Abstract

The invention belongs to the field of building formworks, and particularly relates to a magnesium alloy material for a building formwork and a preparation method. The magnesium alloy material comprises the following raw materials in percentage by mass: 0.25-0.6% of Ca, 0.25-0.5% of Y, 0.35-0.8% of Sn, 0.1-0.5% of Sr and the balance of AZ41. The preparation method comprises the following step: S1, melting, specifically, carrying out heating melting on magnesium alloy in a clean crucible to prepare magnesium liquid. According to the magnesium alloy material, the condition that a refiner is added in the refining process is improved, the refining effect of the refiner is improved, slag is sufficiently dredged in the two refining processes, the magnesium liquid is cleaner, flux slag at the bottom of the crucible is reduced, the cast product is cleaner, a flux mixture is not easily brought in, the corrosion resistance of the product is improved, and the preparation method is simple in process, reliable, economical and easy to apply and popularize.

Description

technical field [0001] The invention relates to the technical field of building templates, in particular to a magnesium alloy material for building templates and a preparation method. Background technique [0002] Building formwork is the main tool for the construction of concrete structures. It usually plays the role of support and protection in the pouring process. It consumes a lot in construction projects. Formwork technology directly affects the quality and cost of construction projects. Therefore, it is the key to promoting the progress of construction technology. an important content. In recent years, my country's real estate industry has developed rapidly, and building templates have also developed rapidly. [0003] At present, the materials of commercial building formwork mainly include: wooden formwork, which is light in weight and good in versatility; but its mechanical properties are very limited, and it is easy to break when it is under the pressure of cement, ...
