Abstract

The invention discloses a smelting production system based on a continuous preheating conveyor, which comprises a continuous preheating conveyor. There is a transfer conveying line, which is connected to the converter; the continuous preheating conveyor is divided into a preheating section and a heating section in turn along the conveying direction. The preheating section is equipped with a high-temperature flue gas outlet, and the high-temperature flue gas outlet is connected to a preheating recovery device; a burner is arranged in the heating section, and the burner is connected with an air inlet pipe for supplying combustion-supporting air and a gas inlet pipe for supplying coal gas, and the intake air of the air inlet pipe and the gas inlet pipe is preheated by the preheating recovery device. The present invention starts from the feeding of the smelting production system, the transfer of hot materials after preheating, the uniform distribution of materials and the comprehensive recovery and utilization of energy, which greatly shortens the feeding time, improves the transfer efficiency, and realizes the preheating of high-temperature flue gas Recycling, thereby shortening the smelting time and improving production efficiency.

Description

technical field [0001] The invention relates to the technical field of converter steelmaking, in particular to a smelting production system based on a continuous preheating conveyor. Background technique [0002] At present, converter steelmaking uses cold scrap steel to make steel. After the scrap steel is added to the material basket with a suction cup, the material basket is hoisted by the crane and directly added to the converter for steelmaking. Adding a large amount of cold material at a time takes a long time for smelting, resulting in low production efficiency. The production capacity is very low. [0003] In order to solve this technical problem, the applicant applied for a utility model patent named converter continuous feeding preheating vibrating conveyor on August 2, 2018. The announcement number is CN208562441U, and the following technical solution is disclosed: it is installed on a long support There is a long conveying trough hanging on the top, a vibrator i...
