The laboratory-scale sintering pot test was conducted to ascertain the appropriate ranges of main factors, which would affect the yield and quality of sinter. Fig. 4 shows the main equipment of sintering pot test. The size of sintering pot is Φ 100 mm × 700 mm. A gas hood is on the top of the sintering pot to introduce the mixed gas into …
The maximum static pressure attained in the pot was − 50 mBar. The flow of waste gas can be varied with the help of a damper. A thoroughly granulated sinter mix was used to conduct the trials. The chemical composition of the sinter mix and solid fuel used in the pot test is given in Table 1.
A sinter mix permeability measurement test was developed and used to evaluate two sinter mix blends and two granulation methods. Two permeability cell sizes were also evaluated. The test appears capable of distinguishing between bed characteristics resulting from moisture and mix composition changes.
The equipment for sinter pot tests with flue gas recirculating. The main processes of sintering pot trials are similar with the industrial sintering process. Firstly, the raw materials are well-mixed according to their proportions. Secondly, charging the raw mixture into a drum (Φ 600 mm × 300 mm) for granulating.
The sinter pot test device simulates the sintering production process and can carry out relevant experimental research according to the requirements of industrial production. All the tests are automated, ensuring the accuracy and reproducibility of the test.Production technology issues provide data for technical research such as ratio ...
Benefits. Maintain productivity even with lower quality iron ore and the addition of ultra-fine iron ore concentrates in the sinter mix. Our mixing area upgrade for sinter plants adjusts to raw material changes by maintaining the gas permeability of the sinter bed on the travelling grate. Contact our sales experts.
The procedure for the sinter pot test is as follows. After the equipment is prepared, the raw material blend is manually weighed and fed into the test pot via a high-intensity mixer and a granulation drum. Once the pot has been A finite difference model …
To explore the feasibility of small-scale sintering pot testing, a 'millipot' facility (diameter of . 12. 53 mm and height of 400 mm) was established and used to examine the sintering ... 2.2 Sintering Equipment . 100.

The study involves the development of a 1-Dimensional unsteady-state mathematical model to describe the various physico-chemical phenomena during sintering of iron ore in a …
The sintering process begins with the preparation of a sinter mixture consisting of iron ore fines, fluxes, solid fuel (called bonding agents in Japan) such as coke breeze, and return fines from the sinter plant and blast furnace as well as recycled ferruginous materials from downstream iron and steelmaking processes.
Sinter Testing. This report to the American iron and steel industry marks the completion of a 1949 survey of blast-furnace sinter practice sponsored by the Sub-committee on Agglomeration of Fines of …
After the test, the sinter produced was removed from sinter-pot and its tumbler strength was tested. Tumbler strength of sinter was measured as per ISO 3271/75 to estimate the cold strength. Based on the method introduced in ISO 3271, 15 kg of sinter with the size fraction of 10–40 mm was tumbled in a circular drum at 25 r/min for 200 times.
