We can supply the Corhart design in 200 kg., 300 kg. and 400 kg. capacities


It is important to heavily insulate the AZS Glass Tank as part of the furnace design. This insulation not only saves energy (and dollars) but it also helps to dampen the effect of normal temperature fluctuations, thereby lessening the potential for thermal shock (cracking) of the fused cast material.
During the melting of your glass batch or glass cullet, we suggest several small charges rather than one large charge. This practice will dampen the severity of the temperature swings in the melter, and minimize the thermal shock to the refractories.
Tank depths greater than 12 inches can be supplied.
The great advantage to this liner beside long life is there are only two seams which facilitates ease of construction.
The estimate of the glass capacity is based on soda/lime glass with a cu. ft. weight of 160 lbs. I have built 4 furnaces using this block and each lasted 7 years of continuous use in a university environment. The life expectancy of any furnace is dependent on a number of factors. The primary factors are: Type of glass used (batch or cullet), melting and working temperature, number of charges per week, how active your glass is (viscosity). Regardless, an AZS liner when used correctly will outlast any other type of liner.

How to Calculate the Glass Capacity of a Day Tank
- Length x Width x Height in inches.
- Divide the answer by 1728 (cube root)
- The answer is the dimension of your furnace in cubic feet.
- Multiply the cubic feet by 160 (weight of soda/lime glass pre cu. ft.)
- The answer is the capacity of your furnace in pounds of glass.
If you want the answer in Kilo capacity divide the pounds by 2.2
lbs./ft.³= 160
kg/m³= 2,562
