Load Analysis of Rolls in a Rolling Mill: A Comparison of

T = 0.4 Vout × E Total load on the four posts P = T × Atotal E P = 0.4 Vout × E × Atotal This is the total load coming on the 4 posts of the rolling mill which is equal to the load coming on the rolls, as the load is just transmitted from the rolls to the housing through the chocks. Therefore the roll load is P = 0.4 Vout × E × AtotalОнлайн-запрос
