Title: Controlling method for continuous rolling mill
Inventor: ABE KAJI
IPC: B21B37/22
Filed: 1978-06-05
Abstract: PURPOSE:To automatically control the breadth at the final exit of the roughing mill to a specified value, by varying the tension between adjoining stands according to the deviation of the detected breadth of sheet on the exit side of the roughing mill from the set value. CONSTITUTION:When the sheet material arrives at the gaugemeter 40 at the exit side of the third stand ST3, the deviation of the actually measured sheet gauge from the set gauge value is delivered and is inputted to the operators 19, 29 and 38, 39. The output of the operator 29 is inputted to the driver 25 which then varies the tension between the second stand ST2 and the third stand ST3. Besides, this output is inputted to the driver 27 of the vertical roll mill E2, and the ratio of speeds of the vertical roll mill E2 and the horizontal roll mill R2 is kept at the initial set value. The output of the operator 19 is added to the output of the successive operator 30 by the adder 20, and the result is inputted to the driver 15 which then varies the tension between the first stand ST1 and the second stand ST2. On the other hand, the output of the operators 38, 39, are inputted to the roll gap controllers 37, 35, which then adjust the roll gaps of the vertical roll mill E3 and the horizontal roll mill R3.

Title: Glass-impregnated fiber-reinforced ceramics and production thereof
Inventor: SAKAI AKIHITO
IPC: C04B35/80
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To improve the oxidation resistance and room temperature strength of fiber reinforced ceramics in a high-temperature oxidizing atmosphere. SOLUTION: The glass-impregnated fiber-reinforced ceramics 7 are composed by including inorganic fibers 8 arranged in a prescribed direction and randomly, a ceramic matrix 9, enclosing the inorganic fibers 8 therein, integrally formed with the inorganic fibers 8 and having voids opened to the external space and a glass matrix 10 formed by closing at least the voids of the ceramic matrix 9 therein. Since the glass matrix 10 is capable of isolating the inorganic fibers 8 and the ceramic matrix 9 from oxygen in the atmosphere in a high- temperature oxidizing atmosphere, the oxidation is prevented to exclude a deteriorating factor in high-temperature strength based on the oxidation. Thereby, the high-temperature strength and the oxidation resistance are improved.  Since the strength deteriorating factor based on notch effects of the voids is excluded due to the densification by the impregnation of the glass, the room temperature strength is improved.

Filed: 1986-03-27
Abstract: PURPOSE:To surely prevent the crack at forging time with less yield loss by performing a welding repair by inspecting the surface flaw part after performing the scale removal of the ingot by a shot blast treatment, than by performing a forging after working the surface layer part only with low working rate at the initial forging stage time.

This working may be of the degrees that the forging ratio on the outmost face of the ingot after its working becomes >=4. Concretely a sufficient effect can be obtd. only by applying such work as reducing the diameter with the thickness of about >=50mm from the surface in case of the ingot with 750mmphi diameter. In this way, the slab, billet, etc. of titanium or titanium alloy can be formed with less yield loss and hardly causing a crack.
