Description
Technical field
The utility model relates to plug, more particularly, relates to a kind of consumable electrode vacuum furnace welding plug.
Background technology
Titanium is a kind of new metallic material, divide pure titanium and titanium alloy, pure titanium contains the Ti amount more than 99%, measure about more than 85% and titanium alloy contains Ti, has light specific gravity (about 4.5g/cm3, iron and steel is 7.8g/cm3), corrosion-resistant, many advantages such as serviceability temperature is high (can reach at present more than 700 ℃), intensity is high, plasticity is good, be widely used in Aeronautics and Astronautics, ocean, building, automobile, the first-class military project vitals of golf, the high-grade product for civilian use.
Consumable electrode vacuum furnace is the advanced equipment that is used for smelting titanium or titanium alloy.According to the present condition of production both domestic and external, emphasis is partial to the product of large specification ingot shape.At present, according to the technological process of producing, before this press compacting---plasma welding machine welding---consumable electrode vacuum furnace is smelted.Press compacting: with existing press press device, the shape of compacting has Φ 440mm, Φ 540mm, Φ 740mm, Φ 840mm, wherein Φ 440mm and Φ 540mm are semi-circular shape (two semicircles are pieced together on the circular stainless steel plug of a Φ 85mm, be used for fixing the electrode block of compacting), Φ 740mm and Φ 840mm are 1/4 circle, the assembly unit principle is with noted earlier the same, every extruding electrode block height is about 150mm, become a complete electrode by being layering, and the top of electrode need to be equipped with a same steel grade, the fine and close circular slab of unidimensional and monoblock (centre bore Φ 85mm).Plasma welding machine welding: weld in the slit of suppress electrode block after needing after complete will suppress with the Plasma Welding stove, weld complete after with after the extraction of stainless steel plug, electrode can interosculate and not drop.Consumable electrode vacuum furnace is smelted: because the shape after the compacting of titanium extruding electrode is circular, centre bore after plug extracts runs through whole electrode, when producing, fine and close circular slab (be commonly called as and the be the titanium plate) centre bore that is positioned at the top must be crammed self-consuming furnace, because the material bar of burner connects auxiliary electrode, auxiliary electrode connects the electrode that needs to smelt and the pull-up of titanium electrode could be smelted, it is in the functions of the equipments scope that the material bar connects auxiliary electrode, and the electrode that the auxiliary electrode connection needs to smelt needs welding in the stove, therefore electrode head namely the titanium plate must be welded to connect with auxiliary electrode, centre bore must be crammed with the plug with steel grade, when guaranteeing to weld molten steel can not flow into electrode interior from the zone at top, thereby guarantee welding quality; Simultaneously, cramming of centre bore directly has influence on smelting quality, flows in the centre bore in case reason is molten steel, and be different according to the steel grade of smelting, and can affect the composition fluctuation, produces quality problems.
See also shown in Figure 1ly, at present, traditional material of cramming centre hole of electrode 1 is turning material 2 and titanium sponge 3, method is first with 2 bottoming of turning material, is positioned at the 100mm place of centre bore, crams the titanium sponge 3 of about 80mm again, 4 is that auxiliary electrode, 5 is the titanium plate among Fig. 1, and 6 are titanium sponge extruding electrode.The defective that such method exists is:
1, cram shakyly, because the density of cramming is inadequate, molten steel can flow into from the slit in the welding process, cause inside to melt simultaneously, the titanium sponge particle will be called in the bottom so that when welding molten steel flow into centre bore, can't guarantee to have enough molten steel amounts to weld, have influence on the quality of welding.
2, for reason given above, in case molten steel flows into, the composition of the whole Electrode for remelting that can affect is so that produce quality problems, for example rich titanium segregation.
3, practical operation in two steps so that the operation comparatively loaded down with trivial details.
The utility model content
For the above-mentioned shortcoming that exists in the prior art, the purpose of this utility model provides a kind of consumable electrode vacuum furnace welding plug, can avoid centre hole of electrode to be burnt when welding, prevents that molten steel from trickling to electrode interior.
For achieving the above object, the utility model adopts following technical scheme:
This consumable electrode vacuum furnace welding plug, be located in the titanium plate centre bore on titanium sponge extruding electrode top, described titanium plate centre bore is provided with interior step, described plug and titanium plate are with steel grade titanium material, and design is step-like accordingly, comprise continuous upper end cylindrical piece and lower end cylindrical piece, by being fixed in the titanium plate centre bore with interior step.
The interior step dimension of described titanium plate centre bore is: upper bore dia is 97mm, and height is 20mm; Lower bore dia is 80mm, and height is 32mm.
The diameter of the upper end cylindrical piece of described plug is 95mm, and height is 18mm, and the diameter of lower end cylindrical piece is 78mm, and height is 30mm.
The lower bore dia of the interior step of described titanium plate centre bore is identical with the centre bore of titanium sponge extruding electrode.
In technique scheme, consumable electrode vacuum furnace welding plug of the present utility model is located in the titanium plate centre bore on titanium sponge extruding electrode top, described titanium plate centre bore is provided with interior step, described plug and titanium plate are with steel grade titanium material, and design is step-like accordingly, comprise continuous upper end cylindrical piece and lower end cylindrical piece, by being fixed in the titanium plate centre bore with interior step.Adopt plug of the present utility model, when welding, can avoid centre hole of electrode to be burnt, prevent that molten steel from trickling to electrode interior, and make things convenient for fitting operation, improved operating efficiency, the phenomenon that has also prevented simultaneously the electrode dry joint occurs, and has improved welding quality and safety in production coefficient, has reduced production cost.
