The special of the Planetary ball mill grinding sample

Posted on: 四月 6th, 2016 by langfeng No Comments

planetary ball mill machine 1

In general, such as hard, metal powder and ore samples developed by different kinds of planetary ball mill, according to different materials, stainless steel ball mill, optional carbon steel ball mill pot can also be, great hardness material?

 

How about great hardness material? Dose planetary ball mill can be used?We should use tungsten carbide ball-milling jar. With a strong acid alkaline, corrosive samples, we should use common types of milling jar of PTFE, polypropylene, ultra high molecular milling tank may be suitable for food, medical, cosmetic industries requiring high purity sample mill applications.In exceptional circumstances, a planetary ball mill grinding of the sample, in order to avoid deterioration in the air or when the need polishing media can be used to vacuum gas canister vacuum ball milling or inert gas milling,vacuum ball milling tanks typically 304 stainless steel,When samples need to use the vacuum ball mill can grind but can’t use stainless steel material grinding, it can be milled in the stainless steel vacuum tank lining, such as nylon, PTFE, polyurethane, polypropylene, polyethylene, alumina, zirconia, and other materials, avoid contact while the sample with stainless steel milling can achieve vacuum and inert gas milling.

 

Based on the above principle basic can help you choose a suitable for your own use of ball mill can, of course, because the planet type ball mill industry widely, grinding samples were varied, if you still have a lot of demand for your own grinding doubts, please contact our planetary ball mill manufacturer, we can help you analyze doubt dispels doubts or provide you with free samples test.

The purpose of vanadium carbide?

Posted on: 四月 5th, 2016 by langfeng No Comments

VC powders

For cutting tools, manufacturing vanadium steel, manufacturing of high-performance steel and carbide cutting tools grain refiner, can significantly improve the properties of the alloy. Can also be used for thermal spray materials, plasma spraying, flame spraying, laser spraying, HVOF and so on. It can also be used for the production of wear-resistant thin film and semiconductor film.

Industrial Microwave Applications

Microwave Vacuum Sintering Furnace

Silicon nitride, silicon manganese alloy, manganese and iron nitride nitrogen solid solution. Now widely used in the preparation of oriented silicon steel, ultra-high-temperature gas turbines, aircraft engines, turbine blades and heat exchangers. Silicon nitride which has a high temperature thermal stability, Ke Ang thermal shock resistance, thermal shock resistance, chemical stability, good electrical insulation properties and so on. Manganese steel desulfurization plays in effect, can eliminate or reduce the heat caused by brittle due to sulfur, which can improve the performance of the thermal processing of steel; Meanwhile manganese can refine and improve the strength of pearlite grain pearlite steels, and improve the steel hardenability.

Conventional silicon manganese produced using vacuum resistance furnace, the process is the raw material after milling, briquetting, at 870 ~ 1370 ℃, prepared by a nitrogen atmosphere, nitrogen-containing product is about 26%. Shortcomings of the conventional method in that the material of the nitridation time long, and therefore high energy consumption.

Microwave push plate kiln or shuttle kiln temperature microwave and microwave nitriding process can be relatively short period of time in heating the material to heat up, shorten the production cycle, while saving energy; In addition, the experience can be obtained by microwave technology for nitriding reaction promoted, and therefore increased the nitrogen content of the product.

Microwave sintering technology make great breakthrough at refractory material

Posted on: 四月 5th, 2016 by langfeng No Comments

Refractory variety, according to the level of refractoriness is divided into ordinary refractories (1580 ~ 1770 ℃), high-grade refractory (1770 ~ 2000 ℃) and super refractories (2000 ℃ above); According to the chemical properties of refractory materials into acidic, neutral and alkaline refractory refractories. In addition, there are special occasions for refractories.

 

Acidic refractories silicon oxide (SiO2) as the main component, commonly used silica brick and clay. Silica brick is containing more than 93% SiO2 siliceous products, raw materials used are silica, silica brick scrap, etc. Acid resistant brick slag erosion ability, but are vulnerable to erosion of basic slag, its high load softening temperature, close to its refractoriness, the volume does not shrink after repeated firing, even slightly inflated.

 

Neutral refractory main products are: corundum bricks, high alumina bricks, silicon Mo brick, mullite brick, aluminum chrome brick, aluminum carbon brick, graphite or carbon bricks. Poor thermal shock resistance, low load softness. However, due to poor alkali erosion alumina brick, it can not be applied to the conditions of use of the key parts of the complex.

 

Langfeng Metallic refractory metal on the basis of acidic and neutral refractories disadvantage on the use of technology research and Insignificance sintering a frequency 0,3 300GHz, ie electromagnetic wavelength range within lmm lm.

 

Microwave sintering technology refers to the use of microwave heating method makes powder material up to a certain temperature in order to achieve sintering technology. Frequency microwave equipment for microwave sintering pyrometallurgical generally 2.45GHz, there is also 28GHz, 60GHz or higher frequencies.

 

Langfeng Metallic microwave sintering technology low cost, high efficiency, energy saving, environmental protection, energy saving, and so fully meet the requirements of high temperature refractory material sintering technology.
