The Max Economic Profit Analysis Of Sintering And Refining Of Vanadic And Titanic Ore And Common Ore In Chengde I&S Co.

Chengde I&S Co. not only refines the common ore, but also the vanadic and titanicore and not only produces the common carbon steel, but also low alloy steel. So ChengdeI&S Co.'s profit is mainly decided by production costs of the common carbon steel andlowalloy steel, and by the change of the vanadic slag's selling price and different crudematerials and fuels and powers'price. This changes the costs and profit of the common oreand vanadic and titanic ore. The rate of the common ore and vanadic and titanic orechanges with the profit's change.
