　目前，對(duì)日用瓷、衛(wèi)生瓷、電瓷、工藝瓷等的焙燒多采用隧道窯、梭式窯等***率熱工設(shè)備。其窯車(chē)支架絕大多數(shù)選擇SiC制品，尤其是橫梁采用R-SiC材質(zhì)，價(jià)格昂貴，大幅增加了使用成本。R-SiC方梁雖然高溫性能優(yōu)越，但仍然難以克服該材質(zhì)固有的抗氧化性差的致命弱點(diǎn)，表現(xiàn)為使用一個(gè)階段后，由于氧化造成的組織結(jié)構(gòu)脆弱，使其高溫強(qiáng)度 迅速衰減，縮短了使用壽命。
　　
　　我公司運(yùn)用先進(jìn)工業(yè)技術(shù)，采用進(jìn)口原料，適時(shí)推出了SF-F方梁，該方梁具有優(yōu)良的高溫性能和熱震穩(wěn)定性，承重大，直線度、平整度好，能在任何高溫氣氛下使用，不存在氧化還原現(xiàn)象，壽命可達(dá)300次以上。
　　
　　At present, the firing of table ware, sanitary ware, electronic ceramic and ceramic and craft ceramic mostly adopt the highly efficient thermal equipment such as tunnel kiln, shuttle kiln and so on. The supports of kiln car mostly are silicon-carbide products; especially crossbeams made of the very expensive R-SIC increase the expenses of consumption by a big margin. Although R-SIC square-beam has better high temperature properties, it is difficult for it to overcome its innate weakness of bad oxidation resistance, which can be proved form that its flexural strength at high temperature sharply reduces after used for a period of time, for the reason of that the structure becomes fragile due to oxidation. Undoubtedly, its using life is fairly short.
　　
　　Our company introduces the SF-F square-beam properly, it is produced with advanced technology and imported raw materials. SF-F square-beam has good properties at high temperature, thermal shock resistance, straightness and flatness and can bear heavier load of products, it also can be used in any atmosphere at high temperature without oxidation and reduction. The life will up to 300 times.
