Bogie hearth furnace capable of automatically evening temperature

Abstract

The invention discloses a bogie hearth furnace capable of automatically evening temperature. The bogie hearth furnace capable of automatically evening the temperature comprises a hearth, a furnace door and a bogie, wherein the bogie is positioned at the bottom of the hearth; the furnace door is positioned at an opening of the hearth to close the bogie inside the hearth; a smoke exhaust flue is arranged on the tail part of the hearth; the bogie hearth furnace capable of automatically evening the temperature further comprises fuel gas burners and a blower; holes are formed on the two sides of the bottom of the hearth at intervals in a staggered way; the fuel gas burners are fixed inside the holes respectively; and the blower communicates the fuel gas burners in parallel through wind pipes. The bogie hearth furnace capable of automatically evening the temperature has the advantages of uniform heating, easy temperature control, achievement of an automatic temperature evening aim, great reduction in manufacturing cost, long service life and reduction in heat loss.

Description

technical field [0001] The present invention relates to the technical field of bogie furnaces, and more particularly to the technical field of bogie furnaces for heat treatment. Background technique [0002] Generally, the trolley furnace for heat treatment is mainly operated in the form of electric heating. The use of electric heating is to use radiation to heat the workpiece. The advantages are that the heating is relatively uniform, the heating temperature is well controlled, and accurate temperature control can be achieved. , the disadvantage is that the investment is large, and it needs to be equipped with power facilities such as transformers required for power consumption. At the same time, heating with electricity requires higher heating costs than heating with natural gas or liquefied petroleum gas. The heating time is long, and the high power of electric heating is limited, which is not conducive to market competition and does not conform to the national policy ori...

Problems solved by technology

[0002] Generally, the trolley furnace for heat treatment is mainly operated in the form of electric heating. The use of electric heating means that the workpiece is heated by radiation. The advantage is that the heating is relatively uniform, the heating temperature is easy to control, and accurate temperature control can be achieved. , its disadvantage is that the investment is large, and it needs to be equipped with transformers and other electrical facilities required for electricity use. At the same time, compared with heating with natural gas or liquefied petroleum gas, the heating cost required is higher. The heating time is long and the high power of electric heating is limited, which is not conducive to market competition and does not conform to the national policy orientation. However, if natural gas or liquefied petroleum gas is used for heating, uneven heating will occur, and the heating temperature will be difficult to control. It is difficult to guarantee the final effect of heat treatment, and as a trolley furnace for heat treatment, the temperature uniformity in the furnace is one of its important indicators. If the temperature uniformity in the furnace cannot be guaranteed, heat treatment cannot be performed. After heat treatment The product must be a waste product. At present, when natural gas or liquefied petroleum gas is used to heat the furnace, a special high-temperature-resistant fan is used to evenly temperature the furnace. This fan is not only expensive, but also works in a high-temperature environment. Short service life, high failure rate, and many impacts on production
