Description
本發明有關一種應用在電弧開槽加工方法的炭棒，尤指一種結合鋁或鋁合金為主要導電材料來取代電鍍銅的開槽炭精棒。The invention relates to a carbon rod applied in an arc slotting processing method, in particular to a slotted carbon rod which is combined with aluminum or aluminum alloy as a main conductive material instead of electroplating copper.
目前市面上現有電弧開槽加工的炭棒，主要都是使用電鍍銅作為開槽炭精棒的主要導電材料，請參閱第1圖所示，傳統的開槽炭精棒(Gouging Carbon)為炭棒10表面透過配合銅板11電鍍後，披覆形成一銅鍍層12，降低電極棒電阻藉以傳導產生電弧所需要的高電流，但銅於高溫燃燒時產生的煙霧將對人體有害。At present, the existing arc-grooving carbon rods on the market mainly use electroplated copper as the main conductive material of the slotted carbon rod. Please refer to Figure 1, the traditional slotted carbon rod (Gouging Carbon) is carbon. After the surface of the rod 10 is plated through the copper plate 11, it is coated to form a copper plating layer 12, which reduces the high current required for the arc to conduct the arc, but the smoke generated when the copper is burned at a high temperature is harmful to the human body.
另外，現有的電鍍銅製程產生大量的含銅離子廢水以及電鍍產生酸性氣體，容易造成水質、土壤及空氣的重金屬汙染，因此必須設置對應的環保設備，然而，在環保意識日益提升的當下，將造成製造成本的逐漸高漲。In addition, the existing electroplating copper process produces a large amount of copper ion-containing wastewater and electroplating to generate acid gas, which is likely to cause heavy metal pollution of water, soil and air. Therefore, it is necessary to set corresponding environmental protection equipment. However, in the current environmental awareness, This has led to a gradual increase in manufacturing costs.
由於傳統電鍍銅方式具有危害人體之缺失，且鋁材無法以電鍍的方式與炭棒結合，故現有的熔射工法利用高溫將鋁熔化噴塗於碳棒表面後，再施以接近熔點溫度重熔再處理，消耗的能量非常大，使用上非常不便。Since the traditional electroplating copper method has the disadvantage of harming the human body, and the aluminum material cannot be combined with the carbon rod by electroplating, the existing spraying method uses high temperature to melt and spray aluminum on the surface of the carbon rod, and then remelting near the melting point temperature. After reprocessing, the energy consumed is very large and it is very inconvenient to use.
因此，目前開發出一種鋁製開槽炭精棒(Gouging Carbon)，其主是利用熔射的方式將鋁材披覆於炭棒表面，再以金屬熔點以下燒結。但傳統熔射工法的鋁材能覆著在炭棒的表面量少，往往造成材料浪費，且鋁材容易氧化披覆的金屬間密著性較差電阻偏高，造成電極棒消耗快速使用壽命低下，且加上必須再次燒結造成能源耗損經濟性差。Therefore, an aluminum grooved carbon rod (Gouging Carbon) has been developed, which is mainly used to spray aluminum on the surface of a carbon rod and then sintered below the melting point of the metal. However, the aluminum material of the traditional spray method can cover the surface of the carbon rod with less amount, which often causes material waste, and the aluminum material is easily oxidized, and the adhesion between the metal is poor, and the resistance is high, resulting in rapid consumption of the electrode rod and low service life. And the need to re-sintering causes energy consumption to be poor.
然而，由於以鋁材作為導電材料面臨到如前述之困難，故有人研發出使用押出成型的方法，在導電性金屬的外圍披覆以人造石墨為主要材料及結合劑(煤焦油、瀝青)混練成型後、以金屬熔點以下的溫度不活性環境下燒結。但由於現有炭棒電極燒結須達1000℃以上高溫，已超出鋁及大部份金屬的熔點，若以低溫燒結成的炭棒電阻值偏高，充填惰性氣體的不活性環境燒結條件成本高且無法連續式生產。However, since aluminum is used as a conductive material to face the aforementioned difficulties, a method of using extrusion molding has been developed, in which the periphery of the conductive metal is coated with artificial graphite as a main material and a bonding agent (coal tar, pitch) is kneaded. After molding, it is sintered in an inactive environment at a temperature below the melting point of the metal. However, since the sintering of the existing carbon rod electrode has to reach a high temperature of 1000 ° C or higher, the melting point of aluminum and most metals has been exceeded. If the resistance of the carbon rod sintered at a low temperature is high, the inert gas filling condition of the inert gas is high and the sintering condition is high. Continuous production is not possible.
此外，亦有人研發出使用金屬棒插入炭棒內後以金屬熔點以下溫度燒結，但是由於方法因未達金屬熔點，故金屬與炭棒之間有著密着性不足之問題。有鑑於目前現有炭精棒仍有前述諸多缺失，故傳統炭精棒的製成及結構實有改良創新的必要。In addition, it has also been developed to use a metal rod inserted into a carbon rod to sinter at a temperature below the melting point of the metal. However, since the method does not reach the melting point of the metal, there is a problem of insufficient adhesion between the metal and the carbon rod. In view of the fact that the existing carbon rods still have many of the aforementioned defects, the manufacture and structure of the conventional carbon rods are necessary for improvement and innovation.
本發明之主要目的在於提供一種利用鋁或鋁合金取代電鍍銅成為主要導電材料的開槽炭精棒，並以熔融狀態壓注入炭棒內部，降低了傳統鋁熔射與炭棒結合所需的能量消耗，並改善熔射時金屬噴出的附着量少且塗層厚度均勻性不易控制的問題。The main object of the present invention is to provide a slotted carbon rod which is made of aluminum or aluminum alloy instead of electroplated copper as a main conductive material, and is injected into the inside of the carbon rod in a molten state, thereby reducing the need for the combination of the conventional aluminum spray and the carbon rod. The energy consumption is improved, and the problem that the amount of adhesion of the metal sprayed during the spraying is small and the uniformity of the coating thickness is not easily controlled is improved.
