Problems solved by technology
Amorphous alloy magnetic strips have strict requirements on preparation conditions, and the cooling rate must reach more than 100,000 degrees Celsius per second. Usually, the thickness of amorphous alloy magnetic strips is less than 0.1 mm, which requires controlling the flow rate of the alloy melt to avoid If the flow rate is too fast or unstable, the thickness of the amorphous alloy magnetic strip will be too large, and the cooling time will affect the performance of the amorphous alloy magnetic strip.

The invention discloses a closed type amorphous strip casting mechanism capable of controlling flow speed conveniently. The closed type amorphous strip casting mechanism comprises an alloy material airtight melting furnace, an amorphous alloy solution casting ladle and an amorphous alloy solution casting runner. One end of the amorphous alloy solution casting runner is connected with the alloy material airtight melting furnace. The other end of the amorphous alloy solution casting runner is connected with the amorphous alloy solution casting ladle. The side wall of the amorphous alloy solution casting ladle is provided with a horizontal protruded sampling monitoring pipe communicating with the amorphous alloy solution casting ladle, and a constant-temperature heating electric resistance wire is arranged on the outer side of the amorphous alloy solution casting ladle and is connected with an input power regulator. According to the closed type amorphous strip casting mechanism, the flow speed of alloy melted liquid can be controlled accurately, the conditions that the flow speed is too large or unstable, consequently the thickness of an amorphous alloy magnetic strip is too large, cooling is not conducted in time, and performance of the amorphous alloy magnetic strip is influenced are avoided.
Description
technical field [0001] The invention relates to the technical field of amorphous alloy material processing equipment, in particular to a closed-type amorphous strip material pouring mechanism which is convenient for controlling the flow rate. Background technique [0002] Amorphous alloy magnetic strip is an alloy material composed of iron, silicon, boron and other elements, and its high saturation magnetic induction, magnetic permeability, excitation current and iron loss are superior to silicon steel sheet in various aspects. Amorphous alloy magnetic strips are usually prepared by the single-roll rapid quenching method: first, the raw materials containing the constituent elements of the amorphous alloy need to be put into the furnace for melting and calcination, and then the fully fused amorphous alloy melt is poured into the rapid quenching method. On a rotating cooling roll with a low surface temperature, the molten amorphous alloy material contacts the cooling roll and ...
