Weekly market calm tungsten, tungsten-based mainstream market stability maintenance operation. Tungsten concentrate prices stabilize, demand continues to slump, and with this weekend's upcoming November guide price this week, or wait for more miners, traded increasingly deadlocked. Wolframite guide price is expected in November fell to 95,000 yuan or / ton down.

It is understood that this morning tungsten ore prices compared with last weekend, no major fluctuations, market liquidity is more supply 55-60 grade, and the highest 60 scheelite spot market price is 90,000 yuan / ton, most inquiries are below 90,000 yuan / ton.

Waste tungsten market sentiment continued pessimism, holding cargo ship strong, low-cost resources on emerging markets, and the prices stabilized stabilized difficult. Month, market funding pressures eased, miners are mostly guided the sidelines introduced in November, is expected to near scrap tungsten market or temporarily stabilized stabilized.

Tungsten scrap prices continue to decline. Currently scrap tungsten drill mainstream transaction price excluding tax concentrated in the 165-172 yuan / kg, imported scrap tungsten blades and drawing dies 160-164 yuan / kg, domestic waste tungsten blade 150-153 yuan / kg, down 1-3 yuan. 70 degrees above the grinding tungsten scrap material 1.55-1.6 yuan / kWh, 50-70 degrees 1.49-1.55 yuan / kWh, 30-40 degrees 1.35-1.4 yuan / kWh, weak stability.

Overseas tungsten market continues to fall. 31 MB ferrotungsten evening Rotterdam offer 37.5-38.5 US dollars / kg of tungsten, the overall decline $ 1; paratungstate Europe offer $ 325-345 / ton level, transient stability; Hong Kong offer $ 338-360 / metric ton, down $ 2 lower. Expected short-term overseas tungsten City or continue weak adjustment.

Tungsten Carbide Milling Cutter Promotes Automobile Industry Development

Details: Category: Tungsten's News; Published on Friday, 31 October 2014 18:46; Written by xjq; Hits: 951

Tungsten carbide milling cutter’s development greatly improves the cutting ability of automobile industry, and at the same time, with the rapid development of manufacturing industry, some key industries like automobile have higher demands towards their cutting ability, which is in return greatly pushing tungsten carbide milling cutters to progress. The specially designed cutting tools as a set have made breakthrough on the tradition pattern of providing cutting tools only according to the present needs. It has successfully renewed the machining technology, improved the machining efficiency and lowered the machining cost.

Simulating processing in automobile industry becomes the driving force of the structure innovation of tungsten carbide milling cutters, which has contributed to the constant emerging of high-property cutting tools like multifunctional face milling cutters, module type vertical milling cutters and milling cutters with large feeding amount.

With the development and wide applications of high-efficiency numerically-controlled machine tools, the geometrical parameters of the commonly used cutting tools like tungsten carbide milling cutters, drill bits, etc., have been further diversified and changed the traditional monotonous pattern of standard tool parameters. Therefore, the cutters nowadays can adapt to different machining conditions and materials to be processed with an increasing cutting property. Some innovative tungsten carbide milling cutter structure can even produce new cutting effects, for example, compared to standard end mills, end mills with unequal helix angles can effectively reduce tool vibration, improve surface quality after machining, and increase the cutting depth and feed speed. The development of tungsten carbide thread milling cutters helps increase the thread machining efficiency to a high-speed cutting level.

Requirements of Digital Controlled Lathe on Tungsten Carbide Turning Tool

Details: Category: Tungsten's News; Published on Friday, 31 October 2014 18:56; Written by xjq; Hits: 1012

Tungsten carbide turning tool is widely used in digital controlled lathes, which can perform both rough and finish machining. To ensure relatively large cutting depth, high feeding speed in rough machining, the turning tools used in rough machining are required to have high intensity and good durability. Finish machining focuses more on machining precision, so it asks for higher precision and good durability.

Tungsten carbide turning tools used in digital controlled lathes have to be of good consistency in durability so as to facilitate the management towards tool life. In the management of tool life, the cutter with lowest durability is taken as a basis for durability assessment. In this case, the consistency in durability is more essential than there average service life.

In order to meet the requirements of digital controlled lathes automatic processing, improve product quality and production efficiency and carbide turning tool of modularization and standardization should be applied firstly.

The Dangerous X-ray for Radiation Study

Details: Category: Tungsten's News; Published on Friday, 31 October 2014 17:07; Written by TungstenAlloy; Hits: 975

X-rays have earned a bad reputation as playthings. No distinction can be drawn between the danger of exposure to a high-powered X-ray machine and the fallout of an H-bomb. It is a danger that extends not only to the experimenter but to his potential progeny. Human evolution is the result of mutations caused by, among other agents, cosmic rays and the radiations of radioactive elements in the earth's crust. Any radiation added by man alters the rate of mutation, and is rightly a cause of deep concern.

Export has solved the problem of equipment cost. Protection against exposure to the rays is not difficult to arrange. With these two considerations out of the way, X-rays open a range of experiments equaled by few other phenomena of physics. In addition to providing a source of X-rays for radiographs, a generator of X-rays in combination with accessories enables you to measure the charge of the electron, to study the structure of crystals, to observe the wave-particle duality of matter and radiation, and to probe other microcosmic corners. During this process, tungsten alloy material will be a suitable material for radiation protection.
