Embodiment 1

[0038] Embodiment 1, a method for manufacturing a silicon carbide grinding bucket in a grinding device, comprising the following steps:

[0039] 1), ingredients

[0040] Add silicon carbide to the reaction catalyst and additives, add water while stirring, and stir evenly. The weight ratio of the various components is:

[0041] 65 parts of silicon carbide, 5 parts of reaction catalyst, 10 parts of additive; appropriate amount of water;

[0042] Silicon carbide, reaction catalysts and additives are compounded in granular powder, the size of the particles is between 2 microns and 150 microns, the main component of the reaction catalyst is carbon powder, and the main components of the additives are polyvinyl alcohol and dipropylene glycol Alcohol, according to the amount of water added, the material after batching can be made into slurry or powder.

[0043] 2. Blank forming

[0044] Use the mold to produce the blank of the silicon carbide grinding bucket of the corresponding s...

Embodiment 2

[0056]Embodiment 2, in step 1 of above-mentioned embodiment 1, the proportioning of described various component weights can also be: silicon carbide 75 parts, reaction catalyst 15 parts, additive 30 parts; 1 is the same.

Embodiment 3

[0057] Example 3, in the step 1 of the above-mentioned example 1, the weight ratio of the various components is: 70 parts of silicon carbide, 10 parts of reaction catalyst, 20 parts of additives; appropriate amount of water. Other processing steps are identical with embodiment 1.

[0058] In the above-mentioned Examples 1-3, silicon carbide reacts with reaction catalysts, additives and silicon alloys at high temperatures to produce composite silicon carbide. The main characteristics of this material are high temperature resistance, wear resistance, and corrosion resistance. The physical properties of the material are stable, and the sintered grinding barrel is mainly composed of this material. The invention adopts the above scheme, and the silicon carbide grinding barrel produced not only has excellent wear resistance performance, but also has high hardness, high specification and dimension precision, and long service life.

[0059] The performance comparison of silicon carbi...

Abstract

The invention discloses a method for manufacturing a silicon carbide grinding barrel in a grinding device, comprising the following steps: 1) batching, adding silicon carbide into a reaction catalyst and an additive, adding water while stirring, and stirring evenly to form a slurry or powdery material; 2) ) Biscuit molding, the slurry or powdery material is used in the mold to produce the biscuit of the silicon carbide grinding barrel of the corresponding size through grouting molding or isostatic pressing; 3) Drying, repairing and sintering of the biscuit: The green body is dried, and the dried green body is repaired. After the repair, the green body is put into a vacuum furnace and silicon alloy is added for sintering; 4) Finishing of the sintered product: the sintered silicon carbide grinding barrel is installed in the CNC machining Finishing on the center. The silicon carbide grinding bucket made by the invention not only has excellent wear resistance performance, but also has high hardness, high specification and dimension precision and long service life.

Description

technical field [0001] The invention relates to a method for manufacturing a silicon carbide grinding barrel in grinding equipment, and belongs to the technical field of silicon carbide products. Background technique [0002] The grinding machine is suitable for deburring, derusting, rounding and bright polishing of various parts of metal, non-ferrous metal and non-metal products. It is especially suitable for surface finishing of deformable workpieces. The parts after finishing by this type of grinding machine not only maintain the original shape and position accuracy, but also improve the surface roughness of the parts by 1-2 grades. [0003] The grinding cylinder is an important component of the grinding machine. The grinding cylinders that appear on the market are usually made of stainless steel surface nitriding, but the service life of this grinding cylinder is short, and various metal ions will pollute the material, powder If the body color turns gray or black, the p...
