Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited thereto.

[0023] The present invention provides a vacuum consumable furnace crystallizer welding cylinder manufacturing process, the main steps are as follows:

[0024] Simulate the production of a welding test plate with the same welding conditions as the cylinder body. The main considerations include material, welding temperature, heat treatment, heat preservation conditions, etc. The test plate is subjected to a tensile test under the second-level weld The reduction of the joint strength determines the thickness of the plate required for the cylinder; the plate is preferably T2 or TP2 copper plate, which can meet the specific needs of special steel smelting in vacuum consumable furnaces;

[0025] The selected boards are blanked at one time, and the trimming process is carried out on the blanked cylinder boards, that is, planin...

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...
