我厂钨酸分解槽铸石内衬,使用介质为盐酸,温度90～100℃,一般可使用2～3年。10立方米反应槽的铸石内衬,盐酸浓度为30～50克/立升,温度50～70℃,一般可使用十年。150吨盐酸贮槽的铸石内衬已使用了三年,情况良好。此外,铸石还用在防腐蚀地面及其他一些槽罐上,总面积达500平方米,使用铸石约60余吨,都取得很好效果。
I plant tungstic acid decomposition tank cast stone liner, the use of medium hydrochloric acid, temperature 90 ~ 100 °C, generally can be used for 2 to 3 years. The cast lining of the 10 cubic meter reaction tank has a hydrochloric acid concentration of 30-50 g/liter and a temperature of 50-70°C. Generally, it can be used for 10 years. The cast lining of the 150-ton hydrochloric acid storage tank has been in use for three years and is in good condition. In addition, the cast stone is also used on anti-corrosion floors and other tanks, the total area of 500 square meters, the use of cast stone about 60 tons, have achieved very good results.
