摘要
A plug for a probe nose is produced in one piece having two contiguous parts. The first part is a substantially cylindrical body designed to be inserted in the probe nose such that it ensures tightness between the probe and the plug body. The second part is a substantially conical or semi-spherical head, co-axial to the body and provided at the level of its junction with the latter with a shoulder by which it can abut on the end of the probe. The plug comprises an inner through conduit which connects the surface of the head with the free front face of the body. This conduit authorizes the discharge of a protective gas introduced into the probe, and it is possible by controlling the flow of this gas to assess the difference of pressure exerted on each side of the plug and to adjust accordingly the pressure of the protective gas in order to prevent both the ejection of the plug and the penetration into the probe of hot gases from the furnace. The invention finds an application in the probing of furnaces used for reducing materials containing pressurized gases, such as blast furnaces.
