Carbide forging is also known as forging die, with good heat resistance and anti-fatigue ability, which through the upper and lower mold clamping to exert a certain squeeze force, making die forging better mechanical and mechanical properties. There are many types of carbide forging die, mainly clas
Tungsten powder is made from tungsten oxide in the four-tube muffle furnace or multi-tube furnace with hydrogen reduction with particle size from 0.6-30 microns. Mainly has coarse, medium and fine granularity, silver gray powder, impurity content based on national standards.
Molybdenum wire is made from molybdenum rods with series of processing such as hot-rolling, forging, drawing and made into a variety of specifications. Molybdenum wire often breaks in the drawing production process , resulting in molybdenum wire into the material rate.
Coal-water slurry is a new coal-based liquid fuel that emerged from the 1970s, consisting mainly of 65% coal, 34% water and 1% chemical additives. Compared with other types of fuel, it has many advantages, such as low sulfur content, high combustion efficiency.
The recrystallization temperature of lanthanum-doped molybdenum wire is higher than pure molybdenum wire, and it is because small amount of La2O3 can improve the properties and structure of molybdenum wire. Besides, La2O3 second phase effect can also increase the room temperature strength of the mol
Under normal temperature, MoSi2 element is very brittleness, while under high temperature, it is plasticity, so the better way to install U Shape element is to hang it vertically from the furnace top through the support clamping chuck. The aim of such way is to avoid putting the mechanical stress directly to the element heat-generating end; otherwise the element will easily be broken.
