Based on feature of low-sulphur steel smelting in PanGang, in terms of optimizing desulfurization technology, reducing resulfurization in converter steelmaking, optimizing desulfurization in LF molten steel refining process and developing RH molten steel refining desulfurization technology. The sulphur content of hot metal can be controlled no more than 0.003%, and that of terminal molten steel can also be controlled no more than 0.005%, which makes the production of low-sulphur steel come true, and the technology route of such steel smelting be established.

Financial Losses

In all processing plants there is a great influence to improve the performance of its overall operation, safety, efficiency and production by the need to reduce the failure of its equipment. Equipment failure; even on very rare occasions, can result in great economic and financial losses. As a result of many uncertainties originating from the design and operation of the equipment at a plant there are some failure risks that cannot be avoided. In this article, the reliability of a steel refining process was predicted. Two failure modes were investigated for each type of equipment from which the reliabilities were used to determine the overall plant reliability. The maximum plant reliability was found to be 98.0%. It was noted that even though a high reliability prediction was found, it is important to employ preventative maintenance on the plant to ensure the consistent operation of the equipment and maintain the reliability.

Strength Improvement

The use of industrial waste as a component of nowadays building material has become of major importance due to the underlining of environmental and sustainability issues. Among these materials is Ground Granulated Blast Furnace Slag (GGBFS), often referred to as slag-cement. The material is a residue produced during the steel refining process. The cementitious nature of the product makes it most suitable for ordinary Portland cement (PC) substitution. However, the behavior of this slag-cement in terms of development time and strength has not been defined in great details. In the construction industry, time is of major importance, a prolonged hydration process could delay the overall process. This research work focused on the setting time and strength response of slag-cement in mortar. The ratio of mortar constituent of cement-to-sand was 1 : 3. The percentage of slag-cement substitute to PC was 0%, 25%, 50% and 75% to the cement weight. The compressive strength was tested at the age of 14 days and 28 days. The results of the analysis showed that at a 25% slag-cement substitution a very significant increase in strength was shown. The increase was more pronounced at the age of 28 days when compared to 14 days and recorded to be 31.90%. As for the 50% and 75% slag-cement substitution, no significant increase in strength improvement was noticed. The test results showed a 2.66% enhancement for the 50% slag- cement substitution and a 2.45% increase for a 75% slag-cement replacement. The study also showed that slag-cement required a higher water-cement factor for the normal consistency
