Multi-segment of furnace configuration monitoring system based on temperature field analysis

Abstract

The invention relates to a temperature control system of a sintering furnace, in particular to a multiple furnace section configuration monitoring system based on the temperature field analysis. The multiple furnace section configuration monitoring system based on the temperature field analysis comprises a continuous sintering furnace which comprises a degreasing section, a low-temperature sintering section, a high-temperature sintering section and a cold treatment section; each section is provided with at least one sensor and one solid state relay and connected with a temperature control instrument which is connected with an upper computer by a conversion interface; and the upper computer comprises an expert control subsystem and a configuration monitoring subsystem which are connected by ODBC. The multiple furnace section configuration monitoring system based on the temperature field analysis provided by the invention completes the development of the temperature control system of the continuous sintering furnace by the characteristics of non-linear, large lag and strong coupling of the temperature control of the continuous sintering furnace, the temperature field analysis and the configuration software design and the like, thus improving the precision of the temperature control significantly.

Description

technical field [0001] The invention relates to a temperature control system of a sintering furnace, in particular to a multi-furnace section configuration monitoring system based on temperature field analysis. Background technique [0002] The traditional Metal Injection Molding (MIM) process uses a single process such as degreasing, sintering, and cooling. In order to improve product quality and reduce the scrap rate in the sintering process, it is considered to integrate the traditional single process into a comprehensive process. The concept of continuous sintering furnace was born. [0003] The main problem of the sintering furnace is that the temperature control accuracy is not high, so it is difficult to determine a stable production process in the production process. The sintering quality is mainly determined by the uniformity of temperature and the stability of the sintering process. In other words, the temperature control accuracy of the continuous sintering furn...
