113 Slab detection: on the transfer table

Hot Rolling Mill, HRM

Slab detection: on the transfer table Smart Radar Sensor for width measurement Hot Rolling Mills Challenges High ambient environment: photocell is sandwiched between charged slab front and back side. Water cooling is not effective as thin capillary cooling tubes are used, which just cools the electronicspartially. Contamination in water cooling line can block the circulation of the water in sensor. Cooling circulation is only on the side surface, which is not an effective method. Burnt electronics:Choked circulation as the water is not clean Customer Benefit The high accuracy distance sensor with radar system- Contactless, inline measurement of slabs, strips, and plates (up to 1600 °C). Accuracy up to ±300 µm even in harsh environments Independent of alloy or metal type. Eliminates radiation hazards and reduces cost. Improved safety level as plant operators were not required to go in the high temperature zone to verify the water-cooling functionality. No housing and water cooling required.

Bearingless encoder system MAG withstands permanently extreme environmental conditions in the roll stand

Bearingless encoder system MAG withstands permanently extreme environmental conditions in the roll stand

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. Home Case Studies Bearingless encoder system MAG withstands permanently extreme environmental conditions in the roll stand Bearingless encoder system MAG withstands permanently extreme environmental conditions in the roll stand 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 Designed for high shock and vibration loads, aggressive cooling emulsions Tailor-made solution features an installation width of just 10 mm Special stainless-steel ring ensure a long service life Interference-free speed measurements of the metal strip for optimum drive control Sensors for strip speed measurement are exposed to extreme ambient conditions in the area of the measuring roll. Challenges The actual feedback value of the effective speed of the metal strip is required to effectively regulate the roll stand drives. It is possible to measure this value using suitable sensors located at the drive measuring roller between the stands. Shock and vibration loads as well as aggressive cooling emulsions mean the devices need to withstand extreme environmental conditions. In addition, limited installation space made it necessary to adapt the sensor system. Due to the loads mentioned above a measuring system installed to date was unable to supply interference-free speed signals. Tailor-made MAG system solution with extremely slim design and special Stainless steel bandage to protect the MAG pulse wheel. Solution Following discussions with the end customer Johannes Hübner Giessen installed a suitable measuring system with magnetic sensor technology that could be adapted to suit the conditions. The selected MAG 260 consists of a pulse wheel with an outside diameter of 260 mm as well as a scanning head with completely encapsulated electronics sealed to IP67. The bearingless system is unaffected by shock and vibration; it supplies interference-free signals even when exposed to extreme high quantities of aggressive liquids and vapours. Without using the reference pulse it was possible to implement the extremely slim 10 mm design width as needed.

Silicon Cable: 1800C to withstand temperature cycling causing cable cracking/ hardening Cable protection: Protect against cable damage from fire, scales, sparks, radiation heat Products and Accessories Hot rolling mill proximity with conduit Cable Protection conduits Case Study Number TP3 Challenge The increasing flexibility of production lines requires a high adaptability of sensors. Continually changing object geometries, different temperatures and very high radiation or surrounding temperatures are no rarity. In a pilger mill those rough conditions can be found, among others in the production of seemless steel pipes. The raw steel blocks, each weighing a few tons are heated up first in a round oven at a temperature of 1300 °C. After descaling of the surface, the steel block is prepunched in a hole press with a strength from a converted 2000 t. In the next sloping rolling mill the growing pipe rotates between two rollers that are positioned at an angle to each other. The punching is widened to the size of the mandrel diameter.

The signal of the infrared sensors controls the movement of centering device and abutment. The point of view is restricted by the tube and prevents disturbances by steam in the cooling phase. An optimum adaptation to the operating conditions is given due to the adjustable response temperature.

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.
