Andalusite Anchor Refractory Brick for Electric Arc Furnace
The Description:
Anchoring bricks, hanging bricks and anchoring parts are mainly used for anchoring castables. It is necessary to solve the problem that the existing anchor brick has poor positioning and easy to change position during construction. The utility model has the shape of a cylinder, an annular groove is arranged at an interval on the cylinder, a pin shaft hole is provided at one end of the cylinder, and the improvement point is that a groove is added at the bottom of the end where the pin shaft hole is located, and the groove is connected with the pin shaft hole and is located on the same vertical plane, the groove section is consistent with the fixing hook, wrapped on the anchoring hook, and the groove section can be U-shaped. The utility model overcomes the defect of poor positioning of the existing anchor brick. When the anchor brick of the structure is used to build the heating furnace, the connection strength between the light refractory brick wall and the heavy casting body is high, the casting body is good, the structure strength of the furnace wall is high, and the furnace wall is not easy to appear the phenomenon of falling block burning loss during the use of the heating furnace, which can ensure the thermal insulation performance of the heating furnace, and prolong the service life of the heating furnace. It is suitable to be used as a building component of various heating furnaces.
