The steelmaking refining agent is mainly obtained by baking and mixing composition raw materials of calcium oxide, silicon oxide, waste aluminum powder, magnesium oxide, sodium fluoride, carbon tetrachloride, expanded vermiculite, quartz sand, calcium carbide and kaolin according to certain weight parts. The preparation method provided by the invention is simple, the steel solution refining effect is improved through the prepared refining agent, the production flow process is simplified, and the utilization rate of the refining agent is improved.
Description
Technical field
The present invention relates to the non-ferrous metal metallurgy equipment technical field, be specifically related to a kind of steel-making refining agent and preparation method thereof.
Background technology
In the modern steel casting, product structure is complicated to become the main path that reduces production costs with simplified processing technology, has developed various precision casting process for this reason; Advantages such as extrusion process becomes one of main forming method, and it has the production efficiency height, saves starting material, forming part process redundancy is little.Extrusion process develops to high-accuracy direction in recent years, design and produce the raising of technology along with die casting, and the raising of pressure die-casting machine performance, make die casting steel-iron components and other iron and steel precision casting part have close use properties, the iron and steel die cast is just becoming widely used castmethod.
When die casting is produced, the iron and steel liquation solidifies in the die casting die cavity, the iron and steel liquation is in process of setting, the formation hydrogen molecule that hydrogen atom in the iron and steel liquation is spontaneous, the hydrogen molecule of spontaneous formation and the bubble that forms for the forming core substrate with the non-metallic inclusion, be mingled with is to cause the major cause that produces defective in the iron and steel die casting, and impurity and the gas of the overwhelming majority come from foundry returns in the iron and steel liquation, as material handle remaining after the die casting, runner, slag trap, waste product spare etc., so when Manufacture Of Iron And Steel By Melting, the refining treatment of iron and steel liquation is essential, in recent years, people pay attention to development of new steel-making refining agent and refining treatment method all the more.
