Device for partially inserting into a melt in a melting furnace, comprises rod-shaped thermoelement units with a tip projecting into the melt, and a tubular-shaped holder receiving the thermoelement unit and fastenable at the furnace

摘要

The device (TEB) comprises rod-shaped thermoelement units (TE) with a tip (S) projecting into a melt (SM), and a tubular-shaped holder (H) receiving the thermoelement unit and fastenable at a melting furnace. The holder is provided for conducting a gaseous medium (G) to blow into the melt. A gap (SP), through which the medium is blowable into the melt, remains between an outer surface of the thermoelement unit and an inner surface of the holder. The holder has a first circular cross-section, and the thermoelement unit has a second cross-section, which is smaller than the first cross-section. The device (TEB) comprises rod-shaped thermoelement units (TE) with a tip (S) projecting into a melt (SM), and a tubular-shaped holder (H) receiving the thermoelement unit and fastenable at a melting furnace. The holder is provided for conducting a gaseous medium (G) to blow into the melt. A gap (SP), through which the gaseous medium is blowable into the melt, remains between an outer surface of the thermoelement unit and an inner surface of the holder. The holder has first circular cross-section, and the thermoelement unit has a second cross-section, which is smaller than the first cross-section at a predeterminable measurement. The thermoelement unit protrudes from the holder with its tip at a predefined measurement. The holder has a connector (AS) to introduce the gaseous medium for conducting into the holder, a fastener (F) to fasten the thermoelement unit to the holder, a sealing agent (D) to seal the connector opposite to the fastener, cooling lines or bores for conveying coolant, segmented openings for blowing the gaseous medium into the melt. The thermoelement units are arranged in a staggered manner, and protrude from the corresponding holder at various large measurements to project into the melt with different immersion depths. An independent claim is included for a melting furnace with a device for partially inserting into a melt.
