計算方法之一為k值法：作拉深件水平投影圖，在該投影圖面積方程中引入k值，利用面積相等原理解方程，求得k值，沿水平投影外沿加上k值，即為毛坯圖的外廓形狀。計算方法之二為拉深線法：沿拉深件水平投影圖外廓，在任意點作該點切線的法線，在該法線上以該點拉深件的高度為量，在法線上取截點。Ceramic grain filters ard made of refined pottery clays added with certain modifiers, and processed of grinding, mixing, shaping and high temperature sintering. they do not contain any substances that harmful to people or environment. they are hard and rough in surface, porous inside the structure, and have the advantages of high mechanical strength, large specific surface area and porosity. when used in water treatment, they behave a activated surface property, a great amount of pollutant entrapment, less water head loss in the filter bed, lower consumption of back - flush water, stable in chemical and gbiologic property, and long service life, ceramic grain filters is a new and efficient filter material to increase the water yield, upgrade the water quality, and save chemicals and energy
