Description
Technical Field
The utility model relates to a heating furnace equipment technical field, concretely relates to heating furnace device of accurate accuse temperature.
Background
Furnace gas temperature measurement is an important link of metal heat treatment, and accurate temperature control can be realized only through accurate temperature measurement. The gas furnace has a plurality of zones (generally 6 zones), each zone having 4 burners, distributed on both sides of the furnace, two burners on each side. When the temperature is raised, the burner is ignited, the gas near the burner is heated by adjusting the gas flow, then the gas is driven to flow by the circulating fan, hot air is blown to the ingot from the bottom of the furnace, and the air after the ingot is cooled (the temperature of the ingot is lower than that of the hot air, and after heat exchange, the temperature of the air leaving the ingot is always lower than that of the air blown to the ingot) is continuously sent back to the burner by the circulating fan for heating. Thus, the temperature of the metal ingot is continuously increased by the continuous circulation of the hot air. The temperature in the hearth can meet the requirement of metal heat treatment, and the key is temperature measurement and temperature control. In the existing push type heating furnace, an inlet furnace gas temperature measuring point is arranged right below the middle of the nozzles of two hot burners, the two burners are controlled to ignite and extinguish at the same time, the gas temperature measured by a thermocouple is accurate under ideal conditions for the gas with the same flow. However, after the heating furnace is used for a period of time, due to the change of working conditions, two burners on each side cannot work simultaneously, or one burner fails, frequent flameout alarm is performed, or the inside of the air valve is too dirty and blocked, and the flames of the two burners are inconsistent. The heating air is not uniform in heat, and in order to reach the set temperature under the condition that one burner is insufficient in heat supply, the other normal burner is bound to increase the supply of fuel gas and increase the heat supply. Thus leading to ingots in different areas, some of which have not reached the desired temperature, and some of which over-burn due to absorbing too much heat, resulting in product scrap.
