New concept for HSM downcoiler mandrel replacement

Thai steelmaker Sahaviriya Steel Industries contracted Danieli Service for replacement of a downcoiler reel for its hot-strip mill located in Bang Saphan, Thailand.

Once upgraded with Danieli technology the downcoiler, which was originally designed by another steel plant manufacturer and in operation since 1994, will benefit from a considerable reduction of maintenance cycles with a service life projected at over 1.5 million tons.

The dedicated mandrels design team of Danieli Service was able to comply with all specific customer’s requests, winning the technical-commercial tender.

A completely new kinematic of the machine was developed and now the new reel is being manufactured at Danieli workshops in Italy, where special materials and processing are available at the highest standards. The gearbox also will be refurbished at Danieli Thailand workshops in January 2021, whilst the plant will continue normal operation.

The project witnesses the Danieli Service skill to customize and improve plants and equipment according to specific customer requests, incorporating given OEMs.
