INNOVATIONS IN LINING OF ALUMINUM-PROCESSING FURNACES

Close and fruitful cooperation between two companies lasts for nearly twenty-five years. DITHERM a.s. Praha, engaged in engineering, innovative designs and installations of refractory linings of thermal aggregates, and Průmyslová keramika Rájec-Jestřebí, a producer of predominantly non-shaped refractory masses and prefabricates made from these masses. A large number of quality linings have been created by this cooperation. Namely in the power generation industry (power and heating plant boilers firing a broad spectrum of fuels, waste incineration plants etc.), iron and non-ferrous metallurgy, chemical aggregates, etc. In the following article, we will focus on the development and installation of linings of tank smelting and holding furnaces for aluminum, in both design and material terms.

Company statement on the current situation

Dear business partners,

the exceptional situation, we all have to face now in relation to the situation around COVID-19, forces us to change our mind and activities. This is a global impact issue where we cannot predict its duration or economic and social impacts.

DITHERM a.s. celebrates 30 years on the market of the refractory linings in the Czech Republic and abroad.

We have grown up into a reliable, pro-active and innovative company. We are the leaders in high technical level, in application technologies, in material development and quick set up Your trust, cooperation and welfare are the biggest pleasure for us.

How CO (carbon monoxide) resistant are the linings?

For units that are used to the last moment of full functionality of the internal protective lining, we recommend thoroughly monitoring the amount of carbon monoxide, which is often underestimated.

Bursting – cracking, tearing, and chipping of the lining

Every technician managing a unit knows the phenomena listed below, which have a significant effect on the functionality of the internal lining of the unit. We decided to describe them professionally, and thereby point out their pitfalls for the operation of the unit.

How customers perceive us - they recommend us, want to co-operate with us, and welcome even more technical solutions

For us, every customer is not only a business partner, but also a very valuable source of feedback for many areas of our work. So this year we asked them for their opinion.

We ask the Purchasing and Management departments questions. Especially the Technical Experts of our clients.
