唐山市马家沟耐火材料厂是国内较有声望的耐火材料商品厂之一。玻璃行业用户占总用户的95％以上。近年针对建材工业用耐火材料的缺口,不断开发新产品。如玻璃窑用优质硅砖已研制成功,并已建成年产万吨的生产线,现已正式投产;浮法窑锡槽底砖已试生产,并已用在秦皇岛玻璃研究院,现又向太 Tangshan Majiagou Refractory Material Factory is one of the more prestigious refractories in China. The glass industry accounts for more than 95% of the total users. In recent years, new products have been continuously developed for the gaps in the refractory materials used in the building materials industry. For example, high-quality silicon bricks for glass kilns have been successfully developed, and a production line with an annual output of 10,000 tons has been completed. The production line has now been officially put into production. The float furnace kiln tin bottom brick has been trial-produced and has been used in the Qinhuangdao Glass Research Institute.
