Metallurgical Engineering Intern Interview Questions and Answers

There are three main stages in a blast furnace: preheating, reduction, and refining.

• Preheating stage involves heating the furnace and charging it with raw materials like iron ore, coke, and limestone.

• Reduction stage involves the conversion of iron ore into molten iron by removing oxygen through a chemical reaction with carbon monoxide.

• Refining stage involves further processing the molten iron to remove impurities and adjust the composition to desired levels.

• Each stage is cruc...read more

Blast furnace charging involves loading raw materials like iron ore, coke, and limestone into the furnace for smelting.

• Raw materials such as iron ore, coke, and limestone are loaded into the blast furnace through the top using skip cars or conveyor belts.

• The materials are carefully layered to ensure proper distribution and efficient melting.

• The charging process is crucial for maintaining the proper chemical reactions and temperature inside the furnace.

• The raw materials underg...read more

Touch cutting machines work by using a touch screen interface to control the cutting process.

• Touch cutting machines are operated using a touch screen interface for easy control and precision.

• Operators can input cutting parameters such as speed, depth, and direction through the touch screen.

• The machine then uses this input to accurately cut materials such as metal, plastic, or wood.

• Touch cutting machines are commonly used in industries like manufacturing, automotive, and aeros...read more
