Lifumat-M-model

tmax up to 0 °C

Remelting unit for sample preparation for spectroscopy (XRF, ICP, AAS, X-Emission) and scrap recycling, gas and vacuumtight. 3.3 - 30 kW

Applications:

casting, melting, remelting, sample preparation for spectroscopy

Most important characteristics

  • These casting machines are very versatile and capable of a wide range of melting applications from platinum to scrap iron within excellent reproducibility
  • Lifumat-M-6,6, -7,7, -Super and their vacuum versions are also suitable for production of calibration standards (cross sectional samples) and scrap (recycling) up to 2 kg
  • Spectroscopy sample preparation induction unit
  • The advantages of these model are minimal element losses, high sample throughput, ease of use and reliability
  • The high melting capacity with low energy consumption, reproducible operation through microprocessor control, ease of maintenance and a limited space requirement are the benchmark in this segment
  • High energy efficiency
  • Low weight
  • High quality – made in Germany
  • Easy to handle
  • Touch-Screen control and program-memory for highest user-friendliness

Technical details

The unit is used for preparation of metallic samples with uniform composition for emission and X-Ray spectrometric analysis, alloy development etc.

It consists of a 1,5 MHz fitted with noise suppression high-frequency respectively middle-frequency generator with an output power of 3,3 kW – 30 kW and being accommodated in a compact housing together with the induction remelting furnace working under atmosphere resp. vacuum or vacuum with protective gas, and centrifugal casting device with protective gas equipment. The space required is between 0,60 m² and 2,5 m².

Hardware / HMI

The operation is done over a colored touch panel 7” with 10 integrated function keys and integrated PLC function. Decentralized control blocks are used for the control of the machine functions. All inputs and outputs of the sensors and actuators are galvanically isolated and are protectively connected to MF/HF with the decentralized control unit. Process data and process parameters can be read out over an USB interface. An emergency switch, which is well accessible, gives additional safety during operation.  

Scope of functions

Simple user operation through self-explanatory menu navigation and navigated program flows. Optical visualization of program flow of the respective work steps, program inform over the current status of the machine. Integrated recipe administration for melting programs. Compiled melting programs can be saved easily on a USB stick and implement in further machines of the same types, without having to compile it new.

Safety supervision from various functions with clear text and acoustic alarm emission, for example cooling water temperature, cooling water flow, cover and door locking, generator current (power).

Optical and acoustic signalization in case of failures and at the end of the casting process. Recording of all alarms and faults with date and time stamp.

Safety switch: Magnetic cover locking during casting process, as well as automatic power switch-off when opening the cover during the melting process

Program functions: Atmosphere, vacuum or pre-vacuum with subsequent protective gas flushing up to max. 0,4 bar over pressure (upon request up to 2 bar against surcharge). 

User language selectable (German, English, Russian, Chinese = standard, others on request against surcharge).

User level locked interface (manufacturer, administrator, operator)

Hand mode

Free adjustable process parameters in order to optimize processes and compiled melting programs.

Status display of hardware inputs and outputs. 

Optional, on request:

  • Optional process data acquisition of generator power and melting temperature
  • Ethernet interface for integration in a customer network.
