【Abstract】 The influence of temperature and air excess factors on the quality of ferric oxide powder were analyzed.The optimum temperature range and relationship between the manual operation and fuel calorific value were deduced.The control model of air supply adapted to fuel calorific value was put forward.The results show that the production process is steady and the eligibility of ferric oxide powder increases from 60% to 90%.The economic benefit was promoted obviously.更多还原
