Segregation distribution method for sintered material

Abstract

The invention relates to the technical field of sintering, particularly to a segregation distribution method for a sintered material. The segregation distribution method comprises the steps that a mixture ore bin is weighed at a first weighing point of the lower end of the mixture ore bin, and first real-time weighing data a is acquired; the mixture ore bin is weighed at a second weighing point of the lower end of the mixture ore bin, and second real-time weighing data b is acquired; residence time Ta of a reciprocal feeder at a first limit material falling point and residence time Tb of the reciprocal feeder at a second limit material falling point are set; an average of the sum of the first real-time weighing data a and the second real-time weighing data b is calculated, when the average is 20% to 30% of the maximum loading weight of the mixture ore bin, segregation control is carried out; the value of a minus b is calculated; if a minus b is smaller than or equal to epsilon, segregation control is carried out according to the current Ta and Tb values; and if a minus b is larger than epsilon, the current Ta or Tb is regulated till a minus b is smaller than or equal to epsilon, and segregation control is carried out according to the corresponding Ta or Tb value. According to the segregation distribution method for the sintered material provided by the invention, quality of a sintered product is improved.

Description

technical field [0001] The invention relates to the technical field of sintering, in particular to a sintering material segregation distribution method. Background technique [0002] In the sintering industry, the distribution system of the sintering machine consists of a shuttle belt conveyor, a mixed material bin, a large and small gate system, a round roller distributor, a multi-roll distributor (or a reflector and a chute). The traditional material distribution control method is mainly to adjust the speed of the multi-roller distributor (or adjust the inclination angle of the chute) to form segregation of the mixed material on the sintered material of the sintering machine trolley to achieve longitudinal segregation, that is, along the height of the material layer The particle size of the mixture gradually becomes coarser from top to bottom, and the distribution of carbon decreases from top to bottom, so as to improve the aerodynamic characteristics and thermal system of...

Problems solved by technology

[0003] The embodiment of the present invention solves the technical problem that the sintering machine is difficult to achieve good lateral segregation in the prior art by providing a sintered material segregation distribution method, and realizes the lateral segregation of the sintered material, so that the sintered material with a large particle size is distributed in the mixed material In the middle of the sintering pile in the ore bin, the air permeability in the middle of the sintering pile is improved, so that the sintering material is evenly sintered and the quality of the sintered product is improved
