Multistandard Test System SM 4000

The system is designed to perform tests on iron raw material as ore pellets, lumps, sinter etc. according to several Standards. All Test procedures can be performed by same oven and same control system, equipped with proper gas flow meters and proper temperature programs.

Vertical oven is based on 5 separate heating zones with individual temperature control systems and is driven by means of solid state power units and temperature controllers and programmers.

Reaction tubes, made in high temperature alloys, include multiple thermocouples and gas inlet and outlet fittings, providing Standard test conditions.
The Oven can be equipped with a continuous weighing device showing and recording sample weight on digital display and logging unit.

SM 4000 features are:

Accuracy of test temperature during all reaction time
Isothermal temperature distribution in the sample
High accuracy of gases flow rate measurement and control
Accuracy of sample weight (resolution 0.1 g)

SM 4000 provides for automatic operation given by:

Automatic temperature time profile control
Gases input timing
Continuous monitoring of sample weight

    control panel

     

    Control panel includes complete top quality control and monitoring instrumentation. Temperature of sample is driven by digital programmer and by multiloop digital controller to obtain best isothermal test condition. A temperature alarm controller assures oven safety cutting off power in case of over temperature.

    Automatic inlet of Nitrogen reaction gas are provided according to temperature program. Gas flow control is obtained by digital mass flow meter for reaction gas and by a rotameter for N2 (as option a mass flow meter also for N2 is included).

    Manual gas control is also possible for checking purpose. Optional weighing system allows continuous monitoring of sample weight. A Touch screen recorder and data logger, and Ethernet connection, provide local and remote recording of test data.

    Vertical electric oven

    The electric oven consists of a steel structure placed on a frame and including the silica insulation material. Twenty silicon carbide high temperature heating rod elements are placed horizontally in a stack and are grouped in 5 heating zones to provide separate power control.

    Replacement of heating elements is fast and easy with no need of refractory maintenance so that oven life is very long. Inner high temperature chamber is protected by a quartz tube. The oven can be equipped, as an option, with a weighing system to provide continuous monitoring of sample weight during reduction test.

    Tumbler system TB 3000

    According to ISO 4696-1, ISO 4696-2, IS 10823 and IS 8167, the sample is tumbled after the reaction in the oven. Number of revolutions is pre-set on a digital counter showing remaining revolutions to the end of tumbling. Automatic stop at end of test is provided. The units are protected by a safety cage with switch on the door. Please refer to the Tumbler System product page for further information.
