Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of iron ditch prefabricated parts, in particular to an amorphous refractory cast iron ditch prefabricated part. Background Art
[0002] During blast furnace ironmaking, molten iron flows through the taphole into the ladle for the next process. The tapholes of large and medium-sized blast furnaces are subjected to thousands to tens of thousands of tons of molten iron daily, resulting in deep grooves forming at the tapholes. These grooves require prompt repair to prevent production disruptions, and damage is frequent.
[0003] The existing technology has the following problems:
[0004] After extensive searching, it was found that Chinese patent publication number: CN202090006U discloses a prefabricated part for the outlet of an iron trough or a slag ditch of a blast furnace, comprising a U-shaped prefabricated part body and an L-shaped insertion section connected to the U-shaped prefabricated part body; a U-shaped reinforcement layer is provided in the U-shaped prefabricated part body, and anchors are connected to the inner and outer walls of the U-shaped reinforcement layer, and a support plate is connected to the upper end of the U-shaped reinforcement layer; based on the U-shaped reinforcement layer, the castable layer cast on the inner wall is the inner layer, and the castable layer cast on the outer wall is the outer layer; the L-shaped insertion section is inserted into the two side walls of the outlet of the iron trough or the slag ditch, and the inner layer of the U-shaped prefabricated part body and the inner wall of the outlet of the iron trough or the slag ditch of the blast furnace are in the same plane. The utility model can improve the service life of the iron trough or the slag ditch, reduce the labor intensity of repair, and reduce the consumption of refractory materials and production costs for repair.
[0005] However, the above patent still has problems that need to be improved during actual use. The most obvious one is that the service life of the iron ditch is increased by providing a reinforcement layer on the iron ditch. However, over time, the high-temperature liquid iron will also cause erosion on it, making maintenance cumbersome and laborious, and inconvenient to replace.
[0006] Therefore, we proposed amorphous refractory casting iron trough prefabricated parts to solve the above-mentioned drawbacks. Utility Model Content
[0007] The utility model aims to solve the shortcomings in the prior art and proposes an amorphous refractory casting iron ditch prefabricated part.

[0011] Preferably, the diameter of the sink is larger than the diameter of the fastening bolt.
[0012] Preferably, the diameter of the plurality of detachable reinforcement plates is smaller than the diameter of the main body of the iron ditch prefabricated component.
