Problems solved by technology

Usually, the sealing edges of aluminum melting furnaces are made of heterosexual refractory bricks. However, due to the above reasons, the sealing edges of refractory bricks are easy to wear and have a short life. Moreover, the maintenance period is long, which greatly delays the normal process production.

Abstract

The invention provides an improved round aluminum smelting furnace. The improved round aluminum smelting furnace comprises a round aluminum smelting furnace body, a furnace cover and a castable sealing edge fixed around a feeding port of the round aluminum smelting furnace body. The castable sealing edge is located between the round aluminum smelting furnace body and the furnace cover. By adoptingthe castable sealing edge, the improved round aluminum smelting furnace not only has relatively high mechanical strength and thermal shock resistance, but also is convenient to maintain and short inconstruction period, and reduces corresponding production loss. The masonry method of the castable sealing edge is simple and wide in applicability, and scaled popularization and application and industrial implementation are facilitated.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy preparation, in particular to an improved round aluminum melting furnace and a method for building a round aluminum melting furnace castable sealing edge. Background technique [0002] Aluminum alloy is a general term for alloys based on aluminum. The main alloying elements are copper, silicon, magnesium, zinc or manganese, and the secondary alloying elements are nickel, iron, titanium, chromium or lithium. According to the different metal elements contained in aluminum alloys, aluminum alloy plates can be roughly divided into 8 categories, 1 series is industrial pure aluminum, 2 series is aluminum copper alloy aluminum plate, 3 series is aluminum manganese alloy aluminum plate, 4 series is aluminum silicon Alloy aluminum plate, 5 series is aluminum magnesium alloy aluminum plate, 6 series is aluminum magnesium silicon alloy aluminum plate, 7 series is aluminum zinc alloy aluminum plate, 8 ...
