冶金炉料 煅烧石油焦增碳剂 石油焦增碳剂采用石油焦煅烧提纯等加工而成,外观成圆粒或多棱形。其特点高碳、低硫,低灰是冶金化工、机械、电力等行业理想的加碳材料和反应中间体,得到广泛应用。 煅后石油焦是增碳剂的一种,所谓煅后石油焦就是石油焦经过1300度的高温处后,排除石油原焦中的挥发分和硫等杂质,把固定碳提高并稳定在98.5%左右,硫在0.5左右,但是煅后石油焦是没有经过石墨化(石墨化的温度是3000度)的石油焦,它的密度比较紧凑,不容易分解,所以使用起来吸收率就会低一些,而且分解的速度也是慢一些。 原油经常压蒸馏或减压蒸馏得到的渣油及石油沥青,都可以作为制造石油焦的原料,再经焦化后就得到生石油焦。生石油焦的产量大约不到所用原油量的5%,生石油焦中的杂质含量高,不能直接用作增碳剂,必须先经过煅烧处理。 测试数据 参数 测试数据 参数 硫含量 0.5-3 挥发分 12-18 灰分 0.3-1.2 水分 ≤3 硅含量 ≤0.08 铁含量 ≤0.08 真密度 2.08-0.13 粉焦量 25% 石油焦增碳剂的使用方法: 将增碳剂置于电炉中下部位。即在炉内先安放小部分铁料将其熔化(或上炉剩余少量铁水)后,加入所需要的金属炉料,将增碳剂全部压入铁水中,使增碳剂与铁水充分接触。 增碳剂吸收期间要避免铁水的除渣操作,以免增碳剂被随渣带出炉外。 建议回炉料或生铁在增碳剂化清后加入。 铁水出炉前,可将小剂量增碳剂加在铁水表面,作碳量微调用,通过电流的涡流搅拌或人工搅拌使增碳剂溶解吸收。 增硅和增硫应在增碳剂吸收完毕后进行。 Product description: Petroleum coke carbon additives using petroleum coke calcining purification processing, a round or polygonal appearance. Its characteristics of high carbon and low sulfur, low ash is metallurgy, chemical industry, machinery, electric power and other industries ideal with carbon materials and reaction intermediates, widely used. Calcined petroleum coke is carburizing agent a, the so-called calcined petroleum coke is petroleum coke after 1300 degrees of high temperature, excluding petroleum raw coke in the volatile matter and sulfur and other impurities, the fixed carbon increased and stabilised at 98.5%, sulfur at 0.5%, but calcined petroleum coke is no after graphitization (graphitization temperature is 30 degrees) of the petroleum coke, its density is compact and is not easy to break down, so use it will lower the absorption rate and the rate of decomposition is slower. Preparation process: Crude oil often pssure distillation or vacuum distillation to obtain the residual oil and petroleum pitch, can be used as the raw material for the manufacture of petroleum coke, and then get raw petroleum coke after coking. Students of petroleum coke yield less than about 5% of the volume of crude oil, high impurity content in petroleum coke raw, can not be directly used as a carburizing agent must first undergo a calcination treatment. Using method: The carburant in the middle lower part of furnace. That in the furnace first placed a small part of the iron material melting (or furnace remaining a small amount of hot metal), adding the metal charge, pss the carburant all into molten iron, carbon agent and good contact with the molten iron. Carbon absorption should avoid slag operation except the molten iron, so as to avoid the carburetant with slag is carried out. That returns or pig iron in cleaning after adding carburetant. Before tapping of molten iron, the small dose of carburizing agent is added on the surface of the molten iron, carbon micro call, through the current eddy stirring or artificial mixing so that absorption of carburizing agent is dissolved. By adding sulfur in silicon and carbon absorption after. 宽城绿康活性炭厂 厂 址:河北承德宽城满族自治县 联 系 人:李璐璐 手 机: Q Q:2792770861 邮 箱:2792770861@qq.com 网 址 品名 石油焦增碳剂 固定碳 95(%) 规格 1-3mm 5-20mm 10-20mm(目) 型号 LK-01 水分 ≤0.5(%) 膨胀度 1.06(倍) 筛上物粒度 95(%) 灰分 <0.5 挥发分 <0.5(%) 筛下物粒度 5(%) 硅含量 ≤0.08 铁含量 ≤0.08
