Abstract
The utility model provides a heat-resisting slide block of a steel rolling heating furnace. The heat-resisting slide block is provided with a semi-slot which transversely runs through the upper part of the heat-resisting slide block and is provided with a circular through hole on the lower part, wherein the lower end face of the slide block is an arc-shaped face, the radius of the slide block is equal to the outer diameter of a longitudinal water pipe, and the included angle between two side faces of the arc-shaped face is 90 degrees. According to the heat-resisting slide block provided by the utility model, the semi-slot is arranged, so that the longitudinal expansibility inside the heat-resisting slide block can be effectively eliminated to prevent the longitudinal water pipe from being cracked due to the longitudinal expansibility inside the heat-resisting slide block. Meanwhile, the arc-shaped face on the lower end face can be seamlessly attached to the longitudinal water pipe and the 90-degree included angle between two side faces forms a welding fillet weld to strengthen heat transfer of the heat-resisting slide block to the longitudinal water pipe, so that the temperature of the heat-resisting slide block is effectively reduced, and the longitudinal expansibility generated by the heat-resisting slide block is further reduced to prevent the longitudinal water pipe from being transversely cracked.
