Abstract
The utility model provides a grate plate for a sintering machine, which comprises a cast body (6), a cooling water passage (1) arranged inside the cast body (6), reinforcement plates (7) arranged on the cast body (6) to form grids (4), and wear-resistant layers (8) fixed in the grids (4) by build-up welding, wherein the cast body (6) has a bottom part (5) and a top part (3), the top part (3) is raised, and sloped transitional surfaces (2) are formed at the two ends of the cast body (6). With the improved design on the existing products, the number of the build-up welded wear-resistant alloy grids is increased by increasing the number of the reinforcement plates on the cast body, and the key parts are treated with high-chrome alloys by build-up welding, so that the spatial wear resistance is uniformly distributed, the crushing capacity is improved, the wear resistance is enhanced, and the service life is increased. The grate plate for the sintering machine has the characteristics of reasonable structure, long service life and low manufacturing cost. The price of the grate plate is only 20% of the existing similar products; and the grate plate has good market prospects, and can be widely applied to different types of sintering equipment.
Description
Technical field: the utility model relates to a kind of sintering machine grate plate, is mainly used in the fragmentation of the tabular solid-state ore behind the sintering in the iron ore smelting process.
Background technology: the fragmentation of the tabular solid-state ore in the iron ore smelting process behind the sintering, because of its operating mode complexity, very high to sintering machine grate plate technique conditional request.The used sintering machine grate plate of China substantially all is from external import at present, but because its structural reason, this product is its groundwork face top center position and sidepiece rapid wear in use, thereby the inhomogeneous grate slab integral that causes of working face abrasion resistance is scrapped the whole result of use of influence in early days.Therefore, exist the shortcoming that the replacement cycle is short, use cost is high.
Summary of the invention: at above-mentioned the deficiencies in the prior art, it is a kind of more wear-resisting that the utility model provides, the sintering machine grate plate that use cost is lower.
For achieving the above object, the technical solution adopted in the utility model is: a kind of sintering machine grate plate, comprise foundry goods body (6), be provided with cooling water channel (1) in the foundry goods body (6), described body (6) is provided with to be strengthened gusset (7) and is shaped on space (4), and built-up welding has wearing layer (8) in space (4).Body (6) also is provided with bottom (5) and top (3), top (3) projection, and slope transition face (2) is made at two ends.
The utility model is owing to carried out Transform Type design to existing product, increase the gusset quantity of body, its build-up wear-resistant alloy space is increased, adopted novel high chromium alloy material that keypoint part is carried out built-up welding, its equal portion of space abrasion resistance, breaking capacity is strong, anti-wear performance good, life cycle is long.Characteristics with rational in infrastructure, long service life, low cost of manufacture.This product has good market prospects, can be widely used on all types of agglomerating plants.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the B-B profile of Fig. 1.
The specific embodiment:
As depicted in figs. 1 and 2: a kind of sintering machine grate plate, comprise foundry goods body 6, be provided with cooling water channel 1 in the foundry goods body 6, described body 6 is provided with to be strengthened gusset 7 and is shaped on space 4, and built-up welding has wearing layer 8 in space 4.Body 6 also is provided with bottom 5 and top 3, top 3 projectioies, and slope transition face 2 is made at two ends.Described top 3 has wearing layer 9.Body 6 is provided with horizontal gusset 10, and laterally the gusset number is 16.
For improving its groundwork face abrasion resistance, increase top wearing layer thickness, it increases size range and is controlled at 30-35mm.
Claims (2)
1. sintering machine grate plate, comprise foundry goods body (6), be provided with cooling water channel (1) in the foundry goods body (6), described body (6) is provided with to be strengthened gusset (7) and is shaped on space (4), built-up welding has wearing layer (8) in space (4), and body (6) also is provided with bottom (5) and top (3), top (3) projection, and slope transition face (2) is made at two ends, and body (6) is provided with horizontal gusset (10).
