Problems solved by technology
Using this production process to produce corrosion-resistant soft magnetic alloy rods has a long process flow, relatively high production costs, and very difficult production organization, so such enterprises are generally unwilling to produce such products
For other types of small steel mills and township enterprises in China, because their smelting process only uses electric arc furnace or intermediate frequency furnace and other crude steel smelting methods, the product quality is basically difficult to meet the special requirements of magnetic functional materials. Corrosion soft magnetic alloy (ferritic electromagnetic stainless steel) functional bar mostly depends on imports from Germany, Japan, Italy and other countries

The invention relates to a production process for continuous casting anti-corrosion magnetically soft alloy bars with light sections, which comprises the process steps of batching, smelting, continuous casting and hot rolling, wherein during the continuous casting, the temperature of molten steel is controlled within the range of 1,600+ / -20 DEG C in the billet withdrawing production process, the billet withdrawing speed is controlled within the range of between 2 and 2.5 meters / minute, and the billet withdrawing frequency is controlled within the range of between 80 and 120 times / minute; and during the hot rolling, continuous casting circular billets are conveyed to a heating furnace for warming until the temperature reaches 1,050+ / -10 DEG C, and after heat preservation is performed for 30 minutes, the circular billets are subjected to hot rolling. Compared with the prior art, the production process has the characteristics of near-net shaping, short flow of the production process, low production cost, high efficiency, energy conservation, product quality reaching the same level as that of vacuum smelting and the like; and performance indexes of the continuous casting anti-corrosion magnetically soft alloy bars accord with and are partially superior to the standard of similar imported materials at home and abroad, and the similar imported materials can be replaced completely so as to end the situation that the majority of high-quality anti-corrosion magnetically soft alloy (ferrite electromagnetic stainless steel) functional bars in our country depend on import.
Description
technical field [0001] The invention relates to the production of alloy rods in the field of metallurgical continuous casting, in particular to a production process of small-section continuous casting corrosion-resistant soft magnetic alloy rods. Background technique [0002] In recent years, with the continuous development of automatic control technology and remote control technology, various control regulators represented by solenoid valves have become more and more widely used. Moreover, in order to achieve the miniaturization and proportional control of the regulator, the reliability requirements for the corrosion-resistant soft magnetic alloy (electromagnetic stainless steel) functional material will be higher. At the same time, with the high application of processing methods such as high-speed cutting, high precision, and cold forging, the requirements for material properties are developing in the direction of diversification (multiple steel types, multiple specificati...
