Description

An apparatus for manufacturing oxidized molybdenum forming brick}

The present invention relates to an apparatus for producing molybdenum oxide-formed briquettes. More specifically, molybdenum oxide contained in order to increase its rigidity when manufacturing special steel is manufactured as a molding briquette to minimize the loss of raw materials and to be rigidly molded and transported. And it relates to a manufacturing apparatus of molybdenum oxide-formed briquettes that can be easily stored, can be produced in large quantities within a short time according to a continuous working process to significantly reduce the price of the product itself.

Generally, it is an alloying element that is a dissolution additive to increase the strength of special steel such as X-ray tube, resistance wire for electric furnace, stainless steel and SCM steel, and has high hardness, corrosion resistance, and molybdenum that can withstand a considerable temperature. (molybdenum) was added to prepare a special steel.

However, the above-mentioned molybdenum is molybdenum oxide, which is mostly formed in powder form, and since a large amount is scattered due to heat and oxygen supply emitted from the blast furnace at the time of input, it is impossible to constantly adjust the component ratio of the special steel to be manufactured. In order to solve this problem, molybdenum oxide in powder form was mixed with sodium carbonate, heated to about 700 ~ 900 ° C. in a rotary furnace, melted, and then cooled again, and then crushed to have a predetermined size. Was prepared and used.

However, since the molybdenum metal is Na ₂ M ₀ O ₄ (Sodium Molybdate) is about 15% bonded to the molybdenum metal, it is impossible to reduce the molybdenum metal in the steel furnace, so that the yield of the molybdenum metal component is significantly lowered. In the process of crushing, powder is easily mixed and scattered during operation, and melted by applying high heat, thereby causing loss due to sublimation of the molybdenum component.

In addition, since the use of additives such as sodium carbonate, saltpeter, etc., the production cost is high, and the price of the product itself is also expensive.

On the other hand, there was also a method of molding molybdenum oxide in the form of briquettes in order to solve the problems in the molten briquettes as described above, which has a powder form of molybdenum oxide and water binder (water grass) as a binder A method of injecting a mixture of water into the mold and then compressing the same by applying a constant pressure was also devised.

However, since the mixture must be molded by pressing the mixture into the mold one by one, the productivity is remarkably decreased, and thus a mass production has not occurred.

In addition, in the pressing process as described above, the adhesive force between the mixture is weak, so as to apply excessive pressure in order to prevent the collapse, resulting in a high wear rate of the mold and a failure rate of the mechanical device, the product price is also very expensive problem.

Accordingly, the present invention has been made to solve the conventional problems as described above, the purpose is to produce molybdenum oxide as a molding briquette to minimize the loss of raw materials and to form a solid and easy to transport and storage, It can be produced in a large amount within a short time according to the continuous work process to reduce the price of the product itself.

The present invention for achieving the above object is a mixing unit for mixing the molybdenum oxide raw material in the form of water and starch and powder while supplying steam; A first conveying portion configured to convey the mixture discharged through the mixing portion to a known conveyor; A vibrator for filtering the mixture passed through the first conveying unit into a uniform powder state; A second transfer part configured to transfer the powdered mixture discharged through the vibrator to a known conveyor; It characterized in that it comprises a molding portion for receiving the mixture in the form of powder through the second conveying portion and compression molding in a predetermined form.
