Title: Production of austenitic stainless steel thin sheet excellent in surface quality
Inventor: SUEHIRO TOSHIYUKI
IPC: B24C1/06
Filed: 1995-04-06
Abstract: PURPOSE: To produce an austenitic stainless steel thin sheet excellent in surface quality, in a synchronous continuous casting process, by specifying its compsn. and prescribing cumulative drafts in hot rolling and cold rolling after casting. CONSTITUTION: In a continuous casting machine in which a slab is moved in synchronism with the circumferential face of a cooling drum in which random dimples are largely scattered by a shot blasting method, an austenitic stainless steel thin strip slab is cast. At this time, the compsn. of this slab is regulated to the one in which Cr equivalent defined by Cr+Mo+1.5Si and Ni equivalent defined by Ni+30 (C+N)+0.5(Mn+Cu) satisfy the inequality. After the casting, it is subjected to hot rolling for one pass at <=15% rolling ratio, is water-cooled and is thereafter coiled at <=600 deg.C to form into a thin strip slab, and descaling is executed.  Next, it is subjected to cold rolling for one pass at a rolling ratio so as to satisfy the cumulative draft with the rolling ratio of the same hot rolling to 25 to 40%, is, if required, subjected to process annealing and cold rolling and is thereafter subjected to annealing and pickling or bright annealing.

Title: Method for regulating leveling of rolling mill
Inventor: ENDO MASATOSHI
IPC: B21B31/20
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To regulate the leveling with excellent accuracy by using an aluminum plate for a roll gap measurement plate to improve the measurement accuracy of the roll gap. SOLUTION: The desirable properties of a measurement plate are that the coefficient of friction is not changed by the rust on the surface, the spring back after the reduction is less apt to generate, and the yield strength is appropriate. If the reduction load is 1500 ton, the yield stress is preferably 15-30 kgf/cm<2> . Measurement plates 1a, 1b are fixed to a rectangular frame 7, and loaded on a lower roll 2 of a rolling mill, and the measurement plates 1a, 1b are arranged at the specified positions on the operation side and on the drive side. The rectangular frame 7 is of the shape in which a circumferential surface of the roll 2 is locally inscribed. The measurement plates 1a, 1b are stationarily reduced by upper and lower work rolls.  The position of a reduction screw during the reduction is recorded to obtain the difference in the position between the operation side and the drive side. The thickness of the measurement plates 1a, 1b is measured to from the roll gap, and the differential roll gap between the operation side and the drive side is obtained.

Filed: 1979-06-29
Abstract: PURPOSE:To ensure the effective use of the information, by discriminating whether the information which is transmitted after detecting the first sentence of the information given from the master unit at each slave unit and by the time supervisory is sent from the master unit or the slave unit in case the semidouble synchronous communication is carried out with n-units of slave units connected to the master unit. CONSTITUTION:The information is collected via n-units of slave units connected to the master unit. And the 1-byte information received at a certain slave unit from the master unit is supplied to serial-parallel converting part 3 via interface 2. Timer 4 is triggered by the end of reception and then turned to the L level. And when the coincidence is detected to the own address at coincidence circuit 5 at the H level and in the first byte, control circuit 8 works. And thus timer 4 is also triggered at the end of reception of the second byte, and the data transmission is started from the slave unit to the master unit after reception. Other slave units which have no address coincidence receive their transmission data. But they never receive the data as the transmission data from the master unit by controlling the set time since timer 4 is triggered by the transmission byte of the second byte sent from the master unit.
