Pusher-type heating furnace for rod and wire production line hot transporting and hot charging and direct rolling

Abstract

The invention discloses a pusher-type heating furnace for rod and wire production line hot transporting and hot charging and direct rolling, and belongs to the technical field of industrial furnaces.The pusher-type heating furnace comprises a swinging roller way, a hot transporting roller way, a cold blank rack, a transition rack, a furnace-front roller way, a pusher, a buffering baffle, an arc-shaped heat preservation roller way and the like; the swinging roller way is connected with the hot transporting roller way and the arc-shaped heat preservation roller way; the furnace-front roller wayand a furnace bottom beam are connected through the transition rack; the buffering baffle is located at the tail end of the furnace-front roller way; the arc-shaped heat preservation roller way is connected with the swinging roller way and a discharging cantilever roller way in the pusher-type heating furnace; and the discharging cantilever roller way is connected with the arc-shaped heat preservation roller way. The pusher-type heating furnace has three working modes including a direct rolling mode, a hot transporting and hot charging mode and a cold blank charging mode. The pusher-type heating furnace has the advantages that stabilization, coordination, high efficiency and continuity of overall running of the production process are promoted, and the energy conservation and emission reduction potential abilities of a continuous casting blank hot transporting and hot charging and direct rolling technology are fully achieved.

Description

technical field [0001] The invention belongs to the technical field of industrial furnaces, in particular to a pusher type heating furnace suitable for hot feeding, hot charging and direct rolling in a rod and wire production line. Background technique [0002] Continuous casting slab hot charging and direct rolling are a new process and new technology developed by integrating the latest technological achievements in steelmaking, continuous casting and steel rolling in recent years. It promotes the production management of steelmaking-continuous casting-steel rolling The integrated process can achieve comprehensive benefits such as energy saving, consumption reduction, product quality improvement and productivity improvement. According to the information, only using the hot delivery and hot charging process can reduce fuel consumption by 45%, and reduce production costs by about 30-60 yuan / ton. As the steel market continues to slump and major steel mills are fighting for su...
