Refractory Technology MCQ Practice Questions (Chemical Eng)

Course details

A refractory material or refractory is a heat resistant material: that is, a mineral that is resistant to decomposition by heat, pressure, or chemical attack, most commonly applied to a mineral that retains strength and form at high temperatures.

ASTM C71 defines refractories as "...non-metallic materials having those chemical and physical properties that make them applicable for structures, or as components of systems, that are exposed to environments above 1,000 F (811 K; 538 C)."

Refractory materials are used in furnaces, kilns, incinerators, and reactors.

Refractories are also used to make crucibles and moulds for casting glass and metals and for surfacing flame deflector systems for rocket launch structures. Today, the iron and steel-industry and metal casting sectors use approximately 70% of all refractories produced.

These questions will give you basic idea for Examinations Preparation and/or interview on Refractory Technology for Chemical Engineering.

Please Note:

1. These questions are only for practice and understanding level of knowledge only. It is not necessary that these questions may or may not appear for examinations and/or interview questions

2. In this practice test, because of large amount of questions (around 223 questions) some of questions may have repeated

3. I had to put as 70% pass rate because there may also be wrong answers from my side.
