Abstract
The invention discloses a high-temperature resistant nonmetallic vertical reduction tank, which comprises a water jacket, a vertical tank body and a lower tank opening connecting pipe sequentially butted and communicated from top to bottom, wherein the vertical tank body is made of refractory material; rigid sealing sleeves are sleeved at the joints between the tank body and the water jacket and between the tank body and the lower tank opening connecting pipe respectively; and annular sealing rings are arranged in the rigid sealing sleeves on the upper and lower sides of each joint. The reduction tank is simple in structure and convenient to use; and each component is vertically arranged, so the reduction tank is suitable for a vertical reduction furnace. Because the vertical tank body is made of the refractory material, the reduction tank has good corrosion resistance and oxidation resistance and excellent heat conduction capability and high-temperature strength; and the service life of the reduction tank can reach over 6 months and is prolonged by about 3 times compared with the conventional reduction tank, and the production cost is effectively reduced.
Description
Technical field
The present invention relates to the Metal smelting technical field, especially a kind of reduction jar.
Background technology
The reduction jar is the core component of smelting magnesium, calcium reduction stove, because of it (work under 1～5Pa) the condition, so material must have good anti-oxidant, hot corrosion resistance, have the stability of higher high temperature strength and comprehensive mechanical performance and processing characteristics and this material high temperature microstructure to want good under 1200 ℃ of temperature at high temperature (1200 ℃), high vacuum.The present material that uses following several high temperature steel do reduction jars both at home and abroad is as ZG35Cr24Ni7SiN (3Cr24Ni7N), HK-40 (25Cr-20Ni), HI (28Cr16Ni) etc.Existing reduction jar is horizontally disposed reduction jar, comprises water jacket, tank body, and wherein tank body is the heating resisting metal material.The shortcoming of existing reduction jar is to use the life-span short, involves great expense, and is not suitable for vertical reduction furnace.In actually operating, reduction cycle shortens for improving output in factory, and the fire box temperature of magnesium, calcium reduction stove remains on about 1250 ℃ for a long time, and therefore, material and processing quality are good again, and the work-ing life of reduction jar is still shorter, has only about 60 days.Need add the high alloying elements of price such as chromium, nickel during the casting of reduction jar.According to statistics, 0.2 in ton magnesium consumption reduction jar, 30% of xanthenes magnesium production cost.
Summary of the invention
The object of the present invention is to provide a kind of lower vertical high temperature resistant nonmetal vertical reduction of vertical reduction furnace and longer service life, production cost jar of being applicable to.
For achieving the above object, vertical tank body, following jar of mouth pipe connecting that high temperature resistant nonmetal vertical reduction jar of the present invention comprises the water jacket that is docked and connected successively from top to bottom, made by refractory materials, seam crossing between tank body and water jacket, tank body and following jar mouthful of pipe connecting all is arranged with the positiver sealing sleeve, and each seam is all pressed in the positiver sealing sleeve of both sides up and down and is provided with grommet type seals.
All press in the positiver sealing sleeve of both sides about described each seam and be provided with double-deck grommet type seals.
Described vertical tank body is made by carbon containing refractory high temperature sintering after extrusion molding.
The present invention has following advantage:
1. the present invention is simple in structure, and is easy to use, and each parts all vertically is provided with, and is applicable to vertical reduction furnace.Because vertical tank body is made by refractory materials, therefore have good anticorrosive, antioxidant property, good thermal conduction capability and hot strength are arranged; And its work-ing life be more than 6 months, compare existing reduction and jar prolonged about 3 times work-ing life, thereby effectively reduced production cost.
2. all press in the positiver sealing sleeve of both sides about described each seam and be provided with double-deck grommet type seals, can either effectively guarantee sealing effectiveness, exceed the use sealing material again.
3. vertical tank body is made by carbon containing refractory high temperature sintering after extrusion molding, can guarantee that vertical tank body has good anticorrosive, antioxidant property and good thermal conduction capability, hot strength, is convenient to make simultaneously.
Description of drawings
Fig. 1 is a sectional structure synoptic diagram of the present invention under the installment state.
Embodiment
As shown in Figure 1, high temperature resistant nonmetal vertical reduction jar of the present invention comprises water jacket 1, vertical tank body 2 and the following jar mouthful of pipe connecting 3 that is docked and connected successively from top to bottom, seam 4 places between tank body 2 and water jacket 1, tank body 2 and following jar mouthful of pipe connecting 3 all are arranged with metal rigidity seal sleeve 5, in the positiver sealing sleeve 5 of each seam both sides 4 about all pressure be provided with double-deck grommet type seals 6.Wherein, make after extrusion molding by high temperature sintering by carbon containing refractory (as silicon carbide or graphite clay) for described vertical tank body 2, and grommet type seals 6 is a heat-resistant rubber seal ring.
As shown in Figure 1, the length of tank body 2 is slightly long than the body of heater 7 of vertical reduction furnace, first is that tank body is located in the body of heater 7 of reduction furnace during installation, the top (bottom) that makes the top (bottom) of vertical tank body 2 stretch out body of heater 7, the middle portion of vertical tank body 2 be the heated portion during as work in the burner hearth that body of heater 7 is surrounded; The secondth, in the top and the bottom of vertical tank body 2 water jacket 1 and following jar mouthful of pipe connecting 3 are installed respectively; The 3rd is at seam sheathed heat-resistant rubber seal ring 6 in both sides about in the of 4, be enclosed within the outer rim of sealing-ring 6 then with metal rigidity seal sleeve 5, thereby rely on metal rigidity seal sleeve 5 to guarantee can not misplace between tank body 2 and water jacket 1, tank body 2 and following jar mouthful of pipe connecting 3, rely on the squeeze crush seal circle 6 between metal rigidity seal sleeve 5 and water jacket 1, vertical tank body 2, the following jar mouthful of pipe connecting 3 simultaneously, thereby guarantee seam 4 place's good seals.
Claims (3)
1. high temperature resistant nonmetal vertical reduction jar, it is characterized in that: vertical tank body and following jar mouthful of pipe connecting of comprising the water jacket that is docked and connected successively from top to bottom, making by refractory materials, seam crossing between tank body and water jacket, tank body and following jar mouthful of pipe connecting all is arranged with the positiver sealing sleeve, and each seam is all pressed in the positiver sealing sleeve of both sides up and down and is provided with grommet type seals.
2. high temperature resistant nonmetal vertical reduction jar according to claim 1 is characterized in that: all press in the positiver sealing sleeve of both sides about described each seam to be provided with double-deck grommet type seals.
3. high temperature resistant nonmetal vertical reduction jar according to claim 1 and 2, it is characterized in that: described vertical tank body is made by carbon containing refractory high temperature sintering after extrusion molding.
