Description
Technical field
The utility model relates to cylinder body casting fields, and in particular to a kind of continuous casting production with long service life.
Background technique
Tundish is the refractory material containers used in mini-mill steelmaking, receives to pour the steel to get off from ladle first
Then water is assigned in each crystallizer by middle water containing opening again, tundish as metallurgical reaction be improve output of steel and
An important ring for quality.No matter going on smoothly for continuous casting operation, or for guarantee molten steel quality suit the requirements, tundish
Effect be very important
Currently, the mode that continuous casting production is built is generally permanent layer+working lining, working lining is magnesia coating, each
It pours time and (even to draw 7-8 furnace to be one to pour time) after getting off, it is necessary to replace working lining and middle water containing opening, have the following problems:
(1) each, which is poured, time must replace working lining, resistance to material increased costs；
(2) it after working lining is carried out, also to toast, energy consumption is high；
(3) period replaced is long, and about 3 days；
(4) extremely difficult when replacing middle water containing opening, middle back stall brick can be also broken sometimes.
Utility model content
The purpose of this utility model is that: to solve the problems, such as that existing bakie working lining service life is low, provide
A kind of continuous casting production with long service life.
The technical solution adopted in the utility model is as follows:
A kind of continuous casting production with long service life, including tundish ontology, the tundish ontology include permanent layer and
Working lining on the inside of permanent layer is set, and the working lining includes the magnesia carbon brick layer tightly piled up along the inner edge of permanent layer, described
Magnesia carbon brick layer is equipped with multiple groups in step-like, and the size that the magnesia carbon brick layer of inside is located in two groups of adjacent magnesia carbon brick layers, which is less than, to be located at
The size of the magnesia carbon brick layer in outside.
In above scheme, the permanent layer includes connected trapezoidal sections and rectangular section, the thickness of the trapezoidal sections of the permanent layer
Degree is 80mm, rectangular section of permanent layer with a thickness of 50mm.
In above scheme, the magnesia carbon brick layer is piled up using straight brick and arch brick combination, and the arch brick is located at permanent
At the acute angle corners of layer.
In above scheme, seam is carried out using mouth of a river joint cement between the arch brick.
In above scheme, seam is carried out using high temperature resistant Mg matter chamotte or air brick joint filler between the straight brick.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:
1. the utility model is by the setting of working lining, each using the effect of the multiple groups magnesia carbon brick layer of step-like setting
It is a pour time get off after, do not need to change working lining, only need to change middle water-coating port, a tundish can be used continuously 100 times
More than, the service life of tundish greatly improved, while being used in such a way that magnesia carbon brick is piled up, so that after working lining is impaired
It is conveniently replaceable, monolithic or muti-piece magnesia carbon brick is directly replaced after the magnesia carbon brick damage of innermost layer, the replacement mouth of a river is also more square
Just, without worrying to break working lining.
2. the utility model is greater than in such a way that permanent layer is set as trapezoidal sections and rectangular section using the thickness of trapezoidal sections
The mode of rectangular section of thickness improves the service life of tundish.
3. magnesia carbon brick layer is set straight brick by the utility model and arch brick combines the mode piled up, arch brick is arranged
At the acute angle corners of permanent layer, so that working lining is bonded the inner wall of permanent layer completely, molten steel will not be splashed when ensure that casting
In permanent layer, the service life of tundish is more improved.
4. the utility model carries out seam to arch brick by mouth of a river joint cement, being fully sealed for working lining ensure that,
Improve the service life of tundish.
5. the utility model carries out seam to straight brick by high temperature resistant Mg matter chamotte or air brick joint filler, work ensure that
Make being fully sealed for layer, improves the service life of tundish.
