 % bentonite pellets. The testing results indicate that MHA binder is a promising and effective alternative to bentonite for the specularite pellets.Key words:iron ore; pellet; organic binder... pellets. The results show that there is stronger chemisorption between organic functional groups in MHA binder molecular and specularite particles, improving the green pellet strength. MHA binder has......
and Technology Beijing摘 要:Ludwigite is a kind of complex iron ore containing boron, iron, and magnesium, and it is the most promising boron resource in China... and differential scanning calorimetry analysis and isothermal reduction of ludwigite/coal composite pellet were performed. Ludwigite yielded a lower reduction starting temperature and a higher final reduction......
%. The moisture uptake of pellet decreases with the increment of bio-asphalt dosage, while the higher heating value of pellet is identified as an opposite trend. Furthermore, pellet fuel’s ignition temperature is reduced with the addition of bio-asphalt, which can improve the stability and continuity of pellet’s combustion. Key words: bio-asphalt; energy consumption; density; characteristics......
in cartilage repair extracellular matrix(ECM) materials under Hypoxia. C3H10T1/2 cell line, seeded as pellet or in ECM materials, was added with chondrogenic medium or DMEM medium for 21 days under hypoxia... the regulating roles of mi RNAs on angiogenesis. Results showed that the chondrogenic medium promotes chondrogenesis both in pellet and ECM materials culture. HIF1α was up-regulated under hypoxia compared......
concept of combining MgO crystal and buffer pellet was also introduced. The misorientation caused by the lattice mismatch between MgO and Gd123 melt was overcome by choosing suitable heat treatment program and Gd2BaCuO5 (Gd211) content of the buffer pellet. The doping effect of soft ferromagnetic NiFe alloy particles was also reported. The bulk sample with 0.4% (mole fraction) doping amount shows......
