Abstract

The invention relates to the technical field of vacuum self-consuming furnaces, in particular to a vacuum self-consuming furnace crystallizer welded cylinder producing process and a welding assistive device, and solves the problems that currently a cylinder is formed by spinning or forging, the process is complicated, production cost is high and price is high. The crystallizer cylinder is formed in a welded manner by the aid of the welding assistive device, the technical prejudice that the cylinder can only be formed by spinning or forging in the prior art is overcome, indicators of the produced cylinder meet the requirements of the vacuum self-consuming furnace during smelting, on the basis of guaranteeing structural strength and accuracy of a crystallizer, producing difficulty is reduced effectively, production cost of the crystallizer is reduced, and market competitiveness of equipment is improved.

Description

technical field

[0001] The invention relates to the technical field of vacuum consumable furnaces, in particular to a process for preparing a vacuum consumable furnace crystallizer welded cylinder and welding aids. Background technique

[0002] At present, the vacuum consumable furnace (VAR) is mainly used for the production of titanium and titanium alloys. It is composed of stirring system, detection and automatic recording system.

[0003] The furnace is equipped with a crystallizer (copper crucible), which is put into a water-cooled jacket and connected to the positive pole of the melting power supply. The negative pole of the power supply is connected to the piston or "tie rod" (false electrode) which enters the furnace through a sliding vacuum seal. The steel to be smelted (consumable electrode) is clamped on the base of the control piston, and after the furnace is evacuated, the consumable electrode is lowered to trigger the arc with the slag at the bottom of the cry...
