Technological process
The preparation process of sintered tungsten rod is mainly as follows: static pressing of tungsten powder – pre sintering – vertical melting sintering
1. Molding process: powder molding is carried out by static pressure. The density of the briquette after molding...
Today, we are going to introduce silicon carbide ceramic, which is the best high temperature strength ceramic material, and its oxidation resistance is also the best of all non oxide ceramics, so it is widely used in various industrial fields. The following content is the three common sintering m...
Requirements for sintering method of bulletproof board silicon carbide ceramics:
The invention relates to a sintering method of silicon carbide ceramic for integral bulletproof insert plate, which is characterized in that the pre sintering steps are as follows: the blank body is installed on the ...
The difference between non – pressure sintered silicon carbide products and reaction sintered silicon carbide products
About high temperature sintered silicon carbide products, pressureless sintering and reaction sintering is the current domestic production of silicon carbide ceramics is th...
(1) Cleaning and drying
As in the oil quenching process, the ring mold is cleaned with emulsifying degreaser, and the ring mold is cleaned in the cleaning machine for 3-4h to remove oil, rust and iron chips in the mold holes.After taking out, put into the ring mold drying machine, drying temperat...
Vacuum oil quenching furnace and vacuum gas quenching furnace is relatively common, many customers always hesitate between the two, do not know which is better.The following for you to analyze the advantages and disadvantages of the two types of vacuum furnace, convenient for you to understand.

QPQ is an abbreviation of quench-polish-quench. Refers to the black metal parts into two different properties of the salt bath, through a variety of elements into the metal surface to form a composite infiltration layer, so as to achieve the purpose of parts surface modification. It did not under...
There are many ash and volatile substances in natural graphite, and the general graphite content is about 50%~90%. Therefore, when the graphite raw material is deeply processed into a graphite material, it is technically first purified. The quality of graphite purification determines the use char...
Oxygen exists as a trace impurity element in the superalloy in the form of solid solution and oxide inclusion. Figure 1 shows the Al2O3 inclusion in the nickel-based superalloy.The presence of oxygen in the solid solution state has basically no influence on the performance of the superalloy, whil...
