Abstract

The invention relates to the technical field of industrial furnaces, in particular to a slag discharging system and method for a roller hearth type tunnel heating furnace. The system comprises slag discharging chutes and a conveying device, the slag discharging chutes and slag discharging openings are arranged in a one-to-one correspondence mode, one end of each slag discharging chute is operably in butt joint with the corresponding slag discharging opening, and the other end of each slag discharging chute extends downwards in the vertical direction; and the conveying device operably moves below the N slag discharging openings, a slag hopper is arranged on the conveying device, and the slag hopper selectively communicates with the other end of any slag discharging chute. According to the slag discharging and conveying system for the roller hearth type tunnel heating furnace, manual operation is replaced by intelligent equipment, labor force is liberated, and the production cost of enterprises is reduced.

Description

technical field [0001] The invention relates to the technical field of industrial furnaces, in particular to a slag discharge system and method for a roller hearth tunnel heating furnace. Background technique [0002] In the future, the development trend of my country's iron and steel will definitely focus on the direction of "green" and "intelligent". Through intelligent production, intelligent equipment, intelligent operation management, and intelligent business decision-making, the closed-loop production and operation of the whole process of iron and steel production will be realized. Management is the common goal of all steel mills. [0003] In the prior art, the slag discharge, slag removal, and slag transportation at the bottom of the roller hearth tunnel heating furnace are all manual and regular operations: the on-site operators manually open the slagging furnace door according to the production status or slagging system, and the temperature is about 800 °C The iron ...
