Abstract

The invention provides a non-oriented electrical steel for frequency conversion air conditioner and its manufacturing method. , [Si]2.80%‑3.4%, [Al]0.20%‑1.20%, [N]≤0.0025%, [Sn]0.01‑0.10%, the balance is Fe and unavoidable residual elements; manufacturing method: steelmaking , continuous casting, heating, hot rolling, normalization, pickling, cold rolling, annealing, cooling and coating; the thickness of the product of the present invention is 0.25-0.30mm, and the iron loss of the product is P 1.5 / 50 ≤2.15W / kg, magnetic polarization J 5000 ≥1.65T, fast magnetization speed, low iron loss, suitable for the working conditions of inverter air conditioner compressors, can reduce the volume and weight of inverter air conditioners, reduce power consumption, and save resources and energy.

Description

Technical field[0001]The present invention belongs to the field of alloy smelting, and more particularly to a variable-conversion air conditioner without oriented electrical steel and a manufacturing method thereof.Background technique[0002]No longer taking the process of long, process complex, and has more influencing factors of product quality. In particular, the compressor of the inverter air conditioner is frequently used, and the frequency of use of the process is large, the working conditions are complex, and the electromagnetic properties and thickness of the non-replacement electrician steel is high.[0003]The application number disclosed on July 20, 2011 is 2011110008574.x "a method for manufacturing cold rolling without retroffall air conditioner", the main chemical component [Si] 0.5% -1.0%, [Al] 0.1-0.5 %, Product iron damage P10 / 400≤25W / kg, P10 / 1000≤ 1110 W / kg, its annealing temperature is low temperature of 660-690 ° C, and does not remove carbon. The finished carbo...
