Zusammenfassung:	The utility model relates to a heating cover buffer device which comprises heating cover struts, springs and sleeves. The number of the heating cover struts is a lot, the heating cover struts are evenly distributed on the circumference of a furnace table of a cover furnace, and the sleeves are supported by the springs and sleeve the outer sides of the heating cover struts. The springs are compression springs and are placed in the heating cover struts, the heights of the springs after the installation of the sleeves are 1.2-1.5 times the heights of the heating cover struts, and the minimum heights of the springs are smaller than those of the heating cover struts. Compared with the prior art, the heating cover buffer device has the advantages of achieving a buffer function when used for installing a heating cover on the cover furnace, protecting internal fireproof materials and sealing knife structures and prolonging service lives of devices.
