The quality of consumption and product.Existing steel roasting process is that one-to-one baking is directly carried out to ladle using combustor, baking
Process energy consumption is higher, and the coal that each ladle is consumed in baking process is large-minded, entreprise cost heavy load.Existing ladle dries
Roasting equipment is both needed to be used to discharge waste gas, otherwise new thermal source in the reserved certain space of clad mouthful when ladle is toasted
A large amount of heats for rising are discharged with waste gas during cannot be introduced into ladle, waste air, and the heat utilization efficiency after gas-fired is relatively low.
The content of the invention
In view of the shortcomings of the prior art, the present invention is intended to provide a kind of unpowered I. C. jetting formula Ladle-casting apparatus, it can have
Effect reduces gas consumption amount of the iron and steel enterprise when being toasted to ladle, while the heat utilization efficiency of gas-fired is substantially improved.
To achieve these goals, the present invention is adopted the following technical scheme that：
A kind of unpowered I. C. jetting formula Ladle-casting apparatus, including steel ladle cover, it is characterised in that：Heat exchange is provided with steel ladle cover
Room, is evenly distributed with steam vent around steel ladle cover, steam vent is connected with the blast pipe in heat-exchanging chamber, blast pipe with exhaust
Mouth is connected, and air inlet pipe is additionally provided with heat-exchanging chamber, and air inlet pipe is connected with air inlet and combustion-aid air pipe, helps respectively up and down
High-temperature resistant gas pipe is provided with combustion breather pipe, air inlet pipe is arranged in blast pipe, air stream measurement is additionally provided with air inlet
Amount device, is provided with electric control valve and gas flow measurement apparatus, air-flow measurement device and gas flow in Gas Pipe
Measurement apparatus are connected to PLC control devices, and PLC control devices are according to air-flow measurement device and gas flow measurement apparatus
Value of feedback and automatically adjust the opening-closing size of electric control valve and control air-fuel ratio.
The tube wall of air inlet pipe is preferably fold-type tube wall to increase heat exchange area.
High-temperature resistant gas pipe combustion-aid air pipe is deep into ladle, and apart from the preferred 50-200mm of ladle bottom.
The summation of all steam vent cross-sectional areas enters 6-10 times of combustion air position cross-sectional area for combustion-aid air pipe.
The beneficial effects of the present invention are：
The present invention makes full use of heat energy from waste gas to heat combustion air by setting heat recovery system, improves burning effect
Rate, has saved the energy, while controlling air-fuel ratio by PLC control devices so that air-fuel ratio keeps constant in burning so that combustion
Burn more abundant；The summation of all steam vent cross-sectional areas enters the 6-10 of combustion air position cross-sectional area for combustion-aid air pipe
Times, it is ensured that the flow at high speed of combustion air in the case of Blower-free.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
Fig. 2 is air inlet pipe schematic cross-section of the invention.
Specific embodiment
Below with reference to accompanying drawing, the invention will be further described, it is necessary to explanation, the present embodiment is with this technology side
Premised on case, detailed implementation method and specific operating process is given, but protection scope of the present invention is not limited to this reality
Apply example.
As shown in Figure 1, 2, a kind of unpowered I. C. jetting formula Ladle-casting apparatus, including steel ladle cover 13, it is characterised in that：Steel ladle cover
Heat-exchanging chamber 4 is provided with 13, steam vent 12 is evenly distributed with around steel ladle cover 13, in steam vent 12 and heat-exchanging chamber 4
Blast pipe 1 is connected, and blast pipe 1 is connected with exhaust outlet 7, and air inlet pipe 2 is additionally provided with heat-exchanging chamber 4, and air inlet pipe is divided about 2
It is not connected with air inlet 3 and combustion-aid air pipe 11, high-temperature resistant gas pipe 15 is provided with combustion-supporting breather pipe 11, air inlet pipe 2 sets
Put in blast pipe 1, air-flow measurement device 5 is additionally provided with air inlet 3, the He of electric control valve 9 is provided with Gas Pipe 8
Gas flow measurement apparatus 14, air-flow measurement device 5 and gas flow measurement apparatus 14 are connected to PLC control devices, PLC
Control device automatically adjusts electric control valve according to the value of feedback of air-flow measurement device 5 and gas flow measurement apparatus 14
9 opening-closing size controls air-fuel ratio.
The tube wall of air inlet pipe 2 is preferably fold-type tube wall to increase heat exchange area.
The combustion-aid air pipe 11 of high-temperature resistant gas pipe 15 is deep into ladle, and apart from the preferred 50-200mm of ladle bottom.
