Manufacturing Processes:
The manufacturing processes include: tungsten powder press forming→presintering→vertical sintering.
1.Moulding process: the density of the press block made by powder compacting is the 60~65% of theoretical density.
2.Presintering: under the temperature of 1200℃, the blank is put into hydrogen molybdenum wire furnace for 120min. After cooling to 250℃, move it away. After a presintering process can eliminate most of the adsorbed gas, thereby increasing the strength of th eproduct, which is conducive to the transport and the follow-up processes of sintered tungsten rod.
3.Vacuum sintering: sintering purpose is to increasing the purity and density, a sintering is a process of diffusing. Sintering temperature, atmosphere and holding time are the three main factors that affect the final product quality. If the product can be kept at 1650 ~ 1700℃, the metal impurities and gap elements would volatilize.
Advantages:
1.tungsten is the highest melting point of all metals.
2.High density.
3.Good mechanical properties.
4.High Modulus of elasticity.
5.High absorption capacity against x-rays and y-rays.
