Problems solved by technology

[0003] At present, for steel rolling heating furnaces, there are fixed beams and movable beam structures, which are generally designed as one billet at a time, and a motion cycle of forward-falling-backward-rising billet step by step. Such a walking cycle cannot increase the motion frequency of the billet, and cannot Improve the tapping rate very well

Abstract

The invention belongs to the technical field of hot working equipment in the iron and steel metallurgy industry, and particularly relates to a stepping type heating furnace with double movable supporting devices for fast-paced production and a machining method of the stepping type heating furnace. The heating furnace comprises a furnace body, a feeding device, a discharging device, a first stepping movable unit and a second stepping movable unit. The first stepping movable unit comprises a first stepping movable supporting device, the second stepping movable unit comprises a second stepping movable supporting device, the feeding device is arranged on the feeding side of the furnace body, the discharging device is arranged on the discharging side of the furnace body, and the first steppingmovable supporting device and the second stepping movable supporting device are arranged in a staggered mode. The two ends of the first stepping movable supporting device and the two ends of the second stepping movable supporting device are in butt joint with the feeding device and the discharging device separately. According to the stepping type heating furnace with the double movable supportingdevices for the fast-paced production and the machining method of the stepping type heating furnace, the supporting devices in the heating furnace are all movable supporting devices, so that a blank is always in an advancing state, and the tapping efficiency is doubled.

Description

Technical field[0001]The present invention belongs to the technical field of heat transfer and heat treatment equipment, and more particularly to a stepping heating furnace and a processing method of fast-paced production of a dual-active support device, generally suitable for rolling pre-heating furnace or heat treatment furnace.Background technique[0002]With the improvement of modern industries and energy-saving, environmental protection, and the useful life of metallurgical thermal processing technology, the amount of iron oxide in the furnace is needed to further improve, and then improve product quality and production indicators. It is required to improve the movement of thermal processing blank movement frequencies and shorten the step time of the blank.[0003]At present, for the rolling steel heating furnace, there is a fixed beam and active beam structure, which is generally designed to be a billet, a forward-drop-back-rising exercise cycle blank step further, such walking cy...
