Tube Furnace
The sample of steel drilling is taken in a combustion boat and placed inside a tube furnace maintained at 1300 deg to 1400 deg & oxygen is passed over it which combines with carbon of the steel & CO2 is estimated. Propirties of combustion Boats are High thermal shock resistance, High softening temperature & high resistance to corrosive action to molten steel. Combustion boats are made either by slip casting in plaster of paris moulds or by mechanical pressing.
...morethermocouple beads
Hitemp thermocouple sheaths are used as protective covering over sensing elements. So that the elements are protected from the injurious effects of the furnace atmosphere. These thermocouple sheaths are manufactured either by slip casting or by extrution. Vacuum Extruded thermocouple sheaths are dense & highly impervious & give better life compared to conventional slip casted ones .
...moreCeramic Tubes
are used for supporting coiled shaped heating elements made out of Kanthal Nicrome wire used in resistance wire furnace. These tubes have high softening temperature & excellent thermal shock resistance. Hitemp has mastered different compositions to meet out typical air quenching requirements also. These tubes are available in standard diameter with length upto 1500mm.

...moreceramic crucibles
Crucibles are fabricated by slip casting method .They are highly refractory to withstand desired temperatures ,They posses have high thermal shock resistance. These are highly dense to ensure no loss of contents by absorption & are highly resistant to corrosive action of the contents.Used is Laboratories for Chemical Analysis & melting of glass & metals in industries. Alumina crucibles are used for coal analysis & melting rare metals & high melting point alloys. Alumina crucibles are highly resistant to acid & basic slag.
