A method was developed for determining the thermal-shock resistance of steel casting plugs from the frequency of the mechanical oscillations using the sonic method without breaking the products. The sonic method of checking the properties of the plugs enables us to increase the working reliability of stopper devices during the casting of steel by means of a greater representation of the sample plugs, accelerating the certificating process by a factor of ten, and improving the working conditions. The method has been introduced for checking the properties of samples in enterprises of the refractories and metallurgical industry. The introduction of the method will give a substantial economic saving. [ABSTRACT FROM AUTHOR] |
