Reheating furnace for reheating and temperature averaging hot steel stock

摘要

In order economically to the hot steel inventory of reheating, its average temperature value is slightly below required hot forming temperature and only lies, but its edge is clearly colder than mean temperature, to hot-forming temperature, the furnace space of one reheat boiler (2) is divided at least one and reheats region part (6) and an average area fraction (7), burner (38, 46), the inlet-side end portions (45) and flue gas of its outlet side end portion (47) in reheating are underwritten (48) and are arranged, partition sections (6) are divided into area, in order to form a temperature characterisitic (55), it is realized with one maximum temperature in inlet-side end portions (45) and a minimum temperature, it is reheating the outlet side end portion of region part (6) (47).
