The present status, uses and future prospects of the oxygen sensors are summarized and critically reviewed. Domestic research of the oxygen probes regarding the historic development, probe design and tentative application in steelmaking is briefly discussed. As a means to control the steel-making process, to improve the quality of ingots, to minimize the expenditure of ferroalloys and so forth, uses of the oxygen sensors applied to the following aspects are comparatively fully discussed: (1) control of end point...

The present status, uses and future prospects of the oxygen sensors are summarized and critically reviewed. Domestic research of the oxygen probes regarding the historic development, probe design and tentative application in steelmaking is briefly discussed. As a means to control the steel-making process, to improve the quality of ingots, to minimize the expenditure of ferroalloys and so forth, uses of the oxygen sensors applied to the following aspects are comparatively fully discussed: (1) control of end point of blowing with the LD-process; (2) control of deoxidation in semikilled and rimming steels; (3) estimation of residual aluminum in killed steel during the continuous casting; (4) control of form of sulfide inclusions in freecutting steels; and (5) on-line use of oxygen sensors in steelmaking combined with computer. In the last part of the paper, the confronting problems and error sources of the oxygen probes, particularly in connection with the electronic conductivity and thermal shock resistance of the solid electrolyte and means of increasing accuracy in measurement of low oxygen activity, are discussed. In addition, brief mention is made of the possibility of development of other sensors for determining other elements such as nitrogen, hydrogen, su(?)ur and carbon.

A series of full-scale experiments were made for studying mainly the effect of turbidity,water temperature,and pH value on aluminum removal in the process of coagulation/sedimentation.The tests show that aluminum removal can be divided into the reduction of dissolved aluminum and the removal of particulate aluminum.Residual turbidity has linear relation to residual aluminum within certain limits of concentration,and then removal of particulate aluminum can be achieved effectively while turbidity is removed.The optimal pH value varies with temperature,and adjustment of pH value is beneficial to the decrease of dissolved aluminum and increase of the potential removal of aluminum.On this basis some proposals have been offered for operation of water plant.
