The coal coke is 13M long, 0.42M wide and 4.5M high. The cake has to be pushed length-wise into the coke oven - the gap between the coak cake and the side walls of the coke oven being merely 15mm. Therefore, a little misalignment in the positioning of the SCP machine will make the 80 ton cake hit the wall of the coke oven causing disaster.

Specially in the area of Coke Plant & Environment and completed projects to achieve Ambient air Quality index, stack emission, Zero effluent discharge and utilization of Solid waste.
On average, bituminous coal, which is the type of coal mined in ia, contains at most 0.01 percent of any one toxic constituent, that being manganese.^6 A coal mining and processing facility emitting 1,000 tons/yr of fugitive coal dust would therefore emit only 0.1 tons per year of manganese.
The Phase 1 of the plant consists of a 3.3 million tonnes Blast Furnace (4,330 cubic metre capacity), Two Coke Ovens- stamp charged gas recovery type batteries of 1.5 million tonnes of gross coke, Sinter plant with a gross production capacity of 5.75 million tonne, Steel Melting Shop with the largest converter in India (310 Tonne) and Hot Strip ...
Jan 01, 2019· Worldwide, the cokemaking process has remained more or less unchanged for over 100 years, and metallurgical coke is produced in recovery and nonrecovery coke ovens by using top gravity and stamp charging and a wide range of coal bases.As BFs have been operated with coke, it has been urged globally to reduce the coke cost more by maximization of cheaper/inferior coal in the blend.
The plant produces high-quality metallurgical coke and was in danger of being closed which would have led 210 people to lose their jobs. In August 2019, NLMK group has embarked on the assembly of main process equipment for the implementation of the stamp charging technology at the operating coke oven battery at Altai-Koks.
