Hightemp Furnaces Service Engineer Interview Questions, Process, and Tips

Heat treatment is used to improve the mechanical properties of industrial spares.

• Heat treatment involves heating and cooling a material to alter its properties.

• It can be used to increase hardness, strength, and durability of industrial spares.

• Examples of heat-treated industrial spares include gears, shafts, and springs.

• Different heat treatment methods include annealing, quenching, and tempering.

• Proper heat treatment ca...read more

Heat exchangers are used to transfer heat from one fluid to another fluid.

• Used in HVAC systems to regulate temperature

• Used in power plants to cool steam and increase efficiency

• Used in chemical processing to control temperature of reactions

• Used in refrigeration systems to cool air or liquids

• Used in food processing to pasteurize liquids or solids

Endothermic reaction is a chemical reaction that absorbs heat from the surroundings.

• Endothermic reactions require energy input to proceed.

• The reactants have lower energy than the products.

• Examples include photosynthesis, melting of ice, and evaporation of water.

• Endothermic reactions are opposite to exothermic reactions.

• Endothermic reactions are used in cold packs and instant ice packs.

Iron carbon diagram is a graphical representation of the phases of iron and carbon alloys.

• It shows the relationship between carbon content and the phases of iron

• It helps in understanding the properties of different types of steel

• It is used in the heat treatment of steel

• It is also known as the iron-carbon phase diagram

Temperature uniformity survey is a process of measuring and ensuring consistent temperature distribution in an environment.

• Temperature uniformity survey is important in industries such as pharmaceuticals, food processing, and electronics manufacturing.

• It involves measuring temperature at various points in a room or chamber and comparing the readings to ensure consistency.

• The survey helps identify areas where temperatur...read more
