Title: Method and device for controlling continuous rolling mill
Inventor: TAKEI KUNIO
IPC: B21B37/20
Filed: 1986-02-22
Abstract: PURPOSE:To improve the load prediction accuracy and the rolled stock quality regardless of friction states by calculating an advancing ratio based on a screwdown load, the number of revolutions, a carrying-out speed, and the final plate thickness of each rolling mill and controlling each roll opening for a continuous rolling. CONSTITUTION:A measured advancing ratio is obtained by inputting a carrying-out speed 7 of each stand 2 and a peripheral speed of a rolling roll by a path generator 5 into an advancing ratio computing element 6. A thickness value by a thickness meter 8 in the outlet side of the final stand and a rolling load of respective stands 2 are measured by a load cell 3 and the computing element 6 calculates a calculated advancing ratio. Those measured and calculated advancing ratios are inputted into a computer 9 so as to correct the calculated advancing ratio and to control a rolling speed. A rolling load of each stand 2 is predicted based on the corrected advancing ratio in accordance with frictional states between a rolling roll 2 and a rolled stock 1 to control a roll opening. In this method, the load prediction accuracy covering all the fixed and sliding frictional ranges of respective stand 2 is improved and rolled stocks with stable quality are always obtained.

Abstract: PURPOSE:To shorten defrosting time and to alleviate damage to merchandise by providing a controller for outputting a control signal for controlling a motor- driven valve based on a measured value with an evaporating temperature sensor, and detecting the end of latent heat change in respect of an evaporator temperature by the use of the sensor at the time of defrosting through the controller. CONSTITUTION:tau1-tau2 indicate a defrosting time TD at a measuring temperature (evaporating temperature ET) of an evaporating temperature sensor 11 attached to an evaporator 5. There is period of latent heat change by holding at 0 deg.C when frost is melted during the same period. This is a period between points A and B, i.e., a period TD'' indicated by taua-taub. Accordingly, if the frost of the evaporator 5 is removed, latent heat change is finished, the temperature of the evaporator 5 is raised, and introduced to a heat sensitive change varying from 0 deg.C to positive temperature. This conversion point is sequentially detected at the temperature ET at a sampling time DELTAT, change rising from 0 deg.C is detected to know a period of defrosting. A signal of defrosting end is oscillated at a time point tau2 when the temperature ET is raised, for example, from the point taub of latent heat change end time, at +3 deg.C.
