Embodiment Construction

[0019] Such as figure 1 , figure 2 As shown, the semi-continuous casting crystallizer for near-net-shape aluminum alloy ingots includes a crystallizer body 2 and a thermal insulation roof 1. 2 is provided with an oil-gas distribution ring 4, and the oil-gas distribution ring 4 is evenly distributed with gas injection holes 6 and oil injection holes 5 along the circumferential direction. The crystallizer body 2 includes a cooling water cavity and a water spray structure connected with the water cavity. The water spray structure is a non-equal width water gap structure 8. The crystallizer body includes a cooling water cavity and a water spray structure connected with the water cavity. The water spray structure is a non-equal width water gap structure, so that The cooling water flow rate is non-equivalent distribution, which varies from 0 L / min×mm to 0.95 L / min×mm, and a water separator 7 is provided in the cooling water cavity.

Abstract

The invention relates to a semi-continuous casting crystallizer for an aluminum alloy near net shape cast ingot. The semi-continuous casting crystallizer comprises a crystallizer body and a thermal insulation hot top, wherein the thermal insulation hot top is arranged on the crystallizer body, an oil-gas distribution ring is arranged between the thermal insulation hot top and the crystallizer, gas injection holes and oil injection holes are uniformly distributed in the oil-gas distribution ring along the circumferential direction, the crystallizer body comprises a cooling water cavity and water spray structures communicated with the water cavity, the water spray structures are water seam structures with unequal widths, so that the cooling water flow in the circumferential direction of the crystallizer is a non-equivalent value. According to the crystallizer, liquid metal can be restrained, so that the liquid metal is condensed to a required shape of the cast ingot, and the cast ingot has a smooth surface and consistent quality to meet the dimensional requirements on subsequent thermal forming of the cast ingot. The cast ingot has stable forming condition, smooth surface and no defects, such as a drawing stamp and a gap.

Description

technical field [0001] The invention relates to a semi-continuous casting crystallizer for aluminum alloy near-net-shape ingots, belonging to the technical field of aluminum alloy semi-continuous casting. Background technique [0002] At present, the shape of conventional aluminum alloy ingots is mostly round or rectangular. Round ingots are mainly used for subsequent extrusion into various shapes of profiles. Flat ingots, namely rectangular ingots, are mainly used for rolling into plates of required thickness. Tapes and foils. The shape of the near-net-shape aluminum alloy ingot is different from the conventional aluminum alloy round ingot or flat ingot. It mainly designs the shape of the ingot according to the shape of the follow-up product, and then prepares the shape by low-cost semi-continuous casting. The near-net-shape aluminum alloy ingot whose size is close to the shape of the final product is used for subsequent direct forging of aluminum alloy products. [0003]...
