Description
Technical field
The utility model relates to the online bistrique of a kind of hot roll, specifically, is a kind of bistrique that has grinding force and have online roll shape measuring ability.
Background technology
Hot roll on-line grinding technology with improve the quality of products and productivity ratio be aim, can prolong the roll change cycle, improve milling train plate shape control function and plate product quality, eliminate each passage rolling in work roll diameter section poor and improve the free degree of various width belt steel rolling plan.Hot roll on-line grinding device operated by rotary motion is in the upper and lower working roll of frame porch, and online reconditioning working roller in the rolling gap or the operation of rolling is so that it keeps higher roll shape precision and surface roughness.
Bistrique is as the core institution of on-line grinding device, play an important role, the grinding function of on-line grinding device is mainly finished by bistrique, in order to give full play to its effect, bistrique must be under the cooperation of roll profile on-line measuring device, just can make operating personnel grasp the roll shape situation of working roll in time, exactly, only avoid grinding by rule of thumb and cause that ground effect is not good, the situation of bistrique fault.Because the operating ambient temperature of hot rolling roll shape on-line measuring device is higher and fluctuation range is big, roller surface is by mobile cooling water covering and have iron scale, and influence that factor causes such as the vibration, strong electromagnetic, the steam fog that have roll and sensor that stand is installed fill the air, installing space is narrow and small, greatly influenced stability, accuracy and the reliability of checkout gear.Therefore, conventional optical detecting method is difficult to obtain practical application, and the hot rolling roll shape on-line measuring device of development high-resolution, high reliability is still a global difficult problem.
Existing roll shape on-line measuring device, generally displacement transducer detects roll profile by adopting independently, more representational is the ultrasonic displacement telemetry that Mitsubishi Heavy Industries Ltd adopt, the advantage of ultrasonic sensor is anti-electromagnetism, the interference performance of light is stronger, measuring distance is bigger, but be subjected to temperature, the influence of factors such as propagation medium is big, for making the homogenization of sonic transmissions medium, also to adopt coupling water column as hyperacoustic propagation medium with certain pressure and constant flow rate, in addition, also must be provided with on the device independently along roll feed mechanism (gear radially, the tooth bar transmission), and take multiple error compensation means, the testing circuit complexity, therefore, effect is unsatisfactory in actual applications.
In order to overcome the shortcoming that adopts displacement transducer independently directly to measure roll profile, in recent years occurred by the method for measuring grinding force and roll profile indirectly that contacts of emery wheel with roll, be the function that bistrique itself just has online detection, mainly contain following two kinds of methods:
In the CN1080218A patent of Hitachi's application in 1993, propose to adopt the online bistrique of the discoid emery wheel of thin plate.The used emery wheel of this bistrique is a flexible abrasive wheel, emery wheel produces distortion under the effect of axial grinding force, because the supplying position of bistrique is fixed, so the deflection of emery wheel is the variable quantity of roll shape coordinate, because the coefficient of elasticity of emery wheel is known, axial grinding force during wheel grinding is then detected by the pressure sensor that is installed in emery wheel driving shaft rear end, can be regarded as out the deflection of emery wheel thus, and extrapolates the roll shape coordinate of roll.Because emery wheel driving shaft rear end is provided with pressure sensor, emery wheel drives and has therefore adopted belt gear, increased taking up room of mechanism on the one hand, made structure become complicated, on the one hand after speed improves, cause belt creep easily, grinding speed is not increased, and make the grinding speed instability, thereby directly cause ground effect not good, therefore, the actuating speed of emery wheel is restricted; In addition, the flexible abrasive wheel structure has not only limited the grinding capacity of emery wheel, and causes the fatigue failure of emery wheel easily, thereby directly influences the service life of emery wheel.
Broadcast in the JP9066306 patent of mill application on the Ishikawa island, the transmission mechanism in the transmission mechanism of bistrique and the above-mentioned CN1080218A of the Hitachi patent is similar, also is to adopt belt gear, and is provided with sensor in the rear end of emery wheel driving shaft.What but this device adopted is displacement transducer, in order to the axial displacement of on-line measurement emery wheel driving shaft in grinding process, axial displacement is the variable quantity of roll shape, can draw the roll shape coordinate of roll thus, simultaneously, on the emery wheel driving shaft spring assembly is set, according to the coefficient of elasticity of spring, shaft is to grinding force at last.This device adopts belt gear on the one hand, have with the identical shortcoming of Hitachi's CN1080218A patent, adopt displacement transducer to measure the displacement of power transmission shaft on the other hand, because displacement is a micron order unit, therefore, in the working environment at hot rolling scene, the sensitivity of sensor and reliability are difficult to be guaranteed.
