Rolling Mills / Screw Downs: Replacing Mechanical Cam Limit Switches at the Screw Downs (Rolling Mill) Increases Precision and Lowers Costs
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 Rolling Mill / Rolling Mills / Screw Downs: Replacing Mechanical Cam Limit Switches at the Screw Downs (Rolling Mill) Increases Precision and Lowers Costs Rolling Mills / Screw Downs: Replacing Mechanical Cam Limit Switches at the Screw Downs (Rolling Mill) Increases Precision and Lowers Costs 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 Simple programming & presetting Additional real-time position data (4 – 20 mA) Direct attachment without distribution gears Before: Distribution gears and mechanical position switch Challenges The customer wanted a 1:1 replacement of the existing mechanical solution. There were several reasons behind this: Higher precision required Spare parts no longer available Reduce costs by stocking less spare parts Additional current output for real-time position data After: Directly attached electronic position switch ERC 40 with an additional current output for up-to-date position monitoring. Solution Setting the switching points was difficult with the obsolete mechanical solution. This is much simpler with the ERC 40. It enables the customer to move the screw downs to the desired position for a switching point – and then transmit the information to the software by drag & drop. As the data is stored in the ERC 40 and can be stored on the PC the customer is able to simply copy previously set switching points as required to further devices. Storing the reference position and preset configuration makes it possible to reference the ERC 40 along with the application, for instance after changing rolls. Eliminating the need for distribution gears combined with the higher precision of the ERC 40 has significantly increased the accuracy of the whole system. The current output (4 – 20 mA) of the ERC 40 also supplies additional real-time position data.

Temperature Monitoring of the Pusher Arm Wall using Ratio Pyrometer
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). Ratio Technology 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. Customer Benefit Increased quality: High quality metallurgical coke improves iron and steel making process. High Coke Yield: Critical for good quality coke, the oven and heating chambers in coke oven battery are controlled. Environmental conditions Hot Strip Mill: Presence of steam, dust, dirt, clogged viewports Bar Mill: Small diameter of bar that keeps fluttering Hot metal casting or pouring: When target emissivity are low or changing by the same factor in both wavelength bands. Installation Challenge In high ambient temperature, water cooling is required and sensor is installed far away thus reducing the impact of IR energy received by the sensor. Advantages Able to look through dust and dirt and steam. Only 5% FOV to be covered for accurate temperature. Emissivity has less effect on Temperature measurement. Optical sensor head can withstand 200°C (315°C on special request) without water cooling. As the sensor can be mounted closer to the hot object thus improving the preciseness in temperature measurement.

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. Previous solution / Competitor product N/A Solution The sensor that was installed at this application is the HMD OKA 2038.38 G with tube OL 19. 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. The HMD with self-learning response temperature (Auto-Teach function) is suited to continually changing conditions. The compact sensor with a stainless steel housing can withstand surrounding temperatures of up to 75° C. The use of a cooling jacket raises this up to 200° C. Alternatively sensors with fibre optic cables are available which permit an application at ambient temperatures up to 600° C without cooling. Customer Benefits Maintenance-free High temperature stability Recognition of hot objects at big distances Self adjustment with Auto-Teach or step switch for the response temperature Product Part number OKA 2038.38 G Brand Proxitron Accessories Piros swivel stand HM2 Tube OL 19 Pilot light unit (for alignment) DAK 308 + OL 26 Different cable lengths (e.g. 15 m) Customer Testimonial compared to previous solution or competition Case Studies Other Solutions in R&D Sample case study title lorem ipsum here Short description of the problem solved, maybe include the client name.
