As a lubrication of the spindle drive unit of the rolling stand It is proposed to switch to the oil-air lubrication system. The advantages of "oil-air" lubrication systems are indicated. The effect of iron-containing impurities on the performance of the lubrication system has been established. The methods of recognition theory for determining the boundary value of iron-containing additives in the working fluid of the lubrication system are analyzed. It has been established that for these purposes the “minimal risk” method is optimal, which, unlike the Bayesian method, is less labor-intensive. An example of the practical application of using the "minimal risk" method to determine the permissible content of iron chips in the working fluid of the "oil-air" lubrication system is given.
