Sintering machine residual heat monitoring and adjusting method

Abstract

The invention discloses a sintering machine residual heat monitoring and adjusting method. The sintering machine residual heat monitoring and adjusting method comprises the following steps: step 1, an acquisition device is arranged; step 2, during sintering, the temperature of each acquisition device in the sintering process is recorded, the environment temperature of a sintering machine is recorded as T<E>, the temperature below a sintering trolley fire grate is recorded as T, and the temperature of a sintering flue is recorded as T<D>; the flue gas flow of each acquisition device in the sintering process is recorded, the flue gas flow below a sintering trolley fire grate is recorded as V, and the flue gas flow of the sintering flue is recorded as V<D>; and the sintering flue gas atmosphere composition is recorded; step 3, the residual heat retention rate of the sintering machine body is calculated according to the data collected in the step 2; and step 4, field personnel is guided to adjust production parameters according to the residual heat retention rate of the sintering machine. According to the sintering machine residual heat monitoring and adjusting method, monitoring and early warning can be performed on the sintering machine body residual heat in real time, field operators are guided in time to adjust production parameters and replace or maintain equipment; the sintering machine body residual heat is improved, enterprise production energy consumption is reduced, and considerable additional benefits are created.

Description

technical field [0001] The present application relates to the technical field of sintering production, in particular to a method for monitoring and adjusting waste heat of a sintering machine. Background technique [0002] In my country, sintering is one of the main means of iron ore fines enrichment and agglomeration, and is an important part of the entire iron and steel production process. The amount of material handled in the sintering production process ranks second in the entire iron and steel joint production process, second only to blast furnace smelting, and is one of the processes with the largest material flow and energy flow in the modern iron and steel manufacturing process. Therefore, reducing the energy consumption of the sintering process is an important way to reduce the cost of sintering ore. [0003] The residual heat of sinter body is closely related to the quality of sinter. The residual heat of the body in the sintering material layer is relatively hig...

Problems solved by technology

However, since this invention is based on the oxygen concentration, during the sintering process, the fuel structure in the mixture, the distribution method, and the oxidation of sulfides and nitrogen oxides will all affect the change of the oxygen concentration in the sintering flue gas, which will easily lead to a lot of testing results.
