Abstract
The invention relates to a vertical pushing furnace bottom flow guide and ejection system. The flow guide and ejection system is placed at the bottom of the vertical pushing furnace. The furnace bottom is provided with horizontal direction and longitudinal direction which are perpendicular to each other. The longitudinal direction is identical to the ingot conveying direction. Fixed rails for conveying ingots are placed in the longitudinal direction at the furnace bottom. The flow guide and ejection system comprises flow guide channels positioned at the furnace bottom. The flow guide and ejection system also comprises a plurality of flow guide ejection boxes placed in longitudinal direction at the furnace bottom, and a plurality of flow guide ejection holes placed between every two adjacent flow guide ejection boxes respectively. The flow guide channels are communicated with multiple rows of flow guide ejection boxes, which are communicated with the adjacent flow guide ejection holes. Hot wind flows through flow guide channels, flow guide ejection boxes and flow guide ejection hole to be ejected out. The furnace flue gas passes through vertically erected ingots to conduct the heating treatment to the ingots from a vertical section of the ingots, thus making sure the ingot be heated uniformly, and guaranteeing that no overheating or over-burning phenomenon happens to the ingots.
Description
Technical field
The present invention relates to a kind of standing pushes away stove furnace bottom water conservancy diversion spraying system.
Background technology
Verticle-pushing type casting ingot heating stove at present（Referred to as stand and push away stove）Supply mill milling for ingot casting is heated to rolling temperature.Casting
The mode of heating of ingot is by way of with strong convection, high-temperature furnace gas to be transported between ingot casting, thus ingot casting is heated.At present
The runner of mode of heating furnace gas be not controlled by, the skewness of furnace gas, thus it is too high to produce ingot casting local temperature, and its
Its part is also not reaching to the temperature requirement heating.Its problem is：
1 if with the heating of speed faster, the internal temperature of slab ingot and edge non-uniform temperature, and the temperature difference is big, in rolling
Quality problems can be produced；
If 2 ensure edge and inside the temperature difference little it is necessary to reduce firing rate.Rhythm of production lengthens, and productivity ratio will drop
Low.And waste the energy.
The technology commonly used at present is slit injector, and that is, high-temperature furnace gas are blown in stove by gap.At this moment furnace gas once from
After gap of cracking, its flow direction is uncontrolled.Some furnace gases pass through between slab ingot（Effectively furnace gas）And other furnace gases blow to flat
The bottom of ingot, some furnace gases are directly blown onto the corner of slab ingot, and this often causes slab ingot overheated or burning.
Content of the invention
It is to overcome the deficiencies in the prior art to provide a kind of improved vertical to push away stove furnace bottom and lead that the present invention will solve technical problem
Stream spraying system.
For solving above technical problem, the technical solution used in the present invention is：

Even air distribution is realized in degree direction.
Preferably, trapped orbit has two, and workpiece is vertically erected on two trapped orbits.
Further, water conservancy diversion spray box is more than or equal to the width of workpiece along longitudinal length.
Preferably, stand and push away the furnace bottom of stove and be divided into the being located at respectively outside two articles of trapped orbits by two articles of trapped orbits
One subregion and the second subregion and the 3rd subregion being located between two articles of trapped orbits, each water conservancy diversion spout of the 3rd subregion and water conservancy diversion spray
The area of case is corresponding respectively to be more than the first subregion and each water conservancy diversion spout of the second subregion and the area of water conservancy diversion spray box.Because furnace gas follows
In loop systems, maximum pressure drop produces at furnace bottom spraying system, and individual place is due to distance difference, the linear loss of pressure everywhere
Differ, so the size of spray box is also different, the size of the spray box of spraying system and spacing will be according to the distances of runner and along journey
Pressure drop be designed, therefore no matter how ingot casting length thickness can realize consistent dynamic heat exchange characteristic.
Preferably, in the first subregion and the second subregion, little near the water conservancy diversion spout of lateral outer side and the area of water conservancy diversion spray box
In or be equal near the vertical furnace bottom pushing away stove laterally in the middle of water conservancy diversion spout and water conservancy diversion spray box area.
Preferably, the often row water conservancy diversion spout of the first subregion and the second subregion and the setting of water conservancy diversion spray box mirror image.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages：
Provided by the present invention standing pushes away stove furnace bottom water conservancy diversion spraying system, and furnace gas flow direction is regular and easily controlled, furnace gas
Corner or the bottom of slab ingot will not be directly blown onto, furnace gas passes through between the ingot casting erecting, from the facade of ingot casting, ingot casting be carried out
Heat treated, such ingot casting is heated evenly, thus not cause ingot casting overheated or burning phenomenon.
