Sintering Furnace for Cobalt-Chromium


LT 02/13 CR | Sintering Furnace for Cobalt-Chromium


The sintering furnace LT 02/13 CR is perfectly suited for sintering of cobalt-chromium restorations. The milt objects are placed in a special sintering tray and will be sinterd under argon. The specific design in combination with sintering pearls provides for good sintering results in a nearly oxygen-free atmosphere at very low argon consumption.

The system is open and can be programmed for various materials up to sintering temperatures of 1300 °C. Two pre-installed sample programs, which can be adjusted individually. Furthermore, the sintering furnace LT 02/13 CR is designed for a single-phase connection.

**Process Control and Documentation C450 Controller

Data Storing of Nabertherm Controllers with NTLog Basic

The Controller C450 is equipped with a USB interface as standard, which allows data recording via the NTLog Basic. The process data is recorded with a client-side USB-stick which is inserted during the process. The process documentation with NTLog Basic requires no additional thermocouples or sensors. Only data recorded which are available in the controller. The data stored on the USB stick (up to 80,000 data records, format CSV) can afterwards be evaluated on the PC either via NTGraph or a spreadsheet software used by the customer (e.g. MS Excel). For protection against data manipulation the generated data records contain checksums.

Visualization with NTGraph
The process data from NTLog can be visualized either using the customer‘s own spreadsheet program (e.g. MS‑Excel) or NTGraph (Freeware). With NTGraph Nabertherm provides for a user-friendly tool free of charge for the visualization of the data generated by NTLog. Prerequisite for its use is the installation of the program MS Excel for Windows (version 2003/2010/2013). After data import presentation as diagram, table or report can be chosen. The design (color, scaling, reference labels) can be adapted by using prepared sets. NTGraph is available in seven languages (DE/EN/FR/SP/IT/CH/RU). In addition, selected texts can be generated in other languages.

VCD-Software for Visualization, Control and Documentation
Documentation and reproducibility are more and more important for quality assurance. The powerful VCD software represents an optimal solution for single multi furnace systems as well as charg documentation on the basis of Nabertherm controllers. The VCD software is used to record process data from the Controller C450. Up to 400 different heat treatment programs can be stored. The controllers are started and stopped via the software. The process is documented and archived accordingly. The data display can can be carried-out in a diagram or as data table. Even a transfer of process data to MS Excel (.csv format *) or the generation of reports in PDF format is possible.
