Product descriptionPickled Hot-rolled steel is a steel product obtained through hot rolling and subsequent acid pickling to remove surface oxides, providing a clean and uniform finish
Product information from external sourceshttps://tyasa.com/
Technical purpose of productPickled Hot-rolled steel is a steel product obtained through hot rolling and subsequent acid pickling to remove surface oxides, providing a clean and uniform finish.
Manufacturing or service provision descriptionThe production of Pickled Hot-rolled steel at TYASA follows a carefully integrated process that begins with the reception, sorting, and preheating of scrap, which is later melted in a Quantum electric arc furnace using both electricity and natural gas. After the addition of ferroalloys, refining, and vacuum degassing, the molten steel is cast through the CASTRIP® system into thin sheets, which are then rolled to the required thickness, cooled and coiled. The coils undergo cold finishing operations, including stress leveling to eliminate internal tensions. Finally, the steel passes through a pickling process, where oxides, scale, and surface contaminants such as grease and oils are removed by highpressure metallic abrasives. This treatment provides the steel with a clean, uniform surface, free of imperfections, which enhances its quality and makes it suitable for further industrial applications. The result is a Pickled hot-rolled steel.

Technology description including background systemPickled hot-rolled steel manufactured by TYASA is produced using steel scrap as the main raw material. The process includes scrap reception and preparation, melting in a Quantum electric arc furnace using electricity and natural gas, alloying, refining, and vacuum degassing, followed by casting through the CASTRIP® process, hot rolling, cooling, and coiling. Cold finishing operations such as tension leveling may be applied. An acid pickling process is used to remove surface oxides and surface contaminants.

Data quality assessment

Description of data quality assessment and reference yearsDirect data obtained from T A 2000 S.A. de C.V. is representative for 2022. According to ISO 14044, data validity verified during the collection process to provide evidence that the quality criteria required for the intended application are met. The data quality level and criteria used were based on the Product Category Rules (GPI 5.0.1, section A.5.4), the EN 15804:2012+A2:2019/AC:2021 standard (Annex E), and the PCR Construction Products v2.0.1, section 4.6.5.Data quality assessment was carried out using the following quality levels: very good, good, fair, poor, and very poor.
