The Functionality Of Hot Steel Rolling Mill Plant

Currently steel is one of the very efficient and greatly used materials that are produced over more than 1.3 billion tons every year. Steel is a primary component used in the manufacture of large automobiles, infrastructure, tools and appliances etc. Actually, steel is confined over its diverse custom-built features and functionalities. Steel before being utilized is processed and molded into specified form. These processes happen in steel rolling mill plants by using mill rolls.

Extensive Use of Mill Rolls


Mill rolls are meticulously designed tubular metal components used to feed and shape other metals. By putting one over another and counter rotating them they allow metal tubes, bars, sheets and wire to be fed through, shaping the product as it goes. Historically this form of machinery was utilized in steel mills to mold the forged steel into forms which can be sold for specific uses. These machines are presently utilized in light and heavy industrial processes. These range from the large scale processes of making parts for airplane and space vehicles to the, small scale making of jewellery. Notwithstanding the scale, a high level of precision is necessary.

Classification of Mill Rolls


The processes involving mill rolls are broadly classified into two categories - Hot Rolling and Cold Rolling. Hot rolling is typically used in the hot steel rolling mill plant at the initial stage of metal production, which mold heated metal into basic forms which eventually get used in cold rolling mills. Cold rolling lets the metal to be precisely formed into shapes which would later be used for specific tasks. Cold rolling mills are not only found in foundries but also used in other factories, in order to mold the metals into specific forms before it is made into an end product.

During the manufacture of mill rolls for use in the hot steel rolling mill plant, they have to conform to the precise specifications required by the process they will be utilized for. Among the tests that take place on mill rolls while they are manufactured, ultrasound is used to check for any defects which may exist in the rolls. Also, rigorous tests are done with regards to its tensile strength and hardness in order to ensure of the stresses they can withstand during operation.

Conclusion

Steel rolling mill machinery has proven its worth in a diverse range of industries.
