Yield increasing and consumption reducing method capable of stably controlling sintering end point

Abstract

The invention discloses a yield increasing and consumption reducing method capable of stably controlling a sintering end point. The method is characterized by comprising the following steps that (1) burdening is conducted in a burdening chamber, a mixture obtained after burdening is completed enters a primary mixer along a belt to be evenly mixed, and the moisture value is supplemented to the target water adding amount in the primary mixer; (2) the mixture evenly mixed in the primary mixer enters a secondary mixer along the belt to be evenly mixed, and the mixture evenly mixed in the secondarymixer is subjected to online moisture measurement on the belt; (3) the mixture evenly mixed in the secondary mixer reaches a machine head of a sintering machine along the belt for distributing, and the thickness of a material layer is controlled to enable the thickness of the material layer to be in accordance with a set value for distribution for a material surface; and (4) after material distribution is completed, ignition is conducted through an igniter to control the combustion speed and the sintering end point temperature, and the coal gas amount is automatically adjusted through a flowadjusting valve, and therefore the sintering end point position is stably controlled. According to the method, through automatic control of the moisture of the sintering mixture, automatic control ofthe thickness of the material layer of the sintering machine and automatic control of the ignition temperature of the sintering machine, the moisture fluctuation of the sintering mixture is within + / -0.2%, the thickness deviation of the material layer of a sintering machine trolley is within + / -5 mm, frequent adjustment of the sintering ignition temperature by a worker in charge of fire is avoided, and stable control of a sintering end point is realized.

Description

technical field [0001] The invention belongs to the technical field of sintering technology, and in particular relates to a method for increasing production and reducing consumption by stably controlling the sintering end point of a sintering machine. Background technique [0002] In the sintering production process of the existing belt-type sintering machine, the control of the sintering end position directly affects the sintering capacity and quality. The front position of the sintering end point will reduce the effective area of ​​the sintering machine, reducing the sintering capacity and the utilization factor of the sintering machine; the rearward position of the sintering end point will result in the incomplete combustion of the sintering mixture on the trolley, and the poor quality of the sintering ore. [0003] The conventional sintering end point position is affected by many factors such as the moisture content of the mixture, the thickness of the cloth, and the ign...
