技术领域 technical field
本实用新型涉及一种铝合金近终形铸锭用半连续铸造结晶器，属于铝合金半连续铸造技术领域。 The utility model relates to a semi-continuous casting crystallizer for near-net-shape casting of aluminum alloys, which belongs to the technical field of semi-continuous casting of aluminum alloys.
背景技术 Background technique
目前常规的铝合金铸锭形状多为圆形或矩形，圆铸锭主要用于后续挤压成各种形状的型材，扁铸锭即矩形铸锭主要用于轧制成所需厚度的板、带、箔材。近终形铝合金铸锭形状不同于常规的铝合金圆铸锭或扁铸锭，它主要是根据后续产品的形状来设计铸锭的外形尺寸，然后采用低成本半连续铸造的方式制备出形状尺寸与最终产品外形接近的近终形铝合金铸锭，供后续直接锻造出铝合金产品。 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.
结晶器是制备铝合金锭坯的关键和主要设备，它往往由金属组成一件内部存放冷却循环水的密闭箱体来提供液态金属的冷却并约束其凝固成型。在铸锭制备开始阶段，引锭底座与结晶器构成一个底部封闭的空间。铸造开始后，液态金属流入结晶器内部并保持一定高度，结晶器通入一定量的冷却循环水。在冷却水的作用下，液态金属与结晶器内壁接触并逐渐凝固成一薄层凝固壳，随着引锭底座的下移，整个铸锭逐渐接触到结晶器内部的冷却水并在冷却水的作用下逐渐凝固成型。因此，结晶器不仅起着冷却金属铸锭，使其凝固成型，同时它还起着约束液态金属，使整个铸锭顺利凝固成需要形状的作用。由此可见，铸锭形状尺寸的差异以及表面质量的好坏，其约束成型的铸造结晶器设计起到至关重要的作用。 The crystallizer is the key and main equipment for the preparation of aluminum alloy ingots. It is often composed of metal to store a closed box with cooling circulating water inside to provide cooling for liquid metal and restrict its solidification and forming. In the initial stage of ingot preparation, the dummy base and the crystallizer form a space with a closed bottom. After the casting starts, the liquid metal flows into the crystallizer and maintains a certain height, and a certain amount of cooling circulating water is passed into the crystallizer. Under the action of cooling water, the liquid metal contacts the inner wall of the crystallizer and gradually solidifies into a thin layer of solidified shell. As the dummy base moves down, the entire ingot gradually contacts the cooling water inside the crystallizer and under the action of cooling water Gradually solidify and form. Therefore, the crystallizer not only plays the role of cooling the metal ingot to make it solidify and form, but also plays a role in confining the liquid metal so that the entire ingot can be solidified into the desired shape smoothly. It can be seen that the difference in the shape and size of the ingot and the quality of the surface quality play a crucial role in the design of the casting crystallizer that constrains the molding.
随着铝加工材产品质量要求的不断提高，铝合金结晶器经历了铜板结晶器、矮槽结晶器、热顶结晶器以及后续先进的气滑结晶器和低液位铸造结晶器的发展阶段，这些先进结晶器的投入使用为铝合金铸锭质量带来了革命性影响，不仅使铸锭内部冶金质量显著提高，而且铸锭表面质量更是实现了飞跃式进步，铸锭偏析层厚度降低，铣面量减少，综合生产效率显著提高。 With the continuous improvement of product quality requirements for aluminum processing materials, aluminum alloy molds have experienced the development stages of copper plate molds, low-trough molds, hot-top molds, and subsequent advanced air-slip molds and low-level casting molds. The use of these advanced crystallizers has brought a revolutionary impact on the quality of aluminum alloy ingots. Not only has the internal metallurgical quality of the ingots been significantly improved, but the surface quality of the ingots has also achieved a leap forward, and the thickness of the segregated layer of the ingots has decreased. The amount of face milling is reduced, and the overall production efficiency is significantly improved.
然而，目前铝合金铸造结晶器主要以制备圆铸锭和扁铸锭为主，未见能够铸造不规则铸锭形状的结晶器结构及组成相关报道。 However, at present, aluminum alloy casting molds are mainly used to prepare round ingots and flat ingots, and there are no reports on the structure and composition of molds capable of casting irregular ingot shapes.

具体实施方式 Detailed ways
如图1、图2所示，铝合金近终形铸锭用半连续铸造结晶器，包括结晶器本体2和保温热顶1，保温热顶1置于结晶器本体2之上，在保温热顶1与结晶器本体2之间设有油气分配环4，油气分配环4上沿周向分别均匀分布有注气孔6和注油孔5，结晶器本体2包括冷却水腔体以及与水腔相连通的喷水结构，喷水结构呈非等宽式水缝结构8，结晶器本体包括冷却水腔体以及与水腔相连通的喷水结构，喷水结构呈非等宽式水缝结构，使沿结晶器周向冷却水流量非等值分布，在0 L/min×mm~0.95 L/min×mm范围变化，冷却水腔体内设有分水器7。 As shown in Figure 1 and Figure 2, the semi-continuous casting crystallizer for near-net-shape aluminum alloy ingots includes a crystallizer body 2 and a thermal insulation roof 1, and the thermal insulation roof 1 is placed on the crystallizer body 2. There is an oil-gas distribution ring 4 between the top 1 and the crystallizer body 2. The oil-gas distribution ring 4 is evenly distributed along the circumferential direction with gas injection holes 6 and oil injection holes 5. The crystallizer body 2 includes a cooling water cavity and is connected to the water cavity. A common water spray structure, 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, The flow rate of cooling water along the circumferential direction of the crystallizer is not equivalently distributed, and varies in the range of 0 L/min×mm to 0.95 L/min×mm, and a water separator 7 is provided in the cooling water cavity.
通过非等宽式水缝结构8使冷却水流量沿铸锭周边呈非等值分配，即依照铸锭外形尺寸，通过调整结晶器水缝宽度使冷却水流量线密度沿铸锭周边在0 L/min×mm~0.95 L/min×mm范围变化。结晶器依靠水缝或喷水孔方式实现冷却水流量线密度沿铸锭周边变化。 The non-equal-width water gap structure 8 makes the cooling water flow non-equivalent distribution along the periphery of the ingot, that is, according to the overall size of the ingot, by adjusting the width of the crystallizer water gap, the linear density of the cooling water flow along the periphery of the ingot is at 0 L /min×mm~0.95 L/min×mm range changes. The mold relies on water slots or water spray holes to realize the change of cooling water flow line density along the periphery of the ingot.
结晶器采用保温热顶和冷却壁凝固铸锭，为提高近终形铸锭的表面质量，控制偏析层厚度，设计有油气分配环4，起到提高铸锭表面质量的作用，其中，注油孔5的宽度为0～2.5mm，高度为0～1.6mm，相邻两注油孔的间距为1～5mm，注气孔6的宽度为0～3.9mm，高度为0～2.8mm，相邻两注气孔的间距为1～6mm，注油孔设计为将本体打通的油孔。在铸造过程中，压缩空气和润滑油分别通过注气孔6和注油孔5进入油气分配环4，其中压缩空气与熔体压力形成动态平衡，在保温热顶下沿推动金属熔体，使其形成弯月面，降低金属溶体对结晶器内衬的静压力。润滑油经出油孔后在结晶器内壁形成一薄层润滑油膜，起到连续润滑结晶器内表面，降低铸锭表面与结晶器间摩擦力的作用。在铸造过程中近终形结晶器采用油气分配环连续供压缩空气和润滑油后，铸锭表面质量显著提高。也可根据铸锭表面质量要求，铸造过程中可选择同时通润滑油和压缩空气，或者只连续注油润滑，不通压缩空气，或者同时不通润滑油和压缩空气。 The crystallizer adopts heat-insulating hot top and cooling wall to solidify the ingot. In order to improve the surface quality of the near-net shape ingot and control the thickness of the segregation layer, an oil and gas distribution ring 4 is designed to improve the surface quality of the ingot. Among them, the oil injection hole The width of 5 is 0-2.5mm, the height is 0-1.6mm, the distance between two adjacent oil injection holes is 1-5mm, the width of air injection hole 6 is 0-3.9mm, and the height is 0-2.8mm, and the distance between two adjacent injection holes is 0-2.8mm. The spacing of the air holes is 1-6mm, and the oil injection hole is designed as an oil hole to open the body. During the casting process, compressed air and lubricating oil enter the oil and gas distribution ring 4 through the air injection hole 6 and the oil injection hole 5 respectively, in which the compressed air and the melt pressure form a dynamic balance, and the metal melt is pushed along the lower edge of the thermal insulation heat to form a The meniscus reduces the static pressure of the molten metal on the lining of the mold. After the lubricating oil passes through the oil outlet hole, a thin layer of lubricating oil film is formed on the inner wall of the crystallizer to continuously lubricate the inner surface of the mold and reduce the friction between the surface of the ingot and the mold. After the near-net shape crystallizer is continuously supplied with compressed air and lubricating oil by the oil-gas distribution ring during the casting process, the surface quality of the ingot is significantly improved. According to the surface quality requirements of the ingot, you can choose to pass lubricating oil and compressed air at the same time during the casting process, or only continuous oil lubrication without compressed air, or not pass lubricating oil and compressed air at the same time.
保温热顶1布置于结晶器本体2上方，起保持熔体温度、增加熔体流动性、提高金属补缩能力的作用。结晶器本体2由轧制变形的铝合金板材或紫铜板材经机加工而成，铸造过程中，结晶器本体2内衬直接接触铝熔体，并提供近终形铸锭的一次冷却。为保证结晶器内部的冷却水分布均匀，避免因结晶器本体内腔形状不规则和进水口位置不对称而导致的冷却水流量变化，在结晶器内部设计有分水器7，其作用是保持腔体内水位高度、均匀分配水腔内部冷却水流量的目的。 The heat preservation hot roof 1 is arranged above the crystallizer body 2 to maintain the temperature of the melt, increase the fluidity of the melt, and improve the metal feeding capacity. The crystallizer body 2 is machined from a rolled and deformed aluminum alloy plate or red copper plate. During the casting process, the inner lining of the mold body 2 directly contacts the aluminum melt and provides primary cooling of the near net shape ingot. In order to ensure the uniform distribution of cooling water inside the crystallizer and avoid the change of cooling water flow rate caused by the irregular shape of the inner cavity of the crystallizer body and the asymmetrical position of the water inlet, a water separator 7 is designed inside the crystallizer, and its function is to maintain The height of the water level in the cavity and the purpose of evenly distributing the cooling water flow in the water cavity.
因近终形结晶器内腔形状不规格，因此金属熔体在内腔各个位置的凝固速率不一致，某些位置甚至受形状差异影响而导致凝固速率差别过大。为保证铸造过程的顺利进行，采用非等宽式水缝，沿铸锭周边依靠水缝宽度调节冷却水流量值，实现冷却水流量沿铸锭周边呈非等值分配。根据冷却水流量的变化来控制近终形铸锭整体的冷却强度和凝固收缩趋势，进而实现顺利铸造成型。 Due to the non-standard shape of the inner cavity of the near net shape crystallizer, the solidification rate of the metal melt at various positions in the inner cavity is inconsistent, and some positions are even affected by the difference in shape, resulting in an excessive difference in solidification rate. In order to ensure the smooth progress of the casting process, non-equal width water gaps are adopted, and the cooling water flow value is adjusted by the width of the water gap along the periphery of the ingot, so as to realize the unequal distribution of the cooling water flow along the periphery of the ingot. According to the change of the cooling water flow rate, the overall cooling intensity and solidification shrinkage trend of the near-net-shape ingot are controlled, so as to realize smooth casting.
采用结晶器不仅能够约束液态金属，使其凝固成所需要的铸锭形状，而且能够确保铸锭表面光滑、质量一致，满足铸锭后续热成型的尺寸要求。 The use of a crystallizer can not only constrain the liquid metal and solidify it into the desired shape of the ingot, but also ensure that the surface of the ingot is smooth and of consistent quality, meeting the dimensional requirements of the subsequent hot forming of the ingot.
首先根据产品形状，考虑热变形要求，设计外形相近的铸锭外形尺寸，考虑铸锭的凝固收缩量后设计近终形结晶器形状以及保温材形状。保温材布置于结晶器本体上方，起到保持金属液温度并在结晶器上方维持一定金属液体高度，提高熔体的流动性和冲型性的作用。 First, according to the shape of the product, considering the requirements of thermal deformation, design the dimensions of the ingot with a similar shape, and design the shape of the near-net mold and the shape of the heat preservation material after considering the solidification shrinkage of the ingot. The insulation material is arranged above the mold body to maintain the temperature of the molten metal and maintain a certain height of the molten metal above the mold, improving the fluidity and punchability of the melt.
根据设计的近终形铸锭形状尺寸，通过调整结晶器周向冷却水作用范围和强度来调整铸锭的整体冷却强度，进而控制近终形铸锭不同位置的凝固收缩量，实现整根近终形铸锭的均匀收缩变形。因近终形铸锭形状变化，铸锭各个位置的冷却强度差异较大，与传统的圆铸锭和扁铸锭结晶器不同，近终形结晶器冷却水流量必须依照铸锭位置的改变而沿结晶器周向调整，否则将导致铸锭某些位置产生过度收缩，增大铸锭表面与结晶器内壁的摩擦力，导致铸锭开裂或表面撕痕，无法实现顺利成型。因此，本结晶器采用非等宽式水缝设计来调整铸锭不同位置的冷却强度值，进而调整近终形铸锭整体的凝固收缩量。 According to the designed shape and size of the near-net-shape ingot, the overall cooling intensity of the ingot is adjusted by adjusting the range and strength of the circumferential cooling water in the crystallizer, and then the solidification shrinkage at different positions of the near-net-shape ingot is controlled, and the whole near-net-shape ingot is realized. Uniform shrinkage deformation of the final shape ingot. Due to the change of the shape of the near net shape ingot, the cooling intensity of each position of the ingot is quite different. Unlike the traditional round ingot and flat ingot mold, the cooling water flow rate of the near net shape mold must be adjusted according to the change of the position of the ingot. Adjust along the circumference of the mold, otherwise it will cause excessive shrinkage in certain positions of the ingot, increase the friction between the surface of the ingot and the inner wall of the mold, and cause cracks or surface tears in the ingot, making it impossible to achieve smooth molding. Therefore, the crystallizer adopts non-equal width water gap design to adjust the cooling intensity value at different positions of the ingot, and then adjust the overall solidification shrinkage of the near net shape ingot.
此外，为提高铸锭的表面质量，提高锻件加工成材率，设计油气分配环。在使用过程中根据工艺要求设定油气量添加量的范围。若对铸锭表面质量要求严格，可选择同时连续供润滑油和压缩空气。结晶器连续供润滑油气介质后，铸锭表面光滑、稳定，偏析层厚度能够控制在小于0.9mm。 In addition, in order to improve the surface quality of ingots and improve the yield of forgings, an oil and gas distribution ring is designed. Set the range of oil and gas addition amount according to process requirements during use. If the surface quality of the ingot is strictly required, you can choose to supply lubricating oil and compressed air continuously at the same time. After the crystallizer is continuously supplied with lubricating oil and gas medium, the surface of the ingot is smooth and stable, and the thickness of the segregation layer can be controlled at less than 0.9mm.
