[0005] Preferably, both the left and right covers have:

[0006] The frame is formed by enclosing square blanks to create either a left or right cover shape;

[0007] The steel plates are arranged longitudinally inside the frame, and are more densely packed closer to the joint between the left and right covers.

[0008] Stiffening ribs are laid inside the frame and connected to the steel plates;

[0009] A reinforcing plate is placed between the baking hole and the stopper hole for reinforcement and is connected to the corresponding steel plate or stiffening plate.

[0010] The first anchor is installed on the steel plate and the reinforcing plate;

[0011] Castable refractory is poured between the frame and the steel plate, and also poured at the joints using molds.

[0012] Preferably, the hole is a baking hole, used to connect the baking holes of the left and right covers that are staggered, as well as the stopper hole.

[0013] Preferably, the frame has an open joint surface corresponding to the left and right covers, and the stiffening ribs are laid at the joint.

[0014] Preferably, an extension plate is provided on the steel plate corresponding to the joint to enhance the strength of the joint.

[0015] Preferably, a second anchor is provided on the steel plate and the extension plate on one side of the docking point to enhance the strength of the docking point and the arc-shaped opening.

[0016] Compared with the prior art, the beneficial effects of this utility model are: changing the traditional three-part structure of the inner packaging cover to a two-part structure, namely the left cover and the right cover, which simplifies the structure and improves the flexibility of use. By connecting the half holes, the baking hole and the stopper hole are connected in an interlaced manner. Furthermore, the connection part is reinforced by the extension plate, the second anchor, and the stiffener, which increases the wear resistance of the connection part. The reinforcement plate can increase the connection strength between the baking hole and the stopper hole. This utility model has the advantages of simple structure, low cost, and flexible use. It is suitable for various packaging application scenarios, greatly improves the service life of the inner packaging cover, shortens the turnover time of the inner packaging cover, and improves production efficiency.
