In recent years, along with steel industry is greatly developed, centre job contract is combined by the progress of smelting technique as lining refractories
Close require more and more higher, the development experience of liner in dundish silica heat-insulating plate, coating, spray paint, dry materials, at present should
With relatively broad for coating and dry materials.
Dry materials in use relies on thermograde progressively to sinter to permanent liner from working lining, in working lining hot side shape
Become compact texture, do not have through-wall crack etc. and cause slag to ooze the phenomenon to permanent layer, and the consistency of un-sintered layer is relatively
Low, beneficially tundish insulation；Additionally, dry materials also have convenient construction, turnover flexibly, application safety, easily turn over bag and de-
Bag, the service life of working lining can be improved, reduce the advantages such as refractory material pollution that molten steel is caused, but owing to dry materials is adopted
Take combination system, contact process exists carburetting problem in various degree.
It is good with corrosion resistance that coating has antiscour, and to non-metallic inclusion (the such as Al in molten steel2O3、SiO2
Deng) there is the adsorption i.e. advantage such as low-carbon (LC), cleaning；But coating baking time is longer, generally 2～6 hours, thus cause life
Efficiency is low, energy consumption is high, cost is high for product, if baking time deficiency, causes coating to be combined with permanent liner insecure, occurs peeling off
With burst apart, and due to the requirement of insulation effect, the porosity of tundish paint working lining is relatively big, and the pore of coating is slag
Main thoroughfare with molten steel penetrates into the working lining of resistance to material, increases the slag erosion to coating, and coating also has and is difficult to turn in addition
The shortcomings such as bag, constructional difficulties, turn around time length, baking power consumption height.
Therefore, how to solve working lining construction inconvenience, easy-sintering, be difficult to turn over bag, turn around time length and carburetting problem and be
Urgent problem.
