[0002] Refractory bricks, also known as firebricks, are refractory materials of specific shapes and sizes, made from refractory clay or other refractory raw materials. Primarily used in smelting furnaces, they can withstand temperatures of 1580°C to 1770°C. Based on the manufacturing process, they can be categorized as fired bricks, unfired bricks, fused bricks (cast bricks), and refractory insulating bricks. Based on shape and size, they can be divided into standard bricks, ordinary bricks, and special-shaped bricks. Standard bricks are directly formed using presses using standard molds, enabling large batch sizes and high production efficiency.

[0003] At present, due to the special location of the ventilation area on the coke oven, the refractory silica bricks laid on it are special-shaped bricks, such as the one shown in the figure. The characteristics of this special-shaped silica brick are: there is a rectangular step hole a set through the center, and a step hole b connected to the rectangular step hole a and with an inclined side. The surface has a concave semicircular groove c, and the other side has a rectangular step d in the middle, as well as a strip-shaped protrusion e corresponding to the groove c. There are also grooves c and strip-shaped protrusions e on both sides, and there are notches f, g, and h around the edges. Different notch positions are also provided with chamfer structures of different sizes. Due to its complex structure, traditional standard molds can no longer realize the production of this special-shaped silica brick. Therefore, a brick pressing mold for special-shaped silica bricks is urgently needed to solve the above problems. Utility Model Content
