A groove graphite boat, which comprises a plurality of with the relative groove surface and bottom supporting protrusions W-shaped bidirectional skewed, bottom surface, face, side, side and the upper end relative to the mouth and two corresponding slot surface were designed with at least a vent groove, bottom bulge supports and the relative groove surface intersection, respectively, and the design of an angular slot protective. Bottom surface at either of two adjacent W-shaped bidirectional skewed slots forming the protrusion of the lower design parallel to W-shaped bidirectional skewed slots, section shape is approximate of the V-shaped grooves. The utility model makes the hard alloy strip product uniformly in the process of hydrogen and vacuum sintering, so as to avoid the distortion of the product, and the product has large loading capacity and less material consumption.
Graphite boat structure
A groove graphite boat including several with the relative groove surface and the bottom supporting protrusions W-shaped bidirectional skewed, bottom surface, face, side, side and the upper end relative check mouth, its characteristics is relative to the groove surface and are designed to less a vent groove, and groove surface of the bottom supporting protrusions and the relative intersection, respectively, and the design of a corner protecting groove.
Thin graphite boat
Thin graphite boat, like a dry load bar groove W boat body, a cushion block and with a certain taper pin side arrangement includes a boat body, both ends of the parallel loading bar groove W are respectively provided with grooves, pad bottom bosses and grooves with the positioning pin positioning hole and middle block through the middle of the lower convex groove; the bottom of the table W loading bar groove bottom surface of the bottom to the boat body distance, top to the boat body distance, block top surface to the upper convex table distance, cushion block and the boat body with the top surface to the bottom of boat table the distance were 2.0-8 mm, 3-16 mm, 3.8-12 mm, 6.8-28 mm; groove spacing groove loaded bar groove W bottom width, height, angle of groove were 2.6-12.4 mm, 0.2-3 mm, 1.2-9 mm, 50 degrees -60 degrees; the utility model can improve the sintering furnace, a single furnace production, extend the boat real The service life of the boat is also saved.
