Submerged entry nozzles (SEN) are commonly used for slab cooling in continuous casting process.

• Submerged entry nozzles (SEN) are designed to deliver cooling water directly to the slab surface.

• SEN helps in controlling the solidification process and improving the quality of the slab.

• Examples of SEN manufacturers include Vesuvius, TATA Steel, and SMS group.

Internal casting defect in continuous casting refers to flaws or imperfections that occur within the casting material during the casting process.

• Internal shrinkage: caused by improper cooling or solidification of the casting material, leading to voids or cavities within the material.

• Inclusions: foreign particles or impurities that become trapped within the casting material, affecting its structural integrity.

• Segregatio...read more

External defects in continuous casting process include surface cracks, surface blowholes, and surface segregation.

• Surface cracks can occur due to improper cooling or excessive casting speed.

• Surface blowholes are caused by trapped gases in the molten metal.

• Surface segregation results from uneven distribution of alloying elements.

• Other external defects may include surface scabs and surface laps.

Miniscus level in continuous casting refers to the level of molten metal in the mold during the casting process.

• Miniscus level should be maintained at a specific height to ensure proper solidification of the metal.

• Maintaining the miniscus level helps control the flow of metal and prevent defects in the final product.

• If the miniscus level is too high, it can lead to overflow and if it is too low, it can cause issues wit...read more

Chromium is added to stainless steel to increase its corrosion resistance and strength.

• Chromium forms a passive oxide layer on the surface of stainless steel, which prevents rusting and corrosion.

• Chromium also improves the hardenability of stainless steel, making it stronger and more durable.

• The amount of chromium added to stainless steel can vary, with higher percentages leading to better corrosion resistance.

• For exam...read more
