Inorder to save this part of the raw material, it needs to install a set of alloysieving device in the steelmaking field before the alloy into the steelmakinghopper, make the qualified alloy powder into the hopper, collect the screenedout alloy powder in a special container, and then sieved the alloy powder again,screened out 3mm ~ 5mm particles and 0 ~ 3mm alloy powder. Remelting 3mm ~ 5mm alloy particles in the intermediate frequencyelectric furnace, because in the remelting process is not adding any othermaterials, maintaining the original composition of the manganese silicon. Aftertesting, its physical and chemical indicators are in line with wholesale drill bits the manganesesilicon indicators? requirements. Then press-molded and processed the 0~3mm alloy powder into regeneratingsilicon manganese ball by certain quality requirements, sent to the steelmakinginstead of manganese-silicon for recycling after processing.

Metal powder supplier studied the three alloys for steelmaking -- high-carbon ferromanganese,manganese silicon alloy, ferrosilicon. After screening, made renewablemanganese silicon balls products, the sieved out powder of high-carbonferromanganese and ferrosilicon powder used as adjustment component of majorraw materials, the main ingredient of the product is Mn55%-60% Si17%-21%, othersremain the same with the original alloy composition, particle size is 20mm~~60mm, through production test and achieved success,can completely replace the same amount of manganese silicon alloy, not only canreduce the environment pollution, enhance enterprises? capacity for sustainabledevelopment, achieve circular economy, can also reduce costs annually.

Regeneration manganese silicon ball?s mainingredient physical and chemical indicators: manganese powder55%-60%, silica fume 17%-21%, while the recovered silicon manganese alloy, highcarbon ferromanganese, ferrosilicon alloy powder determined by laboratorytests, the main component of manganese, silicon is unstable, in manganesesilicon alloy powder, manganese powder is generally in the range of 54%-60%, silicafume is 13%-19%; manganese in high carbon manganese ferroalloy powder isgenerally fluctuate in the region of 58%-63%; silicon powder in ferrosilicon isgenerally fluctuate in the region of 72% - 78%; other ingredients were stable.Seen from the test results of all kinds of alloy powder, any kind of alloypowder processing directly are difficult to achieve the technical standards ofthe research results. Therefore, choose manganese-silicon alloy powder as themain raw material for processing, high-carbon ferromanganese, ferrosiliconalloy powder as the adjustment of the raw material for silicon and manganesecomponents.

Steel smelting, consider to the low densityalloy sphere, in order to prevent the intractable problem like agglomeratingand can not melting in deoxy alloying process, require the use alloy ballsmelting steel grades are as follows: the refined steel species (Refiningspecies? production cycle is longer, can fine-tune alloy in the refiningfurnace), unrefined low alloy steel kinds, such as Q235B (due to the smallamount of alloy, in deoxy-alloying process does not appear intractable issuessuch as alloy ball agglomerate). The usage mode is the same with the conventionalalloys, alloy ball instead of manganese silicon alloy dth hammer adding in the steel tappingprocess after furnace, the added amount of other alloys and deoxidizer is normallyadding according to the requirement.
