Example Embodiment

[0023] A new type of walking furnace door structure, such as Figure 1~4 As shown, it includes a rectangular vertical beam 1 and a rectangular cross beam 2. The rectangular vertical beam 1 and the rectangular cross beam 2 constitute a rectangular framework. The special feature is that the rectangular framework is embedded and distributed with middle columns 3, rectangular frameworks, and middle columns. The three divisions constitute an accommodating space, and the furnace skin steel plate blocks 4 are arranged in the accommodating space. The adjacent furnace skin steel plates 4 do not contact each other, and form a reserved expansion space 9 between each other. Further integration figure 1 From a point of view, both ends of the rectangular vertical beam 1 are provided with connecting plates 5, and both ends of the rectangular cross beam 2 are connected with the corresponding connecting plates 5 to form a rectangular frame.

[0024] Specifically, the bottom surface of the 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 ...
