Description

Technical Field

[0001] This utility model relates to the field of castable technology, specifically to a furnace lining refractory castable structure. Background Technology

[0002] Castable refractories, also known as refractory castables, are granular and powdery materials made by adding a certain amount of binder to refractory materials. They have high fluidity and are monolithic refractory materials formed by casting. Compared with other monolithic refractory materials, they have higher binder and moisture content and better fluidity, so castable refractories have a wider range of applications.

[0003] Publication No. CN217005350U discloses a furnace lining refractory castable structure. The connecting plate is attached to the base, sealing ring, protective sleeve, and the outer side of the casting plate. The connecting plate can firmly and tightly connect the base, sealing ring, protective sleeve, and casting plate. However, this patent still has the following problems in actual use:

[0004] By attaching the connecting plate to the base, sealing ring, protective sleeve, and outer side of the casting plate, the connecting plate can firmly and tightly connect the base, sealing ring, protective sleeve, and casting plate. However, the sealing ring may break after prolonged use at high temperatures. This will prevent the sealing ring from sealing the connection between the first and second refractory castable structures. After the sealing ring breaks, the entire connecting plate needs to be replaced, which will increase the cost to some extent.

[0005] A furnace lining refractory castable structure is proposed to address the problems mentioned above. Utility Model Content
