Abstract

The invention discloses a sintering mixed material heating method and system, and belongs to the technical field of sintering. The heating method is characterized by comprising the following steps that 1, superheated steam with the temperature of 180-220 DEG C in a sintering boiler flue is recycled, and saturated steam of an outer net pipeline is recycled; 2, the superheated steam and the saturated steam are mixed into mixed steam according to the proportion of 1: 2; 3, the mixed steam in the step 2 is subjected to dehydration treatment; and 4, the mixed steam subjected to dehydration treatment in the step 3 is used for heating a mixed material. According to the method and the system, on the premise that a heating source is not additionally arranged, the recycled energy is reasonably utilized, the heating effect on the mixed material can be achieved, the proportion is really optimized, the cost is saved, and the cost is reduced and the efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of sintering, and in particular relates to a method and system for heating a sintering homogeneous material. Background technique [0002] Sintering refers to the traditional process of converting powdery materials into dense bodies. The selection of sintering raw materials, the ratio of raw materials, the performance and operation steps of equipment, and how to adjust the chemical properties of the homogeneous material are all the key points that should be considered in the sintering process. According to the existing technical background and market economy, optimizing the ratio, saving costs, reducing costs and increasing efficiency, and improving sintering output and quality without affecting the traditional production rhythm are the main directions of technology research and development. [0003] Because the temperature of the homogeneous material is relatively low, it is necessary to increase the mater...
