How New Technology Applied In Refractories



As the basic material in the field of high-temperature technology, refractory materials are widely used in steel, non-ferrous metals, glass, cement, ceramics, petrochemical, machinery, boilers, light industry, electric power, military, and other fields. With the development of technology, the preparation technology of refractories is developing into the field of fine ceramics, and some special refractories are developed. At present, advanced preparation technology is also widely used in refractories. Then how is the new technology applied in refractories?

How Is the New Technology Applied in Refractories?



The following are the specific applications of nanotechnology, In situ synthesis, Self-propagating High-temperature Synthesis(SHS)and Functional Gradient Materials (FGM) technology in refractory materials.

NT (Nanotechnology)
The application of nanotechnology in refractories is mainly to introduce nanopowder into refractories. High purity corundum powder introduced into α-Al2O3 nanopowder and α-Al2O3 powder can promote solid-phase sintering and improve the sintering performance of the product.

In MgO-C composite refractory, the use of nano-carbon powder to replace flake graphite or to form nano-fiber in the original position of the matrix can significantly improve the performance of MgO-C refractory.

In Situ Synthesis
In situ synthesis technology refers to the generation of the second phase by the reaction to improve the properties of refractories, the advantage of which is that it can overcome the inherent defects of the second phase and reduce the price of the product. For example, SiC whiskers grown by in-situ synthesis technology can significantly enhance the strength and toughness of the Al2O3-C refractory.

Self-Propagating High-Temperature Synthesis (SHS)
With the development of self-propagating synthetic, it has been applied in the field of refractories. At present, the refractory materials prepared by the self-propagating synthesis techniques are used in the lining of aluminum smelting furnace with natural raw materials such as magnesite, dolomite, and chromite.

In addition, the SHS also has a certain application, and the process is to fill the appropriate reaction raw materials between the two refractories through SHS technology to make the intermediate raw materials react and then weld the two refractories.

Functional Gradient Material (FGM)
FGM is a new type of composite material developed to meet the need of repeated normal operation under the environment of super high temperature and large temperature drop. The remarkable feature of the material is that the components, structures, and physical properties of the material change continuously.

The FMG technology applied in the refractories is mainly based on the different parts of the refractory performance and structure requirements.

For example, a composite nozzle and multilayer lining materials are designed according to the thermal expansion characteristics between different materials and thermal stress problems.

However, the application of FGM in refractories should not only solve theoretical problems but also consider economic benefits.

Process Control Maintenance of refractory walls



Process control refractory walls and bricks.

Wherever the installation and/or maintenance of refractory systems demands specialised attention, Gouda Vuurvast Services' professionals are ready to provide the required expertise, reliability and quality. We do this 7 days a week, 24 hours a day. To deal with a problem, a project, a one-day job or planned maintenance based on a multi-year contract, our nationwide field service network ensures short lines of communication and a fast response.

Working together on solutions
Our specialists build, rebuild and maintain all kinds of refractory systems, whether it's a waste incineration plant, an oil cracking plant, a gasification plant or a furnace. Our expertise and attention are primarily focused on three industry groups: Non-Ferrous, Petrochemical and Environment & Energy. However, decades of experience have broadened our capabilities to any industrial segment in which refractory linings are used. As well as installation work, Gouda Vuurvast Services delivers added value by working together with customers on tailor-made solutions. Where the nature and scale of such projects make it necessary to do so, we work together on a project basis with third parties, for example to provide specialised engineering support. Our long-term relationships mean we know what customers need and we are familiar with their installations.

Maintenance
For Gouda Vuurvast Services, providing maintenance services means we are always on stand-by. This can be in accordance with a predefined schedule in case of structural process stops or planned preventive maintenance. As well as that, our strength is in corrective maintenance on a call-out basis. All work is carried out in accordance with detailed agreements. Our services can extend from opening a manhole for an inspection, if required followed by repair, right up to the complete replacement of a refractory lining.

In-house knowledge sourceRefractory materials are already subjected to a wide range of stringent demands, but combining these with customers' other operational requirements - for example in relation to wear resistance - often calls for technical compromises. Gouda Vuurvast Services' in-house laboratory serves as a source of advanced knowledge to our technologists in thinking of and developing effective tailor-made solutions.

Safety
Our customers can count on one hundred per cent attention to working safety. All practices are in accordance with the highest applicable standards, including the VCA (Safety Checklist for Contractors) requirements for the petrochemical industry. Gouda Vuurvast Services' strictly trained professionals earn this confidence through our exceptionally low scores in accident statistics.

Synergy
The organisational and physical proximity of other operating companies within the Refractories division enables Gouda Vuurvast Services to gain significant synergy benefits from the partnerships with associated companies such as Gouda Refractories. In each project, Gouda Vuurvast Services acts as the noticeable recognisable main contractor and is always directly accessible to the customer.
