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...
Nickel-based welding material for antioxidant, corrosion resistance, resistance to radiation ability, and the advantages of good comprehensive performance, are often used to service conditions demanding, high security requirements of welding structure. 690 nickel-based alloy is used in nuclear we...
What is vacuum high pressure gas quenching
Vacuum high pressure gas quenching refers to the hardenability materials of working die steels, high speed steels and alloy steels, which are heated to the critical temperature Ac3 or Ac1 after being loaded into the chamber of the vacuum furnace to achie...
The main purpose of metal smelting is to provide high quality metal melts for ingots.Therefore, it is necessary to study and determine the common rules in the smelting process of various pure metals and their alloys, so as to provide theoretical basis for formulating reasonable smelting process.
