Looking to see if I have the concept right . Thank you

20212 -202 A blast furnace makes pig iron containing 3.2% and 1.8% of Carbon and Silicon and remaining as Iron respectively. The ore is a combination of 80%, 12% and 8% of Iron Oxide, Silica and Aluminum Oxide respectively. The process requires coke at a rate of 1 Kg per kg of pig iron produced. The coke is adulterated with Silica with 10% of silica and remaining to be carbon. The flux is obtained at a rate of 0.4 kg per kg of pig iron and is the base of one tonne of pig iron containing pure Calcium carbonate. The blast furnace gas has 30% CO and 15% CO2. calculate the following assuming the 1. The weight of core used. 2.

Surpassed in hardness only by diamond, it is sometimes known commercially as carborundum. Silicon carbide is used primarily as an abrasive for sandpaper and is manufactured by heating common sand (silicon dioxide, SiO2) with carbon in a furnace.
