A series of annealing furnace produced by our company, has a unique design,using the technology of Taiwan, its main features a square design, beautiful appearance, the shell is welded by steel plate and 5mm, using high-qualityaluminum silicate needled blanket lining, solid made by mould compression,paste in the furnace wall, double insulation composition, furnace, electric heating element adopts strap type resistance furnace with hanging on, with high aluminum refractory bolt tightening fixed, divided into three area on the middle and lower temperature. Bottom made of high strength lightweight refractory brick and high alumina brick castable made by combining. The furnace temperatureuniformity is good, the temperature difference is ± 5 ?, the furnace cover for the steel structure, the interior is lined with the same high quality refractory lining,blanket, furnace cover is provided with two sets of 2.2KW strong circulating fan,so that the furnace temperature uniformity. Furnace with a ring, cover is convenient in operation, the furnace using all fiber structure, which makes the furnace body small heat capacity, heat loss is small, the heating and cooling fast,good insulation properties, small heat loss, greatly improving the furnace thermal efficiency and production capacity, reduce electric energy consumption, long service life, convenient repair etc.. The furnace is suitable for special equipment:copper aluminum material industry.
