Problems solved by technology

[0003] In order to prolong the service life of the grate plate, it is usually used to thicken the wear-resistant alloy to improve its performance. However, while the wear resistance is increased, the wear-resistant alloy layer will be caused by the impact wear of the sinter The phenomenon of falling off and falling blocks shortens the service life of the grate plate

Embodiment 1

[0028] like Figure 1-Figure 3 The shown grate plate of the present invention includes the following structure: the fitting position of the grate plate body 1 is provided with two grooves; the transverse middle of the groove is provided with a vertical rib that matches the shape of the groove. 9; In the two areas divided by the vertical bars 9, separate rib plates 5 are set up longitudinally staggered; The height of the upper horizontal plate should be lower than the height of the grate plate body 1 , and the wear-resistant alloy 3 is filled in the grid area formed by the vertical rib 9 , the spacer rib plate 5 and the horizontal plate 2 .

[0029] The above-mentioned upper end surface of the grate plate body 1 is also surfacing with a wear-resistant and high-temperature resistant alloy layer 7 so as to be closely connected with the grate plate body 1 .

[0030] A wear-resistant and high-temperature-resistant alloy layer 4 is also surfacing on the side surface of the upper pa...

Abstract

The invention relates to crushing equipment arranged in a sintering machine in an iron and steel plant, and particularly relates to a wear-resisting and high temperature-resisting grate for a crusher. The grate comprises structures as follows: a groove is formed in an adaptive position of a grate body; vertical ribs matched with the groove in shape are arranged in the horizontal middle part of the groove; partition ribbed plates are respectively longitudinally arranged in a staggered manner inside two areas divided by the vertical ribs; each area surrounded by the vertical ribs and the partition ribbed plates is at least provided with a layer of horizontal plates in a manner of being vertical to the partition ribbed plates; and a grid area formed by the vertical ribs, the partition ribbed plates and the horizontal plates is filled with wear-resisting alloy. The grate disclosed by the invention is a grate for the crusher, which is convenient to maintain, low in production cost and long in service life and also has good high temperature resistance and wear resistance.

Description

technical field [0001] The invention relates to an equipment for crushing in a sintering machine of an iron and steel plant, in particular to a wear-resistant and high-temperature-resistant grate plate for a crusher. Background technique [0002] In the sintering machine equipment, the grate plate is placed at the bottom, the single-tooth roller star wheel is inserted into the grate plate, and the 700-800° hot sinter is crushed by the rotation of the single-tooth roller crusher star wheel and the grate plate. The area where the grate plate and the star wheel cooperate is the most severely impacted and worn, with heavy workload, high temperature and harsh working conditions. With the increase of crushing workload, the service life of the grate plate is significantly shortened, which affects the normal operation of the crusher, so it is particularly important to improve its service life. [0003] In order to prolong the service life of the grate plate, it is usually used to t...
