Which Is Neutral Refractory?


i. A refractory that is neither strongly basic nor strongly acid, such as chrome, mullite, or carbon. Ref: ARI. ii. A refractory that is resistant to chemical attack by both acid and basic slags, refractories, or fluxes at high temperatures.



Where are refractory bricks used?

Refractory brick is frequently used to construct kilns, furnaces and other high temperature enclosures. The refractory brick reduces heat loss and the chance of an unintended fire. The composition of the refractory brick will determine what temperatures it can withstand.


Which mineral is used as refractory material Mcq?

Explanation: Tungsten is a common refractory material which has the highest melting point of 3410oC among metals.


How is fire clay made?

Fire bricks or fire clay bricks are made from the fire clay. The process of manufacturing of these bricks is same as the ordinary bricks but are burnt at very high temperatures in a special type of kilns generally Hofmann's kill.

Question 34 : Which property of refractories is the most important for top section of the blast furnace? Resistance to abrasion.


What are the different types of refractories?

Depending on temperatures and service conditions of the applications such as boilers, furnaces, kilns, ovens etc, different types of refractories are used.

  • Fireclay refractories.
  • Silica brick.
  • High alumina refractories.
  • Magnesite refractories.
  • Chromite refractories.
  • Zirconia refractories.


Which of the following is refractory material?

Dolomite is a basic refractory material.

Silicon carbide is a special type of refractory material. They are used for special applications.


Which is neutral refractory?

i. A refractory that is neither strongly basic nor strongly acid, such as chrome, mullite, or carbon. Ref: ARI. ii. A refractory that is resistant to chemical attack by both acid and basic slags, refractories, or fluxes at high temperatures.


Which of the following is neutral refractory Mcq?

Chromite is neutral refractory material.


What is refractory brick made of?

Save this picture! For domestic uses, such as ovens, barbecue grills and fireplaces, the refractory bricks used are usually composed of clay containing mainly alumina and silica, elements capable of withstanding high temperatures. While alumina has reflective qualities, silica is an excellent insulator.


What is refractories and classification?

Refractories are classified according to their physical form. These are the shaped and unshaped refractories. The shaped is commonly known as refractory bricks and the unshaped as monolithic refractories. Shaped refractories are those which have fixed shapes when delivered to the user.


How do you find XC and XL?

This resultant is called REACTANCE; it is represented by the symbol X; and expressed by the equation X = XL − XC or X = XC − X L. Thus, if a circuit contains 50 ohms of inductive reactance and 25 ohms of capacitive reactance in series, the net reactance, or X, is 50 ohms − 25 ohms, or 25 ohms of inductive reactance.

What is the role of TCP IP Class 10?

It handles the address part of each packet so that the data is sent to the correct address. TCP stands for Transmission control protocol. It breaks message into smaller packets that are transmitted over the internet and also reassemble these smaller packets into the original message that are received from the internet.

Which of the following is an example of a combined variation?

Combined variation is a combination of direct, inverse, and joint variation. For example, the sales of a product may be directly proportional to the amount of money spent on advertising the product, but inversely proportional to the price of the product.


How did the science impact the society?

Science influences society through its knowledge and world view. Scientific knowledge and the procedures used by scientists influence the way many individuals in society think about themselves, others, and the environment. The effect of science on society is neither entirely beneficial nor entirely detrimental.


Are Korn Ferry tests timed?

Four main cognitive ability tests form part of the Korn Ferry test suite. Each of these tests is an adaptive test, and the tests are timed tests. The verbal reasoning test assesses a candidate's ability to read a text passage and then answer questions based on this.
