JSW Steel Senior QA QC Engineer Interview Questions and Answers

Steel is an alloy of iron and carbon, with other elements added to enhance its properties.

• Steel is primarily composed of iron and carbon.

• The carbon content in steel is typically between 0.2% and 2.1%.

• Other elements like manganese, chromium, nickel, and molybdenum are added to improve strength, hardness, and corrosion resistance.

• The composition of steel can vary depending on the desired properties and intended use.

• For e...read more

The melting point of steel varies depending on the type of steel, but generally ranges from 1370-1530°C (2500-2790°F).

• Steel is an alloy of iron and carbon, with other elements added for specific properties.

• The melting point of steel can be affected by the amount and type of alloying elements.

• Different types of steel have different melting points, with some high-strength steels having melting points above 2000°C.

• Steel c...read more

Blast furnace liquids refer to the molten iron and slag that are produced during the iron-making process in a blast furnace.

• Blast furnace liquids are a mixture of molten iron and slag

• They are produced during the iron-making process in a blast furnace

• The molten iron is typically used to make steel

• The slag is a byproduct that can be used in construction or as a raw material in cement production

Slag is a byproduct of metal smelting process. Flux is a substance used to promote fusion in welding and soldering.

• Slag is a glass-like byproduct of metal smelting process

• It is usually composed of impurities that are separated from the metal during the smelting process

• Flux is a substance used to promote fusion in welding and soldering

• It helps to prevent oxidation and other impurities from contaminating the weld or sold...read more

Ladle refining process is a secondary steelmaking process used to remove impurities from molten steel.

• Molten steel is transferred from the primary steelmaking furnace to a ladle.

• Various chemicals are added to the ladle to remove impurities such as sulfur, phosphorus, and carbon.

• The ladle is then stirred to ensure the chemicals are evenly distributed.

• The refined steel is then poured into molds to create the desired shap...read more
