Selbstverständlich können Sie aus unserer Giesserei direkt Rundbarren beziehen. Die Rundbarren werden konventionell im Stranggussverfahren mit Schwimmer-Düse-Technik gegossen. Die anschließende Homogenisierung erfolgt in unseren Kammeröfen. Wir bieten Ihnen kurzfristig und in kleineren Mengen abgedrehte Rundbarren an. Neben dem breiten Abmessungs- und Legierungsspektrum stehen Ihre Wünsche im Vordergrund. Gemeinsam finden wir sicher auch für Ihre Legierungsspezifikation eine Liefermöglichkeit.

Particular Challenges of the Application: By tactile equipment, determination of the deepest point on a rough metal surface is neither simple or precise. As a consequence, often either too much material is removed, or the surface is still covered with defects which have to be eliminated by a following milling cycle. The equipment is arranged in parallel, so that the complete width of the slabs is covered. The sensors are calibrated to a common coordinate system and mounted on a movable gantry. Before measurement, the slabs are fixed in place. The scanners mounted on the gantry are guided over the measuring object, driven by an electric motor. The point cloud recorded by the four scanners is consolidated in a PC by means of the QuellTech image processing software which calculates the difference between highest and lowest point of the corresponding surface and compensates for possible inclination of the slab (detrending).

To produce industrial aluminum of this caliber, Novelis begins by carefully controlling the composition of the alloy, then taking exceptional care in the casting procedure to avoid non-metallic impurities. The surfaces of the aluminum ingots are then sawed and scalped to remove any new impurities before rolling. These ingots are preheated for long periods for optimal homogenization of the metal structure, then hot- and cold-rolling procedures achieve high surface quality. “Bright rolling” delivers the highest possible surface consistency and reflectivity. The result is an aluminum surface reflective enough to be used as a mirror.

SiBrickScan (SBS) is a dedicated at-line system for the FTIR quantification of interstitial Oxygen in complete Silicon ingots, resulting in a concentration profile along the longitudinal axis. Accessing this information without sawing wafers or test samples is a major and cost saving advantage. Get Valuable Information to Check and Optimize Product Quality Knowing the Oxygen gradient of Si ingots enables important conclusions helping e.g. to control and optimize the Silicon crystallization process or to identify batches of bad raw material. Therefore SBS will help to save costs by optimizing product quality and reducing the amount of defective wafers. The random sampling of individual ingots does strongly reduce sample preparation efforts and provides relevant information much earlier.

QuellTech Solution: The performance of a manual inspection cannot be compared with the speed and the repeatability of a contactless QuellTech Q4-1000 laser scanner. It is even possible to install several instruments in parallel to cover the whole width of the ingot with one single scan. These instruments are mounted on an existing portal and correctly synchronized, so that interaction of the laser light originating from the other scanners is excluded. The QuellTech laser line scanners produce 3D point cloud of the raw ingot surface, and the software calculates the coordinates of the highest and deepest levels of this surface. After scalping the flat surface can be scanned again for any defects. Benefits for the Client: Thanks to QuellTech’s wide area laser line scanners, the cycle times for ingot scalping could considerably be reduced, and excessive material scrap due to a too low scalping level is prevented.
