Laboratory Ceramic Products

Hitemp Combustion Boats are used in the estimation of carbon in steel samples. The sample of steel drilling is taken in a combustion boad and placed inside a tube furnace maintained at 1300 degree to 1400 degree & oxygen is passed over it which combines with carbon of the steel.

Ceramic Furnace Supports

Hitemp Element supporting tubes are used for supporting coiled shaped heating elements made out of Kanthal / Nicrome wire used in resistance wire furnace.

Thermocouple Tubes, Beads & Sheaths

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.

Kiln Furniture

These are used for holding the material to be heated & to optimise the furnace loading . These have high thermal shock resistance , high Refractoriness under load, High Cold Crushing strength & repeated heating & cooling Cycles.

Super Refractory Shapes

Hitemp insulation refractories are meant for applications where high mechanical stability and insulating properties are required. Hitemp refractories are best suited for insulation of kilns and furnaces, both as hot face and back up linings.

Thermocouple Tubes, Beads & Sheaths

THERMOCOUPLE SHEATHSTHERMOCOUPLE SHEATHS 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 . THERMOCOUPLE BEADS Hitemp thermo couple beads are used to provide electrical insulation to the couple which is used for sensing the temperature inside the furnace. These are single, twin , Four hole bore . These are generally used in small lengths of 25mm. However longer lengths are sometime preferred in critical applications.

Muffles are mainly used in muffle furnaces where heating elements made out of kanthal / Nircrome wires wraped round the muffles generally in the form of coils & inside these muffles objects are kept for heating either for laboratory or industrial purposes. these muffles are made in different Square/ rectangular dimensions . Hitemp Muffels are thin walled for quicker heating. These are rodust in constructions Highly thermal shock resistant. GROOVED REFRACTORIES Grooved refractories are mainly used in High temperature muffle furnaces. The heating coils made out of kanthal / Nircrome wire coils in U Shapes are placed in the groove of the refractories. Higher temperature in these furnaces is achieved as objects are heated directly by radiation . Hitemp Grooved refractories are thin walled & light weight for faster heating . By using Hitemp Grooved refractories peak temperature is attained in almost 1/4th the time as compared to conventional grooved refractories available in the market.These are robust in constructions Highly thermal shock resistant. BUNSEN BURNER CRUCIBLES Hitemp Bunsen burner crucibles are used to support heating element on the outer side of their conical structure & inside provides sufficient space for keeping small samples or test tubes

ELEMENT SUPPORTING TUBES/ ROUND MUFFLES Hitemp Element supporting 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. TUBE HOLDING BRICKS/ELEMENT HOLDING BRICKS Tube holding bricks are used to support the element supporting tubes where as element holding bricks carry the elements directly in their grooves. COLLAR TUBES/ COLLAR BUSHES Hitemp Collar Tubes are used for taking out the electrical terminals from the furnace & to help insulate the structure from the electric current , these tubes are not subjected to the peak furnace temperature yet theses must be strong enough & do not get broken. GAS PASSING TUBES Hitemp gas passing tubes are used to carry different gases to maintain atmosphere in the furnace . These are also used to provide stirring in the molten noble metals in addition to the desired inert atmosphere. MULTI HOLE DISC Hitemp Multi hole disc are used in the radiant metallic heaters to insulate elements from the metal tubes. These Disc have high mechanical strength as well as high thermal shock resistance. CUP LOCKS, BOBBINS, WASHERS These are used for holding the ceramic blankets in place. These products have high mechanical strength as well as high thermal shock resistance

MUFFLE TUBE & END CAP Hitemp Muffle tube is an integral part of combustion furnace used in strohline apparatus. Two end caps are fitted on each side of muffle tube for holding the SIC Heating elements & Combustion tube. There is a centre hole in muffle tube to insert thermocouple. Muffle tubes are made either by slip casting in plaster of paris moulds or by extrution. Where as End caps are made by die pressing. End caps are available with 3 & 4 holes. LECO CRUCIBLES Leco Crucibles are used in the estimation of carbon in steel samples. The sample of steel is taken in a leco crucible and placed inside the leco apparatus. Propirties of Leco crucilbles are High thermal shock resistance, High softening temperature & high resistance to corrosive action to molten steel. Leco crucible are made by mechanical pressing. SILLIMANITE & ALUMINA 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.
