Today, rare earth market weakness steady, the market demand for light , few inquiries . Recently purchased less because some loose oxides and metal prices down in the short term is likely to continue downward.

Currently gadolinium products market , less turnover , inquiries are not active, Baotou manufacturers that now gadolinium oxide with ticket prices have been at 185,000 yuan / ton, gadolinium- iron with a ticket price of 195,000 yuan / ton, compared with 9 prices were already obvious downside , there are no signs of demand against warm , afternoon , or continue to shock .

Yttria market , prices were unchanged in recent days , traders quoted in the 7.5-7.8 yuan / ton or so , the price is slightly down slightly from last week . Recent yttrium oxide, samarium and other less attention , samarium oxide have less purchasing inquiries , insiders reflect recent orders basically no samarium oxide , have less purchasing, market price of about 22,000 yuan / ton.

Due to the recent light rare earth market , praseodymium neodymium , dysprosium or related products market weakness , the downstream magnetic scrap market was also affected, today part of the magnetic electric car scrap recyclers price continued to fall by 1 yuan / kg, according to a recycling factory disclosed, bad bad market quotations are not willing receiving strong magnetic late scrap prices may continue to fall.

Multiple composite rare earth tungsten electrodes swaging process string playing devices invented by two of the same model is used , the same frequency and speed of rotary forging machine (B201-B201, B202- B202) consisting of string playing devices multiple composite rare earth tungsten electrode material B202, B201 stage processing , B203, B202, B201 as tungsten and molybdenum in the regular machining processes , typically used for segmentation swaging process , is the use of B-203, B-202, B-201 swaging the swaging machine for processing . B-203, B-202, B-201 rotary forging machine for the device model , B-203 rotary forging machine rotary hammer stroke max , suitable for processing large workpieces ; B-202 rotary forging machine rotary hammer stroke , followed by appropriate machining small parts ; B-203 rotary forging machine rotary hammer stroke minimum , generally used for processing smaller parts. Die change system Φ6 other means swaging touched minimum diameter of 6mm.

Multiple composite rare earth tungsten electrodes swaging process parameters string playing devices formulation is based on multiple composite rare earth tungsten electrode materials developed organizational variation , the process of deformation of the electrode material organizational changes, recovery temperature and the recrystallization temperature is also based on the degree of deformation change so as to avoid multiple composite rare earth tungsten electrode material embrittlement recrystallization , also need to change the processing temperature to keep the temperature in the reply above the recrystallization temperature. Therefore, the equipment and technology to match the technical parameters , and is limited to multi-composite production and processing of rare earth tungsten electrodes , the main advantages of this process are: ( 1 )A process through two rotary forging dies , the original B202 6 step process reduced to three , the B201 process in four steps to reduce the current two , the processing efficiency doubled. ( 2 )Use of string playing techniques , billet machine after the first one rotary hammer forged quickly after entering the next rotary hammer forging machine , to avoid heat loss , and thus economic energy .

Last year, listed companies involved in purchasing and storage of rare earth authoritative sources , this earth is not yet officially started purchasing and storage company yet to receive notice of , " purchasing and storage generally only for state-owned enterprises , purchasing and storage price is basically a reference to the previous months the average price . "

The sources, purchasing and storage is scheduled Rare allow companies to bid , but only state-owned enterprises purchasing and storage , there are strict procedures and standards , " purchasing and storage are generally stable prices when purchasing and storage , the highest it will not purchasing and storage , the state may also be thrown out at the appropriate time . "

Earlier, experts said Chamber of Commerce , RE state purchasing and storage time and conditions are specific state secrets , the public will not be published . He further said that the earth will certainly be favorable purchasing and storage of raw materials involved in purchasing and storage enterprises, indirectly, would be favorable throughout the upstream rare earth industry .

For the rare-earth prices , the source said, purchasing and storage will support the prices of rare earth , while the earth as a strategic resource , the future price will be higher and higher, because the South will be less and less of heavy rare earths , and the current is limited to technology, marine rare earth the cost is too high .

According to public reports, in 2012 the price of purchasing and storage of rare earth allegedly by six months the average price of the acquisition . According to statistics, in 2013 the average price of rare earth 1-9 months : praseodymium neodymium 312,000 yuan / ton ; praseodymium 398,000 yuan / ton ; neodymia 313,000 yuan / ton ; europium oxide 4582000 / ton ; terbium oxide 3,667,000 yuan / ton ; dysprosium 1,938,000 yuan / ton ; erbium oxide 299,000 yuan / ton ; yttria 79,000 yuan / ton.

Recent widespread rumors of rare earth Shouchu yet today there has been progress .
