Title: Method for controlling hearth temperature in blast furnace
Inventor: MORIYA KATSUSHI
IPC: C21B5/00
Filed: 1987-10-28
Abstract: PURPOSE:To prevent variation of hearth temp. by calculating a settling index at furnace core, predicting change of the hearth temp., changing height of fusing zone and pressure loss in the furnace, etc., and controlling the settling index at the furnace core. CONSTITUTION:At first, the settling index at the furnace core indexing the degree, which the furnace core settles into basin at lower part of the furnace, is calculated from the equation. Successively, the index value to become the critical point whether the furnace core flats up or not is found from the relation between this index and the hearth temp. When the settling index at the furnace core is changed to the critical point, the height of the fusing zone and/or the pressure loss, etc., in the furnace are changed to adjust the settling index at the furnace core and control the hearth temp. By this method, the variation of the hearth temp. is prevented and the stable operation can be executed.

Title: Putrefaction prevention control method for aqueous fluid
Inventor: MATSUMOTO SHINICHI
IPC: G01N33/10
Filed: 1993-11-04
Abstract: PURPOSE:To make it possible to appropriately control the putrefaction prevention by measuring the variation with time in the quantity of oxygen dissolved into an aqueous fluid filled in an open system vessel and then predicting the extent of putrefaction of the fluid based on the measurements. CONSTITUTION:The quantity of dissolved oxygen(DO) is measured continuously in time for an open system vessel filled with a fluid into which a required quantity of oxygen is dissolved constantly. When the temporal value of DO is in decreasing process, it means a sign of corrosion occurring in the fluid and when the temporal value of DO approaches 0, it means positive proceeding of putrefaction. When the temporal value of DO is kept horizontal or increases after temporary decrease, it means that the fluid is controlled normally or the putrifaction has stopped and the properties of the fluid are recovered. Required control processing are performed by predicting the proceeding of putrefaction based on the measurement result of values DO in the fluid and recovering the properties in the early stage.
