最近,宁夏召集全区20多家碳化硅企业,推广一项国内外首创的碳化硅多芯炉冶炼技术,以提高企业科技含量,改变目前区内多数碳化硅企业亏损的现状。 近年来,我国碳化硅行业逐步向西部地区集中发展,其中,宁夏自80年代末开始发展碳化硅行业,目前年生产能力已经达到20万t,约占全国产量的17％。但由于初期建设的多是5000千伏安以下的小型单芯炉,热效率低、能耗高、产量低,并且炉芯热
Recently, Ningxia convened more than 20 silicon carbide enterprises in the region to promote a smelting technology of multi-core silicon carbide furnace pioneered both at home and abroad so as to improve the scientific and technological content of enterprises and to change the current situation of the majority of silicon carbide enterprises in the region. In recent years, China’s silicon carbide industry to gradually focus on the development of the western region, of which, Ningxia since the late 1980s to develop silicon carbide industry, the current annual production capacity has reached 200,000 t, accounting for 17% of national output. However, due to the initial construction of mostly 5000 KVA small single-core furnace, low thermal efficiency, high energy consumption, low output, and the furnace core heat
