Heat direct reduced iron conveyor

Abstract

The invention discloses a heat direct reduced iron conveyor which is characterized in that: a driven sprocket (3) is arranged at the front of a conveyor rack (1), and a driving sprocket (8) is arranged at the back of the conveyor rack (1); a roller track (6) is arranged between the driven sprocket (3) and the driving sprocket (8), and the two sides of a material conveying carriage (4) are respectively connected with chain links (5); a chain formed by the chain links (5) runs on the roller track (6), and upper and lower heat insulation sealing covers (10,17) are fixed on the rack (1); and spring slide block slideway devices are used for sealing edges of the two sides of the upper and lower heat insulation sealing covers (10,17) and the chain links (5) at the two sides. In the heat direct reduced iron conveyor, the heat direct reduced iron is conveyed, and simultaneously, heat direct reduced iron can be insulated from heat and oxygen so as to avoid oxidation, so that the conditions are created for sending the heat direct reduced iron into an electric furnace at a high temperature; and the production cycle is shortened, the productivity is improved, and the energy loss is reduced.

Description

technical field [0001] The invention relates to the technical field of conveying bulk materials, in particular to a thermal direct reduced iron conveyor, which is mainly used for high-temperature transportation of high-temperature thermal direct reduced iron, and during the transportation process, the thermal direct reduced iron Sealed and insulated. Background technique [0002] Direct reduced iron has proven to be an alternative to conventional blast furnace hot metal, and the direct reduction process is a very efficient production process. The development of the direct reduction iron production process started 35 years ago and since then many safe and reliable direct reduction processes have been introduced into steel production. Since the end of 1990s, the production of direct reduced iron has become more and more important in the regional economy. In recent years, the growth rate of global direct reduced iron production has reached 9%, and the output has doubled every...

Problems solved by technology

However, charging hot direct reduced iron into an electric furnace to produce molten steel is not a common technique

[0005] After completion of the reduction process, the DRI is very hot, so that it is very prone to secondary oxidation problems when the DRI is sent from the DRI plant to the steelmaking workshop
