COMBUSTION BOATSCombustion Boats

Hitemp Combustion Boats are used in the estimation of carbon in steel samples. 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.



 Combustion Bots Size( mm) 75 x 12 x9 85 x 13 x 9 88 x 13 x 10 95 x 13 x 10 100 x 16 x 12 100 x 18 x 13


COMBUSTION TUBES

Hitemp Combustion tubes are used in the Strohline apparatus for carbon & sulphur estimanition . Combustion boat carriying sample of steel is pushed in this tube .one end of Combustion tube is connected to the strohline appatatus & the other end is connected to the oxygen cylinder through a rubber tubing. Essential Properties of combustion tubes are High thermal shock resistance, High softening temperature & highly impervious.Combustion Tubesare made either by slip casting in plaster of paris moulds or by extrution.

MUFFLE TUBE & END CAPMuffle Tube and 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

Sillimanite and 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.



Some Standard Sizes of Crucibles : Grade - 99.5% Al2O3
