Abstract

The invention relates to a sintering automatic burdening system, in particular to a burdening automatic control system based on chemical compositions for sintering plants, which comprises a base automation level L1 and a process automation level L2 to form a two-level control system network, a data communication network, a parameter acquisition and processing device, a proportion setting program and a control calculation mode, wherein the automation level is composed of a standard two-ring Ethernet, a man-machine interface / program controller, a PC server, a central processor of PLC, an engineer working station and a remote input-output station, the control calculation mode comprises a dry proportion calculation mode, a dry proportion rationality check model, a mixture wet proportion calculation model and a mixture wet proportion calculation model. The invention uses a special model to automatically calculate the proportions of all materials, automatically sets and corrects the set values of each material control system. The database of the system continuously tracks the data of the chemical compositions transmitted from the material center computer and corrects the set values on-time when the data changes.

Description

technical field [0001] The invention relates to an automatic batching system for sintering, in particular to an automatic control system for batching according to chemical components in a sintering plant. Background technique [0002] With the development of the iron and steel industry, blast furnaces have higher and higher requirements for the quality of sintered ore. In the relevant national standards, strict requirements are put forward for the technical indicators (chemical composition, physical properties, metallurgical properties) of sintered ore. For example, the technical indicators of the chemical composition of the first grade of sinter are: TFe≥54, FeO<10, basicity (R=CaO / SiO2)≥1.6, S<0.04. Each sintering plant has put forward the management standards for the qualified product rate and first-class product rate of the sintered ore in the factory according to the above-mentioned standards. In the process flow of the sintering plant, the batching production p...
