Device for preparing hot-press carbon-containing pellet

Abstract

The invention provides a device for preparing a hot-press carbon-containing pellet, belonging to the technical field of metallurgy. The device comprises a fine iron powder heating machine, wherein the fine iron powder heating machine and a coal powder heating machine are connected together in series through a hot wind pipeline; the outlet of the fine iron powder heating machine is connected with the inlet of an iron powder buffer hopper; the outlet of the coal powder heating machine is connected with the inlet of a coal powder buffer hopper; the outlet of the iron powder buffer hopper and theoutlet of the coal powder buffer hopper are respectively connected with a mixing bunker through an iron powder constant feeder and a coal powder constant feeder; the outlet of the mixing bunker is connected with the inlet of a powerful mixer; the outlet of the powerful mixer is connected with the inlet of a high pressure thermal state briquette press through a pipeline; a raw coke oven gas removing system is arranged between the powerful mixer and the high pressure thermal state briquette press; the coal powder heating machine is connected with a hot smoke dedusting system; and a hot closuredtank is arranged under the outlet of the high pressure thermal state briquette press.

Description

technical field [0001] The invention belongs to the technical field of metallurgy, in particular to a device for preparing hot-pressed carbon-containing pellets. Background technique [0002] The main problems of current steel production are long process flow, high energy consumption and heavy environmental load. In the whole system of iron and steel production, the ironmaking system (including sintering, coking, blast furnace) is the most energy-consuming, and it also has a great impact on the environment (mainly CO 2 emission). In 2002, the energy consumption of the ironmaking system accounted for 69.4% of the entire steel industry, CO 2 Emissions accounted for 73.4% of the entire system. Among them, in the process of blast furnace production, its energy consumption and CO 2 The emissions accounted for 49.0% and 53.0% of the entire steel production system, respectively. [0003] With the continuous development of the iron and steel industry, the conditions of raw mate...
