Steel Manufacturing Process Quiz

A material added to the Electric Arc Furnace during steel melting to control the carbon content in the steel.

A material used to make a slag in the Electric Arc Furnace during steel melting.

A material used in steelmaking to achieve the desired silicon content in the steel, particularly for casting railway steel wheels.

A finely powdered material used in wet magnetic particle inspection to highlight surface and subsurface defects in cast steel railway wheels.

A material added to the electric arc furnace during steelmaking to achieve the desired manganese and silicon content in the steel, especially for casting railway steel wheels.

A material used as a furnace addition in the electric arc furnace during steelmaking for casting railway steel wheels.

A powder used to create a spray for graphite molds, ensuring a smooth and stable mold surface during casting.

A material added to the liquid steel tapped from the Electric Arc Furnace to adjust the silicon content for the desired final composition, often for railway steel wheels.

A process where a material is added directly into the electric arc furnace during steel production.

A process where a material is added after the steel has been tapped from the electric arc furnace, usually in a ladle.

Steel shots are used to clean and smooth the surface of cast steel wheels, a process known as shot peening.

The hardness of cast steel wheels is measured using the Brinell Hardness Number (BHN). Wheels used in this process have a hardness range of 255 to 363 BHN.

The average number of wheels cast per day is a measure of production output.

The number of "good wheels" produced per day is a measure of quality and efficiency. This number is lower than the total number of wheels cast due to imperfections or rejections.

Wheel rejection percentage is the percentage of wheels that did not meet quality standards and had to be discarded.

The average number of heats per day is a measure of the frequency of metal melting and casting operations.

The data presented refers to the period between the years 2013 and 2016.

In the 2013-2014 period, the average number of wheels cast per day was 704. In 2014-2015, it was 641, and in 2015-2016, it was 680.

In the 2013-2014 period, the average number of heats per day was 22.75. In 2014-2015, it was 22.62, and in 2015-2016, it was 20.79.

The rejection rate fluctuated between 5.93% and 7.51%, indicating variation in production quality.

A material used to seal between the mold and the pouring tube during the casting of steel wheels, stopping the molten steel from leaking.

A sleeve made from a mixture of clay and graphite, used as a conduit for molten steel to flow into the mold.

A process where the ingate sleeve is heated in a controlled environment to eliminate moisture and ensure its integrity.

A tube made of ceramic, used to direct the flow of molten steel from the pouring tank to the mold.

A coating applied to the pouring tube, filling the pores and making it air-tight.

A stopper made from a mix of clay and graphite, positioned inside the mold after pouring to prevent the molten metal from flowing back.

The method of pouring molten metal into the mold using controlled pressure to ensure consistent and accurate filling.

The process of removing any excess material from the ingate after each casting using a grinding stone, ensuring a smooth and accurate fit for the stopper.

The metal used directly in the manufacture of the wheel, such as coke, graphite, ferromanganese, etc.

Materials used indirectly to support the wheel manufacturing process, like asbestos gasket or ingate sleeves.
