Basic Introduction to Silicon Carbide Rauv Tube

Basic Introduction to Silicon Carbide Rauv Tube

Silicon carbide, feem ntau hu ua pob zeb diamond lossis carbon silicon pob zeb, yog ib qho kev sib xyaw nrog covalent bonds uas yuav luag tsis muaj nyob hauv qhov xwm txheej. Cov khoom siv no yog siv rau cov kav dej silicon carbide rauv. Xyoo 1890, Eword thiab G Acheson tau npaj silicon carbide thaum ntxiv silicon rau cov pa roj carbon monoxide los ua cov khoom siv pob zeb diamond. Nws muaj zog hardness, hnav tsis kam, oxidation kuj thiab lwm yam ntxwv, thiab yog dav siv nyob rau hauv aviation, machinery, automotive, metallurgy, tshuaj, electronics thiab lwm yam teb. Raws li cov txheej txheem sintering, silicon carbide tuaj yeem muab faib ua recrystallized silicon carbide ceramics, tshuaj tiv thaiv sintered silicon carbide ceramics, pressureless sintered silicon carbide ceramics, kub pressed sintered silicon carbide ceramics, high-temperature isostatic pressing sintered silicon carbide ceramics silicon carbide. Kev ua haujlwm ntawm silicon carbide npaj los ntawm ntau cov txheej txheem sib txawv heev, yog li cov txheej txheem sib txawv tuaj yeem siv los npaj thiab tsim cov silicon carbide ceramics nrog cov khoom sib txawv kom tau raws li ntau yam kev xav tau.

Corundum horseshoe zoo li lub rauv tube:

The corundum horseshoe shaped furnace tube is made of densely fused corundum as the skeleton, with a plastic matrix of inorganic or organic substances. After high-temperature sintering at>1730 degree, tubular, horseshoe zoo li tus, thiab ntau yam khoom tshwj xeeb zoo li corundum yog tsim. Siv rau hlau kos duab ntawm tungsten, molybdenum, tantalum, thiab cov hlau tsis tshua muaj, hmoov metallurgy sintering furnaces thiab hydrogen furnaces, thiab inflatable high-temperature electric furnaces. Qhov kub ua haujlwm ruaj khov tuaj yeem ncav cuag 1700 degree.

Silicon carbide furnaces muaj thermal conductivity zoo, siab thermal shock stability, siab load softening point, thiab zoo hnav tsis kam, thiab yog dav siv nyob rau hauv kev kho cua sov cua sov rauv. Feem ntau yog siv rau pwm, hlau quenching, annealing, lub thawv hom hluav taws xob rauv taws, thiab siv chav kuaj. Qhov kub hauv qhov cub tuaj yeem ncav cuag 1200 degree.
