Filed: 1993-12-09
Abstract: PURPOSE:To improve the productivity of operation in an electric furnace and reduce various kinds of the unit consumptions by automatically measuring and controlling slag-foaming height in on-line at the time of refining a steel in the electric furnace. CONSTITUTION:A distance sensor 1 for measuring the distance (l1) between a furnace roof and the slag surface is arranged at the furnace roof 2 in the electric furnace 3. The slag surface height (l2) during the operation in the electric furnace 3 is treated with a data operation processor 21 and calculated by always measuring the (l1) value in the refining period, and by using the distance to the steel bath 18 surface measured at the initial stage of the operation as the reference. In the case the foaming slag 14 during the operation does not cover the arc 19, the carbon powder is automatically added from a blowing hopper 16 so that the measured foaming slag height (l1) corresponds to the objective value of the preset arc length. Further, in the case the slag 14 excessively covers the arc 19, aluminum ash is added to reduce the foaming height. By this method, the suitability of charged voltage in the refining period and the improvement of the productivity, etc., are obtd.

Filed: 1994-12-13
Abstract: PURPOSE: To directly and automatically measure a tail clearance by vertically erecting a pole member while its tip is kept in contact with the inner periphery of a skin plate, supporting the measured face of a rigid member in parallel with the inner periphery of the skin plate, fixing a fitting base to a pressing member while an extruding spring is compressed, and selecting the length of the pole member and the length of a gap. CONSTITUTION: The measured face 15a of a rigid member 15 is invariably kept in parallel with a skin plate 2 by a spring 13. The tip of a pole member 21 is brought into contact with the skin plate 2 by a spring 17. The length L1 of the gap G between the measured face 15a and the pole member 21 is measured when the measured face 15a is brought into contact with a segment 5. The distance between the segment 5 and the skin plate 2 is calculated based on the length L1 of the gap G and the length L21 of the pole member 21. The thickness L5 of the segment 5 is subtracted from this distance. The distance between the inner periphery of the skin plate 2 and the inner periphery of the segment 5 is directly measured, thus an accurate tail clearance can be automatically measured regardless of the deformation of an excavator.

Filed: 1999-11-01
Abstract: PROBLEM TO BE SOLVED: To extract and reuse a surfactant-containing inorganic salts and having surface activation functions from an oilcontaining alkaline degreasing solution. SOLUTION: A used oil-containing alkaline degreasing solution W1 is supplied to an emulsification tank 20. Voltage is applied to electrode plates 22 made of a metal net to generate foams. The oil emulsification is further promoted by the foams. Some of the oil and dust contained in the alkaline degreasing solution W1 are included in the foams at the time when the solution passes through the electrode plates 22 of the metal net to be floated and removed and the heavy dust passes through the gaps 21b of partitioning members 21 to be precipitated and removed. The alkaline degreasing solution W2 passing through the emulsification tank 20 is mixed with a surfactant from an additive tank 60 to further promote emulsification of the oil.  At the time when the alkaline degreasing solution W4 mixed with the surfactant passes through an inner pressure circulation type hollow-fiber membrane module 70, an inorganic saltcontaining alkaline degreasing solution W5 is allowed to permeate and taken out to the outside to be reused. In this case, since the oil in the solution W4 passing through the inner pressure circulation type hollow-fiber membrane module 70 is emulsified and finely granulated, no oil adhesion takes place and no clogging is caused.
