METALLURGICAL COKE

LOW ASH METALLURGICAL COKE

Sesa Goa's MetCoke Division operates 84 non-polluting, non-recovery type coke ovens producing 280,000 MT of low ash metallurgical coke per annum . The coal requirement is met through imports from Australia and China and the coal mix is designed to produce low ash premium quality coke. About 60% of the capacity of the coke oven plant is consumed in house by the blast furnaces of Sesa Industries Limited.

Note: + / -1 % in the above specifications permitted. Size and specifications are indicative and can be modified to suit customer requirements. Stowage factor of Coke is 56 cuft / MT. Size: undersize: 5% max, oversize: 5% max

The analysis of coke is carried out using the following standards:
CRI & CSR

4023:1991

Advantage for Blast Furnaces: are low coke rate, guaranteed CRI, CSR, Ash, sulphur and phosphorus, high fixed carbon and low volatile matter and good size gradation.

Advantages in Foundry Cupolas: are high NCK values, high metal to coke ratio, high metal temperature, high carbon pick up and good size gradation.

Advantages in Ferro Alloys: are high FC, less consumption per ton of output and good size gradation.

Advantages in Mini Cement Plants: are high FC and low ash.

The superior quality in terms of CRI and CSR is produced as a result of the relatively higher operating temperatures and longer coking cycle. A special feature of the technology is the extremely low levels of air pollution achieved as the ovens operate under negative pressure and at a temperature at which all potential pollutants are broken down into combustible compounds.

The bi-product of this technology is clean electrical energy. Sesa is in the process of setting up a 30MW power plant based on the Coke oven fuel gas and Sesa Industries Limited blast furnace gas . It is intended to establish the power plant on a BOO basis.

Sesa's coke is designed for the requirements of the foundries, blast furnaces, zinc smelters, cement and the Ferro alloy industry and offers advantages like consistency in quality, sizing and uniform temperature thereby reducing cold spots and metal wastage.

PIG IRON

LOW PHOSPHOROUS NODULAR/FOUNDRY/BASIC PIG IRON

A major portion of the 250,000 tons of pig iron manufactured by Sesa Industries Limited caters to niche markets and VALUE ADDED applications. We produce compositions within fairly narrow ranges of specifications with the objective of optimising customer's costs due to non-addition of additives, standardization of process parameters and process procedures and minimization of rejects.

Our customers comprise some of the most reputed foundries in India who manufacture automobile components and include Ghatge Patil Industries - Kolhapur, Ashok Iron Works - Belgaum, Cummins India Limited - Pune, Telco -Pune, Mahindra & Mahindra Limited - Mumbai, Punjab Tractors Limited - Ludhiana. Majority of Bangalore and Coimbatore based foundries like Goetze India Limited of Bangalore, CPC Limited and Texmo Industries of Coimbatore.
Currently approximately 20% of annual production is being exported.

We also produce two grades of ductile iron grade pig iron SG50 & SG60, which we also supply to Indian manufacturers of automobile components.
