METHOD OF INCREASING uniform temperature in the heating furnace TYPE soaking pits

摘要

1. A method for improving the uniformity of temperature in the heating furnace (200, 300), wherein the at least one heated bar (201, 301) obliquely leans against the inner wall of the heating furnace (200, 300) so that under the ingot (201, 301) between the ingot (201, 301) and the inner wall was a space (205, 305) of triangular cross section, wherein in a furnace supplied fuel, characterized in that at least one tube (230,240, 330, 340) for oxidant with an oxygen content of at least 85% by weight, is placed in the furnace wall so that it is inside the nozzle furnace (200, 300 ), And so that the oxidant can be fed directly into the said space (205, 305) at a rate of at least 100 m / c.2. A method according to claim 1, characterized in that the oxidant is supplied through a tube (330, 340), was reacted with the fuel in this space (305) under the ingot (301), wherein the fuel is supplied into the space (305) through a separate a tube (331, 341) for topliva.3. A method according to claim 1, characterized in that the major portion of the oxidant supplied through a tube (230, 240) is reacted with the CO formed during the fuel in the furnace of incomplete combustion (200) using an oxidant fed into the furnace, which It is not formed a space (205) under the ingot so that the furnace (200), combustion of fuel occurs in two etapa.4. A method according to claim 3, characterized in that the amount of oxidant fed to the furnace (200) is during combustion space (205) under the ingot is reduced so that the total fuel mixture in that part of the furnace, which has not formed a space (205) under ingot became substehiometricheskoy.5. A method according to any one of claims 1-4, characterized in that the oxidant is fed at least with a velocity zvuka.6. The method of
