rp graphite electrode
Advantages of rp graphite electrode manufacturer
1. The increasing complexity of mold geometry and the diversification of product applications have led to higher and higher requirements for the discharge accuracy of the spark machine.
The advantages of the rp graphite electrode are that it is easier to process, the removal rate of electrical discharge machining is high, and the graphite loss is small. Therefore, some group-based spark machine customers abandon the copper rp graphite electrode and switch to the rp graphite electrode. In addition, some special-shaped rp graphite electrodes cannot be made of copper, but graphite is easier to form, and the copper rp graphite electrode is heavier and not suitable for processing large rp graphite electrodes. These factors have caused some group-based spark machine customers to apply rp graphite electrode. 2. The rp graphite electrode is easy to process, and the processing speed is faster than that of the copper rp graphite electrode. For example, when using milling technology to process graphite, its processing speed is 2-3 times faster than other metals, without additional manual processing, while the copper rp graphite electrode requires manual grinding.
Similarly, if a high-speed graphite machining center is used to manufacture the rp graphite electrode, the speed will be faster, the efficiency will be higher, and there will be no dust problems. In these processes, choosing the right hardness tool and graphite can reduce tool wear and copper damage. If you compare the milling time of the rp graphite electrode with that of the copper rp graphite electrode, the milling time of graphite is 67% faster than that of the copper rp graphite electrode.
Generally speaking, the processing speed of the rp graphite electrode is 58% faster than that of the copper rp graphite electrode. In this way, the processing time is greatly shortened, and the manufacturing cost is reduced. rp graphite electrode broken 3. The design of rp graphite electrode is different from the traditional copper rp graphite electrode. In the rough machining and finishing of copper rp graphite electrode, many mold factories often have different reservations, and the reservations of rp graphite electrode are almost the same, which reduces the number of CAD/CAM and processing. This reason alone Enough to improve the accuracy of the mold cavity to a large extent. Of course, the first thing to figure out is how to use graphite materials and other related factors after the copper rp graphite electrode is transferred to the rp graphite electrode in the mold factory. Nowadays, some group EDM customers use rp graphite electrode for electrical discharge machining. Although the process of mold cavity polishing and chemical polishing is avoided, the expected surface finish can still be achieved. If you do not increase the time and polishing process, it is impossible to manufacture such a workpiece.
In addition, graphite can be divided into different grades. Only by using suitable graphite grades and EDM parameters in specific applications can the ideal machining results be achieved. If the operator uses the same parameters as the copper rp graphite electrode in the spark machine using the rp graphite electrode, the result will be disappointing.
If the rp graphite electrode material is strictly controlled, the rp graphite electrode can be set in a lossless state (loss less than 1%) during roughing, but the copper rp graphite electrode is not used. Graphite has the following high-quality characteristics that copper can’t match: Processing speed: high-speed milling is 3 times faster than copper, high-speed milling and finishing is 5 times faster than copper, it has good machinability, can achieve complex geometric shapes, light weight, and less than density 1/4 of copper, rp graphite electrode is easy to clamp. It can reduce the number of single rp graphite electrode, because it can be bundled into a combination of rp graphite electrode. The characteristics of general graphite carburizer with good thermal stability, no deformation and no processing burrs And application 1. The graphite recarburizer used in the product is made from natural burning carbonaceous minerals after careful screening, separation and high temperature recrystallization.
The fixed carbon content of the product is high, and the content of sulfur, phosphorus and nitrogen is far lower than that of coal carburizing agent. It has the advantages of good carburizing effect, high carbon yield, stable effect, and high liquid steel cleanliness. It is welcomed by the metallurgical industry and is the first choice for high-quality carburizing materials in the metallurgical industry.
2. Product features
(1) High absorption rate: the absorption effect of graphite carburizing agent with a carbon content of 80% is equivalent to that of coal carburizing agent with a carbon content of more than 90%.
(2) Easy to use: no need to adjust feeding equipment and methods.
(3) Energy saving and consumption reduction: high absorption rate and fast reaction speed, which can shorten the smelting time and achieve the effect of energy saving and consumption reduction.
The product is a non-metallic material with a melting point of about ℃, no residue during use, high utilization rate, convenient use, phosphorus and sulfur content far lower than pig iron, and stable performance. In terms of material properties, compared with the same amount of high scrap steel, the mechanical properties of a large proportion of pig iron used in the past have also been reduced by half a grade.
Therefore, compared with the traditional large-scale pig iron, the new process of carburizing and smelting has advantages in cost and product performance. Pig iron contains a lot of coarse hypereutectic graphite. This crude graphite is genetic. The melting temperature is low. Coarse graphite is not easy to eliminate. Crude graphite is inherited from the liquid state to the structure of solid cast iron. On the one hand, it reduces the achievable strength of cast iron and reduces the performance of the material. On the other hand, it reduces the expansion effect of graphitization that should occur during the solidification process. In cupola smelting, the amount of pig iron should be minimized, carburizing agent should be used to ensure high carbon equivalent, and the amount of scrap steel should be relatively increased. In this way, under high-temperature smelting conditions, carbon with good activity and a higher degree of graphitization can be obtained by carburizing.
The good shape of graphite is reflected in the casting, which is beneficial to improve the mechanical properties of the casting, reduce the tendency of shrinkage, and improve the processing performance.
