Melting processor

The melting processor is a system of hardware and software for controlling induction melting furnaces. It is suitable for retrofitting in existing furnace systems and offers the following advantages over manual furnace operation:

  • Reduction of energy demands
  • Increase in productivity by reducing non-productive time
  • Reproducible quality of the melt
  • Relief of the operating staff
  • Increase in operational reliability
  • Increased safety against overheating of the refractory lining
  • Documentation of operating data

The following operating modes can be realized with the melting processor:

  • Melting
  • Overheating
  • Holding
  • Cold start
  • Sintering
Charging system

A computer which is located e.g. in the control room and which carries out a constant data exchange with a possibly existing melting processor, the spectrometer, a central server in the company network, the crane scale as well as a text display and a platform scale each for the addition of aggregates and alloying elements is the core of the charging system.

The following illustration shows the block diagram of a typical system configuration.

The charging computer creates the recipes for the materials to be produced and compiles a sequence of recipes for a day‘s production. If desired, the recipe creation can also be carried out cost-optimized by the computer. The master data for the directional analyses and the input materials and aggregates form the basis for recipe creation. Optionally, the associated data (e.g. the percentages of the individual alloying elements) can be entered and managed on the computer itself or transferred from the server in the company network from any database system (SQL server, Oracle etc.).

Program for the creation of works test certifi cates according to EN 10204

The program is used for the comfortable creation of works test certifi cates according to EN 10204. It automatically imports the information required for creation, such as analysis data, mechanical properties, etc., from database fi les into which other programs such as the melting processor, charging system, tensile specimen evaluation program, etc. have been transferred.

Such files may be located on any computer within the company network

Program for the evaluation of tensile samples

The program for the evaluation of tensile specimens adopts the information on the force-extension diagrams stored in ASCII fi les by a tensile testing machine. They are displayed graphically and the yield strength Rp0.2 is determined. The data is stored in a database system and can be evaluated statically.

The following fi gure shows the main menu of the program:

The program offers the following functions:

  • Determination of the yield strength Rp0.2
  • Transfer of the data to a database system
  • Statistical analysis
