Embodiment 1

[0018] An aluminum-germanium alloy covering agent that can reduce the evaporation rate of lead bath alloys at 490 degrees. In terms of weight percentage, the chemical composition of the alloy is: Ba: 1.8wt.%, Mn: 0.6wt.%, V: 0.6wt.%, Sc: 0.5wt.%, Th: 0.3wt.%, Ge: 32.6wt .%, the balance is aluminum. The preparation method of the alloy: add the above-mentioned raw materials into the atmosphere-protected induction furnace, and use a silicon carbide crucible; induction heat to 700-800 degrees to form an alloy solution, and use the electromagnetic stirring effect to fully stir for about 10 minutes; put the alloy The liquid is kept at 700-800 degrees for 10 minutes and then poured into the equipment at the same level as the hot top for semi-continuous casting into the required round ingot. The ingot moves down at a speed of 6m / min. The material covers the surface of the lead bath alloy in the lead bath; wherein, the use temperature of the lead bath alloy is 480-550 degrees.

Abstract

The invention discloses an aluminum-germanium alloy covering agent capable of reducing the lead bath alloy evaporation rate and a machining technology of the aluminum-germanium alloy covering agent. The covering agent is prepared from, by weight, 1.8-2.0wt.% of Ba, 0.5-1.0wt.% of Mn, 0.5-0.8wt.% of V, 0.4-0.8wt.% of Sc, 0.2-0.5wt.% of Th, 30.0-38.0wt.% of Ge and the balance Al. The covering alloyis best in lead reducing effect and long in service life, steel wire lead quenching quality is not affected, worker operation is convenient, and the best lead reducing method is achieved for steel wire lead bath quenching production.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to an aluminum-germanium alloy. Background technique [0002] The heat treatment production of steel wire generally has two cooling methods: isothermal cooling and continuous cooling. For semi-finished steel wire for steel wire rope, isothermal cooling is generally selected. Austenite in steel wire is a stable phase above the critical temperature, once cooled below the critical temperature, it is in a thermodynamically unstable state, called supercooled austenite. The supercooled austenite undergoes transformation to form a new stable phase. During the production process of steel wires for steel wire ropes, cold-rolled wire rods must be drawn several times; in order to eliminate the work hardening of semi-finished steel wires and ensure good drawing performance of the steel wires, it is necessary to heat-treat the semi-finished steel wires. [0003] The steel used in the production...
