However, this method can only use a high-strength metal temperature-measuring protective sleeve to avoid breakage when the pneumatic advances and retreats. The average service life of this protective sleeve is only 7 to 10 days. Therefore, it needs to be replaced frequently in practical applications. Heavy workload and high cost of use

Embodiment Construction
[0017] The present invention reforms the traditional orifice structure, moves the orifice bricks appropriately, forms a recessed hole at the discharge port in the furnace, and sets an obliquely inserted temperature measuring hole above the discharge port to measure the temperature of the molten aluminum. It is inserted in the concave hole obliquely. Since the molten aluminum in the discharge port flows during the discharge process, there will be no accumulation of aluminum slag, and the temperature measurement accuracy is naturally guaranteed.
[0018] The fixed aluminum industrial furnace mainly includes the furnace bottom 1, the furnace side wall 6 and the orifice brick 2, such as figure 1 In the temperature measurement structure shown, the orifice brick of the fixed aluminum industrial furnace is moved out, and a recessed hole is partially formed at the discharge port in the furnace, and an oblique measurement is provided above the orifice brick 2 and the beam of the castable ...

The invention provides an aluminum liquid continuous temperature measurement structure in a fixed aluminum industrial furnace. A flow-off brick of the furnace is outwards moved, a concave hole is locally formed on a flow pouring hole in the furnace, a casting material cross beam on the upper part of the flow-off brick is provided with an inclined temperature measurement hole, the contacting part between the inclined temperature measurement hole and a liquid level is provided with a big concave hole, the inclined temperature measurement hole has a horn-shaped structure from outside to inside, a horn-shaped hole has small exterior and big interior, a flame couple for measuring the temperature of aluminum liquid is obliquely inserted into the deep part of the aluminum liquid of a flow hole along the inclined temperature measurement hole, the flame couple is sleeved with a temperature measurement protective sleeve, the position of the head part of the flame couple utilizes the inner wall of the furnace as a boundary, and the root of the flame couple is fixed on the outer wall of the furnace outside the furnace. The technical proposal of the aluminum liquid continuous temperature measurement structure achieves the aim that aluminum liquid temperature is continuously and directly measured in the furnace, the phenomenon of blocking caused by aluminum slag can be effectively avoided, and the authenticity of the temperature measurement data is better. The structure has the advantages of convenient installation and long service life, and can be widely used in melting furnaces and maintaining furnaces in the aluminum process industry.
Description
Technical field [0001] The invention relates to measuring the temperature of molten aluminum, in particular to a structure for continuously measuring the temperature of molten aluminum in a fixed aluminum industrial furnace. Background technique [0002] In the melting and holding furnace of the aluminum processing industry, it is necessary to measure and control the temperature of the molten aluminum to reduce the oxidation and burning loss of the molten aluminum. In aluminum industrial furnace equipment, due to the strong corrosiveness of molten aluminum itself, coupled with frequent furnace loading, refining, slagging and other operations, the setting of temperature measuring thermocouples has always been a difficult problem to solve. [0003] There are two commonly used methods at present. The first temperature measurement program is to set a "concave" hole at a suitable position on the inner wall of the furnace, and the thermocouple for measuring the molten aluminum is inserte...
