Xinhong carbon advantage: Strictly control of raw material ensures it is from the best origin; Advanced production technology & facilities &experienced workers; Strict quality tracing system to ensure each ge excels buyer needs; Technical assistance & after service are available whenever needed; Sufficient stock in factory to ensure competitive price&fast delivery; Graphite electrodes Graphite electrode is made of petroleum coke, needle coke, and bonding coal pitch. Its production process is: calcining, dosing, mixing, forming, baking and impregnation, graphitization in a high temperature of over 3000c, then precision machining. Graphite electrode is acting as a conductive body which release heat in the form of arc for heating and melting steel in the furnace.According to the application, it can be divided into regular power(rp), high power(hp) and ultra high power(uhp). Graphite electrode is an important conductive material in smelting industry with good electrical conductivity, thermal conductivity and high mechanical strength, good corrosion resistance under high temperature. Graphite electrode is widely used in eaf, lrf, submerged arc furnace(producing ferroalloy, pure silicon, yellow phosphorus, calcium carbide etc), resistance furnace (such as the graphitization furnace, glass melting furnace and silicon carbide furnace etc). Packed in wooden crate or as your requirment.

Luminous characters with tin, tin content of 50%, suitable for a variety of luminous characters welding, a 0.7kg, tin must be with the welding word po, dilute hydrochloric acid or tin solder solution used, more efficient! Temp heat welding word when used to preheat, preheat to the vent hole after the smoke to welding, welding tip position and welding position must be sticky dilute hydrochloric acid or tin solder solution, so welding will be solid , high-power heating core is to ensure that the high temperature to ensure a solid welding, copper head must be copper, and only copper can hang tin can be welded, when the middle of the welding when the pause, you can adjust the iron iron regulator, so the temperature will not fall, it will not dry, to ensure that the life of soldering iron! Stainless steel word production process: Stainless steel words are all stainless steel, this metal is mainly installed in the interior, and more high-end, but the requirements for the relatively high technology, especially the welding of this one. Here i would like to talk about the production of stainless steel word steps: Step 1: panel production, usually flat, there are three-dimensional, three-dimensional, spherical and so irregular panels, spherical and other highlights is to use the plate slowly knock, the other pattern is engraving machine engraved of. Step two: the edge of the very simple, with a slotting machine first slot, and then facing the panel to slot, or hand-held slot machine to slot, where welding where the slot, it is convenient, but for stainless steel edge of the knife when the wear and tear is relatively fast, nor too flexible, there are certain limitations, narrow places may not be able to slot. Step three: that is, welding this one is to see the welding master used a welding tool, and some with a soldering iron, and some use of argon arc welding, the funds allowed to use laser welding, are very good choice. Step four: the floor is installed on it.

We can supply copper wire rod and copper cathode, as copper extraction techniques refers to the methods for obtaining copper from its ores. The conversion of copper consists of a series of chemical, physical, and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated (concentrated). To do this, the ore is crushed. Then it must be roasted to convert sulfides to oxides, which are smelted to produce matte. Finally, it undergoes various refining processes, the final one being electrolysis. For economic and environmental reasons, many of the byproducts of extraction are reclaimed. Sulfur dioxide gas, for example, is captured and turned into sulfuric acid which is then used in the extraction process
