As we all know , is a commonly used thorium tungsten electrode tungsten electrodes , tungsten electrodes cerium , lanthanum tungsten electrode , yttrium tungsten electrode
In addition to the tungsten electrode , there are other less common tungsten electrodes , such as those containing thorium 1% thoriated tungsten electrodes , thoriated tungsten electrodes 4% thorium , yttrium containing 2% yttrium tungsten electrode , and three kinds of alloying elements mixed tungsten electrodes called ternary rare earth tungsten electrodes , and not radioactive. Purpose is to balance the internal mobility of electrons and evaporation rates , making tungsten electrodes to maximize the performance , but also reduces the electron work function of electrons . Repeated arcing and arcing can easily and mixed oxides of the same type if the welding cycle is in the case of more than 15 minutes , its service life will be longer. Japanese technology research shows that ternary rare earth tungsten electrodes was very successful , and especially excellent welding performance . It is expected that more models for this product will appear in the U.S. market. Japanese and European markets have recognized this three yuan a combination of non-radioactive tungsten oxide electrode .
Packet transfer requirements: 10 / plastic box , the length is 150mm or 175mm, 1000 per carton.

A rare top-down regulation " storm" has begun. Recently, this reporter learned from the Ministry of authority , the Ministry is preparing a " special invoices " as a clue, involving the domestic rare earth mining, smelting and trading enterprise for large-scale separation of the special investigation, one by one register and check the conditions established under the earth management " black list " and categorized for management, to establish long-term regulatory mechanism .
With the previous inspection have other is that this rare remediation objects , including not only Baotou , Ganzhou , Guangdong and other places of rare earth minerals separation of rare earth mining and smelting enterprises, some of Shanghai , Beijing and other rare-earth trading companies are also the scope of the examination , a total of 1594 households.
" Once Rare illegal activities, in addition to local authorities for shutting down rectify such punishment, the rare earth companies will be registered into the earth ' blacklist ', including the people in charge ( the boss ) , will become the Ministry of Industry and local government focus monitoring objects , and local government accountability linked to prevent ' resurgence ' . " The source said.
As China's important strategic resource , in order to protect resources and the environment , China has adopted a more stringent policy of rare earth mining and production management . But the temptation of huge profits , free outside of the regulatory "black earth " industrial chain has continued to grow, not only the destruction of the environment and waste of resources , but also to the integration of rare earth great difficulty .
China Rare Earth Association Secretary-General Ma Rongzhang had anxiously said that at present the country illegally rare earth production capacity is close to the sum of legitimate businesses . In 2012 , for example, the South of heavy rare earth minerals total of 13,400 tons of mandatory plans . But according to Rare Earth Industry Association statistics, in the South mine in 2012 to produce at least 3.7 million tons, which can launch the South smelting enterprises ionic mineral separation , 70% of unknown origin .
More worrying is the situation from the past , often against production and sales of "black earth " special event is over, it began criminals rampant , some of the illegal exploitation of rare earth smelting separation plant are & ldquo ; limelight "after the resurgence . Individual local governments are also thinking of local protectionism , combat is not positive, but also in violation of national industrial policy, rare earth smelting and separation of rare earth projects in excess of authority , or even condone the illegal production and processing of rare earth behavior. "We want to solve the problem of repeated , worked out a more effective regulatory mechanism. "
Authorities said above , recently the Ministry has been used since last year, the list of enterprises Rare invoices , in accordance with enterprise registration underground distributed to local governments , and requires each local authority to all enterprises involved in rare earth raw materials procurement , production, processing and downstream customers fill out checklist case , the first phase of local self-examination requirement completed in October , followed by a second phase of eight ministries and commissions of the Joint Inspection , and finally to create a database of rare earth enterprises administered separately , for some tainted or repeated violations enterprises ( responsible person ) requires local governments to supervise the handling and implementation of the accountability system .
"The first is to block the source , through the protection and exploitation of mining and smelting separation enterprises supervision to prevent illegal exploitation or exceed the mandatory plan and oxides of rare earth ore mining products to the market ; followed by a thorough investigation of the flow through the earth sources of trade enterprises purchase and sales records registration investigation, if it is found trade enterprises selling products of unknown origin will be investigated and dealt with , to prevent trade enterprises have become the black earth ' bleached ' tool. " a rare Inspection Unit Ministry officials said.
August 26 to 30 , the reporter to follow the Ministry of Baotou Rare Earth inspection teams to conduct research informed that some selected scenes have unlawfully engaged in iron ore smelting and separation of rare earth , rare earth prices soaring once in the period earned " bowl full of pots overflow " in the local authorities under the crackdown has been forced to shut down now for several months. This reporter saw a number of domestic and farm located Wulateqianqi flotation involving rare earth enterprises are based on " recycled iron , sponge iron " in the name , cleverly evaded government regulators , plant and outside are dust and weeds , the scene of rare earth flotation device process is very simple, and basically there is no environmental protection equipment .
"In order to avoid regulation , these illegal concentrator will choose some of the sparsely populated, remote areas and mountains , it also gives us the work of great difficulty . Some plant Basically addition to local reports , there is virtually no way to discovery. "The local government authorities have pointed to a person in charge of abandoned open-air concentrator , said , " This place usually do not come into the car , on foot must take more than one hour , concealment is very strong , they are the first to use a forklift the road leveled and then transported rare earth ore . "
"Our next step will be to increase the intensity of rare earth remediation . In addition to meet the special rectification , but we have to put on the development of rare earth industry overall planning program to accelerate the development of Baotou Rare Earth industry consolidation extends to deep processing , and to strengthen and Bayan Obo mine tailings management and governance efforts. Moreover once the illegal mining, Pirates ore, smelting separation , etc. will be severely punished . " Baotou City Vice Mayor Xu Delin an interview with reporters said.
