Title: 6 Guidelines to Select Right Refractory for your Furnace.


1
6-Key Points to SelectRight Refractory
  • Refractory
  • Bricks and Castables

2
Why Right Refractory? What Experts Says?
  • Picking the right refractory will not only last
    longer, it also saves the Annual Fuel Cost.
  • It makes the Furnace more Efficient.
  • It saves a lot of Energy.
  • It minimizes the Shutdowns probability.

6-KeyPoints to Select the Right Refractory
  1. Type of Furnace Type of Fuel
  2. Mechanical Abrasion Impact
  3. Operating Temp. Service Limit
  4. Holding Weight at High Temp.
  5. Chemical Compatibility
  6. Max. Heat Conservation Min. Heat Loss

6-KeyPoints in Detail
1. Type of Furnace Fuel
  • The first thing to consider is Type of Furnace
    Type of Fuel. These 2 factors are the most
    imperative decision making key for selecting the
    right Refractory for furnaces/kilns/ovens.

2. Mechanical Abrasion Impact
  • A Refractory should be Strong Well bonded in
    order to withstand the Mechanical Abrasion and
    Impact.

3. Operating Temp. Service Limit
  • If the operating temperature of a
    Furnace/Kiln/Oven is more than the Refractorys
    Service Limit then it can cause a hazardous
    outcome for your project/product your valuable
    people.

6-KeyPoints in Detail
4. Holding Weight at High Temp.
  • The design of the furnace/kiln/ovens should be
    designed in such a way so that it can hold its
    own weight at high temperatures or else the whole
    structure will get collapsed.

5. Chemical Compatibility
  • The selection of the Refractory products should
    be based on the suitable specifications for a
    specific application. Using a wrong and
    unsuitable Refractory products may lead to
    dangerous failure in form of cracking or
    exploding.

5. Chemical Compatibility
  • There are various applications where refractories
    can be used, hence its a wise choice to select
    the right refractory for your requirement.
  • Slag Resistance completely rely on the chemical
    reactions between the refractory and slag.

5. Chemical Compatibility
  • There are 3 types of refractories with the
    following chemical compatibility
  • Acidic Refractory Acidic refractories are used
    for acidic slag condition as they reacts with
    basic materials.
  • Basic Refractory Basic refractories are used for
    basic slag condition as they reacts with acidic
    materials.
  • Neutral Refractory Neutral refractories may be
    used for all slag conditions.

6. Max. Heat Conservation Min. Heat Loss
  • It is always about the Maximum Heat
    Conservation Minimum Heat Loss which will
    help you to lower your Fuel Consumption and
    higher your Production.

6. Max. Heat Conservation Min. Heat Loss
  • The ultimate goal for selecting the right
    refractory for a specific application is to
    maximize and enhance the performance of the
    furnace/kiln/ovens.

6. Max. Heat Conservation Min. Heat Loss
  • It is not about the higher price will always be
    good, what matters is the most suitable
    refractory for your requirement.

6. Max. Heat Conservation Min. Heat Loss
  • When it comes to the Refractory Bricks,
    temperature gradient is the most worst enemy for
    them. Each brick should manage handle the
    stress due to temperature gradient and withstand
    the temperature fluctuations in their body. It
    should not crack or spall at any point of time.

15
Test Methods for Refractories
1. Pill Test
  • It is used when the quantities of Refractories
    are more than compare to quantities of Slag. The
    corrosion and spread of the molten mass is
    observed and calculated to find out the
    Refractory strength against Slag Attack.

Test Methods for Refractories
2. Immersion Method
  • This method is used when the quantities of
    Refractories are far less compare to quantities
    of Slag. A small piece of Refractory is placed in
    the Molten Slag.

Test Methods for Refractories
3. Fusion Test
  • In this test different quantities of refractory
    material and powdered slag has been used to find
    out the deformation of refractories which are in
    contact with slag.
  • So, by keeping all the above factors in mind,
    Furnace Manufacturers can easily select the right
    Refractories according to their requirement.
