Sigma

	Sigma-E Plus	Sigma-E	Sigma HT	Syncarb Z2e2

Introduction	Sigma-E Plus is the latest variant of crucibles launched by Morgan. It is a high quality; clay-bonded, silicon carbide graphite range of crucibles manufactured using precise Isostatic pressing technique. It is a new variant of Sigma HT crucibles, developed for low temperature applications. It gives excellent oxidation resistance, good product life and improved energy efficiency. These advantages lead to better 'value' of ownership for end customer.	Sigma E crucibles are the premium quality, clay bonded, silicon carbide - graphite range of crucibles offered by Morgan. These are manufactured with the world acclaimed Iso-Static Pressing technology. These are developed for application like aluminium scrap melting in coke, oil and gas fired furnaces	Sigma HT crucibles are the premium quality, clay bonded, silicon carbide - graphite range of crucibles offered by Morgan. These are manufactured with the world acclaimed Iso-Static Pressing technology. These are specially developed for high temperature application like zinc distillation and copper alloy melting. They also find application in cast iron melting in small sized crucibles in coke, oil and gas fired furnaces	Syncarb Z2e2 is a premium quality hybrid ceramic bonded clay grapite with a high carbide and graphite content is manufactured through an advanced Iso-Pressing Technology.
Applications	Al and its alloys melting in electric resistance and fuel fired furnaces Zinc and its alloys in electric resistance and fuel fired furnaces	Aluminum Scrap (Melting)	Aluminum, Zinc & its alloys Cast Iron (Melting)	Aluminum, Zinc & its alloys Cast Iron (Melting) Syncarb Z2e2 is dsigned to perform exceptionally well to melt and hold aluminium and other low temperature alloys in gas Fired and Electric resistance furnaces
Typical Operating Temperature	450 – 900 °C	700°C to 1400°C	900˚C - 1600˚ C	400˚C - 1000˚C
Typical Operating Temperature	Please follow recommended pre-heating cycle
Performance Characteristics	High oxidation resistance Consistency and repeatability of performance Good mechanical strength Good erosion resistance Excellent thermal shock resistance Higher density offer better conductivity and lower energy consumption	Very good thermal conductivity High mechanical strength Excellent resistance to chemical attack	High erosion resistance at elevated temperatures leading to longer product life Faster melting through consistently high thermal conductivity, resulting in better energy efficiency Non wettability due to higher product density and use of special quality graphite in manufacturing Consistent performance and repeatability High mechanical strength Good resistance to chemical attack	High thermal conductivity & Very high energy effciency Superior oxidation resistance High mechanical strength & good erosion resistance High consistency in performance & repeatability Longer life
Identification	Sigma-E Plus crucibles are finished with a GREY colour and the top rim is painted Parrot Green	Dark grey (Suffix 'HT')	Sigma HT comes in dark grey color and the models are suffixed with letters 'HT"	Dark grey (Suffix 'Z2e2')
