Alignment for Cut to Length: Positioning lasers
Operator from ECR has to verify that plates is in center for shear to work properly. Needed a good visible laser line on dark plates. Laser length up to 20mtrs. Z-laser designed the next generation green laser with high output power. Visible on dark surfaces with limited impact from ambient light conditions Home Case Studies Alignment for Cut to Length: Positioning lasers Alignment for Cut to Length: Positioning lasers 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 Higher production quality and throughput Positioning laser visible on plates/ sheet increasing operator efficiency Faster and more precise alignment of the shears, band saws and miter saws Laser length available upto 30mtrs depending upon mounting height Visible laser colour like green and red Laser mounted with help of precision mounting bracket Challenges Operator from ECR has to verify that plates is in center for shear to work properly Needed a good visible laser line on dark plates Laser length up to 20mtrs 24vdc supply and works in an industrial environment Green laser visible to the operator Solution Z-laser designed the next generation green laser with high output power Visible on dark surfaces with limited impact from ambient light conditions High IP protection class against dust and moisture Sturdiness to withstand impact and vibrations Accessories like precision mounting bracket and climate case Other application areas Red laser is continuously projected onto the Laser installed with installation height of 200 cutting edge of the saw so the production to max 1000mm to distribute the light homogenously engineer can align the workpiece with precision over the entire distance. Products and Accessories Positioning laser for visualization 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. 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.

Hot and Cold Rolling Mills / Main drives: Modernization of existing encoder installations
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 Hot and Cold Rolling Mills / Main drives: Modernization of existing encoder installations Hot and Cold Rolling Mills / Main drives: Modernization of existing encoder installations 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 Easy exchange or extension of existing encoder solutions Cost-efficient, as encoders can be exchanged selectively Implementation in the shortest possible time, optionally SIL certified Planning, delivery and mounting support from a single source Hübner Giessen standard encoder solution for main drives Task All around the world Hübner Giessen encoder solutions are installed at main drives of Hot and Cold Rolling Mills. These large motors often run for many years and after a while the question about a possible encoder modernization arises to provide new or additional electrical outputs. Solution With the encoder solutions implemented by us, the scope for a modernization is limited to a minimum. For example, our FGH 6 and FGH 8 encoders have an integrated mounting flange exworks. Thereby an additional encoder can easily be added to the existing encoder system. This could be a freely programmable overspeed switch or a universal encoder system with fiber optic signal transmission (both optionally SIL certified). But also an additional incrementalencoder with different pulse rate could be an option. In any case you can count on our support for the complete project.
