Abstract
1423752 Controlling converter steelmaking PENNSYLVANIA ENG CORP and AVRR 23 Feb 1973 [28 Feb 1972] 19182/75 Divided out of 1423751 Heading C7D A bottom-blown converter has flow-control means for at least one blast gas based on analysis of the exhaust gas by an infrared sensor which monitors CO, CO 2 and H20 content, and an oxygen content sensor employing a solid electrolyte ionically conducting to oxygen. In a preferred embodiment control of the whole process is carried out by a computer which, in addition to the initial data input for the heat, receives signals from an oxygen partial pressure analyzer 30, infrared sensor 31, and thermocouple 21, and in response selects appropriate gases to be blown in through submerged tuyeres mounted in box 14 and having coaxial passages for oxygen and hydrocarbon shielding gas, and through auxiliary tuyeres directed into the space above the bath. Various additives may also be entrained in the gas streams from the hoppers 40, 41. Furthermore the duration of blowing is controlled to obtain a desired final product.
