Abstract
The utility model discloses a whole crucible of prefabricated formula of compound silica wire stone, characterized by adopt white corundum, electric smelting mullite, corundum powder, materials such as zircon and silica wire stone powder are with crucible prefabrication shaping, and the crucible internal surface is the ball end cylindricality, and the surface is cylindrical. According to the utility model discloses prefabricated crucible includes the acidity of 0.3 ton to 5 tons, basicity and neutral crucible, uses the heat to reach more than 40 stoves, and factor of safety improves greatly, shortens process cycle greatly to reduce raw and other materials expense by a wide margin.
Description
The utility model relates to a kind of crucible, specifically a kind of furnace lining that is used to melt the line frequency furnace of molten steel.
The furnace lining of existing line frequency furnace generally is to use field by using quartz sand, magnesia, electric smelting Al
2O
3, adding binding agent such as pink fused alumina sand makes and forms, through oven dry, sintering forms crucible.The crucible out-of-shape that make at the scene, scale error is bigger, generally mostly is flat, and service life is short, and the shortest 2-3 stove just punctures to be scrapped, and the longest life-span also has only the 20-30 stove.For stove more than 0.5 ton, crucible is blasted when puncturing easily, and the safety in production of personal safety and factory is all caused very big prestige association.In addition, the scene is made crucible and is made the process period lengthening.
The purpose of this utility model is that the whole crucible of standard is given in one of design, reduces production costs the service life of improving crucible, reduces process period.
The utility model compound sillimanite gives the whole crucible of standard and is achieved in that employing white fused alumina, electrofused mullite, schmigel, zircon and sillimanite powder give crucible and make shape, and the inner surface of crucible is a spherical bottom-column shape, outer surface is cylindrical, and there are a circular step, shoulder height h in the crucible upper edge
1Be the 15-20 millimeter, the thickness h at the bottom of the inner surface ball at the bottom of the outer surface post
2Be the 70-160 millimeter, the radius R at the bottom of the inner surface ball is the 145-430 millimeter, and crucible whole height H is the 690-1140 millimeter, and the cylinder thickness D of crucible cylindrical section is the 80-200 millimeter.
The utility model compound sillimanite gives the whole crucible of standard, can bring up to more than 40 stoves its service life, and safety coefficient improves greatly, and the raw material expense of each crucible is saved 1000-3000 yuan, owing to adopt and give the standard manufacture method, shortened process period greatly, saved time.The utility model can give acidity, alkalescence and the neutral crucible of making shape 0.3-5 ton.
Fig. 1 gives the section of structure of the whole crucible of standard for the utility model.
Embodiment 1:
0.3 ton gives the whole crucible of standard, R is 145 millimeters, and H is 690 millimeters, h
