Abstract
The utility model relates to a single roll crusher grid plate. Wear resistance layers produced by the way of build-up welding are arranged on the external side of the grid plate. The seriously wear-out upper part of the grid plate is in a composite structure composed of parent materials and a plurality of wear resistance layers produced by the way of build-up welding. By adopting the composite structure of the wear resistance layers, the utility model strengthens the wear-resistant ability and has the advantages of easy manufacture, low cost, strong wear resistance and long service life. Normal work can be ensured under the condition of high temperature of 800 degrees C.
Description
Technical field
The utility model relates to a kind of single roll crusher annex, the single roll crusher grate plate that the hot crushing system of specifically a kind of sintered production line uses.
Background technology
The mineral aggregate sintering is that an indispensable procedure is produced in ironmaking, and the hot crushing system of sintered production line is made up of single roller and grate plate, and its function is sintering mineral aggregate together to be broken into satisfy the size that iron-smelting process requires under hot state.The single roll crusher grate plate is the key working part of the hot crushing system of sintered production line, and the military service operating mode is abominable, and the work temperature is directly connected to the integral device utilization rate or the repair rate of sintered production line its service life 600-800 ℃ of scope.Grate plate is mainly born the abrasive wear of high temperature mineral aggregate in working order down, and near under the situation of grate plate, grate plate is born bigger impact sometimes at the tail discharging point, and this is a kind of ten minutes bad working environment.The grate plate that domestic each big steel enterprise uses adopts monoblock cast or forging mostly.The whole grate plate of making must be considered combination properties such as the intensity of material, toughness, wearability simultaneously, can't pursue the high-wearing feature index.Therefore, the grate plate working life that domestic each big steel enterprise uses is generally on the low side, and single head seriously restricted the production efficiency of sintering line service life within three months usually.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of single roll crusher grate plate of many wearing layers composite construction of simple in structure, easy to make, with low cost, high life is provided.
The scheme that the utility model solves the problems of the technologies described above employing is: a kind of single roll crusher grate plate is characterized in that: the grate plate outside is provided with the wearing layer that overlaying method is made, and top is mother metal and the composite construction that constitutes with a plurality of wearing layers that overlaying method is made.
The utility model single roll crusher grate plate adopts many wearing layers composite construction, and is against existing technologies, easy to make, cost is low, wearability is high, high life, can guarantee operate as normal under 800 ℃ of hot conditions.Many wearing layers composite construction has been strengthened abrasive resistance greatly.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1.
1. install draw-in groove, 2. mother metal, 3. wearing layer among the figure.
The specific embodiment
From Fig. 1, Fig. 2 as can be seen, a kind of single roll crusher grate plate, it is provided with installs draw-in groove 1, is installed on the single roll crusher by draw-in groove 1 is installed.The matrix of grate plate is 45# cast steel or forged steel, and the grate plate outside is provided with the wearing layer 3 that overlaying method is made, and the position of top serious wear is mother metal 2 and the composite construction that constitutes with the wearing layer 3 that overlaying method is made.As shown in Figure 2, overlaying method is made and is provided with five layers of wearing layer 3 on it.
The utility model is done under the prerequisite of wearing layer at selected high-performance high temperature resistance lost material, and ingenious design wearing layer structure makes abrasive resistance perform to the limit.The grate plate of multilayer structure is equivalent to have a plurality of wearing faces, and each wear-resistant surface work one-period is looked life requirements and arranged the wearing layer number of plies, meets the requirements of service life.Under the broken operating mode of sintering mineral aggregate heat, the utility model not only is much higher than the grate plate that prior art is made service life, and can be as requested design service life in advance.The utility model can be used for the sintered production line single roll crusher grate plate manufacturing of all size.Its advantage is: 1, easily manufactured, cost is low.The wear-resisting reinforcement of whole grate plate is finished by bead-welding technology, and is easily manufactured; Precious metal only uses on the surface of taking up wear, and a large amount of matrix materials then is 45# cast steel or forged steel, so the noble metal alloy consumption is few, and is with low cost.2, high life, to bear the high temperature wear ability strong.The grate plate that the utility model is made because matrix is 45# cast steel or forged steel, has good intensity, toughness and plasticity, and the course of work is resisted the task of external force and born by it; Wearing layer is only finished single task role---and wear-resistant, therefore can bring into play wearing layer high temperature hardness height, strong, the strong characteristic of high temperature resistance wearing and tearing ability of stability as far as possible, thereby reach the purpose that improves service life.
