Title: 6 Guidelines to Select Right Refractory for your Furnace.
16-Key Points to SelectRight Refractory
- Refractory
- Bricks and Castables
2Why 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.
36-KeyPoints to Select the Right Refractory
- Type of Furnace Type of Fuel
- Mechanical Abrasion Impact
- Operating Temp. Service Limit
- Holding Weight at High Temp.
- Chemical Compatibility
- Max. Heat Conservation Min. Heat Loss
46-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.

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.
15Test 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.
16Test 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.
17Test 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.
