Abstract

The low-cost pouring system comprises a straight pouring gate (1) and six transverse pouring gates (2) which are of an integrated structure, the straight pouring gate (1) is cylindrical, the six transverse pouring gates (2) are located at the bottom of the straight pouring gate (1), one ends of the six transverse pouring gates (2) are connected with the straight pouring gate (1), the six transverse pouring gates (2) are located on the same horizontal plane and are evenly distributed in a radial shape, and the other ends of the six transverse pouring gates (2) are connected with the straight pouring gate (1). The other ends of the six cross gates (2) are of a bifurcated structure and are respectively provided with a top pouring gate (3) and a bottom pouring gate (4), the top pouring gate (3) corresponds to a molding top pouring impeller (6), and the top pouring gate (3) corresponds to a molding bottom pouring impeller (5). Production benefits are greatly improved, and the problem that an existing impeller pouring system for casting titanium alloy is low in metal utilization rate is solved.

Description

technical field [0001] The invention relates to a low-cost gating system for titanium alloy impeller castings, which belongs to the technical field of casting. Background technique [0002] With the development and promotion of titanium alloy casting technology, titanium alloy has been promoted from the high value-added aerospace field to the low-cost ground transportation field, and the ground transportation field has strict requirements on the cost performance of titanium alloy. In order to meet the needs of the market, it is one of the paths for the development of titanium alloy casting technology to break through the original high-cost gating system design concept, improve the utilization rate of pouring metal, and reduce the alloy cost of castings. [0003] Due to the high chemical activity of titanium alloy, its casting is usually smelted in a vacuum consumable shell furnace. The existing vacuum consumable congealing furnace smelting uses the smelting conditions of th...
