Chemical analysis of molybdenum iron-molybdenum alloy metal detection

 Detection / Consulting: 180-2871-9376 (Wang Li) QQ: 2419906857 molybdenum iron smelting raw materials mainly for molybdenite (MoS2). Former smelting usually with multiple hearth furnace molybdenum concentrate roasting, get less than 0.07% sulfur roasting molybdenite. Molybdenum iron smelting furnace extrajudicial commonly used. The stove is placed on a sand base of the cylinder, the inner lining brick masonry, with 75 percent of ferrosilicon and silicon aluminum particles as small amounts of reductant. After the charge was added furnace tube, with the upper part of the ignition smelting. In the material surface with an initiator (saltpeter, aluminum or magnesium shavings litter), ignition after a violent reaction, then calm, put slag, furnace tube removal. Molybdenum iron ingots to nest in the sand cooled, sending flush cooling room cooling, and finally crushed finishing. Metal recoveries of 92 to 99%. In the steel industry in recent years, is widely used in place of molybdenum molybdenum iron briquettes. Molybdenum iron smelting method commonly used metal heat. Ferro Molybdenum is a statutory inspection of goods. The main origin of Jilin, Hebei, Jiangsu, Henan, Liaoning, mainly to the United States, the Netherlands and Germany. According to GB3649-2008 provides different molybdenum and molybdenum iron impurity content is divided into three grades, its chemical composition shall conform to Table 6-6-22, the parties to the table column elements For special requirements, supply and demand sides can be separately negotiation. When the demand side, the measured data can be negotiated provided other than the listed elements.
