10+ JSW Steel Assistant Engineer Interview Questions and Answers

Special precautions during mold filling in rainy season

• Ensure proper drainage system to avoid water accumulation

• Cover the mold to prevent rainwater from entering

• Increase mold temperature to compensate for high humidity

• Use mold release agents to prevent water from sticking to the mold surface

• Inspect mold for any signs of water damage before and after filling

A diode is an electronic component that allows current to flow in one direction only.

• Diodes are commonly used to convert AC to DC in power supplies.

• They are also used to protect circuits from reverse polarity.

• Diodes have a forward voltage drop, typically around 0.7V.

• They can be used in rectifier circuits to convert AC to DC.

• Diodes are also used in signal processing circuits to separate AC and DC components.

LOTO, WAH, and material handling are important safety procedures in engineering.

• LOTO stands for Lockout/Tagout and is a safety procedure used to ensure that dangerous machines are properly shut off and not started up again before maintenance or repair work is completed.

• WAH stands for Work at Height and refers to safety procedures used when working at elevated heights, such as on scaffolding or ladders.

• Material handling refers to the safe movement, storage, and control of mate...read more

Circuit breakers are electrical switches designed to protect electrical circuits from damage caused by overload or short circuit.

• Circuit breakers automatically interrupt the flow of electricity when a fault is detected.

• They can be reset manually after tripping to restore power.

• Common types include thermal-magnetic, magnetic, and hydraulic-magnetic circuit breakers.

• Examples include miniature circuit breakers (MCBs) and molded case circuit breakers (MCCBs).

AC and DC are two types of electrical current with different characteristics.

• AC stands for alternating current, which periodically changes direction.

• DC stands for direct current, which flows in one direction.

• AC is commonly used in household appliances and power distribution systems.

• DC is commonly used in batteries and electronic devices.

• AC can be easily converted to different voltage levels using transformers.

• DC is more efficient for long-distance transmission of electricity....read more

LT stands for Low Tension and HT stands for High Tension. They refer to different voltage levels used in electrical systems.

• LT refers to voltage levels below 1000V, while HT refers to voltage levels above 1000V.

• LT is commonly used in residential and small commercial buildings, while HT is used in industrial and large commercial buildings.

• LT systems are generally safer and easier to maintain compared to HT systems.

• Examples of LT equipment include household appliances, while ex...read more

Types of maintenance include corrective, preventive, predictive, and proactive maintenance.

• Corrective maintenance involves fixing a problem after it has occurred.

• Preventive maintenance involves regularly scheduled maintenance to prevent problems from occurring.

• Predictive maintenance involves using data and analytics to predict when maintenance is needed.

• Proactive maintenance involves identifying and addressing potential issues before they become problems.

• Examples include chan...read more

Utility maintenance equipment includes tools and machinery used to maintain utilities like water, electricity, and HVAC systems.

• Regular inspection and maintenance of utility equipment is essential to ensure proper functioning

• Common utility maintenance equipment includes voltage testers, pipe wrenches, multimeters, and pressure gauges

• Proper training on how to use and maintain utility equipment is crucial to prevent accidents and ensure efficiency

Iron-Carbide diagram is a graphical representation of the phases present in an iron-carbon alloy at different temperatures.

• Shows the phases of iron and carbon at different temperatures

• Helps in understanding the microstructure of steel

• Consists of regions like austenite, ferrite, cementite, and pearlite
