The embodiment of the invention provides a high-temperature-resistant grate. The high-temperature-resistant grate is formed by splicing a plurality of prefabricated grate plates. Each prefabricated grate plate is of a plate-shaped structure. Each prefabricated grate plate comprises a plurality of grate holes which are arranged in the vertical direction and penetrate through the upper surface and the lower surface. The high-temperature-resistant grate further comprises one or more stand columns arranged in the vertical direction, and each stand column is of a hollow column structure. The prefabricated grate plates are supported by the stand columns. The bottoms of the stand columns protrude out of the lower surfaces of the prefabricated grate plates. A vent hole is formed in the side wall of each stand column. The high-temperature-resistant grate is made of an inorganic non-metal refractory material. By means of the technical scheme, the problems that a metal grate in an existing hot blast furnace is not resistant to high temperature, and heating medium-temperature air cannot be achieved are solved.
Description
technical field [0001] The invention relates to the technical field of hot blast stoves, in particular to a high-temperature-resistant stove grate, a hot blast stove system and a method for heating medium-temperature wind. Background technique [0002] In the technical field to which the present invention belongs, the blast furnace ironmaking hot blast stove is developing towards the direction of high efficiency, environmental protection, long life, high blast temperature and compact economy. The structure of the hot blast stove for heating cold air includes a regenerative hot blast stove and a direct heating hot blast stove using a partitioned heat exchange method. Since the conventional partitioned heat exchange device cannot work under high temperature conditions (such as above 1000°C), therefore The regenerative hot blast stove is more widely used in high blast temperature and large blast furnace conditions, and usually adopts a vertical structure. The top-fired hot bla...
