Alfran offers specialized refractory solutions for the maintenance in lime furnaces, vertical cylinder or Maerz type. Our services include opening and closing inspection doors, scaffolding, demolition and cleaning, supply and installation of refractory materials.
We have a range of refractory castables, specially designed for lime furnaces, which can be installed by vibrocasting, such as ABR Clean + or by gunning, such as CAST 80 GL, in addition to our wide range of insulating castables.
We are available to our customers in the lime sector, to offer them, as we have done for more than 100 years, our Solutions in High Industrial Temperature.
The new global crisis originated by the Covid-19 has changed the world as we knew it. Now, the priority is to reduce the number of people involved in the installation process, to have enough distance between them, and to reduce the working time, to avoid risks of spreading the disease.
In this sense, Alfran recommends the best solution to install dense refractory castables: Alfranjet Shotcrete Technology. Alfran is #1 with Shotcrete Technology through its patented Alfranjet®, with more than 25 years of experience and worldwide references in Cement, Steel and Energy industries among others.
Why Alfranjet® Shotcrete?
- Reduced number of people. This highly improves safety operating conditions.
- High quality and performance. Accurate control of mixing liquid (WET PROCESS).
- High-speed installation: Average of 30 tons / 12h-shift.
- High efficiency & Energy Savings. < 10% losses.
The WRA (World Refractory Association) has uploaded a video explaining the importance of refractory materials in our day to day. It is a very illustrative video for those people who do not know the strategic aspects of this sector.
Did you know that our day to day life would be unimaginable if refractory products did not exist?
And, what are reafractory products?
Let’s take the example of a car: it is made with steel, copper, glass, aluminum and plastics, among others. These materials are manufactured at very high temperatures. For example, iron is melted in an oven and transformed into steel by processes that reach 2,000 °C. In order that the walls of the furnace are not affected by these temperatures, they have a coating of refractory material. In the same way, these coatings are also used for the manufacture of glass, copper, aluminum and plastics.
And how do you get refractory materials to withstand such high temperatures? What are they made of? And how are they manufactured?
It starts from diverse raw materials of alumina or magnesia base that are baked in special ovens up to 1,800ºC, and this process makes the refractory properties appear. The refractory material can be supplied as non-conformed or shaped.
How are these refractory materials used?
The refractory material is transported and installed in the facilities of our customers. For the installation, a specialized refractory company is required.
And, how long can these installed refractory materials withstand such high temperatures?
The life time of the coatings usually depends on the industry, since they work at different temperatures. In the steel industry, the material usually lasts from a few hours to a few weeks, while in the glass industry it can last up to 10 years.
Once the coating has worn out, it is removed and recycled when possible.
The refractory industry covers the entire cycle, from the extraction of raw materials, to recycling.

Alfran is a specialist in designing, supplying and installing refractories for aluminum melting furnaces.
We have a wide range of refractory castables, such as Tix-80 NW, Drytech 85 AL, Tix 55AL or Cast-60AL, among others, specially designed for the aluminium industry, as well as our insulating castables, Lite 10/14 and Lite 106. We carry out new construction or maintenance projects. On the other hand, another company of Grupo Aldomer, Intec-Heat is specialized in the drying of refractories, in this type of furnaces.
We are available to our customers in the aluminum industry, to offer them, as we have done for more than 100 years, our Solutions in High Industrial Temperature.
Within the power generation industry, Alfran offers detailed engineering solutions for refractory materials supply, installation and drying for biomass boilers.
From Alfran´s Technical, Operations and Sales Departments and with the support of another company of the Group, Intec-Heat, for the drying of the refractory, we provide turnkey solutions.
Our dense refractory castables, such as Tix 35 SiC or Cast 35 SiC, as well as the insulating refractory castable, Alfran Lite 10/14, are ideal for these biomass boilers.
We are available to our customers to offer, as we have done for over 100 years, our Industrial High Temperature Solutions.
