pellet and sinter in blast furnace operation

2021-7-8  Results of calculation for BF of OAO "MMK" operation with high proportion of acid pellets of Sokolov Sarbai Mining Beneficiation Plant in the charge with various content of local sinter are presented. Increasing in proportion of pellets in metallic burden leads to reduction in magnesia concentration in the blast furnace slag.

COMPARISON OF SINTER AND PELLET USAGE IN AN

2020-7-20  Hatch has compared the merits of using sinter and pellets in the blast furnace to help steel producers evaluate the impact of increased pellet usage in the blast furnace burden. 2.2 Comparing Sinter and Pellets Sinter and pellets are agglomerated forms of iron ore, both suitable for use as blast furnace burden materials.

Influence of Sinter and Pellets on Blast Furnaces

Abstract. Results of the analysis of physical-chemical properties of sinter and pellets are presented. It shows that at BF transition to operation with high proportion of acidacid pellets in furnace charge, it is necessary to change the basic parameters of the slag mode as well as furnaces loading practice.

Optimum Pellet Basicity Desirable for Blast Furnace

2021-2-20  As, the blast furnace is fed with alternate layers of coke and iron-bearing materials such as sinter, pellet and iron ore. Thus, when pellet CCS is low, it crumbles into powder, which clog the bed voidage. As a result, the gas permeability in the bed gets negatively affected to hamper the efficient blast furnace operation.

Use of Iron Ore Pellets in Blast Furnace Burden

2014-6-13  Sinter, pellet and the calibrated lump ores are the three iron bearing metallics normally used in the blast furnace burden. Uses of all the three metallics in blast furnace burden can vary from zero to hundred percent with adjustment of the furnace parameters. These three metallics can be used in any combination of two metallics or three metallics.

Blast Furnace Performance Under Varying Pellet

2018-12-18  The blast furnace (BF) is a counter-current gas–solid chemical reactor in which iron-bearing materials, namely iron ore, sinter and pellet and fuel mainly coke, are charged from the top of the furnace, while hot blast enriched with oxygen and steam is blown from the bottom of the furnace through tuyeres.

Blast Furnace Performance Under Varying Pellet

2018-12-18  As a promising method to strengthen the blast furnace smelting and to realize reduced fuel operation, high-proportion pellet charging has become the practice of BF ironmaking. Use of pellet gives rise to uniform bed permeability in comparison with iron ore or sinter. This leads to better gas–solid contact resulting in higher productivity at reduced coke and fuel rate.

Operation at High Pellet Ratio and Without External

During a campaign in the LKAB Experimental Blast Furnace, pellets and sinter were operated at an ultra low slag volume. A high amount of pellets was balanced with high basicity sinter. An improved blast furnace operation is shown when operating at ultra low slag volume and without external slag formers.

Operation of an experimental furnace with pellet and

At low driving rates, the lowest coke rates were obtained with burdens composed of 100% fluxed sinter. At higher driving rates, however, good pellet burdens gave the better coke rate and the higher productivity. Nevertheless, the tests run with a 100% sinter burden at high driving rate should be repeated, as the sinter contained a higher percentage of fines (0-3/16 in.) than during the first test.
