FIELD: metallurgy.
SUBSTANCE: during the casting it is defined at least difference between molten metal consumption through the shutter and its design value and it is compared to its threshold valuation. Or it is defined difference between measured metal flow rate through the shutter and its design value and it is compared to its threshold valuation. Or it is defined one of the following parameters, inherent in fireproof plate: energy, spend per plates relative displacement, which is compared to its threshold valuation, or plates time in use in wear conditions, which is compared to its threshold valuation, or number of plates relative displacement, which is compared to its threshold valuation. According to results of comparison it is defined ability of recycling of mentioned plate.
EFFECT: objectivity increasing at decision-making relative to recycling of sliding shutter plate.
