Abstract

The invention discloses a furnace lid for a rare earth alloy smelting furnace, the smelting furnace and a method. The furnace lid for the rare earth alloy smelting furnace comprises a cover body and araw material rotary lifting device. The raw material rotary lifting device comprises a rotating rod, a rotating rod outer cylinder, a rotating motor, a fixed outer cylinder, a lifting motor, a connecting rod, a gear, a rack and a metal raw material clamping disc. According to the rare earth alloy smelting furnace, the yield of alloy products with large component melting point differences can be increased, and the production period can be shortened.

Description

technical field [0001] The invention relates to a furnace cover, a melting furnace and a method for a rare earth alloy melting furnace, in particular to a furnace cover, a rare earth alloy melting furnace and a method for a rare earth-zinc alloy rare earth alloy melting furnace. Background technique [0002] Galvanizing can effectively prevent steel corrosion and prolong service life. Therefore, galvanized steel sheets are widely used in construction, automobile, vehicle and ship industries. With the development of the national economy, especially the rapid development of the automobile industry, the demand for galvanized steel sheets is increasing year by year. However, due to the active chemical properties of zinc, the galvanized surface is easily corroded, and the products after corrosion seriously affect the appearance of the product. In order to improve the problem that the galvanized surface is easily corroded, rare earth metals can be added to the zinc. [0003] Rar...
