Abstract
The invention provides a ladle and a ladle erosion resistant method. The ladle comprises a steel plate, wherein the steel plate is positioned in a position where a flushing point is generated when molten steel enters the ladle, so as to prevent the ladle from being eroded by the molten steel. According to the ladle and the ladle erosion resistant method, the ladle erosion caused by the molten steel can be effectively reduced, and the service life of the ladle can be prolonged.
Description
Technical field
The present invention relates to a kind of ladle and ladle erosion resistant method.
Background technology
The intermediate link that external refining is produced as converter and continuous casting, play improve output, ensure the quality of products, the effect of purify hot metal and modifying ingredients.Therefore, will provide the molten steel that chemical composition, gas content and field trash are qualified aborning, must carry out external refining, whole smelting process is all using ladle as basic container, and therefore the production of ladle to clean steel is significant.
Ladle lining is had an impact by the cleanliness factor of different modes to steel: (1) ladle slag line place liquid oxygen compound (slag) is to the chemical erosion of refractory material, once there is chemical erosion, the mechanical strength at this position and refractoriness all can degradations; (2) refractory material contacts the rear mechanical erosion produced with molten steel, lining body cracking can be caused to the mechanical erosion (turbulent flow is more serious than laminar flow abrasion) of ladle lining body and strong thermal and mechanical stress when ladle poured into by molten steel, for the ladle adopting the electric furnace of eccentric bottom tapping to use, molten steel has the greatest impact to positions such as bag end molten steel impact zone and the nozzle assemblies that flows through.Chemical erosion and mechanical erosion all can crack, and refractory material is involved in molten steel formed be mingled with, molten steel is polluted.
At present, research emphasis is placed on ladle in the research of the Wear mechanism of refractory material by most of iron and steel enterprise, and start with in all many-sides such as process for making, new material, brick-building art, scientific managements, realize the safe operation of ladle and reduce refractory consumption, but owing to bringing certain difficulty to current technology, again or cost is higher, produce little effect.
Therefore, a kind of method reducing ladle simply and effectively and corrode is needed.
Summary of the invention
In order to overcome the problems referred to above of the prior art, the invention provides a kind of ladle, described ladle comprises steel plate, and described steel plate is positioned at the position washed away a little produced when molten steel enters ladle, corrodes ladle to prevent molten steel.
Preferably, the thickness of described steel plate is 5mm ~ 8mm.Described steel plate is alloy-steel plate, and the composition of described alloy-steel plate is determined according to the composition of the composition of molten steel and steel billet to be manufactured.
Preferably, the inside of ladle is wrapped up in or is partly wrapped up in by described steel plate entirely.
In addition, the invention provides a kind of erosion resistant method of ladle, steel plate is placed in the inside that described erosion resistant method is included in ladle, and described steel plate is positioned at the position washed away a little produced when molten steel enters ladle, corrodes ladle to prevent molten steel.
According to ladle of the present invention and erosion resistant method thereof, effectively can reduce the erosion of molten steel to ladle, extend the service life of ladle.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, the features and advantages of the present invention will become clearly: in the accompanying drawings:
Fig. 1 is the schematic diagram according to ladle erosion resistant method of the present invention.
Detailed description of the invention
Hereinafter, exemplary embodiment of the present invention will be described in detail.
Fig. 1 shows the schematic diagram according to ladle erosion resistant method of the present invention.Known with reference to Fig. 1, ladle 4 according to the present invention comprises the steel plate 5 of the inside being positioned at ladle 4, wherein, steel plate 5 be arranged in when molten steel 2 enters ladle 4 wash away a little 3 position, wash away to prevent molten steel 2 pairs of ladles 4 generations.
Particularly, when converter 1 starts to put steel, first molten steel 2 impacts steel plate 5, and now turbulent flow occurs molten steel 2 in ladle 4, and mechanical erosion is the most serious, but due to the protection of steel plate 5, effectively reduces the mechanical erosion effect of molten steel 2 pairs of ladles 4.
In the present invention, the thickness of steel plate 5 can determine according to the tap of converter 1, when the tap of converter 1 is large, can adopt thicker steel plate 5, and works as the tap hour of converter 1, can adopt thinner steel plate 5.According to the present invention, thickness can be selected to be the steel plate 5 of 5mm ~ 8mm.
In the present invention, in order to prevent ladle 4 to be etched better, process for stamping such as can be adopted to manufacture steel plate 5 according to the interior shape of ladle 4, make steel plate 5 entirely be wrapped up in the inside of ladle 4 or partly wrap up in.
According to embodiments of the invention, steel plate 5 can be alloy-steel plate.When converter 1 starts to put steel, first molten steel 2 impacts alloy-steel plate 5, constantly impact in the process of alloy-steel plate 5 at molten steel 2, alloy-steel plate 5 is dissolved in molten steel gradually, its alloying component also enters in molten steel, thus reach the object of adjustment molten steel composition, reduce the inclusion content in molten steel, improve slab quality.
According to the present invention, the chemical composition of alloy-steel plate 5 can regulate according to the chemical composition of the chemical composition of steel billet to be manufactured and molten steel, to obtain satisfactory steel billet.
According to ladle erosion resistant method of the present invention, effectively can reduce mechanical erosion, reduce the reaction time of chemical erosion, reduce the inclusion content in molten steel, improve slab quality.In addition, according to ladle erosion resistant method of the present invention, the ladle that human factor causes can be greatly reduced and wear steel accident, thus reach the safe operation coefficient improving ladle, reduce the object that ladle lining fireproof material consumes.In addition, according to ladle erosion resistant method of the present invention, processing is simple, and cost is low, easy industrial realization.
Above implementations show example of the present invention, but scope of the present invention is not limited thereto, scope of the present invention is defined by the claims.
