Abstract: To predict the key performance index (compressive strength) of Iron ore pellets, a prediction model based on Kernel principal component analysis (KPCA) and RBF neural network was proposed. This paper determined the input variable through the analysis of the chain grate machine - rotary kiln - ring cold pellet.
Compressive strength (OST 14-3-72) is regarded as one of the principal criteria of suitability of roasted iron- ore pellets for metallurgical processing. One of the machines at the Sokolovsko-Sarbaisk combine (SSGOK) was used to study the effect of the roasting temperature routine on the strength ofunfluxed pellets.
The first results from the conjoined application of these techniques show that the cold crushing strength of the pellet increase with the decrease of porosity, the appearance of the fayalite, as well as the presence of magnetite-unoxidized. KEYWORDS: Cold crushing strength test, EBSD, iron ore pellet, microstructures.
RB 1000: automatic system for determination of the Cold Crushing Strength (CCS) of fired iron ore pellets and reduced iron ore pellets. ISO 4700 ASTM E 382.
Jan 11, 2005 . In this study effort has been made to correlate the cold crushing strength (CCS) of DRI with its apparent density. 2. Experimental. In this investigation two different types of DRI were test- ed which included the iron ore pellets reduced in the bed of carbonaceous reductants and iron ore reduced by carbon.
The reduction behavior and crushing strength of carbon-containing iron ore sinters (SI–C) prepared from coke oven gas (COG) tar have been examined with a quartz-made fixed bed reactor and with a tensile and compression testing machine, respectively. When an as-received iron ore sinter (SI) is heated at 10 °C/min up.
