Claims

[Claims for Utility Model Registration] 1. Consists of a base member 10 made of a heat-resistant alloy that is in contact with the top of the inner surface of a skid pipe and fixed by welding, and a button top member 20 that is a sintered block held by the base member. The button top member 20 includes a top plate portion 21 whose upper surface is a contact surface for the heated steel material, a neck portion 22 that hangs down from the top plate portion, and an enlarged diameter bulge portion 23 formed at the lower end of the neck portion. The base member 10 is a combination of two horizontally divided base plate parts 10.1 and 10.2 joined together with the dividing surfaces as mating surfaces, and the base member 10 has the above-mentioned parts inside. The button top member has a cavity 11 in which the enlarged diameter bulging portion 23 is enclosed, and an inwardly projecting edge 12 that surrounds the neck portion 22 of the button top member is formed above the cavity. 20 has a neck portion 22 and an enlarged diameter bulging portion 23 included in the base member 10, and a top plate portion 2.
Reference numeral 1 indicates a skid button for a heating furnace, which is supported on the top surface 13 of a base member. 2. The skid button for a heating furnace according to claim 1, wherein a heat insulating material layer 30 is provided at the contact interface between the button top member 20 and the base member 10. 3. The button top member 20 is a sintered block of Cr-Fe alloy with a Cr content of 50 to 95% by weight, or a sintered block having a mixed structure consisting of the Cr-Fe alloy and ceramic particles. The skid button for a heating furnace according to claim 1 or claim 2.
