Introduction suitable for machining magnesium alloy sheet, strip, tube, rods, profiles and wire and other products and the alloy ingot and slab. 1, the implementation of standards: ASTM B90 / B90M 2, process: Spirit of semi-continuous casting production of magnesium alloy billets casting magnesium alloy semi-continuous casting magnesium alloy compared with traditional, semi-continuous casting magnesium alloy finer in the organization, the composition is more uniform, internal denser, than the traditional casting magnesium alloy having high strength and higher elongation. 1, by pipetting and secondary refining, high purity, low impurity, magnesium liquid pouring directly from the holding furnace heated to rapid crystallization, improved internal magnesium rod microstructure of dense, compact internal crystalline more reasonable physical performance is also greatly enhanced than conventional cast products. 2, the flux slag forming products tend to be more content to zero, semi-continuous casting magnesium alloy using the emerging inert gas protection devices, allowing flux slag content is greatly reduced, improving product quality. Traditional process, the smelting process is completely exposed to the air, and so can only rely on the flux flame retardant material. 3, the surface smooth, clean, no porosity, shrinkage, slag. 4, the length of the flexible random, existing maximum diameter Φ600mm, according to user requirements skinned, cut segments, in addition, can also produce other products with different specifications to meet customer needs. Semi-continuous casting can also pull a variety of magnesium alloy flat bar. 3, magnesium alloy chemical composition of the alloy groups Chemical Composition (mass fraction) /% Mg Al Zn Mn Ce Zr Si Fe Ca Cu Ni Be single other element b MgAlZn AZ31B total margin 2.5-3.5 0.6-1.4 0.2-1.0 ── ── ≤0.08 ≤0.003 ≤0.04 ≤0.01 ≤0.001 ── ≤0.05 ≤0.30 AZ40M margin 3.0-4.0 0.2-0.8 0.15-0.5 ── ── ≤0.10 ≤0.05 ── ≤0.05 ≤0.005 ≤0.01 ≤0.01 ≤0.30 AZ80A margin 7.8-9.2 0.2-0.8 0.12-0.5 ── ── ≤0.10 ≤0.005 ── ≤0.05 ≤0.005 ── ── ≤0.30 AZ91D margin 8.5-9.5 0.45-0.9 0.17-0.4 ── ── ≤0.08 ≤0.004 ── ≤0.025 ≤0.001 0.0005-0.003 ≤0.01 ≤0.30 MgMn M2M margin ≤0.20 ≤0.30 1.3-2.5 ── ── ≤0.10 ≤0.05 ── ≤0.05 ≤0.007 ≤0.01 ≤0.01 ≤0.20 MgZnZr ZK61M margin ≤0.05 5.0-6.0 ≤0.10 ── 0.3-0.9 ≤0.05 ≤0.05 ── ≤0.05 ≤0.005 ≤0.01 ≤0.01 ≤0.30 MgMnRe ME20M margin ≤0.20 ≤0.30 1.32-2.2 0.15-0.35 ── ≤0.10 ≤0.05 ── ≤0.05 ≤0.007 ≤0.01 ≤0.01 ≤0.30 4, Specifications Specifications Remarks Name brand magnesium alloy bar AZ31B ZK61M AZ80A AZ91D M2M ME20M AZ40 casting rod blanks ф93-600 * 4500 are available upon request sawing and heat treatment
