Evolution of the company

Coke Oven Plant Overview

  • The Company has two coke oven batteries of 30 ovens each with the installed capacity of 142,065 TPA of coke
  • Most of the ovens in battery 2 are not in operating conditions. However, ovens in battery 1 are in good shape
  • SBQ has adopted a conventional coke making technology using a battery of ovens sandwiched between heating walls. The coke ovens are non recovery type
  • Coke oven design is from Centre for Fuel Research of India (CFRI) India. Equipment from Sino-Steel Industry & Trade Corp. (SSIT), China
  • Uses an eco‐friendly stamp charging process which allows to blend varieties of coal leading to cost efficiencies
  • Uses top charging method to input coal in ovens leading to control on process waste

 

Mini Sinter Plant overview

  • Around 24 sq. meter of Sinter Plant, it has a capacity to produce a total sinter of 260,700TPA Plant has been manufactured and supplied by TRF Minitec, Brazil. TRF was the licensee for Minitec Brazil who provided the design
  • Agglomerating iron ore fines and fluxes to produce feed for blast furnace may resulting in significant savings
  • Abundant availability of iron-ore fines and fluxes such as limestone, dolomite and quartz in India
