Novel furnace door structure of walking beam heating furnace

Abstract

The invention relates to a novel furnace door structure of a walking beam heating furnace, which comprises rectangular vertical beams and rectangular cross beams, wherein the rectangular vertical beams and rectangular cross beams form a rectangular framework. The invention is characterized in that intermediate posts are embedded and distributed in the rectangular framework, the rectangular framework are divided into containing spaces by the intermediate posts, a furnace casing steel block is arranged in each containing space, every two adjacent furnace casing steel blocks are not in contact with each other, and an expansion space is reserved between every two adjacent furnace casing steel blocks. When in use, because the overall structure of the furnace door is composed of the furnace casing steel blocks, each block can be expanded freely in own reserved expansion space when being heated, thereby effectively preventing the overall structure of the furnace door from deformation after being heated and ensuring that the furnace door can smoothly finish charging and discharging operations.

Description

technical field [0001] The invention relates to a furnace door structure of a novel walking heating furnace, which belongs to the technical field of metallurgy. Background technique [0002] In view of the current technology, the high-efficiency and energy-saving walking furnace is used as the heat treatment equipment commonly used in the hot rolling production line. It is a necessary condition for realizing high production capacity, low energy consumption and ensuring product quality in hot rolling production. Looking further, the ingot heated by the walking heating furnace is generally long in length. For the convenience of feeding and discharging, the width of the door of the walking furnace adopting the form of end-in and end-out is also designed to be relatively large. Moreover, the furnace door is an important part of the heating furnace, and its working reliability directly affects the entire heat treatment process of the ingot. [0003] However, most of the furnace ...

AI Technical Summary

Problems solved by technology

[0003] However, most of the furnace doors currently used in the equipment have the defect of severe deformation of the steel structure during the sealing and heating of the ingot, causing the furnace door to fail to complete normal actions when feeding and discharging materials, and the furnace door cannot be closed properly. The furnace is completely sealed, which further affects the hot rolling quality of the ingot
