Rod and wire heating furnace achieving flexible matching direct hot loading of casting machine and rolling mill

Abstract

The invention provides a rod and wire heating furnace achieving flexible matching direct hot loading of a casting machine and a rolling mill, and belongs to the technical field of industrial furnaces. The rod and wire heating furnace comprises a cantilever roller bed side-inlet and side-outlet step-type heating furnace body, accessory equipment, a loading end lower smoke exhausting tube, a smoke exhausting flue, a flexible matching loading machine and a suspension furnace-charging type pusher. The flexible matching loading machine is arranged at the end of the cantilever roller bed side-inlet and side-outlet step-type heating furnace body and the end of the accessory equipment, the suspension furnace-charging type pusher is arranged on the end of the cantilever roller bed side-inlet and side-outlet step-type heating furnace body, the end of the accessory equipment and the upper portion of the flexible matching loading machine, and the exhausting tube and the smoke exhausting flue are arranged at the end of the cantilever roller bed side-inlet and side-outlet step-type heating furnace body, the end of the accessory equipment and the lower portion of the flexible matching loading machine. The rod and wire heating furnace has the advantages that the problem that the steel making continuous casting machine and the steel rolling mill are not matched in production speed and production and maintaining system is solved, the hot conveying and hot loading furnace charging rate and hot conveying billet furnace charging temperature can be improved, and energy consumption of the heating furnace is reduced.

Description

technical field [0001] The invention belongs to the technical field of industrial furnaces, and in particular relates to a rod and wire heating furnace for flexible matching and direct hot charging of casting and rolling mills. Background technique [0002] "Energy saving, emission reduction, efficiency enhancement" is the eternal theme of the steel industry. The "steelmaking-continuous casting-rolling mill" integrated production process, which clearly embodies this theme, is more and more commonly used in iron and steel enterprises. At present, this kind of integrated production is used more and more in the production process of rods and wires. In the production process of rods and wires, due to the technical characteristics of the production line, in this type of production line, generally only one heating furnace is configured as the continuous heating furnace. Slab reheating equipment. Therefore, in order to realize the hot delivery and hot charging production process,...

AI Technical Summary

Problems solved by technology

It solves the problems of production cost reduction and production maintenance system mismatch between the steelmaking continuous casting machine and the steel rolling mill. At the same time, it can increase the rate of hot feeding and heating into the furnace and the temperature of the hot feeding billet into the furnace, reducing the energy consumption of the heating furnace.
