Description
本發明係有關一種盛鋼桶，更特別有關一種具有橢圓弧形底板之盛鋼桶。The present invention relates to a steel ladle, and more particularly to a steel ladle having an elliptical curved bottom plate.
在鋼鐵廠、金屬冶鐵廠中，會使用到盛裝熔銑和熔鋼或金屬的桶子。一般來說，由於製造上較為簡單，傳統盛鋼桶的底板均為圓形設計。然而，圓形結構的盛鋼桶具有使用壽命較短，亦即可供盛鋼、盛銑、澆鑄等冶煉製程之次數較少，以及容積率較低等之缺點，不利於降低煉鐵、煉鋼等冶煉製程之成本。In steel mills and metal smelting mills, barrels for melting and melting steel or metal are used. Generally speaking, due to the relatively simple manufacturing, the bottom plate of the traditional ladle is circular. However, the circular steel drum has a short service life, that is, the number of times of smelting processes such as steel, milling, casting, etc., and the low volume ratio, which is disadvantageous for reducing ironmaking and refining. The cost of steel and other smelting processes.
有鑑於此，便有需要提出一種方案，以解決上述問題。In view of this, there is a need to propose a solution to solve the above problems.
本發明提供一種盛鋼桶，具有較大的盛鋼容積。The present invention provides a steel ladle having a larger volume of steel.
為達上述目的，本發明之盛鋼桶，包含：一橢圓弧形的底板；一桶身，由該底板的周緣向上延伸出，該桶身具有一橢圓形的開口；以及兩吊耳，設置在該桶身的外側，其中該兩吊耳的軸線係垂直於該橢圓開口的長軸。In order to achieve the above object, the steel drum of the present invention comprises: an elliptical curved bottom plate; a barrel body extending upward from a periphery of the bottom plate, the barrel body having an elliptical opening; and two lifting ears, On the outside of the barrel, the axes of the two ears are perpendicular to the long axis of the elliptical opening.
根據本發明之盛鋼桶，其中該橢圓開口的中心在該橢圓弧形的底板上的投影係與該橢圓弧形的底板的中心重合。According to the ladle of the present invention, the projection of the center of the elliptical opening on the elliptical curved bottom plate coincides with the center of the elliptical curved bottom plate.
本發明另提供一種製造上述盛鋼桶的方法。The present invention further provides a method of manufacturing the above-described steel ladle.
於一實施例中，本發明之盛鋼桶之製造方法包含：提供複數個圓形的底板；將各該圓形底板裁切部分下來；將裁切下來的該等部分底板組合焊接，以形成一近似橢圓弧形的底板：以及將一桶身與該近似橢圓弧形的底板焊接。In one embodiment, the method for manufacturing a steel ladle according to the present invention comprises: providing a plurality of circular bottom plates; cutting each of the circular bottom plates; and welding the cut portions of the bottom plates together to form An approximately elliptical curved bottom plate: and a barrel body welded to the approximately elliptical curved bottom plate.
根據本發明之盛鋼桶之製造方法，其中該近似橢圓弧形的底板係由兩塊大小及形狀相同的第一部分底板以及兩塊大小及形狀相同的第兩部分底板所組合焊接而成，該第一部分底板的大小係不同於該第二部分底板的大小。According to the manufacturing method of the ladle according to the present invention, the bottom plate of the approximately elliptical arc is formed by welding two first bottom plates of the same size and shape and two second partial bottom plates of the same size and shape. The size of the first portion of the bottom plate is different from the size of the bottom portion of the second portion.

根據本發明之盛鋼桶之製造方法，其中該桶身外側設置有兩吊耳，該兩吊耳的軸線係垂直於該橢圓開口的長軸。According to the manufacturing method of the ladle according to the present invention, the outer side of the barrel is provided with two lifting ears, and the axes of the two lifting ears are perpendicular to the long axis of the elliptical opening.
根據本發明之盛鋼桶之製造方法，其中該橢圓開口的中心在該橢圓弧形的底板上的投影係與該橢圓弧形的底板的中心重合。According to the manufacturing method of the ladle according to the present invention, the projection of the center of the elliptical opening on the elliptical curved bottom plate coincides with the center of the elliptical curved bottom plate.
為了讓本發明之上述和其他目的、特徵和優點能更明顯，下文將配合所附圖示，詳細說明如下。此外，於本發明之說明中，相同之構件係以相同之符號表示，於此先述明。The above and other objects, features, and advantages of the present invention will become more apparent from the accompanying drawings. In the description of the present invention, the same components are denoted by the same reference numerals and will be described.
參考第1、2圖，本發明之盛鋼桶100具有橢圓弧形的底板110，該橢圓弧形的底板110具有一長軸112及一短軸114。由底板110的周緣向上延伸出有一環狀的桶身120，該桶身120具有橢圓形的開口，其中該橢圓形的中心在底板110上的投影係與橢圓弧形底板110的中心重合。另外，在桶身120的外側設置有一對吊耳122，可讓掛鉤鉤住以將整個盛鋼桶100吊起，其中兩吊耳122的軸線124係垂直於桶身120的橢圓開口的長軸。Referring to Figures 1 and 2, the ladle 100 of the present invention has an elliptical arc-shaped bottom plate 110 having a major axis 112 and a minor axis 114. Extending upwardly from the periphery of the bottom plate 110 is an annular body 120 having an elliptical opening, wherein the projection of the center of the ellipse on the bottom plate 110 coincides with the center of the elliptical curved bottom plate 110. In addition, a pair of lifting ears 122 are disposed on the outer side of the barrel 120 to allow the hooks to be hooked to lift the entire ladle 100, wherein the axes 124 of the two lifting ears 122 are perpendicular to the long axis of the elliptical opening of the barrel 120. .
根據本發明之盛鋼桶100，其中橢圓弧形的底板110係可以機械熱間或冷間旋壓加工成形，分塊組合焊接構成。詳細而言，由於一體形成的橢圓弧形底板110非常不易製作，因此係先以機械熱間或冷間旋壓加工的方式形成複數個大小不同的圓形底板。而後將各圓形底板裁切部分下來，再將裁切下來的部分圓形底板組合焊接，以形成近似橢圓弧形的底板110。舉例來說，參考第5、6圖，我們可以製作兩塊大小不同的一第一圓形底板310與一第二圓形底板410，並在第一圓形底板310上裁切下兩塊大小及形狀相同的部分底板312，以及在第二圓形底板410上裁切下兩塊大小及形狀相同的部分底板412。接著將裁切下來的四塊部分底板312、412組合焊接，即可得到如第3、4圖所示近似橢圓弧形的底板110。同樣地，我們也可以將八塊部分的圓形底板焊接起來，來得到本發明的底板110。以上述組合焊接的方式形成底板110後，再將桶身120與底板110焊接，即可得到本發明之盛鋼桶100。According to the ladle 100 of the present invention, the elliptical arc-shaped bottom plate 110 can be formed by mechanical hot or cold spinning, and combined by block welding. In detail, since the integrally formed elliptical curved bottom plate 110 is very difficult to fabricate, a plurality of circular bottom plates of different sizes are first formed by mechanical hot or cold spinning. Then, the circular bottom plates are cut down, and the cut partial circular bottom plates are combined and welded to form a bottom plate 110 having an approximately elliptical arc shape. For example, referring to Figures 5 and 6, we can make two first circular bottom plates 310 and a second circular bottom plate 410 of different sizes, and cut two sizes on the first circular bottom plate 310. And a partial bottom plate 312 having the same shape, and two partial bottom plates 412 having the same size and shape are cut on the second circular bottom plate 410. Then, the cut four partial bottom plates 312, 412 are combined and welded to obtain a bottom plate 110 having an approximately elliptical arc shape as shown in Figs. Similarly, we can also weld an eight-part circular base plate to obtain the base plate 110 of the present invention. After the bottom plate 110 is formed by the above-described combination welding, the barrel 120 is welded to the bottom plate 110 to obtain the ladle 100 of the present invention.
根據本發明之具有橢圓弧形底板之盛鋼桶，可在不改變現行吊運天車之吊鉤間距的情況下，亦即不改變現行傳統圓形盛銑、盛鋼之吊運機具與設備的情況下，增大盛鋼桶的容積，藉此增加熔銑、熔鋼之盛裝容量。此外，本發明之盛鋼桶因具有橢圓形的造型，能夠在傾鋼側、卸鋼側以砌磚或澆鑄耐火襯方式增加厚度，延長盛鋼桶的使用壽命。According to the present invention, the steel drum having the elliptical curved bottom plate can be used without changing the spacing of the hooks of the current lifting crane, that is, without changing the current conventional circular milling, steel lifting equipment and equipment. In this case, increase the volume of the ladle, thereby increasing the capacity of the melt-milling and the molten steel. In addition, the steel drum of the present invention has an elliptical shape, and can increase the thickness on the inclined steel side and the unloading side by bricklaying or casting refractory lining to extend the service life of the steel drum.
根據本發明之盛鋼桶，同樣適合現行傳統圓形桶之桶內砌築式耐火磚襯、或桶內設模澆鑄式之耐火襯。The ladle according to the present invention is also suitable for the refractory brick lining in the barrel of the current conventional round barrel or the refractory lining in the barrel.
根據本發明之盛鋼桶，與傳統式圓形盛鋼桶一樣，易於鑄模、連鑄機等的使用、點檢與維修，而不會增加額外的工作負擔。The ladle according to the present invention, like the conventional round ladle, is easy to use, inspect and repair the mold, the continuous casting machine, etc. without adding an additional work load.
雖然本發明已以前述實例揭示，然其並非用以限定本發明，任何本發明所屬技術領域中具有通常知識者，在不脫離本發明之精神和範圍內，當可作各種之更動與修改。因此本發明之保護範圍當視後附之申請專利範圍所界定者為準。While the present invention has been disclosed by the foregoing examples, it is not intended to be construed as limiting the scope of the invention, and the invention may be modified and modified without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
