However, the assembly between the grate and the sintering trolley is not very convenient, resulting in assembly difficulties. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a high-chromium cast iron grate bar.

[0006] The utility model is implemented by the following technical scheme: a high-chromium cast iron grate bar is provided with a grate bar plate, an assembly component is arranged on the grate bar plate, the assembly component is an assembly groove, a grate bar is placed in the assembly groove, a locking component is arranged between the grate bar and the assembly groove, the locking component is a locking hole, the locking holes are distributed on both sides of the assembly groove, a locking rod is horizontally inserted into the locking hole, a connecting component is arranged at the bottom of the grate bar plate, the connecting component is a connecting plate, a connecting threaded hole is arranged on the connecting plate, and a threaded rod is assembled in the connecting threaded hole.

[0007] A bottom receiving plate is arranged between the grate plate and the connecting component, and a plurality of receiving grooves are arranged on the bottom receiving plate, and the receiving grooves are long strip structures.

[0008] The connecting plate is provided with a shelf, the shelf is provided with a shelf space, and the bottom receiving plate is slid into the shelf space.

[0009] The upper part of the grate plate is provided with a side baffle plate, and the side baffle plate is provided with side holes, and the side holes are side round holes.

[0010] Compared with the prior art, the utility model can utilize the assembly line between the grate bars and the grate plates to form a complete platform for placing sintered ore when in use. A connecting plate for assembly with the sintering trolley is provided at the bottom of the grate plate, and a slot is provided on the sintering trolley. By inserting the connecting plate into the slot, the grate plate and the sintering trolley can be well assembled, and the assembly efficiency is further improved, meeting the assembly needs between the sintering trolley and the grate plates.
