Abstract

The invention belongs to the technical field of steelmaking, in particular to a high-efficiency steelmaking process for a steelmaking furnace. The steelmaking furnace used in the high-efficiency steelmaking process comprises a base and a steelmaking furnace body arranged on the base; an oxygenator, a smoke exhaust pipe, a treatment absorption unit, an air outlet pipe, a motor and a controller areincluded; the controller is used for controlling the steelmaking furnace to work; the oxygenator is arranged on the base, the oxygenator communicates with the steelmaking furnace body through an oxygen conveying pipe, and the oxygenator is used for oxygenation to the interior of the furnace body; and one end of the smoke exhaust pipe is arranged at the top of the steelmaking furnace body, a preparation barrel is placed in the steelmaking furnace, and a calcium hydroxide solution is prepared in the preparation barrel. Efficient heating and drying are carried out on coke particles by using heatgenerated by preparing the calcium hydroxide solution, and the contact area between the coke particles and hot air is greatly increased, so that the coke particles are efficiently heated and dried, and the steelmaking efficiency of the steelmaking furnace is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of steelmaking, in particular to a high-efficiency steelmaking process of a steelmaking furnace. Background technique [0002] Steel is a general term for iron-carbon alloys with a carbon content between 0.02% and 2.11% by mass. Human beings have a long history of application and research on steel, but until the invention of the Bayesian steelmaking method in the 19th century, steel Production is a high-cost and low-efficiency work. Nowadays, steel has become one of the most used materials in the world due to its low price and reliable performance. It is indispensable in the construction industry, manufacturing industry and people's daily life. Composition, steel is obtained by putting pig iron for steelmaking into a steelmaking furnace and smelting it according to a certain process. [0003] In the existing technology, it is necessary to add coke particles in the steelmaking furnace for assistance during s...
