Embodiment 1

[0034] According to the composition ratio of AZ31B alloy, take 90Kg of magnesium ingot (industrial pure magnesium), 2750g of industrial pure aluminum, and 910g of pure zinc, put them into a melting furnace for melting at 706°C, and add 1.0% of covering agent and a small amount of common Protected by argon to prevent burning in contact with air, the mass percentage of the covering agent is: 55% magnesium chloride, 15% potassium chloride, 18% sodium chloride, and 12% calcium chloride. After the material is melted, add 0.6% scouring agent on the surface of the melt to remove slag and degas by stirring. The mass percentage of scouring agent components is: 55% magnesium chloride, 15% potassium chloride, 20% sodium chloride, Calcium chloride 5%, calcium fluoride 5%. While the magnesium alloy is being refined, heat the front box and the flow channel to 600°C, and keep it warm for 20 minutes after the magnesium alloy smelting is completed, so that the temperature of each part of the m...

Abstract

The invention discloses a method for preparing a magnesium alloy strip by multi-energy field casting and rolling. In the present invention, a layer of covering agent is evenly sprinkled on the top of the prepared magnesium alloy, and heated and melted under the protection of argon; after the material is melted, a certain amount of scouring agent is added to the surface of the melt, and stirring is carried out to remove slag and degas to complete scouring In the process, the refined and static magnesium alloy melt is introduced into the roll gap of the electromagnetic field casting and rolling unit through the heated runner and front box, and is stirred by the electromagnetic field, vibration shock, forced cooling of the roll, and rolling deformation. , strengthen the heat transfer, mass transfer and energy conversion in the casting and rolling zone, realize the proliferation of crystal nuclei, and change the solidification behavior. The invention successfully applies the electromagnetic field to the casting and rolling process of the magnesium alloy, and the prepared magnesium alloy strip has a smooth surface, neat edges, good structure and mechanical properties, and the whole production process is short, the efficiency is high, and the product cost is low. Good quality, suitable for batch production of magnesium alloy strips.

Description

technical field [0001] The invention belongs to the field of metal material processing, and in particular relates to an electromagnetic and ultrasonic casting-rolling preparation method for magnesium alloy strips, which can realize industrial production, and the method can be widely used in the preparation of magnesium alloy strips. Background technique [0002] Magnesium is one of the commonly used metal elements with the most abundant reserves in the world. It is the sixth most abundant metal element in the earth’s crust, with a content of about 2.3%. It is also the third most abundant metal element in seawater, with a total amount of about 0.14% of seawater , from an average of 1m 3 More than 1kg of metallic magnesium can be extracted from seawater, and the magnesium content in salt lakes is also very high. The abundant reserves of magnesium resources and the excellent comprehensive properties of magnesium alloys such as high specific strength, specific stiffness, wear r...
