The invention discloses a stepping heating furnace for steel rolling. The stepping heating furnace for steel rolling comprises a stepping heating section and a cooling section which are communicated in sequence, wherein the cooling section at least comprises a transmission pipeline (1) communicating with the stepping heating section and a slag flushing pipe (2) communicating with the side wall ofthe transmission pipeline (1), and the water outlet of the slag flushing pipe (2) is a duckbilled pipe nozzle structure. According to the stepping heating furnace for steel rolling, the slag flushingpipe communicates with the side wall of the conveying pipeline, which enable the slag flushing pipe is vertically arranged on the conveying pipeline, and which further enable the water flow in the slag flushing pipe obtain larger kinetic energy to wash and cool the red slag in the transmission pipeline, further, the water outlet of the slag flushing pipe is arranged as the duckbilled pipe nozzlestructure, the kinetic energy of water outlet of the water outlet is further improved through the change of the sectional area, the washing effect is better improved, and the fluency of the washing process is improved.
Description
technical field [0001] The invention relates to the field of rolling equipment, in particular to a walking heating furnace for rolling steel. Background technique [0002] As one of the important production equipment in the steel rolling process, the steel rolling walking heating furnace plays an extremely important role in the steel rolling production process. It mainly includes a heating section and a cooling section, and while the water flow of the slag flushing pipe in the cooling section washes away the scale, it also needs to cool down, impact and beat the red slag. With the arrival of the season, the temperature is getting higher and higher. When the red slag comes down from the slag leak of the heating furnace, a large amount of water is needed to cool it down, and the slag washing water has lost its kinetic energy when it comes out of the ordinary nozzle. The red slag concentrates in contact with water instead of dispersing and contacts with water. As a result, th...
