Description
Technical field
It the utility model is related to continuous casting ancillary equipment technology, more particularly to a kind of submersed nozzle roasting case.
Background technology
Submersed nozzle is that tundish bottom is arranged in continuous casting equipment and inserts pouring below crystallizer molten steel surface
Note refractory sleeve.In the continuous casting operation process of smelting iron and steel, tundish input pours steel before use, need to be under tundish
The functional refractory materials such as the mouth of a river are toasted, and this procedure is to influence continuous casting and open to pour the important of success rate and refractory product service life
One of factor.If tundish lower nozzle baking is bad continuous casting can be caused to hold inwall knot cold steel in mouth of a river when pouring, add to open and pour wadding stream
Probability；Run into hold pour when molten steel overheat height in the case of can also be big and cracked because of thermal stress, once it is cracked
It must change as early as possible, otherwise billet quality is poor, and drying tundish lower nozzle again needs about 1 hour, and this just have impact on steel billet
Quality adds a ton steel refractory consumption simultaneously.
Mouth of a river baking at present is toasted using bareing, and mouth of a river asbestos are simply wrapped, and baking temperature is uneven, and up to not
To use demand.Mouth of a river fracture of root often occurs during use, mouth of a river bottom breaks off the base phenomenon.For such a problem, spy's research and development
Submersed nozzle off-line baking case.
Utility model content
The technical problems to be solved in the utility model is to be directed to above-mentioned the deficiencies in the prior art, there is provided one kind ensures transhipment dress
Put transportation stability, reduce the submersed nozzle roasting case of operating personnel's operation intensity.
In order to solve the above technical problems, technical solution adopted in the utility model is：A kind of submersed nozzle roasting case,
Including casing and switch gate, the cabinets cavity is provided with refractory material, and the casing includes side plate, backboard and bottom plate, the side
Plate bottom is provided with roasting nozzle, and the switch gate is arranged in front of casing, and locking device, institute are provided between the switch gate and casing
State and fixed support is provided with above backboard, the fixed support is provided with two, and side-lower is provided with hook in the backboard.
Preferably, locking device includes being arranged at the revotating card of switch gate sidepiece and is fixedly installed on the card of side plate sidepiece
Frid, the revotating card are engaged with clamping groove plate.
Preferably, switch gate top side top is provided with switch handle, the switch handle is provided with rubber spacer.
Preferably, switch gate is provided with insulation material close to case-side.
Preferably, fixed support is using U-shaped part and is symmetricly set in both sides above backboard, the fixed support thickness
For 10mm.
Preferably, refractory material using castable refractory irrigate into.
It is using beneficial effect caused by above-mentioned technical proposal：The utility model structure design advantages of simple, passes through
Open-air baking is changed to closed baking, seal during submersed nozzle roasting is improved, invasive nozzle can be made in short-term
Between heat up, so as to quickly avoid the burst temperature of resistance to material, ensure to improve the baking temperature of submersed nozzle in a short time, carry
The high stability of resistance to material, and ensure that temperature is uniform, so as to improve the service life of submersed nozzle, avoid because of immersion water
Mouth cured effect is bad, causes the generation for frequently changing submersed nozzle and production disruption accident, improves submersed nozzle roasting
Efficiency, there is greatly promotional value.
