Abstract
The proposed method for checking the state of the lining of a melting unit consists of measuring the electric parameters of equal portions of the lining, located along the perimeter of the melting unit. This is followed by determining the arithmetic mean and the maximum value of these parameters and comparing the two. The result of the comparison is indicative of the state of the lining. According to the invention, the device for checking the state of the lining comprises electrodes which are uniformly installed on the lining along the perimeter of the melting unit. The electrodes are connected to the inputs of an information unit, which provides information about the state of the lining, as well as to the inputs of a maximum value unit for determining the maximum value of a parameter being measured. One output of the maximum value unit is connected to the first input of a comparison unit for comparing the maximum value and the arithmetic mean of the parameter being measured. Another output of the maximum value unit is connected to the first additional input of the information unit and to the input of a mean determining unit for determining the arithmetic mean of the parameter being measured. The output of the mean determining unit is connected to the second additional input of the information unit, to the second input of the comparison unit, and to a power source. Placed in series with the output of the comparison unit are an amplification unit and a signalling unit. The proposed method for checking the state of the lining of a melting unit and the device for effecting this method make it possible to increase the accuracy of checking overall wear and local damage of the lining.
