Abstract
The invention discloses an atmosphere furnace. The atmosphere furnace comprises a furnace body, a furnace door and a hearth and is characterized in that a fluorosilicone rubber seal ring is arranged between the furnace door and the furnace body, a water-cooled circulating system is arranged on the furnace door, a heating element is arranged in the hearth, a silicon carbide refractory slab is arranged on the heating element, an air inlet channel is arranged at the top of the hearth, a preheating cavity is arranged on the air inlet channel, and a heating device is arranged in the preheating cavity. According to the invention, the fluorosilicone rubber seal ring is arranged between the furnace door and the furnace body, and as fluorosilicone rubber has high heat resistance, air tightness can be well ensured; the water-cooled circulating system arranged on the furnace door can effectively lower the temperature of the fluorosilicone rubber seal ring and prolong the service life of the fluorosilicone rubber seal ring; as the silicon carbide refractory slab is arranged on the heating element, and temperature is evener through the condition of the silicon carbide refractory slab in the heating process; and as the preheating cavity is arranged on the air inlet channel, air can be preheated.
Description
Technical field
The invention belongs to atmosphere furnace field.
Background technology
Atmosphere furnace needs to be passed through protective gas when heating, therefore requires the air-tightness of whole body of heater relatively
High.Existing atmosphere furnace uses conventional seals circle to seal, it is easy to aging gas leakage.Existing atmosphere furnace does not has
There is preheating device, when being passed through protective gas, in-furnace temperature can be caused to reduce.
Summary of the invention
For the problems referred to above, it is an object of the invention to provide a kind of atmosphere furnace, solve existing atmosphere furnace close
Seal the most aging and logical protective gas and do not preheat the problem causing temperature to reduce.
The technical scheme is that a kind of atmosphere furnace, including body of heater, fire door and burner hearth, its feature exists
In, it being provided with fluorosioloxane rubber sealing ring between described fire door and body of heater, described fire door is provided with Water-cooling circulating
System, is provided with heating element heater, described heating element heater is provided with silicon carbide deck, stove in described burner hearth
Thorax top is provided with inlet channel, and described inlet channel is provided with preheating cavity, arranges in described preheating cavity
There is heater.
The present invention compared with prior art has the advantage that
Fluorosioloxane rubber sealing ring is used, owing to fluorosioloxane rubber has the highest between fire door and the body of heater of the present invention
Thermostability, air-tightness can well be ensured.Fire door is provided with water-cooling circulating system, Ke Yiyou
Effect reduces the temperature of fluorosioloxane rubber sealing ring, extends the life-span of silicone rubber O-ring.Arrange on heating element heater
There is silicon carbide deck, heating process is conducted through silicon carbide deck, more uniform temperature.On inlet channel
It is provided with preheating cavity, gas can be preheated.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
In figure, reference is: 1-body of heater, 2-fire door, 3-burner hearth, 4-fluorosioloxane rubber sealing ring,
5-inlet channel, 6-preheating cavity.
Detailed description of the invention
Embodiment
As it is shown in figure 1, a kind of atmosphere furnace, including body of heater 1, fire door 2 and burner hearth 3.Described fire door 2
And being provided with fluorosioloxane rubber sealing ring 4 between body of heater 1, described fire door 2 is provided with water-cooling circulating system.
Water-cooling circulating system is made up of the circulation pipe being arranged on fire door 2, cistern and circulating pump.Described burner hearth 3
Inside it is provided with heating element heater, described heating element heater is provided with silicon carbide deck, through carbon in heating process
SiClx refractory slab conducts, more uniform temperature.
Burner hearth 3 top is provided with inlet channel 5, and described inlet channel 5 is provided with preheating cavity 6,
Being provided with heater in described preheating cavity 6, heater uses spiral helicine resistance wire, when gas leads to
Out-of-date, just gas can be preheated.
