Abstract: PURPOSE: To detect the change of an interval to be detected with high accuracy by transmitting the change to a detector composed of a diaphragm filled up with a liquid and introducing the liquid discharged from the detector to a capillary tube, and then, detecting the length of the liquid column. CONSTITUTION: A holding body T and a transmitting element Ug are fitted to measuring points MP10 and MP20 attached to a clamping ring Kr and the holding body T has two cylinders Z which are arranged at an interval in the peripheral direction and have chambers Ka closed by a diaphragm V. When the torsional change ΔX caused by angular moment Dm generated between measuring points MP1 , and MP2 is transmitted to the diaphragm V through the element Ug, a liquid column change ΔY proportional to the torsional change ΔX is generated in the correlated capillary tube K. The change ΔY is electrically detected from the short circuit of a resistor W caused by the liquid column.  At the time of measuring the change ΔY, a desired magnification rate ΔY/ΔX is obtained by adjusting the ratio of the cross-sectional area of the diaphragm V to that of the capillary tube K.

Abstract: PURPOSE:To obtain control means for baking in a sintering machine in a lateral direction uniformly. CONSTITUTION:Thicknesses of an ore supply unit and an ore discharge unit at positions are measured in a lateral direction by a plurality of level gages 9-1, 9-2 mounted laterally at a material supply side of a sintering machine. A shrinkage factor of sintering ore is calculated from the measured results by a operator 10, and material charging densities of the ore supply unit in which lateral deviations of cold strength and porosity of the ore become minimum, are obtained. An opening of a dividing gate 3 is so regulated by a controller 11 as to become the charging density. Since the shrinkage factor of the ore is used as an index for laterally uniform baking, physical properties of the ore can be directly grasped, and the deviations can be accurately measured. The uniformity of the lateral baking can be performed to improve yield.
