Single Chamber Industrial Sintering Furnace Temperature Control Mode 3 Zone

Description:

The high vacuum furnace is single-chamber, horizontal and periodic heating. It adopt low voltage and large current graphite heating element to heating, and it has multiple heating units, each unit controls the temperature separately. The whole process is automatically controlled, monitored, tracked and displayed and recorded by the computer.

It including control system, heating system, vacuum system, cooling water system, rapid cooling system, auxiliary system and safety system.

It adopt the structure of built-in graphite liner in insulation tube. In general, it meets the strict requirements of temperature uniformity and atmosphere uniformity in the sintering process of high-performance materials. The furnace structure design is advanced and reasonable, and it is easy to use and maintain.

Silicon carbide ceramics sintering process

Silicon carbide ceramic is a new and with good performance of the friction material.It has the quality of light weight,high heat intensity and strong resistance to radiation; and has property of high self-lubricating low friction coefficient, high hardness, wear resistance,good pair performance,high chemical stability, corrosion resistance,good thermal conductivity,high heat resistance Impact and so on.Since 1980s, the major domestic and foreign mechanical sealing companies use the silicon carbide as a new generation of high pv friction pairs of materials and mechanical sealing material.
According to the different manufacturing process, the performance of silicon carbide products are also different.Based on the manufacturing method , it is mainly named reaction sintering SiC, atmospheric sintering SiC, hot pressing sintering SiC and so on.

The reaction sintered SiC is composed of α-SiC powder, graphite powder, flux and binder.
After mixing them and forming,then it is placed in a crucible filled with silica fume. Put the crucible in the vacuum and heat it to 1600-1800 ℃.The silicon reacts with the carbon in the crucible to form β-SiC, forming a dense sintered body consisting of α-SiC, β-SiC and free silicon (10 to 20%). Due to the presence of free free silicon, the corrosion resistance of the reactive sintered SiC is reduced and got corrosion in the strong and strong oxidizing media.
The advantage of reaction sintered SiC is that the end product is with small shrinkage and good thermal shock resistance, which is suitable for mass production with low investment. For the end product , it has better effect that used in the mortar pump and slurry pump.
