Abstract
The invention discloses a single-roll grid plate and a manufacture method of the single-roll grid plate. The single-roll grid plate manufactured by using the manufacture method comprises a grid plate wedge-shaped main body and an alloy block, wherein the grid plate wedge-shaped main body is connected with the alloy block through a bolt. A production process of the single-roll grid plate is realized by changing a production process of the conventional heat-resistant and wear-resistant alloy pouring into a process of casting a heat-resistant and wear-resistant regulating block, pouring and forming, and finally directly clamping on the grid plate wedge-shaped main body. In order to prevent the whole alloy block from dropping, the alloy block is fixed by using a bolt, therefore, the heat-resistant and wear-resistant alloy 1 and the grid plate main body 2 can be tightly combined together, the wear-resistant strength of the whole grid plate is enhanced, the service life of the grid plate is maximally prolonged, the waste of a heat-resistant and wear-resistant alloy steel material is avoided, and the manufacture cost of the grid plate is saved.
Description
Technical field
The present invention relates generally to steel industry agglomerating plant equipment field, is specifically related to a kind of preparation method of super wear-resisting low-cost single roller grate plate.
Background technology
Single roller grate plate is the important component part of sintering machine single roll crusher.Because its broken thing to be processed is up to the sintering deposit about 800 ° of C, it bears bigger thermic load and shock loading simultaneously, and stressed complexity is inhomogeneous, causes grate plate wearing and tearing aggravation.When serious single roller grate plate therefrom between fracture, restricting sintering machine production and carrying out smoothly.
The casting pig that tradition grate plate parent adopts, its tensile strength is 150MPa, good casting property, technology is simple, certain anti-corrosion resistance and wearability are arranged, but toughness and processing characteristics is poor.After the grate plate parent may wear to a certain degree, is subjected to greater impact load, the possibility of fracture is arranged.
The tradition grate plate make to adopt the manufacture craft of antiwear heat resisting alloy cast, this complex manufacturing technology and cost height, and all there are certain defective in traditional fabrication grate plate parent material and frame mode, have drawbacks such as service life is too short.Not only increase the maintenance cost of agglomerating plant, and strengthened working strength of workers.
Summary of the invention
Target of the present invention is to solve single roll crusher uses grate plate service life too short, cost and crosses high technical problem, and a kind of super wear-resisting low-cost single roller grate plate is provided.
The method for preparing single roller grate plate comprises grate plate wedge shape parent and the alloy block that preparation has groove shape structure, and alloy block is fastened in the groove shape structure, and connects grate plate wedge shape parent and alloy block by bolt.
Super wear-resisting low-cost single roller grate plate provided by the invention comprises grate plate wedge shape parent and alloy block, and wherein grate plate wedge shape parent is connected by bolt with alloy block, and the grate plate parent has groove shape structure, and alloy block is sticked in the groove shape structure.
Parent preferably uses metal Q235 steel billet, its metal solder performance, strong, the impact resistance of toughness, and better than traditional grate plate HT150 casting pig performance, economy is strong.
The manufacturing process of grate plate wedge shape parent is: according to the easy abrading section of grate plate situation, and cutting fluting on the Q235 steel billet.Parent is whole to remove traditional cooling water pipe for solid, avoids because grate plate causes when may wear to cooling water pipe leaks, and weakens the appearance of grate plate integral intensity phenomenon.
In the middle of grate plate parent 2 flutings, welding perforate steel plate 4 is such as the perforate steel plate of the thick 20CM of welding, to be used as the bolting antifriction alloy.This processing technology avoids that two kinds of different metals are cast in together in traditional grate plate manufacture craft, and cast back alloy and metallic framework separate the appearance with obscission easily.
Preferably, the alloy block material is a heat-resistance abrasion-resistance alloy.
Preferably, the production technology of alloy block changes casting heat-resistant abrasion-resistant stee monoblock into by the production technology of traditional heat-resistance abrasion-resistance alloy cast, directly is stuck in behind the moulding by casting on the grate plate wedge shape parent 2.
Preferably, the casting heat-resistant antifriction alloy of employing is a high-chromium-nickel steel, contains Cr 〉=18%, contains Ni 〉=8%, and elementary organization is an austenite, and a little ferrite is arranged.Its corrosion resistance is also stronger, and this casting heat-resistant abrasion-resistant stee carbide at high temperature has very strong stability, can be applicable to the working condition below 1093 ℃.Easily produce the σ phase at 649-870 ℃, hardness can reach HRC50-62.Be more than 3-5 times of common rich chromium cast iron 60CR.
For preventing that the monoblock alloy from coming off, use the M20 bolting, heat-resistance abrasion-resistance alloy 1 and grate plate parent 2 can be combined closely, improve its rub proofness.
Preferably, after grate plate antiwear heat resisting alloy 1 and grate plate parent 2 usefulness bolts 3 were fixed, for improving the constant intensity of its abrasive resistance and wear-resisting alloy block, high chromium welding rod can be welded in the position of the easy wearing and tearing of grate plate.
The present invention can effectively strengthen the scuff resistance of grate plate integral body, avoids the waste of heat-resistance abrasion-resistance alloy steel material the service time of improving grate plate to greatest extent, saves the cost of manufacture of grate plate.
