Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the utility model, are intended for purposes of illustration only and are not intended to limit the scope of the utility model. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 3, in an embodiment of the present invention, a hard alloy T-bar sintering boat includes a boat body 1, wherein a plurality of V-shaped grooves 2 are uniformly arranged on an end surface of the boat body 1;

the two inclined planes in each V-shaped groove 2 are provided with a plurality of step surfaces 201 which are uniformly distributed along the length direction of the V-shaped groove 2; t-shaped rod products 3 are arranged at the corresponding positions of every two opposite step surfaces 201 on the V-shaped groove 2; boat body 1 has a plurality of V type groove 2, and every V type groove 2 has a plurality of ladder faces 201, uses this boat sintered product to be equipped with the stove volume and promotes by a wide margin, adopts V type ladder boat sintering, and many products can be put to every cell type.
