Title: Method of neutralizing waste water generating in aging treatment of electric furnace slag using carbon dioxide gas
Inventor: KIM HYEONG SEOK
IPC: C21C5/28
Filed: 1998-12-24
Abstract: PURPOSE: A method is provided to neutralize alkali waste water generating in aging slag from an electric furnace by using carbon dioxide. CONSTITUTION: Waste water generating in aging slag from an electric furnace is neutralized by spraying carbon dioxide to the waste water. Carbon dioxide or waste gas containing carbon dioxide is used as gas sprayed for neutralizing waste water. The slag in an electric furnace is aged by the reaction of glass lime to moisture contained in the slag. Alkali calcium hydroxide is generated by the reaction of oxidized calcium contained in the slag and in unstable state to water by the equation, CaO+H2O becomes Ca(OH)2. Calcium hydroxide is contained in the water used for aging according to aging the slag. The waste water generating in aging is alkali.

Abstract: PURPOSE: A position of sensing system and the method are provided to sense the correct position of a crane by assuming the moving distance of the crane with a moving distance converting factor due to the number of pulses from an encoder, the diameter of a hoisting drum and a trolley wheel and the number of motor rotations. CONSTITUTION: A moving distance of a hoisting drum(13) in one rotation is calculated by a formula which is (pi)x(the diameter of the hoisting drum). An estimating unit(41) for a moving distance converting factor calculates the number of pulses from a hoisting encoder(14) while the hoisting drum is rotated one time. The number of pulses is calculated by a formula which is (the number of a hoisting motor rotations during one time of a hoisting drum rotation)x(the number of pulses from the hoisting encoder during one time of the hoisting drum). After the calculations, the estimating unit calculates the moving distance of the hoisting drum during one pulse of the hoisting encoder. Therefore, the real position of a crane is assumed by accumulating the results of the calculations.
