"GAS CUPOLA" ENTERPRISE

The gas cupola is a slightly reconstructed shaft furnace. Reconstruction is carried out inside the shaft. The design of the cupola makes it possible to convert a cupola of any efficiency into a gas fed cupola with maximum unification and small capital investments without supplementary operating spaces. In the gas cupola cast iron of required chemical composition can be obtained without burden price rise as compared with smelting with coke; mechanical qualities of obtained cast iron suit any mark of gray pig iron.

The experience of the last years of inculcation of Gas cupola furnaces at many factories in Russia, the CIS countries, and Italy showed that:
- 40 - 60 % of steel crop can be used in the burden
- the temperature of cast iron reaches 1530°C
- if there are 40-60% of steel in the burden, the content of carbon may reach 3,7-3,9%
- a cupola can work for 2 - 3 weeks without repairing
If gas is used for all coke cupolas, it will result in:
- reduction of harmful wastes (from 6000 mg/m3 to 15-25 mg/m3).
- economic effectiveness (according to the prices of January, 2000 in Russia the saving will amount to 150 - 200 roubles per ton of cast iron; according to the USA prices it will be $ 15 - 20 per ton),
- high quality of cast iron with low content of sulphur.
