Granulation of Pig Iron in Integrated Steelmaking

In integrated steelmaking, the GRANSHOT® metal granulation process is used to handle excess iron.  It is an industrial and high capacity process, up to 360 tonnes/hour. The GRANSHOT unit provides an outlet for hot metal, optimizing the stability of the iron making process which is highly beneficial for campaign life as well as raw material consumption. The GRANSHOT unit has a small footprint and requires less labour and maintenance to be in operation. The Granulated Pig Iron, GPI is a highly interesting product since it can be easily handled both manually and automatically and reused into BF, BOF, EAF, IF etc.

Granulation of metals by the GRANSHOT process

The GRANSHOT metal granulation process can granulate most metals, for instance FeNi, FeCr, FeSi, Basemetals, Steel alloys, etc for an efficient production process that creates an interesting product both when it comes to logistics and metallurgical properties. With over 50 GRANSHOT references worldwide it has proven to be a viable process for both producers and downstream users of granulated metals. At the GRANSHOT Pilot test unit customers can verify how the process and product will be for their specific metal analysis. 
Lately we have introduced the Rotating Tundish solution for improved control and product sizing, applicable for ferroalloys.

GRANSHOT is also suitable to solidify recycled metals. More and more valuable metals are recycled today due to better collection systems and stricter environmental legislatives. The GRANSHOT® process is excellent for handling the recycled liquid metal, creating a good and manageable product for transport and further use.   Examples of recycling areas are dust from the metallurgical industry, waste electrical and electronic equipment (WEEE) and hazardous waste.

UTCAS process control - Level 2 real-time process control platform for the steel shop and ferraolloy producer

The level 2 system UTCAS is always delivered with UHTs AOD & CLU deliveries. UTCAS now also serves as a platform for all other fsteel shop activities such as; EAF, BOF, AOD, LF and VOD/VD. With the UTCAS system is is possible to simualte prior to operation, run real-time process control during production and finally analyse and followup the process after the heat is ready.

With UTCAS there is now one (1) common interface for all steel making operations and that the processes can share and forward information, for instance if the EAF operations goes faster than expected then the platform will inform the AOD operations to slow down and instead run the process more cost efficient etc.

UTCAS can replace existing level 2 systems or be added when level 2 is missing.

Repeat GRANSHOT® Order from TATA Steel.

UHT has received a second order from TATA Steel Ltd. in India for a GRANSHOT® metal granulation unit to be installed at their main integrated steel plant in Jamshedpur, Jharkhand, India. The GRANSHOT unit will have a 300 tonnes/hour granulation capacity to handle excess pig iron from the blast furnace operation. It will be commissoned during 2020. The first GRANSHOT order to TATA Steel Kalinganagar was commissioned in 2016.
GRANSHOT® metal granulation is an industrial and high capacity solution to solidify metal. Granulated Pig Iron, GPI, is a clean, homogenous and easy to handle modern pig iron product that melts rapidly in any downstream melting process. Tata Steel sells GPI under the registered trademark Tata Ferroshots®.

UHT – Uvån Hagfors Teknologi AB is a Swedish technology supplier of GRANSHOT® Metal Granulation units, AOD and CLU® Converter refining plants, and related services for producers of special and stainless steel, pig iron, ferroalloys and base metals.
