Problems solved by technology

[0008] However, these treatments should only be applied when the refractory lining is not in service
In other words, it enables regular inspection of the lining, but does not provide real-time monitoring of the integrity of the refractory lining

Embodiment Construction

[0027] The invention according to the appended claims provides a system for detecting any damage in a refractory lining for a molten metal vessel. The system is easy to install and use, and enables direct on-line monitoring of the integrity of the refractory lining during its operation with molten metal. The principle of the system consists in installing an open circuit in which the power supply has one pole connected to a conductive grid arranged beneath the surface of the refractory lining to be monitored, and to a The second pole of the metal contact electrode. If the monitored refractory lining is intact, the open circuit will not be activated. However, if there is damage to the refractory lining being monitored, this will allow molten metal to make conductive contact with the grid during operation, thereby closing the circuit and causing a current to flow in the circuit. If an alarm is connected in the circuit, the operator can be made aware of damage in the refractory ...

Abstract

The present invention relates to damage detection systems for refractory linings for molten metal vessels, comprising an electrically conductive grid disposed underneath the surface of the refractorylining closest to a molten metal when in use, one or more electrically conductive electrodes disposed in contact with the molten metal when in use and an electrical power source, wherein the electrically conductive metallic grid and the one or more electrically conductive electrodes are electrically connected to each other, such as to form an open electrical circuit powered by the said electricalpower source, and a detected closure of the said electrical circuit during normal use of the molten metal vessel indicates that the said refractory lining is damaged, or the presence of a molten metalduring normal operation of the vessel closes the said electrical circuit in case the refractory lining is damaged. The present invention relates to a method for detecting damage in a refractory lining during use, and the use of a damage detection system according to the invention.

Description

technical field [0001] The invention relates to a system for detecting damage in refractory linings, and a method of detecting damage in refractory linings, eg by using a system according to the invention. Background technique [0002] Refractories are materials that have properties that make them suitable for use as heat resistant barriers in high temperature applications. These materials are useful, for example, as linings for cupola furnace floors and siphons, in blast furnaces, runners, secondary and inclined runners, and more generally in vessels or vessel spouts, ladles, tundishes, In reaction chambers and tanks, said vessels or vessel spouts, ladles, tundishes, reaction chambers and tanks contain streams, channel streams or are suitable for facilitating industrial processing of liquid metals and slags or any other high temperature liquids, solids and gases. [0003] Unformed refractory materials have the ability to form seamless linings and are often referred to as m...
