JSW Steel Interview Questions, Process, and Tips

PLC CPU model refers to the central processing unit of a programmable logic controller.

• PLC CPU model is the main component of a PLC responsible for executing logic and controlling processes.

• Examples of PLC CPU models include Siemens S7-1200, Allen-Bradley ControlLogix, and Mitsubishi FX Series.

• The CPU model determines the processing speed, memory capacity, and communication capabilities of the PLC.

Scintillation counter components are used to detect and measure ionizing radiation by converting the energy of incoming particles into flashes of light.

• Consists of a scintillator material that emits light when struck by ionizing radiation

• Includes a photomultiplier tube to convert the light into an electrical signal

• May also have electronic components for signal processing and data analysis

Procurement steps involve identifying needs, selecting suppliers, negotiating contracts, and managing supplier relationships.

• Identify needs and requirements

• Research potential suppliers

• Request for proposals or quotes

• Negotiate terms and pricing

• Select supplier

• Create and sign contracts

• Manage supplier relationships

Reverse auction is a type of auction in which sellers compete to obtain business from a buyer by offering lower prices.

• Buyers post their requirements and sellers bid with lower prices to win the business.

• The seller with the lowest bid at the end of the auction wins the contract.

• Reverse auctions are commonly used in procurement processes to drive down prices.

• Examples include online platforms like Ariba and Procurify.

I have handled categories such as marketing, sales, operations, and finance in my previous roles.

• Marketing

• Sales

• Operations

• Finance

Iron steel rods are used in construction for their strength, durability, and flexibility.

• Provide structural support in buildings and bridges

• Resist tension and compression forces

• Can be easily bent and shaped to fit specific construction needs

• Help reinforce concrete structures to prevent cracking

• Durable and long-lasting material for construction projects

M25 ratio is the mix design ratio of concrete which represents the ratio of cement, sand, and aggregate in the concrete mix.

• M25 ratio is commonly used in construction for structural concrete.

• It represents the mix design ratio of 1:1:2, which means 1 part cement, 1 part sand, and 2 parts aggregate.

• The strength of concrete produced using M25 ratio is typically around 25 megapascals (MPa) after 28 days of curing.

The 50mt structure gallery can be erected using cranes, scaffolding, and skilled labor.

• Use cranes to lift and place heavy components of the structure.

• Set up scaffolding for workers to access different levels of the structure.

• Ensure skilled laborers follow safety protocols and construction plans.

• Use appropriate tools and equipment for assembly and welding.

• Inspect the structure regularly for quality control and safety me

Ohm

• Unit of resistance in electrical circuits

• Symbol is Ω (omega)

• Named after German physicist Georg Simon Ohm

• Measured using an ohmmeter

The unit of current is Ampere (A)

• The unit of current is Ampere (A)

• Current is the flow of electric charge in a circuit

• 1 Ampere is equal to 1 Coulomb per second

• Commonly used prefixes for current are milliampere (mA) and microampere (μA)
