Talleres y Aceros S.A. de C.V. (Tyasa), a Mexican steel producer, issued Primetals Technologies with the final acceptance certificate for a new mini-mill meltshop. The plant was constructed on the Ixtaczoquitlan site and has an annual capacity of 1.2 million metric tons of steel. Primetals Technologies supplied a Quantum electric-arc furnace, which has a tapping weight of 100 metric tons and cuts the specific conversion costs of electric steel production by around 20%.
The project also covered the secondary metallurgical facilities and a combined continuous caster that casts billets and preliminary sections, which are then used as the input material for the long-product rolling mill on the site. The secondary facilities include a 100-metric-ton double ladle furnace and a 100-metric-ton double vacuum-degassing plant with mechanical pumps. The new plant enables Tyasa to substantially increase its production capacity and widen its range of products. Primetals Technologies is a joint venture of Mitsubishi Heavy Industries (MHI) and Siemens.
