| Alexandr Beljajev: Application of Multivariable Control Systems for Universal Multizone Crystallizator |
This
paper presents some possible control algorithms for
regulation of crystal growth while it is growing via
directional solidification inside a multizone
crystallizator. The task of the process controller is to
establish a user-specified axial temperature profile and
to maintaint desirable solid-liquid interface's
parameters. Both single-input-single-output (SISO) and
multi-input-multi-output (MIMO) control algorithms have
been used to control the temperature. Comparison between
the resulting SISO an MIMO is performed. |
| Adrienn Nagy: Thermic recycling of plastic waste |
Recently,
utilisation or destruction or deposition of wastes, of
course, among the most important environment challenges
the plastic scrap is great social and technical one in
the World. Recycling of plastic scrap has an advantage
against the deposition or incineration because the
chemical energy of polymers and operation energy used for
their production involves a loss. Investigating this loss
we have found that it can be reduced by using a reduction
agent in a metallurgical Process (e.g.: in blast furnace)
or by converting to synthesis gas in a plasma furnace.
According to the thermodynamically calculation the chance
of arising the polychlorinated dioxins or furans has high
possibility but their concentration less than the
immission’s limit. |
| Krisztian Stoll: Research of the connection between the conformity of the product and the sample, with designed experimental method on metallurgical long products |
My field of
research connected with the quality, conformity,
qualification process and evaluation for conformity of
the products. At present we are specializing on the test
of the process of the evaluation for conformity and the
uncertainty of the rolled Boron steel product (ZF steel).
We have made experiments in order to find how the
differences between rolled and forged structures and the
position of sampling influence the values of tooth impact
test on toothed wheel. |
