阿里巴巴不锈钢铸造的工艺控制有哪些？
What are the process controls for stainless steel casting?
1、以很少的电耗将固体炉料熔化为均匀的液体，炉料熔化的同时，熔池中也发生各种各样的物化反应，主要有元素的挥发和氧化、钢液的吸气、热量的传递与散失以及夹杂物的上浮等。因此不锈钢铸造熔化期提前造渣覆盖于钢液面上，既可减少散热，减少钢液的吸气量，又可促使夹杂物的上浮等，磷是钢中的不好的元素，在冶炼过程中，要尽量降低不锈钢铸造中的磷含量。
1. Solid furnace materials are melted into a uniform liquid with minimal electricity consumption. At the same time as the furnace materials melt, various physicochemical reactions occur in the molten pool, mainly including the volatilization and oxidation of elements, the suction of molten steel, the transfer and dissipation of heat, and the floating of inclusions. Therefore, during the melting period of stainless steel casting, slag is formed and covered on the steel surface in advance, which can reduce heat dissipation, reduce the suction amount of the steel liquid, and promote the floating of inclusions. Phosphorus is a bad element in steel, and during the smelting process, the phosphorus content in stainless steel casting should be minimized as much as possible.
2、钢液脱氧好，有利于脱硫，且化学成分稳定，不锈钢铸造元素的收得率也高，因此不锈钢铸造脱氧是还原期精炼操作的关键环节，氧化期任务完成后，应快扒净全部氧化渣，如果氧化渣不扒净，在还原期不锈钢铸造就会出现回磷。
2. The deoxygenation of steel liquid is good, beneficial for desulfurization, and the chemical composition is stable. The recovery rate of stainless steel casting elements is also high. Therefore, deoxygenation of stainless steel casting is a key link in the refining operation during the reduction period. After the completion of the oxidation period task, all the oxidation slag should be quickly cleaned. If the oxidation slag is not cleaned, phosphorus will return to the stainless steel casting during the reduction period.
3、不锈钢铸造氧化期脱碳过程产生的CO或（CO+CO2）气泡，有吹氧时来不及参加反应的氧气泡和有目的地往熔池中直接吹入惰性气体或CO气体而形成的气泡上升与逸出，使熔池产生沸腾，为氢和氮的去掉创造条件。
3. The CO or (CO+CO2) bubbles generated during the decarbonization process of stainless steel casting during the oxidation period, oxygen bubbles that cannot participate in the reaction during oxygen blowing, and bubbles formed by purposefully blowing inert gas or CO gas directly into the molten pool rise and escape, causing the molten pool to boil and creating conditions for the removal of hydrogen and nitrogen.
