Aluminum rod continuous casting and rolling production line

Abstract

The invention relates to the field of aluminum rod production rolling, in particular to an aluminum rod continuous casting and rolling production line. The aluminum rod continuous casting and rollingproduction line comprises an aluminum furnace used for melting a raw material, a casting machine used for cooling and solidifying molten metal, a roll shearing pulling device used for pulling an aluminum rod formed by the casting machine, a continuous rolling machine used for rolling forming of the aluminum rod, and a taking-up device used for taking up. The taking-up device does not use rod leading oil, and heat dissipating oil fume pollution of the aluminum alloy rod is avoided while it is ensured that the surface of the aluminum alloy rod is not scratched; and additionally, a lubricating oil and emulsion circulating system is arranged in the continuous rolling machine, lubricating oil lubricates and cools a bearing and a gear independently, an emulsion cools a rolled piece independently, thus abrasion caused by a traditional emulsion to the bearing and the gear is effectively avoided, the service lives of the bearing and the gear of the continuous rolling machine are prolonged, andthe accidents of rod blocking and breaking caused by quick aging and abrasion of the bearing and the gear in the production process are avoided.

Description

technical field [0001] The invention relates to the field of aluminum rod production and rolling, in particular to an aluminum rod continuous casting and rolling production line. Background technique [0002] At present, the production process of aluminum rod continuous casting and rolling is generally raw material→melting furnace→holding furnace→launder→pouring pot→casting machine→hydraulic shear→active feeding device→continuous rolling mill→rod closing device. [0003] However, the traditional emulsion lubricated rolling mill is used in the continuous rolling process. During the rolling production process, the temperature of the rolled piece is relatively high, and water is required to cool the rolled piece during the rolling process. The bearings and gears of rolling mills operate under high-speed and high-temperature conditions, and lubricating coolants are also required to lubricate and cool the bearings and gears. However, at present, the existing continuous rolling mi...

Problems solved by technology

[0003] However, the traditional emulsion lubricated rolling mill is used in the continuous rolling process. During the rolling production process, the temperature of the rolled piece is relatively high, and water is required to cool the rolled piece during the rolling process.

The bearings and gears of rolling mills operate under high-speed and high-temperature conditions, and lubricating coolants are also required to lubricate and cool the bearings and gears. However, at present, the existing continuous rolling mills use emulsion to cool or During the rolling process, the emulsion is mixed with more impurities, mainly including solid particles, grease impurities, grease and emulsifiers, and insoluble impurities generated by calcium and magnesium ions in water, making the emulsion very Therefore, the use of emulsion to lubricate the bearings and gears of the continuous rolling mill will cause the bearings and gears to be damaged very quickly, and rod blocking and broken rod accidents often occur in the production process, forcing the production to be interrupted

Seriously affect the normal progress of production, reduce production, increase costs, and produce low efficiency
