Modern Logistical Systems for Transportation of Molten Cast

Jan 21, 2020 · We discuss the transportation of molten pig iron in hot-metal ladle cars and mixer ladle cars at metallurgical plants. It is determined that manual traffic management and entry of data on the amount transported in each ladle or mixer have the most significant impact on molten pig iron transportation efficiency. We review prior work on this problem.

Refractory for Hot Metal Transport and Desulfurization

6.1 Introduction. The transport of molten pig iron from the blast furnace to the steel-making shop is performed in open top transport ladle or torpedo ladle car. Capacity of open top ladle was 60–80 tons. The problems faced by the operators for transporting the hot metal through open top ladle, from iron-making to steel-making shop, are

12.5 Iron And Steel Production - U.S. Environmental

12.5.1.3 Iron Preparation Hot Metal Desulfurization - Sulfur in the molten iron is sometimes reduced before charging into the steelmaking furnace by adding reagents. The reaction forms a floating slag which can be skimmed off. Desulfurization may be performed in the hot metal transfer (torpedo) car at a location between the blast furnace and

Refractory for Hot Metal Transport and Desulfurization - Springer

Jun 10, 2020 · SPerfect Steerable Transfer Carte 1970, alumina refractories were the main lining material in torpedo ladle cars. In past for many years, Bauxite-based refractory was in regular use. Under certain conditions of Perfect Steerable Transfer Cartreased hot metal temperature and aggressive slag corrosion, phosphate-bonded and fired corundum-based bricks wereCustom in 1970–1976.

furnace where the liquid metal is poured into the torpedo ladle. The hot metal resides in the ladle for approximately 4.3 hours for transportation and pouring. On reaching Steel Melting Shop No 2, the vessel is emptied into a transfer ladle for BOF charging. The empty torpedo car returns to the blast furnace cast house for the next charge.

Hot Metal Temperature Forecasting at Steel Plant Using - MDPI

Dec 3, 2019 · Empty ladle time, x 4, exhibits a multimodal distribution showing the different process situations to which the steel plant reacts with a different number of hot metal ladles in service. Daily average of pretreatment time x 3 , is much more centered as can be expected from prescribed desulfurization requirements.

The Basic Oxygen Steelmaking (BOS) Process – Consortium Steel

The Basic Oxygen Steelmaking process differs from the EAF in that it is autogenous, or self-sufficient in energy. The primary raw materials for the BOP are 70-80% liquid hot metal from the blast furnace and the balance is steel scrap. These are charged into the Basic Oxygen Furnace (BOF) vessel. Oxygen (>99.5% pure) is “blown” into the BOF

Desulphurization strategies in oxygen steelmaking - ResearchGate

Oct 1, 2012 · In the LD steel plant of Arbed Saarstahl the hot metal is desulfurised by the submerged lance method in the 140 t hot-metal charging ladle. The process provides for individual or mixed injection

Laser Measurement System for the Refractory Lining of Hot

in a European steel plant with an annual production of pig iron of around 11 million tons. The plant uses 73 torpedo ladles, where 60 ladles are needed for daily operation. The average charging weight of the torpedo ladle is 270 tons. The system was constructed in such a way that the torpedo ladle cars stop to be cleaned (Figure 2).

Multiple Hot Metal Ladle Process | SpringerLink

Nov 16, 2022 · In comparison with torpedo ladle mode, multifunctional hot metal ladle direct transport process has the following advantages: (1) shorter transport time, no need to transfer hot metal to another ladle, shortened process flow, and enhanced production efficiency. (2) Reduced loss of hot metal and heat. (3) Reduced energy consumption and fume

Advances in Steel Refining Technology and Future Prospects

refining process based on hot-metal pretreatment,2) whereby the contents of silicon, sulfur, and phosphorus in hot metal were de-creased before the decarburization in converters, using torpedo ladle cars, hot-metal ladles, or converters as the reaction vessels. Thereaf-ter, technical developments such as the following were achieved:
