Material temperature measuring device for soaking furnace

Abstract

The invention discloses a material temperature measuring device for a soaking furnace. The material temperature measuring device comprises a cylinder passing through a furnace wall, a guiding mechanism, and a driving mechanism. Four metal rods penetrate the cylinder; and two of the four metal rods are nickel-chromium alloy rods and the other two rods are nickel-silicon alloy rods. Guiding wheels are fixed on a rack and are in contact with the outer surface of the cylinder. The driving mechanism drives the cylinder to make axial reciprocating motion. A longitudinal insulating plate is arrangedinside the cylinder along the axial direction and separates the four metal rods mutually. A plurality of horizontal insulating plates are arranged inside the cylinder along the direction perpendicularto the axial direction and are distributed at intervals; and the horizontal insulating plates and the longitudinal insulating plate are fixed mutually. Lead screws are arranged at the tails of the metal rods. A limiting plate protruding radially is arranged at the shaft end of one side of the cylinder; and internal threads cooperating with the lead screws are formed in the limiting plates. Therefore, the temperature of the aluminum alloy ingot in the furnace can be measured accurately; the material temperature measuring device can be utilized repeatedly; and the temperature measuring is donequickly and efficiently.

Description

technical field [0001] The invention relates to the field of soaking furnace equipment, in particular to a material temperature measuring device for a soaking furnace. Background technique [0002] There are two types of temperature measurement for soaking furnaces in the aluminum processing industry. One is that each zone has a set of thermocouples for measuring the temperature of the furnace gas, which are usually placed in the furnace cavity, and the other is for measuring the temperature of the charge. Usually, a 5mm diameter thermocouple is pre-made when the charge does not enter the furnace. , A hole with a depth of 25mm, and a armored thermocouple with a diameter of 3mm is inserted into the ingot in advance, so that the temperature of the ingot during the soaking process can be measured, but this method is labor-intensive and time-consuming. It is also possible that the galvanic couple will fall off, resulting in failure of temperature measurement. Therefore, a new t...

One is that each zone has a set of thermocouples for measuring the temperature of the furnace gas, which are usually placed in the furnace cavity, and the other is for measuring the temperature of the charge. Usually, a 5mm diameter thermocouple is pre-made before the charge enters the furnace. , A hole with a depth of 25mm, and a armored thermocouple with a diameter of 3mm is inserted into the ingot in advance, so that the temperature of the ingot during the soaking process can be measured, but this method is labor-intensive and time-consuming. It is also possible that the galvanic couple will fall off, resulting in the failure of temperature measurement. Therefore, a new temperature measurement technology must be used to measure the temperature of the ingot to achieve the purpose of convenience, speed and reliability.
