PRODUCT DETAIL PRESENTATION
The pressureless sintered silicon carbide sintering furnace is mainly used for ceramic non-metal firing. It is a high-purity, ultra-fine silicon carbide powder as a raw material, and a small amount of sintering aids such as boron, carbon, etc., in an inert gas or vacuum atmosphere at atmospheric pressure. In the case of sintering at a high temperature of 1950~2100 °C, the obtained product is almost completely dense and has a ceramic material with excellent mechanical properties.
VNPS PRESSURELESS SINTERING FURNACE
Product Features and Special Configuration
Application and characteristics of silicon carbide pressureless vacuum sintering furnace
It is widely used in the pressureless sintering process of silicon carbide (SiSIC) ceramics. The silicon carbide products produced by the pressureless sintering furnace have better wear resistance, high temperature resistance and corrosion resistance.
Efficient debinding/dusting device (with a new structure of air intake system).
Advanced, fast and maintenance-free rapid cooling structure. (avoiding the drawbacks of old-fashioned structures with low efficiency and easy water leakage)
A variety of temperature measurement methods (K, WRe and other thermocouples, infrared thermometers) or a combination of choices.
For the speciality of silicon carbide grinding cylinder, our company can customize vertical silicon carbide reaction sintering furnace; if necessary, telephone consultation; horizontal furnace, single-side / double-side reclaiming method; vertical furnace, upper/lower reclaiming
Optional configuration
Furnace: all-carbon steel / inner stainless steel / all stainless steel·
