Stokehole production process of electrician round aluminum rod

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...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that in the production process of electric 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 not be stirred properly, and the composition of the molten aluminum is not correct during the casting process. Uniform, and the change of casting temperature will affect the crystallization process to a certain extent, thus affecting the composition of ingots and aluminum rods, providing a pre-furnace production process for electrical round aluminum rods
