Description
Technical field
The utility model relates to a kind of Equipment for Heating Processing, especially relates to a kind of combustion gas heating slow-cooling pit-type furnace.
Background technology
At present, combustion gas hole formula heat treatment furnace commonly used is how similar with car type furnace or bell jar stove, and this stove one-time investment is big, and floor space is big, owing to the frequency of utilization of equipment is not high, makes that the economy of equipment is relatively poor.
The utility model content
The utility model purpose is to provide the combustion gas heating that a kind of cost is low, performance is good slow-cooling pit-type furnace.
For reaching above-mentioned purpose, the utility model adopts following technical scheme, and a kind of combustion gas heating slow-cooling pit-type furnace comprises the body of heater that is made of furnace wall, furnace bottom, bell, and both ends are provided with the operation room that separates with the mould material partition wall in the body of heater, and the mould material partition wall is installed burner; The furnace wall of the adjacent operation room in two ends is followed successively by stock mould layer, waterproof layer, reinforced concrete layer from outside to inside in the body of heater, and other furnace wall is followed successively by stock mould layer, waterproof layer, reinforced concrete layer, thermal insulation layer and the cast bed of material from outside to inside in the body of heater; Furnace bottom is followed successively by waterproof layer, reinforced concrete layer and refractory insulating layer from the bottom to top, and the reinforced concrete layer of furnace wall and furnace bottom adopts integrated poured structure, and heat-resisting concrete buttress is set on the furnace bottom; Furnace wall middle part perforate is provided with buried flue.
Have the passage of heat supply airflow on the buttress with the burner correspondence position.
Bell is arch, is divided into more piece, and the bell inboard is provided with thermal insulation layer.
Because combustion gas heating slow-cooling pit-type furnace of the present utility model adopts furnace wall, the integrated poured structure of furnace bottom, operation room is separated by the mould material partition wall at body of heater two ends, comparing cost with the combustion gas hole formula heat treatment furnace of imitative car type furnace or bell jar stove reduces greatly, has heat-insulating property preferably simultaneously, and easy to operate, long service life.
