Abstract
The utility model relates to a fusion cast lining water gap for steel making, which belongs to the technical field of manufacturing fire-resistant materials for steel making. The utility model comprises a water gap main body (1) and is characterized in that a fusion cast working lining (3) is also inlaid in the water gap main body, and a pouring hole (2) is arranged in the fusion cast working lining. After inorganic materials are mixed, the materials are fused into a liquid state, and then the materials are cast to form under a fusing state. The structural form of organically combing the water gap main body with the fusion cast working lining is adopted by the utility model, the design is reasonable, and the water gap main body and the fusion cast working lining respectively have the characteristics of low price and high practicality and good fire resisting property. The rationalization performance and the application effect of the water gap main body are improved, and the service life is prolonged. The utility model can be used for making upper and lower water gaps of ladles, upper, middle and lower water gaps of pouring boxes, immersion water gaps, long water gaps, metering water gaps, etc. Thus, the utility model can meet the higher requirements on the fire-resistant materials for new metallurgical technology and promote the improvement and innovation of the metallurgical technology, and the quality of metallurgical products can be obviously improved.
Description
Technical field
The utility model relates to a kind of steel-making and serves as a contrast the mouth of a river with founding, belongs to the manufacturing technology field of steel-making with refractory material.
Background technology
The upper and lower mouth of a river of the ladle that existing metallurgy industry is used, the mouth of a river, tundish upper, middle and lower, submersed nozzle, long nozzle, metering nozzle etc., all adopt high-quality inorganic material to be broken into graininess and powdery, under certain proportioning behind whole compression moulding or moulding by casting sintering form, the raw material of these high quality material is artificial purification or synthetic raw material, adds a certain amount of graphite/chromium sand/zircon sand/carborundum etc. as the high-purity corundum material and is made.
Above-mentioned manufacture method is because technological process is longer, and production cost is higher relatively; And the internal structure of finished product is the combination of graininess and powdery, and overall structure is closely knit inadequately, and bond strength is not high between each phase material, influences the physical property such as density, the porosity, elevated temperature strength, the index that deteriorates of mouth of a river material monolithic.
The progress with smelting process continually developed along with new steel grade in the metallurgy industry, particularly high purity steel and high technology content steel grade (as ultra-low-carbon steel and electrical sheet etc.) production technology are had higher requirement to composition, performance, service life and the cost at the mouth of a river, and the existing mouth of a river can not have been satisfied the requirement of metallurgical technology well.
Summary of the invention
The purpose of this utility model provides a kind of reasonable in design, and the steel-making of novel structure serves as a contrast the mouth of a river with founding, can effectively improve the applicable performance and the service life at the mouth of a river, reduces cost, thereby satisfies the requirements at the higher level that existing smelting technology technological progress proposes the mouth of a river.
The utility model comprises mouth of a river body for steel-making serves as a contrast the mouth of a river with founding, it is characterized in that also being embedded with in the body of the mouth of a river founding working lining, is provided with orifice in the founding working lining.
Described founding working lining be with inorganic material mixed after, be melt into liquidly earlier, carry out cast molding in molten condition then and make.Its thickness can be 10～100 millimeters.
The end face of described founding working lining can protrude the end face of mouth of a river body, forms boss.The height of described boss can be 3～30 millimeters.
The end face of described founding working lining can be lower than the end face of mouth of a river body, forms groove.The degree of depth of described groove can be 3～30 millimeters.
Described founding working lining can be spliced by 2～6 circular arc working linings.
The material of described founding working lining can be a magnesia system, magnesium zirconium system, magnalium system, magnalium chromium system, magnesium chromium system, magnesium calcium system, magnesium calcium aluminium system, zirconia system, fused alumina zirconia system, zirconium mullite system, corundum system, pink fused alumina system, titanium corundum system, aluminium silicon system, the mixture of any one or more of silica series refractory material.
The utility model adopts mouth of a river body and founding work to be lined with the version of machine combination, reasonable in design, inexpensive practicality of mouth of a river body and the good characteristic separately of founding working lining fire resistance have been brought into play preferably, and casting technology is applied to the manufacturing of mouth of a river working lining, can bring into play the intrinsic excellent properties of the interior various materials of refractory material effectively also organically combines excellent properties separately, make the founding working lining have the elevated temperature strength height, characteristics such as erosion-resisting characteristics and fire resistance are good, the physicochemical property and the suitable effect at the mouth of a river have been improved, prolonged service life, it is higher to have solved the production cost that sintering forms behind existing employing compression moulding or the moulding by casting the mouth of a river exists, physicochemical property is relatively poor, problems such as service life is short.
The utility model can be used for making the upper and lower mouth of a river of ladle and the mouth of a river, tundish upper, middle and lower, submersed nozzle, long nozzle, metering nozzle etc., can satisfy the requirements at the higher level of metallurgical new technology to refractory material, promote the progress and the innovation of metallurgical technology, and obviously improve the quality of metallurgic product.
