17 March 2021 | Evolution of raw material selection for Refractory Materials 3
● Refractory markets estimated to have declined by around 8%
○ Strong variance globally ○ Covid related drop in EU/Americas ≈20%○ China rebound in Q3/Q4
● The two sides to the Refractory market
○ Acid v Basic minerals ○ Monolithic v Shaped products○ China production v ROW
● Production linked to value & usage○ Long shelf life items more likely to travel ○ Repairs & maintenance more likely to be
sourced locally ○ Ability to solve customers problems
drives local solutions
Refractory Market was impacted heavily across 2020 with COVID striking consumers forcing a reduction in non-critical activities
With plants forced to reduce both production and repairs & maintenance activities, with onsite personnel limited, the typical day to day activities have been reduced across the board
Basic : Acid materials (55/45)
Brick : Monolithics (57/43)
China : ROW production (60/40)
≈37 MMT

● Applications are the final use of the refractory○ Installed operational unit will be a complex design
of multiple materials often combining shaped and monolithic products
● Refractory needs split between ○ Green Field / Brown Field → Capex (Investment) ○ Repairs & maintenance → Capex (discretional) ○ Process consumables → Opex (Production)
● Product is chosen based various design philosophies
including: ○ Installation type ○ Usage temperature ○ Process experience
● Cost of ownership remains key influence ○ Unit cost ○ Total cost installed ○ Total cost - lifecycle
Understanding where and how these products are used are critical to grasping market dynamics

The value proposition of refractories create multiple solutions to what is considered a unique application
● Consider a typical tundish○ Transition point from batch process through steel
making to the continuous casting process
● One component of tundish: Permanent Lining ○ Application needs
● Thermal cycling ● Crack resistant / structural integrity ● Chemically resistant (no sticking) ● Low heat losses / maintain bath
temperature

● Andalusite ● Low CC
● MULCOA & Kyanite● Low CC
● Bauxite ● Phos bonded brick
Tundish permanent lining● Refractory material
between steel shell and the parting coat
● Flow control components inset into the permanent lining
● Parting coat applied over lining / not in direct steel contact

Depends on industry & type of job
○ Refractory producers will produce and recommend products based on knowledge of application within cost to serve expectations
○ Steel repairs and maintenance■ Internal refractory stewards■ Mix of internal / external workforce
→ Reduce operational costs
○ Cement kiln annual repairs ■ Maintenance contractor in place■ Refractory recommended by suppliers
→ Meet ‘ontime’ unit start up
○ Greenfield processing units■ Signed off and specified by ‘OEM’ ■ Technology providers / designers
Pechiney & Aluminium → Target to meet ‘warranty’ timeline
How do these decisions get made? By who and why?

● Products are designed to contain high temperature processes in a safe manner
● No easy way to say this, failures can result in fatalities. This is unacceptable on any level
● Consequently, by its nature you have a relatively conservative decision making approach wrapped in data & experience
● Change has to be to create value & the value creation has to be validated.
● Only 3 ways to create value ○ Reduce risk ○ Reduce time ○ Reduce cost
Refractories are about creating a safe working environment

● Refractories are a High Visibility cost
○ Refractories represent a relatively low portion of plant production costs
○ But represent high proportion of ‘impactable’ costs that the local teams can have on the total running costs.
● Optimal solutions targeting specific needs of the decision maker
○ Innovator: Reduce down-time / faster return to service■ Brick > Casting > Dry Gunning > Wet Shotcreting ■ Time to install / return to service / economies of scale
○ Curator: Managing price & risk ■ Better matching of available reserves with applications■ Upgrading of downgrading RM necessary when
adapting solutions■ Inclusion of recycled materials / balancing cost & usage
Refractory solutions have been driven to create value through understanding of customer needs
17 March 2021 | Evolution of raw material selection for Refractory Materials 10
● Cannot replace a bauxite brick with bauxite castable ○ Monolithic binders increase shrinkage○ Require compensation aggregate or upgrade material
● Shortage of bauxite combined with upgrade necessary has
seen an significant increase in Tabular Alumina capacity○ Flow on into global markets for WFA & Tabular
China’s blue sky policy: the ripple impact in full effect...
● Chinese Blue sky policy has heavily impacted the Bauxite and Magnesia industry as well documented
● With curtailments in use of coal fired burner for industrial kilns, impact was also felt in refractory fire bricks with demand leading to significant cost increases
● With Increasing price of bricks - led to a change in value proposition with increased usage of monolithic materials

Potential external influences on the ‘optimal solution’ for refractories are widespread & considerable
● The committed road map of global steel makers to ‘net zero’ or similar targets as announced by ArcelorMittal
○ Move to EAF furnaces away from traditional Blast Furnace○ Return of DRI processes with hydrogen / alternate fuels
● Electrification of Vehicles industry with targets in China & EU○ Reduced dependence on Internal combustion engines ○ Flow on to sub-segments (investment casting) for
turbo-chargers and other specialty products.
● Portland Cement targets to reduce emissions○ Alternative fuels / hydrogen mix ○ Electrification of kilns and processes
17 March 2021 | Evolution of raw material selection for Refractory Materials 12
So, how could a company global strategy impact a Refractory decision maker actions and the ‘optimal solution’?
Consider a hypothetical steel company who have a stated ‘target’ to reduce CO2 footprint. ● Management passes these targets on ambition to the process unit decision makers ● Decision maker has this transformed into his financial objectives ● Running a tender process on steel ladle floors with competing suppliers● Decides to incorporate a ‘carbon footprint’ on selection criteria on tender process
→ 3 products made it to final round, all based on white fused alumina & all have passed internal testing protocols and are approved for use, however each have a different process route:
Assuming all other inputs being equal → Decision will be for the lowest Carbon footprint
Introduction of an economic value on CO2 ● No longer just supply chain and energy ● Alternative materials options ● Total life cycle impact ● Unit value of price and carbon comparison
→ Triple bottom line

Summary & Conclusions
17 March 2021 | Evolution of raw material selection for Refractory Materials 21
● Refractory customers have in a way by necessity been the first adopters of the circular economy, with efforts to reuse and consume less, this has been at the heart of the ‘optimal solution’ in terms of economic value before it became more broadly known.
● Refractory Producers, as solution providers that tailor their offer to their customers needs, are seeing increasing consumer awareness and targets for the whole value chain around CO2 footprints, creating a new variable to the evaluation process.
● History has proven that changes in political & social landscape impact the value proposition for refractory products and will have an impact on the ‘optimal solution’
○ Historically with labour costs & Installation methodology ○ How raw materials are used and consumed geographically; and now ○ Supply chain and process methodology of those raw materials
● As a company, and specifically within the Refractory team, Imerys are aligning our innovation efforts within our plants, processes and products to meet the challenges of our broader society. To deliver refractory raw materials that are sustainable and offer the most flexibility to our customers to achieve the ‘optimal solution’
