Abstract: PURPOSE: To enable inferior-quality pellets to be effectively utilized as starting material for a blast furnace by successively laying sintered ore, the pellets and starting materials for sintering in layers on a grate in the manufacture of sintered ore to reform the pellets and mix them into the sintered ore.  
     CONSTITUTION: Sintered ore 12 as grate protecting bed ore is laid on grate 4 of a sintering machine from hopper 11 in a fixed thickness. This ore layer is covered with inferior-quality pellets 2, in a fixed thickness, which is singly unusable as starting material for a blast furnace to form a grate protecting bed. Starting materials 8 for sintering are charged onto the bed from hopper 5, fired in firing furnace 10, and sintered while being moved. Pellets 2 are heated to 1,400W1,500°C and absorb CaO from lower sintered ore 12 and upper starting materials 8. Accordingly, pellets 2 have increased contents of FeO and CaO as well as a raised reduction rate, and they are mixed into the resulting sintered ore and becomes well usable as starting material for a blast furnace.

Title: Wire-cut electric discharge machine
Inventor: INOUE KIYOSHI
IPC: B23H7/10
Filed: 1984-05-14
Abstract: PURPOSE:To make stable machining attainable in preventing a wire from breaking as well as to aim at improvements in machining efficiency ever so better, by detecting a discharging state lying between a wire electrode and a work, while controlling a brake to make for a direction where its tension is weakened in time of discriminating trouble states in an electric arc and a short circuit. CONSTITUTION:In a discharging state during operation, gap voltage is detected by a resistor 15, discriminated by a discriminator circuit 16, while a discriminating signal is fed to a control circuit 17 which controls a brake magnet 7. That is to say, when the discharge being carried out with an electrode gap shifts from normal to abnormal discharge, the discriminating signal fed out of the discriminator circuit 16 corresponds to this shifting and controls the magnet 7 so as to weaken its braking force and also weakens tension of a wire electrode 2, and when reaching to an arc short, it is controlled to the minimum tension. Thus the tension control carried out, tension during normal discharging is sufficiently raisable and, what is more, amplitude of a wire is controlled so small enough with strong tension and machining groove width is narrowed whereby an erosion rate is also raisable, thus such machining as being excellent in efficiency is made attainable.
