Because of small termal efficiency, high prices of oil, long duration of process,....
Today steel is mainly made by electric arc furnace and by converters. Converters use only oxygen for refining blast furnace iron. Electric arc furnaces can melt scrap steel much faster than in the old open hearth furnaces. Much of disadvantages of open hearth furnaces are solved in electric arc furnaces and converters. Open hearth furnaces can't melt high quality alloy steels, but they can melt very good quality construction steels. They are still in use by Russians about 30% and Ukrainians 50% and other former soviet countries. The open hearth furnaces was more then a century the symbol of a steel making.

What are the disadvantage of open hearth process?
It took a long time
When was the Open Hearth Furnace invented?
In 1865, the French engineer Pierre-Émile Martin took out a license from Siemens and first applied his furnace for making steel. Their process was known as the Siemens-Martin process, and the furnace as an "open-hearth" furnace.
What are the limitations of open hearth steel making process?
The open hearth steelmaking process has several limitations, including its low production efficiency compared to modern methods like basic oxygen steelmaking. It requires a longer processing time and higher energy consumption, making it less cost-effective. Additionally, the open hearth process produces greater emissions and pollutants, which raises environmental concerns. Finally, its inability to effectively utilize scrap steel limits its adaptability in a recycling-focused industry.

What is a advantages of open hearth furnace?
The open hearth furnace offers several advantages, including its ability to produce large quantities of steel with a consistent quality, making it suitable for mass production. It allows for the use of a variety of raw materials, including scrap steel and pig iron, which can reduce costs. Additionally, the open hearth process provides good control over the chemical composition of the steel, enabling the production of specialized steel grades. Finally, it has a relatively low initial investment compared to some modern steelmaking technologies.
