The invention discloses a repairing furnace top and repairing method for a collapsed portion of the furnace top of a steel-rolling heating furnace. By adoption of a plastic prefabricated part, the advantages that the temperature and strength in the plastic furnace top are not decreased, the temperature and strength are high, the thermal shock resistance is good, and the stripping resistance is high are maintained; deformation caused by uneven stress of flexibly-hung anchoring bricks is automatically compensated by adoption of the structure that the furnace top is flexibly hung through springs, and the phenomenon that the anchoring bricks are pulled broken is completely eradiated; and a gap between the plastic prefabricated part and the normal furnace top is poured in site. The problems that repairing construction of the collapsed portion of the original furnace top is difficult, and the construction quality cannot be guaranteed easily are solved; the construction difficulty is greatly lowered, and the constru
