КОЛОСНИКОВІ ҐРАТИ АГЛОМЕРАЦІЙНИХ ТА ОБПАЛЮВАЛЬНИХ МАШИН

Abstract

The purpose of the work is to create a grid field system of sintering or firing machines with high operational stability and low resistance. The common designs of grate grates of agglomeration machines are considered. It was established that one of the shortcomings is the parallelism of the contact surfaces of the locks, the spical carriage of the under-rail beams. A new structure of the grate with an angle α of the contact faces of the mouth of the grate lock to the under-grate beam has been developed. This will reduce the transfer of heat load to the spiking trolley by minimizing the area of contact with the under-grill beam, and will increase air access for cooling the under-grill beams. Due to the wedge-shaped forms of the contact surfaces, the material falling into the spaces between the gratings and sub-grating beams has the ability to move in different planes without blocking in the gaps and being removed.
