Title: Method for predicting surface roughing of continuously annealed steel strip
Inventor: YOSHIDA GENTARO
IPC: C21D9/56
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To facilitate the prediction of the occurrence of surface roughing by checking the ratio between the treatment velocity after deceleration and the critical treatment velocity. SOLUTION: With respect to a steel strip decelerated from the stationary treatment velocity V0 (m/min) in a soaking zone having a furnace temp. of Tf ( deg.C), the prediction of the occurrence of surface roughing after annealing is carried out as follows: the ratio between the treatment velocity V(m/min) after deceleration and the critical treatment velocity VCR(m/min) defined by equation, V/VCR' is computed, and the occurrence of surface roughing is not observed if the computed value is >=1. In the equation, D is sheet thickness(mm), T1 is sheet temp. ( deg.C) at the inlet of the soaking zone, T2 is sheet temp. ( deg.C) at the outlet of the soaking zone, and symbols a1 to a6 are constants.  Because the occurrence of surface roughing can be precisely predicted without tests directly after annealing by this method, the quality assurance of the steel strip with high reliability can be done with certainty.

IPC: H03M1/52
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To obtain a module which makes a quick response by providing a control means which controls the whole and generates a timing signal having its oscillation frequency accurately controlled, and generating a triangular wave signal on the basis of the timing signal and outputting an input signal to a control means after pulse-width modulation. SOLUTION: A control circuit 4 supplies the timing signal 102 to a triangular wave generating circuit 2a through an insulating circuit 5. The triangular wave generating circuit 2a generates the triangular wave 101a synchronized with the timing signal 102 and supplies it to an A/D converter 1. A pulse-width modulation A/D converter 1 imposes pulse-width modulation on the input signal 100a according to the triangular wave signal 101a to generate and inputs a pulse-width modulated signal 103 to the control circuit 4 through an insulating circuit 3. Consequently, the control circuit 4 obtains the pulse-width modulated signal 103 synchronized with the timing signal 102 supplied to itself. Consequently, the time constant of the filter of the input stage of the A/D converter 1 can be made small, so the response of the I/O module is made fast.
