Regular Power(RP) Grade Graphite Electrode

Regular Power(RP) Grade Graphite Electrode

 As we know, there are two ways to make iron. The blast furnace method and the electric arc furnace method. Graphite electrodes are widely used in electric arc furnace (EAF) and ladle furnace (LF) for steel production. It is the graphite electrodes inside the furnace that actually melt the iron. Graphite has high thermal conductivity and is very resistant to heat and impact. It also has low electrical resistance, which means it can conduct the large electrical currents needed to melt iron.

【数控生产线,一流的设备】

CNC production lines, first-class equipment

 

2008年,公司耗资2800万完成了对设备的数控改造。改造后的生产线可以将进料误差控制在10g以内。众所周知,石墨电极的生产技术简单工艺复杂。关键问题就是石墨电极各种原料的配比。自动化生产线严格控制原料的重量,做到比传统方法更为精确的配比。在这样的严格控制下,石墨电极成品比设计指标误差更小。目前主要指标的误差可以控制在0.2%之内。

In 2008, the company completed a cost of 28 million CNC transformation of the equipment. After the transformation of the production line can feed the error control in less than 10g. As is known, the production process of the graphite electrode is simple and complicated. The key issue is the graphite electrode the proportion of various raw materials. Automated production lines strictly control the weight of raw materials, so that the ratio of more accurate than traditional methods. In such strict control,Graphite electrode  finished product design error than the smaller. At present the main indicators of error can be controlled within 0.2%.

 

所以,只要客户能确定他的参数,我们就能生产出严格符合参数的产品。

Therefore, as long as the customer can determine his parameters, we can produce a strict compliance with the parameters of the product.

 

此外,我们公司具有一系列先进生产设备:100Ton 航吊,两架;数控微机中心,一台;雷蒙磨,两台;8吨混捏锅8台,煅后焦煅烧炉128罐,叉车铲车各3台等。

In addition, our company has a series of advanced production equipment: 100Ton Hang Hang, two; CNC computer center, a; Raymond Mill, two; 8 tons of 8 pots, calcined coke calcined 128 cans, Each 3 sets and so on.

 

【区域优势】

Regional advantages

 

巩义市荣鑫碳素位于河南省巩义市,相比国内其他几个较大石墨电极工厂,我工厂距离天津港、青岛港、连云港距离都比较近。这样在内陆运费方面也可以节省一些成本。

Gongyi Rongxin carbon is located in Gongyi City, Henan Province, compared to several other large domestic graphite elctrode factory, our factory from Tianjin Port, Qingdao Port, Lianyungang distance are closer. So that inland freight can also save some cost.
