Small-size sintering cup device and method for performing sintering cup test by using same

Abstract

A small-size sintering cup device and a method for performing a sintering cup test by using same belong to the technical field of steel sintering tests, and are used for effectively reducing edge heat loss in a sintering cup test process and accurately controlling charging. The technical scheme is that a small-size sintering cup is placed in the center of a furnace body; heating tiles are mounted on the circumference of the small-size sintering cup in a surrounding manner, and connected with a sintering cup temperature control device; and a heat insulation power supply, an exhaust gas temperature display instrument, a furnace box temperature display instrument and a sintering negative pressure display instrument are mounted on the furnace body and connected with the sintering cup temperature control device. According to the small-size sintering cup device and the method for performing the sintering cup test by using the same, the heating tiles perform heat compensation for a sintering material in a sintering process, so that the edge heat loss of the sintering material is reduced, and the quality of an edge sintering ore of the sintering cup is improved; a 5 kg-grade sintering cup can be adopted to control the charging amount accurately; and further, the device and the method can simulate the sintering production process accurately, improve the quality of the sintering ore in the sintering cup test, provide accurate processing parameters for production, and have the crucially important effect on production guidance.

Description

technical field [0001] The invention relates to a sintering cup used in a laboratory ore blending test in the iron and steel industry and a method for carrying out a sintering test with the sintering cup, belonging to the technical field of iron and steel sintering tests. Background technique [0002] The sintering cup is one of the most important equipment for ore blending test in the iron and steel industry laboratory. It is divided into ordinary sintering cup and large-scale sintering cup. , the cup height is 700mm, and the material is 100kg each time. The sintering test process is very similar to the sintering production process. Firstly, the batching is carried out according to the calculation results, and the ingredients are manually mixed, and then the drum pelletizer is used to mix and pelletize for the second time, and then the raw fuel after mixing and granulation is put into the sintering cup for Ventilation sintering. The sintering test can simulate the sinteri...

AI Technical Summary

Problems solved by technology

At present, the sintering test has the following deficiencies: First, the heat loss at the edge of the sintering process is large, and the edge effect is serious, resulting in low temperature of the edge material, which makes the quality of the sintered ore at the edge of the sintering cup poor; It is difficult to control accurately, the workload of the experiment is very large, and it needs many people to carry out
