Example Embodiment

[0019] Example 1

[0020] See figure 1 , An electrician round aluminum rod production process in front of the furnace, including the following steps:

[0021] Step 1: Add the raw materials and the regrind to the smelting furnace, control the temperature in the furnace, add molten aluminum and stir for 20-40 minutes to obtain molten aluminum;

[0022] Step 2: Use high-purity argon to spray the refining agent into the aluminum liquid for a refining treatment, after the refining, the slag is removed, and the sample is analyzed after standing;

[0023] Step 3: Add the calculated master alloy raw materials into the melting furnace, stir for 20-40 minutes, and control the temperature of the melting furnace to 750-800°C to obtain an alloy melt;

[0024] Step 4: Use high-purity argon gas to spray the refining agent into the alloy solution for secondary refining treatment, after the refining, the slag is left to stand;

[0025] Step 5: Use high-purity argon to spray the refining agent into the s...

Example Embodiment

[0027] Example 2

[0028] As a preferred embodiment of the present invention, in step one, the weight of the returned aluminum ingot is calculated based on the actual aluminum water temperature, the temperature of the returned aluminum ingot, and the temperature absorption of the returned aluminum ingot per ton of aluminum.

[0029] In this embodiment: by calculating the weight of the returned aluminum ingot, the increase of the master alloy raw material is determined, and the melting temperature is strictly ensured within the optimal processing temperature range.

Example Embodiment

[0030] Example 3

[0031] As a preferred embodiment of the present invention, both steps 1 and 3 adopt a combination of permanent magnetic stirring and manual stirring.

[0032] In this embodiment: by using a combination of permanent magnetic stirring and manual stirring, it is ensured that the molten aluminum in any part of the furnace in step one is fully stirred evenly, the uniformity of the intermediate alloy addition in step three is ensured, and the molten aluminum in the corners of the furnace is avoided If the mixing is not in place, the composition of the molten aluminum is uneven during the casting process.

Abstract

The invention discloses a stokehole production process of an electrician round aluminum rod, and relates to the field of electrician round aluminum rod production. The stokehole production process comprises the following steps that a raw material and a returned material are added into a smelting furnace; a refining agent is sprayed into molten aluminum by using high-purity argon to carry out primary refining treatment; an intermediate alloy raw material is added into the smelting furnace, and stirring is carried out for 20-40 minutes; the refining agent is sprayed into an alloy solution by using the high-purity argon for secondary refining treatment; and the refining agent is sprayed into the alloy solution subjected to standing by using the high-purity argon for tertiary refining treatment, and if the alloy solution reaches the production standard, the alloy solution flows into a launder and then stands for standby application. According to the stokehole production process of the electrician round aluminum rod, the permanent magnet stirring time is prolonged to be combined with manual stirring, the refining temperature is strictly controlled, the refining frequency is increased, so that the uniformity and stability of molten aluminum components are ensured; and the molten aluminum temperature in the whole launder is monitored in real time by additionally arranging a launder heating cover plate, so that the molten aluminum temperature stability is ensured, then the uniformity of the casting temperature is ensured, and components and tissues of a cast ingot are kept uniformas much as possible.

Description

technical field [0001] The invention relates to the field of production of electrical round aluminum rods, in particular to a pre-furnace production process of electrical round aluminum rods. Background technique [0002] Electrician round aluminum rod is the raw material for power cable companies to produce aluminum wire and cable for the power industry. The performance uniformity of the aluminum rod determines the product in the subsequent process, that is, the uniformity of the performance of the aluminum monofilament used in the wire, and ultimately determines the stability of the wire performance. performance and service life. [0003] In the production process of electrical round aluminum rods, because the shape of the furnace is square and the track of the permanent magnetic stirring is circular, it is easy to cause the molten aluminum at the corners of the furnace to be stirred improperly, and the composition of the molten aluminum is uneven during the casting proces...
