AI Technical Summary

Technical Problem

The existing belt roaster pellet test methods have large deviations from the temperature changes, duration and wind conditions in the actual production process, resulting in insufficient reference of the test results, making it difficult to accurately simulate the production process of belt roaster pellets.

Method used

By performing cage casting tests on the belt roaster, the mass transfer and heat transfer process of the pellets in actual production are simulated, the parameter curve of the belt roaster is recorded and drawn, chemical analysis, physical performance detection and metallurgical performance detection are carried out, raw material ratio and process parameters are adjusted until the required pellet ore performance indicators are reached.

Benefits of technology

The experimental research conditions that are more in line with the actual production are achieved. The obtained data and recommended process system can be used as the basis for the design and production operation of belt roaster pellet plants. The test method is simple, has strong controllability and high accuracy, and is suitable for industrial promotion and application.

Abstract

The invention provides a process test method for a belt type roasting machine. The invention designs the belt type roasting machine process test method suitable for actual production, the provided test research conditions are more suitable for actual production, and the obtained research data and recommended process system can be used as the basis for design, production and operation of a belt type roasting machine pelletizing plant. The process test method provided by the invention can be directly carried out to obtain a process system and a finished product index; a laboratory simulation belt type roasting machine test can be carried out between pelletizing and a belt type roasting machine cage casting test, and the cage casting test on the belt type roasting machine is carried out after certain basic data is obtained, so that the test workload is reduced, meanwhile, laboratory data is checked and corrected, and the test efficiency is improved. Errors caused by air conditions, temperature and time differences of laboratory tests and actual production are reduced, and finally a more reasonable process system and pellet index basis can be provided for design and production operation and maintenance of a belt type roasting machine pellet factory.
