Abstract
The utility model relates to a reduction tank for magnesium smelting. The reduction tank for magnesium smelting is characterized in that the reduction tank is a double structure; a lining tank made from silicon nitride or silicon carbide material is sheathed in an outer layer tank body; the wall thickness of the outer layer tank body is 10 to 20 mm; the wall thickness of the lining tank is 10 to 35 mm. The reduction tank for magnesium smelting has the advantages that an inner layer tank body is made from silicon nitride or silicon carbide material having the advantages of good heat-conducting properties, small thermal expansion coefficient, and high compressive strength, and can be used for supporting the outer layer tank body to enable the outer layer tank not to deform, so deforming gas leakage phenomenon is inhibited and the service life of products is ensured; the reduction tank has the advantages of reasonable structural design, high safety, and good temperature and pressure resistance; compared with an old reduction pot, the service life of the reduction tank is improved to more than two times.
Description
The utility model relates to metal melting equipment, relates in particular to a kind of reduction jar that is applicable to that magnesium is smelted.
In the prior art, when magnesium metal smelting, use the reduction jar usually, its cross section is cylindrical, can body is longer, and the material of jar is generally nichrome (high temperature steel), and wall thickness is at 33～35 millimeters, maximum operation (service) temperature is at 1195 ℃, during use magnesium ore is put into jar, jar is presented in the High Temperature Furnaces Heating Apparatus, vacuum is taken out pressure in jar.In use, because the tank body outside is subjected to high bake, inside will be subjected to vacuum pump to take out pressure, inclement condition, and tank body is yielding, thereby causes gas leakage to be scrapped, and is generally work-ing life 3 months, and production cost is bigger.At this situation, relevant research department attempts to improve the temperature resistance withstand voltage properties from the material that changes tank body, thereby prolong the work-ing life of tank body, Chinese patent application number is 95116406, its name is called " the reduction jar and the production method thereof that are used for magnesium metal smelting " and promptly belongs to this type of invention, but for various reasons, this invention does not obtain implementing.
The problem that the purpose of this utility model is poor at existing tank body temperature resistance withstand voltage properties in the above-mentioned prior art just, work-ing life is short and a kind of novel reduction jar developed.This reduction jar employing bilayer structure, the temperature resistance withstand voltage properties greatly improves, and be enhanced about more than once its work-ing life than before.
The purpose of this utility model realizes by following measure: be applicable to that originally the reduction jar that magnesium is smelted comprises tank body, and reduction jar be a bilayer structure, suit one is made by silicon nitride or carbofrax material in outer tank body, its shape and the corresponding to lining jar of outer tank body.
In the utility model, the wall thickness of outer tank body is 10～20 millimeters, and the wall thickness of lining jar is 10～35 millimeters; Gap between outer tank body and the lining jar is greater than zero.
The advantage that the utility model is compared with prior art possessed is: owing to adopted bilayer structure, outer tank body is still selected original nichrome material for use, the internal layer tank body then selects for use good heat conductivity, little, the against corrosion wear resistance of thermal expansivity is good, compressive strength is high silicon nitride or carbofrax material to make, its product is high temperature resistant to reach 1790 ℃, is 1000kg/cm 1550 ℃ of compressive strengths
2, in the time of 1200 ℃, compressive strength is bigger, and it is indeformable that its internal layer lining jar also can support outer tank body, therefore is out of shape gas leak phenomenon and is curbed, and guaranteed the work-ing life of product.This reduction jar structure is reasonable in design, and is safe and reliable, and be enhanced about more than once work-ing life than before.
Accompanying drawing is that the utility model structure master cuts open figure.
The utility model is done below in conjunction with accompanying drawing and is described in further detail: as shown in the figure: be applicable to that originally the reduction jar that magnesium is smelted is a bilayer structure, suit one is made by silicon nitride or carbofrax material in outer tank body (1), the corresponding to lining of its shape and outer tank body jar (2), the wall thickness of outer tank body is 15 millimeters, and the wall thickness of lining jar is 20 millimeters; Gap between outer tank body (1) and the lining jar (2) is to be advisable movingly.
Claims (4)
1, a kind of reduction jar that is applicable to that magnesium is smelted, it comprises tank body, it is characterized in that: this reduction jar is bilayer structure, suit one is made by silicon nitride or carbofrax material in outer tank body (1), its shape and the corresponding to lining jar of outer tank body (2).
2, the reduction jar that is applicable to that magnesium is smelted according to claim 1, it is characterized in that: the wall thickness of outer tank body (1) is 10～20 millimeters.
