COLD ROLLING MILLS – Furnace
From steel and paper to plastic films, we have installed thousands of standard and customized force and web tension systems. BLH Nobel designs force measurement modules according to the customer’s mechanical requirements and forces, ranging in size from just a few Newton to mega-Newtons.
BLH Nobel’s PST Web Tension Measuring Units are used for steel strip in galvanizing or hardening/annealing furnace. It allows a great thermal expansion of roller and can measure the exact resulting force of the strip tension.
Accurate Measurement of Strip Tension
BLH Nobel’s PST force measurement unit are specially designed for the process line furnaces. The specifications are the same as for BLH’s FMU measuring units in the process lines but with the ability to absorb very high axial forces from the thermally expanded furnace rollers without affecting the measurement precision, even in low measuring ranges. This is unique in the market. There are also EX approved versions.
Internally Compensated Setup
Thermal expansion of the roller induce large axial force and moment that is not to be measured by the force-measuring unit. BLH Nobel’s PST force measurement blocks can easily compensate for by the unique capabilities of our built-in KIS load cells and the symmetric positioning of four KIS units, relative to the bearing application point.
No need of extra bearings to accommodate the expansion. Only the strip tension is measured and transmitted to the control system.
BLH provides the unique PST force measurement block together with junction box and a complete range of transmitters with many supported fieldbuses. Moreover, BLH can supply all types of cabinets (size, material, color etc.) to house the instrumentation and we support on-site calibration services worldwide.
Unique KIS Load Cell:
The KIS load cell is capable to withstand dynamic forces, high lateral forces, shear stress and bending effect. Its smart features make it resistant to high overload forces no matter the direction. This unique construction makes the scale stronger, more accurate and globally less expensive than the standard U shape one. Thanks to the smart design of our KIS 1 load cells, complicated mechanical arrangements such as rods are avoided in the coil weighing system. BLH Nobel can provide OIML applications with KIS 11 load cell and our unique G5 PM with OIML R76 approval
