Hot rolling is a process of heating a metal material to a temperature higher than the recrystallization temperature and rolling the metal material to form a shaped material or a plate having a specific shape. The metal material is heated to the recrystallization temperature during hot rolling, so that the plasticity of the metal material is higher, the deformation resistance is lower, and the energy consumption of metal deformation is greatly reduced. The hot rolling can reduce the difficulty of the rolling process, improve the tissue compactness of the metal material and improve the processing performance of the metal material.
In order to hot-roll a metal material, the metal material is generally heated by a dedicated heating furnace.

The following detailed description of embodiments of the present application refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are given by way of illustration and explanation only, not limitation.
In the present application, unless otherwise stated, the orientation or positional relationship indicated by the use of the terms of orientation such as "upper and lower" is based on the orientation or positional relationship of the feed mechanism of the walking beam copper ingot gas-fired furnace of the present application when it is actually used. The position and position relation indicated by the position words of 'front' and 'rear' is based on the normal conveying direction of the copper ingot when the feeding mechanism of the stepping copper ingot gas heating furnace and the stepping copper ingot gas heating furnace work normally, wherein the prior direction of conveying the copper ingot is 'front'. The term "transverse" refers to a direction perpendicular to the direction of conveyance of the copper ingot.
In the description of the present application, it is to be noted that, unless otherwise explicitly specified or limited, the terms "disposed" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; they may be connected directly or indirectly through intervening media, or they may be connected through inter-element communication or interaction between two elements. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.
An embodiment of a marching type copper ingot gas heating furnace feed mechanism of this application, as shown in fig. 1-3, including step-by-step feeding unit 1, rectifying unit 2 and centering unit 3 set up on step-by-step feeding unit 1, perhaps the adjacent position of step-by-step feeding unit 1 for to installing copper ingot 4 on step-by-step feeding unit 1 additional through fork truck or driving and rectify and adjust placed in the middle.
The stepping feeding unit 1 comprises a stepping moving beam 11, a stepping fixed beam 12 and a stepping driving assembly 13. The movable stepping beam 11 and the fixed stepping beam 12 are both arranged in a direction parallel to the conveying direction of the copper ingot 4, the movable stepping beam 11 and the fixed stepping beam 12 are arranged at intervals, and generally, the movable stepping beam 11 is arranged between the fixed stepping beams 12. The walking beam 11 is arranged on the stepping driving component 13 or connected with the stepping driving component 13, the stepping driving component 13 is a driving mechanism which can generate the movement in the up-down direction and superpose the movement in the front-back direction, and the walking beam 11 can reciprocate in the up-down direction and the front-back direction under the driving of the stepping driving component 13.
The walking beam 12 is fixedly arranged on the ground or a specific mounting structure. When the stepping movable beam 11 descends under the driving of the stepping driving assembly 13, the height of the stepping movable beam 11 is lower than that of the stepping fixed beam 12, at the moment, the copper ingot 4 is transversely loaded onto the stepping feeding unit 1 through a forklift or a travelling crane, and the stepping fixed beam 12 supports the copper ingot 4. The stepping driving assembly 13 drives the stepping movable beam 11 to ascend, and the height of the stepping movable beam 11 is gradually higher than that of the stepping fixed beam 12, so that the copper ingot leaves the stepping fixed beam 12 and is borne on the stepping movable beam 11; the stepping driving assembly 13 drives the stepping movable beam 11 to move backwards to convey the copper ingot 4 to the next stepping position, at the moment, the stepping driving assembly 13 drives the stepping movable beam 11 to descend, so that the height of the stepping movable beam 11 is gradually lower than that of the stepping fixed beam 12, the copper ingot 4 is re-loaded on the stepping fixed beam 12, and the copper ingot 4 is conveyed to the next stepping position on the stepping fixed beam 12. The stepping drive assembly 13 drives the stepping moving beam 11 to move forward again, and returns to the initial position to prepare for next conveying of the copper ingot 4.
The deviation rectifying unit 2 comprises a deviation rectifying and positioning device 21 and a deviation rectifying and pushing device 22. The deviation-rectifying positioning device 21 is arranged on the stepping fixed beam 12, so that a positioning surface of the deviation-rectifying positioning device 21 is perpendicular to the conveying direction of the stepping feeding unit. The deviation rectifying pushing device 22 can be various devices capable of pushing the copper ingot to move, such as an air cylinder, a hydraulic oil cylinder, an electric push rod and the like, the deviation rectifying pushing device 22 is arranged in front of the deviation rectifying positioning device 21, and the pushing direction of the deviation rectifying pushing device 22 is perpendicular to the positioning surface of the deviation rectifying positioning device 21.
When the copper ingot 4 is loaded on the stepping feeding unit 1, the copper ingot 4 is loaded between the deviation rectifying and positioning device 21 and the deviation rectifying and pushing device 22. Because the loading position of the copper ingot 4 is manually controlled by an operator, the copper ingot 4 is difficult to be ensured to be positioned at an accurate transverse and central position on the stepping fixed beam 12, and the deflection of the position of the copper ingot 4 is inevitable. After the copper ingot 4 is loaded on the stepping fixed beam 12, the deviation rectifying and pushing device 22 is started to push the copper ingot 4 to a position close to the positioning surface of the deviation rectifying and positioning device 21, so that the copper ingot 4 can be conveniently adjusted to be in a state perpendicular to the conveying direction, and the deviation rectification of the position of the copper ingot 4 is completed. Because the pushing direction of the deviation-correcting pushing device 22 is parallel to the length direction of the stepping fixed beam 12, under the pushing of the deviation-correcting pushing device 22, the copper ingot 4 slides along the length direction of the stepping fixed beam 12, the sliding resistance is small, and the stepping fixed beam 12 usually does not scratch the copper ingot 4. In the conveying process of the copper ingot 4, the stepping movable beam 11 firstly lifts the height of the copper ingot 4, and the height of the copper ingot 4 can be easily higher than the deviation-correcting positioning device 21 by controlling the height of the deviation-correcting positioning device 21, so that the deviation-correcting positioning device 21 does not hinder the conveying of the copper ingot 4.
The centering unit 3 includes a centering detection device and a centering roller assembly 31. The detection device placed in the middle can choose for use various devices that can detect 4 centering states of copper ingot, and the centering state of 4 copper ingot of state placed in the middle can detect through the position that detects copper ingot both ends.
