Problems solved by technology

In order to prevent rebound, it is necessary to make it easy for the gas to escape from the cheek plate, but the cheek plate is in contact with the pressure roller, so it is difficult to discharge the gas

Abstract

The invention provides a cheek plate of a reduced iron briquetting device, which can effectively discharge the gas generated during processing reduced iron while strengthening the abutting force with the two sides of the pressure roller. The cheek plate of the reduced iron briquetting device, It includes: a fan-shaped cover body, which is respectively arranged on the two sides of a pair of pressure rollers for processing reduced iron, and is used to prevent the reduced iron from leaking from the side space formed by the pressure roller and the pressure roller; the pressure roller abutment part , the pressure roller abutting portion protrudes from the inner edge of the cover portion and abuts against the outside of each pressure roller, thereby maintaining the airtightness of the space between the pressure roller and the pressure roller; and the exhaust portion , the exhaust portion is formed extending along the plate surface of the pressing roller abutting portion, and is used for exhausting gas generated during processing reduced iron.

Description

technical field [0001] The invention relates to a cheek plate, which is arranged on both sides of a pressing roller of a briquetting device, and is used for preventing leakage of reduced iron. Background technique [0002] If the reduced fine iron ore is exposed to the air, it is easily oxidized due to its high reactivity or there is a risk of fire. This reactivity originates from the specific surface area of ​​fine iron ore. When fine iron ore in the hematite form is reduced to magnetite, the crystal structure changes considerably. [0003] Since hematite and magnetite differ greatly in their lattice structures, changes in the crystal structure can lead to volume expansion and a large number of internal cracks. The generation of cracks will increase the specific surface area of ​​the ore and increase the area that may react with the gas, which ultimately helps to increase the reduction rate. [0004] When fine iron ore in the form of limonite is heated above 500°C, it lo...
