revestimieto refractario

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.

17 Apr: II Edition of Refractory Engineering Course

II Edition of Refractory Engineering Course

The National Association of Manufacturers of Refractory Products, Materials an Related Services (ANFRE) held in Seville, between March 11 and 14, the II Edition of Refractories Engineering Course.

It is a course taught by and for members of ANFRE that aims to train new generations of employees.

The course combines theoretical and practical training to obtain a global vision of the sector. In addition, the participants had the opportunity to visit both Siderúrgica Sevillana and our Alfran plant in Seville.

The following topics are found in the content of this course:

  • Refractory materials
  • Introduction to the design of coatings
  • Refractory application
  • Drying, heating and cooling
  • Safety and Quality Control

From Alfran, we want to thank the entire Association for the organization of these courses.

20 Feb: Campaign Protect yourself: Use of Personal Protective Equipment (PPE)

To combat the risks of accidents and damage to health, the application of technical and organizational measures is a priority. These measures are designed to eliminate risks at source or to protect workers through collective protection provisions.

Use of Personal Protective Equipment (PPE)

When these measures are not enough, the use of personal protective equipment (PPE) is imposed. The PPE act fundamentally reducing the consequences derived from the materialization of the risk. The protective efficacy will depend on the adequacy of the individual protection equipment at the pre-existing levels of risk.

The correct selection and use of the appropriate PPE will minimize the consequences and damages should the risk materialize. Therefore, the mandatory use of them is of vital importance.

 

 

Awareness campaigns in Alfran

With the aim of raising awareness among all employees towards active behavior in the prevention of occupational hazards and advancing their integration at all levels, different Awareness Campaigns will be carried out during 2019.

Casco Alfran

For this, maximum involvement and collaboration is necessary, highlighting the members of the Health and Safety Committee, Delegates and Prevention Technicians, Intermediate Managers and Project Managers.

The Management and Prevention Department request the involvement of all to achieve the proposed objectives.

16 Jan: The importance of refractory materials

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.
