Problems solved by technology

For the smelting of recycled materials, the method of bundling or welding the residual materials is adopted. The shape of the bundles is not uniform, and it is easy to be deflected during the feeding process. At the same time, the efficiency of bundling or welding is low.
The bottom contact area between the existing sponge titanium briquette electrode and the recycled material binding electrode is small in the horizontal pusher, which is prone to deflection and exceeds the range of electron beam smelting; Ingredient uniformity affects

preparation example Construction

[0026] A method for preparing a titanium and titanium alloy EB smelting bin, comprising the following preparation steps:

[0027] Step 1. Material selection: select pure titanium or titanium alloy plates with a thickness of 3~6mm or corresponding plate residues as plates for the material box, melt different materials, select plates or plate residues of corresponding materials, and select pure titanium plates below 1mm As the internal partition 5 of the material box;

[0028] Step 2, cutting; each material box is divided into 1 front end plate, 1 rear end plate, 1 bottom plate, 2 side plates, 1 tie bar and several partitions, and the plate is cut to be suitable for EB furnace feeding The specifications of the mouth size, in which the width and height dimensions are based on the size of the feed port, and a margin of 20~50mm and 50~150mm is reserved on the basis of the feed port size, and the length of the material box is greater than 1500mm;

[0029] Step 3. Tailor welding; Ta...

Embodiment 1

[0036] Melting TA2 material slab: select TA2 plate with a thickness of 3mm, and a part of 3~4mm plate residue as the plate for the material box, and select 0.5mm TA2 titanium plate as the inner partition of the material box.

[0037] Each material box has 1 front end plate, 1 rear end plate, 1 bottom plate, 2 side plates, 1 tie bar and 4 partitions. The size of the front and rear end plates is 450×450mm, and the bottom plate is 450×1600mm. The side plate is 450×1600mm, the lacing rib is 300×450mm, and the deviation is ±5mm. Splice the board remnants to the above specifications. 41 sets of box boards are cut.

Abstract

The invention provides a material box for titanium and titanium alloy EB smelting. The material box is used for containing smelting raw materials, the material box comprises a box body and a bottom plate, the box body comprises a front end plate, a rear end plate and two side plates arranged between the front end plate and the rear end plate, the front end plate, the rear end plate and the two side plates are sequentially connected end to end to form a quadrilateral box body, the bottom plate is installed at the bottom of the box body, a clamping groove is formed in the front end of the bottom plate, the clamping groove is communicated with the box body, a pressing plate is arranged at the rear end of the bottom plate in the length direction of the bottom plate in an extending manner, the pressing plate is arranged at the outer side of the rear end plate, and the clamping grooves and the pressing plates of every two adjacent material boxes are arranged in a matched manner. The material box is more suitable for EB horizontal pushing devices, compared with an existing raw material preparation manner, the efficiency is higher, the period is short, the cost is low, fed materials are straighter and more stable, the conditions of deflection and overturning are avoided, and therefore the stability and uniformity of titanium and titanium alloy EB smelting are improved.

Description

technical field [0001] The invention relates to the technical field of titanium material processing, in particular to a material box for smelting titanium and titanium alloy EB. Background technique [0002] Titanium and titanium alloys have the advantages of high specific strength, light weight, and corrosion resistance, and are widely used in aerospace, ships, weapons and equipment, and chemical industries. The traditional smelting method of titanium and titanium alloys is vacuum consumable arc melting (VAR). The raw materials are mixed and pressed to assemble welding electrodes. After 2~3 times of VAR melting, they are made into round ingots, and then rolled after forging and grinding. The billet required for the plate has a long manufacturing process and a large loss. Electron beam smelting (EB) can directly produce slabs, and obtain square billets after face milling. The process is short, the loss is small, and the cost is low. Large-scale slabs can be produced.
