Description
Technical field
This utility model belongs to metallurgical continuous casting field, is specifically related to a kind of online apparatus for baking of continuous casting tundish submerged nozzle.
Background technology
In continuous casting production process, submersed nozzle must toast before use, and the quality of its cured effect directly affects opening of continuous casting and waters, and the effect in terms of guarantee continuous casting production is extremely critical.
At present, the submersed nozzle roasting of my company uses fixed baking box to toast, and baking air-flow up toasts from bottom, the mouth of a river, toasts from outside to inside.It is uneven that this method is toasted, and effect is undesirable, and gas consumption is big, and gas utilization factor is low, and, baking box is distant from tundish, needs a dead lift every time, easily collide with and cause local to fall block, directly result in time serious to open and water, seriously govern continuous casting billet organization of production.
Therefore, for ensureing that continuous casting produces smoothly, a kind of online apparatus for baking of continuous casting tundish submerged nozzle of exploitation is the most necessary.
Summary of the invention
The purpose of this utility model is to overcome present in above-mentioned prior art toasts the shortcomings such as gas utilization factor is low in uneven and baking process and provides a kind of and need not additionally to increase Special baking baking box and the low online apparatus for baking of continuous casting tundish submerged nozzle of production cost.
The technical solution of the utility model is achieved in that a kind of online apparatus for baking of continuous casting tundish submerged nozzle, including tundish, submersed nozzle, baking barrel and supporting plate, described submersed nozzle is arranged on the center below described tundish, and submersed nozzle is connected with tundish；The lower section of described tundish arranges two symmetrically arranged hooks, and described baking barrel arranges two handrails, and described handrail is correspondingly arranged with described baking barrel, and described handrail is suspended on described hook；Described baking barrel includes cylinder, and cylinder upper end is uncovered, lower end closed, and described submersed nozzle stretches into described inner barrel；Described baking barrel is vertically set on described supporting plate in the way of on-fixed connection.
The lower end of described baking barrel arranges air draft pipe, arranges compressed air valve in described air draft pipe.
Described baking barrel also includes the heat-insulation layer being arranged on inner barrel, and described heat-insulation layer material is aluminosilicate fiber, and its thickness is 10 ~ 50mm.
The cylinder of described baking barrel is steel, and its sidewall thickness is 1 ~ 3mm, and bottom thickness is 5 ~ 15mm.
The lower end of described baking barrel is provided with observation port, and described observation port is shaped as rectangle, its a length of 40 ~ 100mm, and height is 50 ~ 120mm.
The good effect that the technical solution of the utility model produces is as follows: online apparatus for baking simple in construction of the present utility model, simple and practical, it is not necessary to extra increase Special baking baking box, and production cost is low.Mouth of a river homogeneous temperature can be realized be rapidly heated, it is ensured that the baking quality of submersed nozzle, it is ensured that the production direct motion of casting machine, meanwhile, take full advantage of the heat of baking of tundish, saved a large amount of natural gas, it is achieved that cost-effective purpose.

Detailed description of the invention
A kind of online apparatus for baking of continuous casting tundish submerged nozzle, including tundish 1, submersed nozzle 2, baking barrel and supporting plate 7, described submersed nozzle is arranged on the center below described tundish, and submersed nozzle is connected with tundish；The lower section of described tundish arranges two symmetrically arranged hooks 4, and described baking barrel arranges two handrails 5, and described handrail is correspondingly arranged with described baking barrel, and during baking, described handrail is suspended on described hook；Described baking barrel includes cylinder 3, and cylinder upper end is uncovered, lower end closed, and during baking, described submersed nozzle stretches into described inner barrel；When not carrying out toasting work, baking barrel is vertically set on described supporting plate.
The lower end of described baking barrel arranges air draft pipe 6, arranges compressed air valve in described air draft pipe.
Described baking barrel also includes the heat-insulation layer 9 being arranged on inner barrel, and described heat-insulation layer material is aluminosilicate fiber, and its thickness is 10 ~ 50mm.
The cylinder of described baking barrel is steel, and its sidewall thickness is 1 ~ 3mm, and bottom thickness is 5 ~ 15mm.
The lower end of described baking barrel is provided with observation port 8, and described observation port is shaped as rectangle, its a length of 40 ~ 100mm, and height is 50 ~ 120mm.
As it is shown on figure 3, described baking barrel is when off working state, sinking in accident hole 10, and coordinated with supporting plate 7 by handrail 5 fixing, described accident hole is shaped as cuboid, its a length of 5000mm, and width is 800mm, and height is 1000mm.
The baking method of the online apparatus for baking in the present embodiment is as follows:
Step 1: open tundish natural gas valve, valve openings degree is 30%, starts to toast tundish；
Step 2: when tundish temperature reaches 1100 DEG C, submersed nozzle is arranged on the lower end of tundish；
Step 3: baking barrel is promoted at hook from supporting plate, and the handrail of baking barrel is placed in hook, it is adjusted to plumbness, and natural gas valve is opened to maximum, start big fire baking；
Step 4: open the compressed air valve in air draft pipe to maximum, the flame in tundish is guided in submersed nozzle, thus is carried out submersed nozzle roasting preheating by available negative pressure.Being blown into compressed air to toast 1.5-2 hour, by observation port thermometric, the temperature on submersed nozzle surface reaches more than 800 DEG C, can carry out continuous casting production.
When toasting submersed nozzle, the pressure of air draft pipe compressed air is 0.3 ~ 0.6MPa, and gas flow is 6 ~ 10m3/h。
In sum, this utility model solves a difficult problem for submersed nozzle roasting, at tundish bottom, online apparatus for baking is installed, submersed nozzle Quick uniform can be realized and reach baking temperature, simple to operate, the consumption energy is few, avoid a dead lift process collide with cause the production accidents such as block, it is not necessary to operator's distance carry, reduce labor intensity, improve production efficiency, it is ensured that continuous casting produces and is smoothed out.
