Method for obtaining energy consumption per ton of steel in continuous annealing unit

Abstract

The invention provides a method for obtaining energy consumption per ton of steel in continuous annealing unit. The method comprises the following steps: S1: obtaining a training parameter of a stripsteel, which comprises a width l, a density rho, a thickness d, and a speed v of the strip; S2: constructing a kinetic energy consumption model of the steel strip in per unit time to obtain Q dynamic,and constructing an energy consumption model in the continuous annealing unit in per unit time to obtain Q combustion, wherein Q combustion is the total heat income of the continuous annealing unit in per unit time, Q dynamic is the kinetic energy consumption of the steel strip in per unit time; and S3: obtaining a Q ton which is the energy consumption of the continuous annealing unit by using acomputational formula calculating the energy consumption per ton of steel in the continuous annealing unit, wherein the computational formula calculating the energy consumption per ton of steel in thecontinuous annealing unit is Q ton = ( Q combustion + Q dynamic ) / m = ( Q combustion + Q dynamic ) / l d rho v, and m is the quality of the strip steel entering the continuous annealing unit in perunit time. The method for obtaining the energy consumption per ton of the steel in the continuous annealing unit provides a theoretical basis for optimizing the continuous annealing unit, saving production capacity and reducing costs.

Description

technical field [0001] The invention relates to the technical field of energy consumption optimization of a continuous annealing unit, in particular to a method for obtaining energy consumption per ton of steel in a continuous annealing unit furnace area. Background technique [0002] Now China has become the world's largest steel producer, while my country's iron ore imports also rank first. In 2017 alone, the total global crude steel output reached 1.6912 billion tons, of which China's crude steel output was 832 million tons, accounting for 49.7% of the global total, and nearly 50% of the world's iron ore was consumed by my country. As the food of industry, steel is the most widely used metal in human production activities. It has the advantages of high strength, superior mechanical properties, various varieties, rich mineral resources, low cost and easy production. It has been widely used in various fields of life. It is widely used and has become an indispensable strateg...

Problems solved by technology

However, the production line unit contains a lot of process parameters and steel type parameters, and the production process is complicated. A few studies are focused on heat preservation methods and waste heat recovery. There is no research on process parameters, and there is also a lack of a relationship between process parameters and energy consumption. Energy model, so the present invention mainly focuses on the energy relationship between process parameters and energy consumption per ton of steel, and provides a basis for subsequent multi-process parameter optimization work
