Metal Granulation articles
Granulated metal product from direct tapped furnace – experience from operation at BEFESA Sweden
Granulation of metals, the GRANSHOT® process, as discussed in this paper for ferroalloys, is today an economically viable and well proven industrial solution with well over 40 installations made by UHT.
This article describes GRANSHOT® iron granulation technology, operational experience and the usability of the end product in steelmaking operations.
Since the start up of the Befesa ScanDust plant more than 1 Mt of stainless steel making residues has been recycled and approx. 500,000 tons of valuable metals recovered. By granulating the recovered metal via the GRANSHOT® granulation process a high process yield is achieved. The product, granulated API, is returned to the steel makers or sold on the open market.
This paper discusses the principal layout of the Granshot® plant, operational experience, and the usability of a Granshot® granulation plant and the product in steelmaking operations.
The Granshot granulation process is a cost-effective method of handling excess iron at high capacity, low cost and producing prime product material for re-use.
The purpose of this diploma project was to study the energy flow in the GRANSHOT®-process and analyze different methods to make use of the developed energy. The investigation contain analyses of the economical consequences of an eventual implementation in the GRANSHOT®-process and a simple layout design of a granulation facility with implemented energy recovery technology.
Installation of a granulation route for iron handling downstream from the iron-making unit in an integrated steel plant has proven to be a feasible solution in order to boost total plant steel output
This paper describes an experimental study of the relative merits of different melt stock materials with focus on melting times, chemical analysis accuracy and material handling properties.
The Iscor Saldanha Steel has successfully installed a Granshot™ metal granulator to accommodate excess iron production from the Corex. This paper discusses the iron granulation method compared to traditional alternatives such as sand bed pooling.
