Abstract
The utility model discloses a kind of long nozzle with the rim of a bowl liner, comprise mouth of a river body (1), the rim of a bowl inwall at described mouth of a river body (1) is equipped with the rim of a bowl liner (2), this rim of a bowl liner (2) is embedded in the rim of a bowl inwall and its outer wall is mutually concordant with the surface of the rim of a bowl inwall.The utility model by being equipped with the rim of a bowl liner on the rim of a bowl inwall of mouth of a river body, the molten steel that this rim of a bowl liner is positioned at this mouth of a river body washes away place and the outer wall of the rim of a bowl liner is mutually concordant with the surface of the rim of a bowl inwall, and this rim of a bowl liner adopts the alumina-carbon material with excellent anti-molten steel performance of flushing, this long nozzle combines with the tapping hole lower end of collector nozzle of ladle, molten steel in ladle is in steel pouring process, flow directly into the rim of a bowl liner place in long nozzle, the rim of a bowl liner is washed away, the setting of this rim of a bowl liner improves the life-span of long nozzle, have the advantages that anti-molten steel performance of flushing is good, the setting of the rim of a bowl liner simultaneously also saves material, reduce cost, therefore be suitable for promoting the use of.
Description
Technical field
The utility model relates to ultra-low-carbon steel casting technique field, the long nozzle with the rim of a bowl liner that specifically a kind of anti-molten steel performance of flushing is good.
Background technology
The ratio of the current iron and steel continuous casting of China is up to more than 98%, and except extremely indivedual steel grade, molten steel is all converted into steel billet by continuous casting by general steel grade.But for some high-performance steel grades, in casting process refractory material select higher standard, ultra-low-carbon steel waters and has cast this problem.Ultra-low-carbon steel have employed special technique in steel-making and refining process, ensure that carbon content is less than 300ppm.This steel has fabulous deep drawability and ductility (the IF steel of as above th century America Amoca Corp exploitation is used for car panel), high-strength tenacity can (as ultra-low-carbon bainite steel, this steel grade can be used for Arctic heavy caliber high pressure oil-gas pipeline), improve (as super-purity ferrite stainless steels) such as the stainless pitting corrosion resistance of conventional ferrite, toughness and processing characteristicies etc.The production process of ultra-low-carbon steel, except doing except a large amount of work in steel-making and external refining, all will be walked towards the direction of carbon-free combination with all refractory materials of steel contacts.In refractory brick, middle guarantor's refractory material for working layer, people make an adjustment, and the long nozzle connecting ladle and tundish is the important step that in addition another prevents carburetting.
When molten steel by ladle to basket pouring time, in order to avoid oxidation and splash, the lower end of the slide gate nozzle of ladle bottom install long nozzle, one end is connected with the lower mouth of a river, the other end insert tundish molten steel in carry out seal protection cast.The Main Function of long nozzle prevents from secondary oxidation of steel from playing improving the quality of steel, reduces the oxidation product of oxidizable element in steel in mouth of a river inwall deposition and extend its service life, improve watering the steel time and reducing the consumption of long nozzle of long nozzle; The long nozzle of current production also has certain distance from the requirement of steel industry.
Summary of the invention
The purpose of this utility model is for existing long nozzle Problems existing, provides the long nozzle with the rim of a bowl liner that a kind of anti-molten steel performance of flushing is good.
The purpose of this utility model solves by the following technical programs:
With a long nozzle for the rim of a bowl liner, comprise mouth of a river body, the rim of a bowl inwall that it is characterized in that described mouth of a river body is equipped with the rim of a bowl liner, this rim of a bowl liner is embedded in the rim of a bowl inwall and its outer wall is mutually concordant with the surface of the rim of a bowl inwall.
The molten steel that described the rim of a bowl liner is positioned at this mouth of a river body washes away place.
Described the rim of a bowl liner is embedded on mould compressing with mouth of a river body one.
Described the rim of a bowl liner adopts alumina-carbon material to make.
The utility model has the following advantages compared to existing technology:
The utility model by being equipped with the rim of a bowl liner on the rim of a bowl inwall of mouth of a river body, the molten steel that this rim of a bowl liner is positioned at this mouth of a river body washes away place and the outer wall of the rim of a bowl liner is mutually concordant with the surface of the rim of a bowl inwall, and this rim of a bowl liner adopts the alumina-carbon material with excellent anti-molten steel performance of flushing, this long nozzle combines with the tapping hole lower end of collector nozzle of ladle, molten steel in ladle is in steel pouring process, flow directly into the rim of a bowl liner place in long nozzle, the rim of a bowl liner is washed away, the setting of this rim of a bowl liner improves the life-span of long nozzle, have anti-molten steel performance of flushing good feature, only this rim of a bowl liner is set in the rim of a bowl portion simultaneously, also save material, reduce cost, therefore be suitable for promoting the use of.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Wherein: 1-mouth of a river body; 2-the rim of a bowl liner.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
As shown in Figure 1: a kind of long nozzle with the rim of a bowl liner, comprise mouth of a river body 1, the rim of a bowl inwall of mouth of a river body 1 is equipped with the rim of a bowl liner 2 adopting alumina-carbon material to make, the molten steel that the rim of a bowl liner 2 is positioned at this mouth of a river body 1 washes away place and is embedded in the rim of a bowl inwall, and the outer wall of the rim of a bowl liner 2 is mutually concordant with the surface of the rim of a bowl inwall.In order to make this long nozzle, by by the rim of a bowl liner 2 molding blank in advance, then being bumped on mould, finally compressingly together with mouth of a river body 1 obtaining above-mentioned long nozzle.
The utility model by being equipped with the rim of a bowl liner 2 on the rim of a bowl inwall of mouth of a river body 1, the molten steel that this rim of a bowl liner 2 is positioned at this mouth of a river body 1 washes away place and the outer wall of the rim of a bowl liner 2 is mutually concordant with the surface of the rim of a bowl inwall, and this rim of a bowl liner 2 adopts the alumina-carbon material with excellent anti-molten steel performance of flushing, this long nozzle combines with the tapping hole lower end of collector nozzle of ladle, molten steel in ladle is in steel pouring process, flow directly into the rim of a bowl liner 2 place in long nozzle, the rim of a bowl liner 2 is washed away, the setting of this rim of a bowl liner 2 improves the life-span of long nozzle, have anti-molten steel performance of flushing good feature, only this rim of a bowl liner 2 is set in the rim of a bowl portion simultaneously, also save material, reduce cost, therefore be suitable for promoting the use of.
Above embodiment is only and technological thought of the present utility model is described, protection domain of the present utility model can not be limited with this, every technological thought according to the utility model proposes, any change that technical scheme basis is done, all falls within the utility model protection domain; The technology that the utility model does not relate to all is realized by prior art.
