The electromagnetic stirrers are used in the continuous casting process to improve the product quality and to increase the steel production. According to the position along the casting strand and metallurgical effects, stirrers can be classified mould, strand and final stirrers. The benefits obtained using one or more EMS in combination include surface and sub-surface quality, internal and central soundness as segregation, porosity and central cracks.

Maintain the powder thickness constant in the mould is a very important task to avoid level fluctuation and to improve steel quality keeping constant the heat transfer, the lubricating powder film and also increasing the surface quality. Automatic Mould Powder Feeding system – MPF is a device designed for CCM with protected pouring in which it is necessary to automate the powder feeding on the liquid pool into the mould. The automatic Mould Powder Feeding system – MPF is designed to work for any casting section and casting format (billets, blooms and slab).

The key impact of mould powders on the quality of cast steel is widely recognized. Specifically, the ability to maintain constant powder thickness and stable meniscus position is essential to cast quality steel. Mould powder thickness can be controlled through closed-loop automated powder feeding. Ergolines’ Ultrasonic Level Detector (ULD) is a new sensor dedicated to the real-time measurement of mould powder thickness. Closed-loop powder thickness control is implemented by using the ULD feedback to drive an automated powder feeding machine, leading to improved steel quality and process stability.
The ULD can be used either in combination with a pre-installed radiometric sensor or with Ergolines’ OPD.
