Description
Technical field
The new electric-heating heat treatment technical field that belongs to of this practicality is specifically related to a kind of box high temperature furnace.
Background technology
Box high temperature furnace is one of capital equipment that sample or workpiece is heated (like heat treatment, ashing, fusion, destructive distillation, burning etc.); Common chamber type electric resistance furnace adopts alumina silicate, alumina fibre to make burner hearth or furnace lining, and heating is arranged in the sidewall of burner hearth.High temperature furnace for about 1600 ℃; Generally select polycrystalline mullite fibre material burner hearth for use; Because of refractory material near resistance to extreme temperature, refractory material is partly understood the fusion porcelainization near electrical heating elements in the use, and then sticks on the electrical heating elements; In cooling procedure, produce stress and damage, influence high temperature furnace service life.
The high temperature furnace fire resistant material all adopts extraordinary high-temperature refractory (like zirconia material etc.); Its resistance to extreme temperature can improve greatly; The fine disadvantage that overcomes common high-temperature refractory fusion porcelainization of ability; But extraordinary high-temperature refractory is complicated because of manufacturing technology, and prices are rather stiff for it, and the high temperature furnace operating cost made from superrefractory is very high.
Summary of the invention
The purpose of the utility model is the higher electric heating equipment of a kind of cost performance of development and Design, is specially a kind of box high temperature furnace.
The utility model is made up of housing, heat-insulation layer, burner hearth and Si-Mo rod; Burner hearth comprises furnace roof, furnace bottom, furnace wall, back and furnace wall, both sides; It is characterized in that U-shaped Si-Mo rod furnace wall behind burner hearth wing furnace wall and burner hearth layout that takes the shape of the letter U; Burner hearth bottom, furnace wall, both sides, furnace wall, back are built by laying bricks or stones by common highiy refractory brick, and the burner hearth furnace roof is built by laying bricks or stones by common highiy refractory brick and extraordinary highiy refractory brick, extraordinary highiy refractory brick assembling U-shaped Si-Mo rod.
The material of said common highiy refractory brick is a polycrystalline mullite fibre.
The material of said extraordinary level highiy refractory brick is a Zirconium oxide fibre.
The utility model beneficial effect is: simple in structure, design science is reasonable, is suitable for 1600～1650 ℃, and cost performance is very high.

Fig. 2 is the burner hearth perspective view.
Among the figure, 10-housing, 20-heat-insulation layer, 30-burner hearth, the common highiy refractory brick of 31-, the extraordinary highiy refractory brick of 32-, 40-Si-Mo rod.
The specific embodiment
Explain as follows in conjunction with Fig. 1 and Fig. 2 the utility model specific embodiment:
A kind of box high temperature furnace; Constitute by housing 10, heat-insulation layer 20, burner hearth 30 and Si-Mo rod 40; Burner hearth 30 comprises furnace roof, furnace bottom, furnace wall, back and furnace wall, both sides, it is characterized in that U-shaped Si-Mo rod 40 layouts that take the shape of the letter U along furnace wall, burner hearth 30 both sides and furnace wall, back, and burner hearth 30 bottoms, furnace wall, both sides, afterwards the furnace wall is built by laying bricks or stones by common highiy refractory brick 31; Burner hearth 30 furnace roofs are built by laying bricks or stones with extraordinary highiy refractory brick 32 by common highiy refractory brick 31, extraordinary highiy refractory brick 32 assembling U-shaped Si-Mo rods 40.
The material of said common highiy refractory brick 31 is polycrystalline mullite fibres.
The material of said extraordinary highiy refractory brick 32 is Zirconium oxide fibres.
The utility model is simple in structure, and design science is reasonable, is suitable for 1600～1650 ℃, and cost performance is very high.
