New
Technology R&D Center is mainly engaged in research, development
and dissemination of new foundry technology, materials, processes
and engineering design, The following sections are affiliated
to the new technology research and development center of the
institute: the research section of advanced engineering
materials, the research section of gravity
die casting technology, the research section
of advanced melting equipment and comprehensive
laboratory section.
The research section of advanced engineering materials
carries out research, development and application work of new
materials and technology in the field of nuclear engineering.
The newly developed martensitic stainless steel, magnetic ductile
iron, low carbon and super-low alloy cast steel, nickel austenitic
corrosion resistant cast iron and boron cast steel have been
successfully used in industry and national key military projects,
such as: driving mechanism for control rods, support of the
main equipment, water filter mechanism, etc—used for the Qinshan
(2nd period) nuclear power station. Now the property optimizing
work of new boron cast steel (shielding material) and research
and development of high effective shielding materials are being
made.
The research section of advanced casting febricating
technology carries out researh and development of low
presure casting, permenant mould casting, expendable pattern
casting (EPC), etc., all of advanced shape casting febricating
techgnologies and applying them in industries. A developed low
pressure casting technology for pressure-resisting copper casting
has been applied to febricate some of key parts and components
for national important enginnering project. Permenant mould
casting technology has been applied to febricate in large amount
of castings for automobile. Right now a low pressure cast technology
is developing for large sized casting of copper alloys, meanwhile
the research section is engaged in research, development and
application of wear resisting cast iron、corrosion resising
cast iron and heat resisting cast iron as well as ductile cast
iron with high properties.
The research section of advanced die casting technology
carries out research and development of computer application
in foundry field. The section has successfully developed the
numerical simulation software-SRIF Cast, ESRC Cast, Casting
Technology CAD, etc. The commercial software developed by the
section can be used for numerical simulation, calculation of
sand mold casting, gravity die casting, investment casting,
electroslag remelt casting, etc. to simulate the processes,
to analyze procedure quality and to optimize technology.
The research section of refining equipment
carries out research and development of AOD steel refining equipment.
Whole AOD equipment and employee training can be carried out
by SRIF.
In the comprehensive laboratory section,
there are some equipments for smelting, heat treatment ,etc.
which serve as the means of research and development of new
technology, materials and processes.
It provides technology and devices for casting
simulation, proccess design, output of product and process drawings,
etc. |

AOD Steel Refining Equipment
|
|
Characteristic
of process and equipment of AOD
AOD (Argon
Oxygen Decarburization) is a process for refining ultra-low carbon stainless
steel and cleaning alloy steel. In this process, the molten steel is
achieved with ultra-low content of carbon(C<0.01) and sulfur(S<0.003),
high degree of cleaning and low content of gas. The steels and castings
have desirable mechanical Property.
·The composition of stainless steel should be precisely controlled.
·Making use of the cheap raw material , the cost of produce is reduced.
·Comparing with the only process of EAF, productive efficiency of AOD
is highly improved.
Content of
AOD refining system
·The AOD Vessel system
·The control system (including intelligent control system)
·The valve rack system
·AOD system software and proprietary technology, technology training
and installation of AOD system.
·Supplying the design parameter and technology requirement of gas workstation,
fume extraction system, Sampling and De-slagging Platform and Vessel
Preheater etc.
