The two-level process control has strict process requirements on the two-level control in the aluminum electrolysis production process, generally, the aluminum level of a 330KA series electrolytic cell is required to be 28-30 mm, the electrolyte level is required to be 17-19mm, the two-level process control is one of key factors for stable operation of the electrolytic cell, and the stable operation of the electrolytic cell is directly influenced. Therefore, the accuracy of the two-level measurement is crucial. Two-level measurement commonly used in the industry is a down measurement method which has the advantages of high efficiency and low accuracy. The lower measurement method is that the horizontal drill rod is directly extended into the bottom from a fire hole at the aluminum outlet end, the horizontal drill rod is extracted after standing for about 5 seconds, aluminum liquid and electrolyte liquid are cooled and solidified into solid on the horizontal drill rod, an obvious boundary is formed, and the distance between the boundary and the head of the horizontal drill rod is directly measured by a steel plate ruler to obtain the aluminum level. The method is convenient, fast and easy to operate. However, the bottom of the electrolytic cell corresponding to all the fire holes of the electrolytic cell is not perfectly flat, but has the phenomenon of unevenness. Therefore, the measured aluminum level is not the actual aluminum level, and a certain error exists. This will cause interference to the control and prejudgment of the electrolyzer index, resulting in significant deviation in the adjustment of the electrolyzer index and unstable operation of the electrolyzer.
At present, the state advocates high-quality development of various industries, fine management is more and more emphasized for aluminum smelting enterprises, the requirements on prejudgment and adjustment of indexes of an electrolytic cell are accurate, and the former rough management mode cannot meet the requirements of the current high-quality development. Therefore, how to solve the problem of aluminum level measurement deviation as soon as possible and reduce the measurement error as much as possible is one of the problems to be solved by each aluminum electrolysis aluminum enterprise.

Detailed Description
In the embodiment, referring to fig. 1 to 4, the aluminum horizontal up-measurement horizontal rack for aluminum electrolysis comprises a supporting mechanism, a level gauge 4 and a horizontal groove 3 for placing a horizontal brazing rod 7, wherein the horizontal groove 3 is installed on the supporting mechanism, and the level gauge 4 is installed in the supporting mechanism; a plurality of horizontal adjusting screws 5 used for adjusting the levelness of the whole horizontal frame are arranged on the supporting mechanism.
The supporting mechanism comprises a base 1 and a stand column 2, wherein the stand column 2 is installed on the base 1, a horizontal groove 3 is installed at the top end of the stand column 2, a level gauge 4 and a horizontal adjusting screw 5 are respectively arranged on the base 1, and the horizontal adjusting screw 5 penetrates through the bottom surface of the base 1 to form an adjustable supporting leg.
The base 1 is in an equilateral triangle structure, a horizontal adjusting screw 5 is respectively arranged at the position close to three corners of the base, and the level 4 is arranged at the central position of the base 1 through a fixed tray 6. The whole supporting mechanism is formed by welding, and the zero positions of the three horizontal adjusting screws 5 are corrected firstly when the level 4 is installed.
Each upright 2 is arranged along any height of the triangle formed by the base 1 so that the projection of the horizontal groove 3 coincides with the height of the base 1.
The horizontal groove 3 is a semicircular groove and is opened upwards, and the structure is beneficial to the placement and the adjustment of the horizontal brazing filler metal 7 to the horizontal state.
Each stand 2 adopts stainless steel square pipe to make, and horizontal groove 3, base 1, horizontal adjustment screw 5 and fixed tray 6 all adopt the stainless steel to make, prevent the influence of magnetic field magnetic force, and the surveyor's level is then for outsourcing.
As an application example, referring to fig. 5, the diameter of the horizontal groove 3 is 38.1mm, the cross section of the vertical column 2 is 38 × 38mm, the height of the vertical column is 142mm, the height of the base is 38mm, and the height supported by the horizontal adjusting screw 5 is 20 mm. When the aluminum electrolysis cell works, the horizontal brazing rods 7 are horizontally placed in the horizontal groove 3 and are vertically inserted into the electrolysis cell downwards, and the bottom ends of the horizontal brazing rods 7 need to penetrate through a boundary line between electrolyte liquid and aluminum liquid and be inserted into the aluminum liquid.
