Modernisation of meltshop ACERINOX, Palmones, Spain, has awarded SMS Siemag, Germany, and SMS INNSE SpA, Italy, a contract for the supply of an AOD converter vessel and the modernisation of an electric arc furnace supplied in 1998. SMS INNSE supplies an AOD converter vessel and two change vessels with a tapping weight of 108 tons. The converter design was optimised on the basis of studies that Acerinox had previously ordered from SMS Siemag. SMS Siemag’s study investigated the vibrations that occur during the AOD blowing process on account of bath movements. Comprehensive measurement series were recorded and evaluated throughout the campaign of the refractory lining. On the basis of this data, SMS INNSE examined the effects on the service life of the converter tilting gear unit. SMS INNSE will modernise the valve station (O 2 , Ar, N 2 , air), which will receive an individual shrouding-gas control system. Also included in the scope of supply are the engineering, the mechanical equipment and the supervision of erection and commissioning. The electric arc furnace with a heat size of 120tons will be modernised by SMS Siemag. The spout-tilting electric arc furnace supplied in 1998 will receive a new furnace roof. The former conventional type of roof will be replaced by a spray-water cooled furnace roof. This patented method of roof cooling uses water at atmospheric pressure, reducing the potential risk that large amounts of high pressure water present in case of leaks. SMS Siemag’s scope of supply includes the engineering, the supply of the mechanical equipment, electrical equipment and automation system, and the supervision of erection and commissioning. The AOD converter is to start production this year, while the electric arc furnace is scheduled to be commissioned in 2013.

The new machine is a Mazak Integrex 200SY six-axis turning mill centre with sub-spindle. The main goal of this machine is to produce more parts in-house for both quality and delivery control improvements. The machine has dual, opposed powered chucks with a live milling tool for true ‘done in one’ manufacturing capability. The addition further reinforces the company’s commitment to the ‘Made in USA’ philosophy that is still important to its customers.
