Electronic overspeed switch EGS 41 ensures safe rolling mill operations

Hot Rolling Mill, Steel & Rolling Mills

For precise speed control in rolling mills the main drives of the roll stands and the coilers need to be equipped with an encoder. In addition, it is often necessary to provide increased protection for personnel during special operating modes, such as: For this application Johannes Hübner Giessen has been working with Motor OEMs for many decades to provide complete solution ie. Electrical and mechanical components.

Challenges For precise speed control in rolling mills the main drives of the roll stands and the coilers need to be equipped with an encoder. In addition, it is often necessary to provide increased protection for personnel during special operating modes, such as: Setup procedures with rotating rollers Maintenance work under electrical voltage The risks of such situations can be significantly reduced by implementing the safety function “Safely-Limited Speed” (SLS). SLS can be realized by using an overspeed switch that operates independent of the encoder and fulfils the special safety requirements (Safety Integrity Level SIL / Performance Level PL). Electronic overspeed switch EGS 41 mounted on an incremental encoder FGH 6. Solution To meet these requirements Johannes Hübner Giessen supplies the overspeed switch EGS 41, which is certified up to SIL 2 to IEC 61508 and PL d to DIN EN ISO 13849. In addition to two safe switching outputs for speed monitoring of overspeeds and underspeeds it offers integrated standstill functionality as well as an integrated diagnostics switch to monitor safety functions integrated in the device. The programming software included in the scope of supply supports user-friendly parameterization via a USB interface.

Challenges Loopers are normally used to control the tension of the metal strip between roll stands. The rotational angle of the looper is measured by a feedback encoder that is exposed to special demands. The setting angle up to only about 45° results in a partial load on the encoder bearings in conjunction with insufficient bearing lubrication. The encoder is subject to high levels of shock and temperature loads as well as oil / cooling emulsions / water at the place of installation. Formerly used standard encoders have not reached the required lifetime. Looper encoder with heavy-duty ball bearings and special lubrication for long lifetime. Solution For this application Johannes Hübner Giessen developed a special looper encoder, which boasts a considerably longer lifetime thanks to especially designed-in features. These contain oversized bearings with the dynamic load rating increased by 40 % as well as a special radial shaft sealing ring with an additional protective lip. To guarantee the best signal quality the bearings are not primarily designed for high speeds, but rather for high shock loads up to 450 g.

It solves the serious problem of overheating, blistering and cratering. The rugged optics allows it to operate it at very high ambient temperature without cooling, with accurate temperature control. Reliable coats and minimum injections are produced as the output. Home Case Studies Temperature Monitoring during Tablet Coating process Temperature Monitoring during Tablet Coating process Home Case Studies Pilger mill in tube rolling mills – hot and cold pipe detection Pilger mill in tube rolling mills – hot and cold pipe detection Continuous temperature measurement during the table and capsules coating process resulted in reliable coats and minimum rejections. Sensor output was used as a feedback signal to the air supply for air and temperature control Improved operational efficiency with reduced risks of defects during the tablet coating process Highly accurate and precise temperature control during the coating process Increases process efficiency and consequent production quality, yield and speed Challenges Overheating during the tablet coating process can cause various challenges such as blistering, cratering, pitting, blushing, sticking and picking. High temperature can cause gases to be trapped under the film during the spraying process or at the end of the coating run. Other defects such as cratering may appear exposing the surface of the tablet. High coating temperatures can also cause white specks or haziness to appear on the film. Sometimes pits may occur in the tablet core without a noticeable defect on the on the coating. Tablets may stick to each other and to pan walls. Solution Compact series, contactless IR pyrometer with electronics inside the cable and M12 construct sensor head is ideally suited for this application.

Monitoring of a strip roller path

Tubes and Pipes

Hot metal detector from Proxitron was installed to detect objects precisely and safely, even if tube diameters were changing. It accurately monitored strip roller path. It offered high repeatability and reliability, while having adjustable measuring rate. Home Case Studies Monitoring of a strip roller path Monitoring of a strip roller path Home Case Studies Pilger mill in tube rolling mills – hot and cold pipe detection Pilger mill in tube rolling mills – hot and cold pipe detection Hot metal detector from Proxitron was installed to detect objects precisely and safely, even if tube diameters were changing. It accurately monitored strip roller path. It offered high repeatability and reliability, while having adjustable measuring rate. Challenges Accuracy of tube length measurement depends upon the ability to detect the beginning and ending of tubes. A tube rolling mill required length measurement directly at the conveyor track. Simple commissioning, high repeatability and a integrated error monitoring system were needed. Furthermore, tubes of different sizes were in production Solution Different tube diameters lead in a V-conveyor to a very divergent height position of the pipe. Therefore the tube beginning and end couldn’t be detected with a light barrier. However, HMD from Proxitron detects objects in a field within the barrier height. This ensures the safe detection of the tubes, even if the tube diameters are changing. If a tube is detected by the light grid, the counter in the system control is set to zero. By means of an incremental rotary transmitter which runs with the tube, exact length measuring up to +/- 1mm is possible. The HMD works as a light barrier with 10 single lines in the grid of 8 mm. The invisible infrared radiation between transmitter and receiver scans a height of 75 mm on entering material. A contamination output at the light grid ensures a reliable production even under extremely dusty or dirty conditions. The intermittent short circuit protection protects both outputs in case of overload. Proxitron HMDs are available with a barrier width from up to 1400 mm.

Temperature monitoring of the pusher arm wall using ratio pyrometer

Iron Making, Steel & Rolling Mills

Effectively maintaining temperature of the heating chambers in the coke oven battery is essential for high yield and optimum quality of the coke. The narrow width of the flue makes it challenging for the accurate measurement of the flue temperature using a portable pyrometer inside the pusher arm as the hot coke is pushed out of the oven. Successfully monitoring the temperature of the heating chambers also reduces risk of damage to the oven wall. Home Case Studies Temperature Ctratio Temperature monitoring of the pusher arm wall Home Case Studies Pilger mill in tube rolling mills – hot and cold pipe detection Pilger mill in tube rolling mills – hot and cold pipe detection Fibre optic based pyrometer installed inside the pusher arm to measure the temperature of coke oven walls profile as the hot coke is pushed out. Typically six numbers are fitted to pusher arm (three each side). Increased quality: High quality metallurgical coke results in improved iron and steel making process Better coke yield: Critical for good quality coke, the oven and heating chambers in coke oven battery are effectively controlled Challenges Effectively maintaining temperature of the heating chambers in the coke oven battery is essential for high yield and optimum quality of the coke. The narrow width of the flue makes it challenging for the accurate measurement of the flue temperature using a portable pyrometer inside the pusher arm as the hot coke is pushed out of the oven. Successfully monitoring the temperature of the heating chambers also reduces risk of damage to the oven wall. Solution Fibre optic-based pyrometer was installed inside the pusher arm to measure the profile temperature of coke oven walls as the hot coke is pushed out of the oven. The 2-color ratio technology allows accurate and repeatable temperature measurements free from dependence on absolute radiated energy values. 2-color sensors measure closer to the highest temperature within the measured spot (spatial peak picking) instead of an average temperature. Due to its short measuring wavelength the ratio pyrometer was used. Given the harsh operating environment the pyrometer is resistant to dust, steam and dirt and gives accurate measurements even in cases of window soiling of up to 90 percent. Rugged and electrically isolated sensing head Long length of fibre optic cable (3|6|10|15|22 meters available) Small sensor head dimensions M40 makes it ideal for hard to access areas Temperature range of 500⁰C -1800⁰C Tolerant to dirty environment as 5% FOV coverage is sufficient for accurate measurement Pyrometer could withstand high ambient temperature of 315⁰C for optic head with fibre optic cable The short response time was ideal for the monitoring of very fast processes Products and Accessories Next Generation Pyrometer: Dirt & Steam Resistant, for high ambient environment Case Study Number TP3 Challenge The increasing flexibility of production lines requires a high adaptability of sensors.
