Slurry pump tool selection ceramic tool is better

Domestic companies engaged in the production of slurry pumps and their parts are faced with the problem of selecting a machining tool, which is determined by the basic performance of the product. The main feature of the slurry pump is that the transport fluid path is highly resistant. Grinding or corrosion resistance, it is suitable for conveying abrasive or corrosive slurry. Its products are widely used in mining, metallurgy, petroleum, coal, transportation, electric power, building materials and municipal engineering projects for mining, dredging and transportation. Strong abrasion, high concentration slurry transportation of tail, concentrate sand, ash, coal slurry, iron powder, etc.

At present, the wear-resistant parts of most slurry pumps in China are made of high-chromium cast iron. The hardness of high-chromium cast iron can reach up to HRC65. It is one of the best wear-resistant materials at present, and the alloy has a large amount of use and complicated production process. Since the 1980s, it has been applied in China in the 1990s. Its machining generally uses carbide tools. The machining process is complicated, the cost is high and the efficiency is low. Its difficult machining has been plagued by many machining manufacturers.

Ceramic tool is a new type of material tool in modern metal cutting. It is characterized by high hardness, high strength, high red hardness, high wear resistance, excellent chemical stability and low friction coefficient. It can process not only some ordinary blades. Superhard materials that cannot be processed, and can improve production efficiency.

The use of ceramic knives in many slurry pump manufacturers proves that it can solve the mechanical processing difficulties of high chromium cast iron, which not only can effectively reduce production costs, but also greatly improve production efficiency. The wear parts of the slurry pump generally include sheath (worm wheel), guard plate (front guard plate, rear guard plate), impeller, auxiliary impeller, decompression cover, etc. The following is a detailed process analysis of the processing of some wear parts. :

First, using ordinary tool processing
Processing technology: casting - annealing - cutting - quenching
Brief analysis: The process has undergone two heat treatments, with long cycle and high cost. For the protective plates and sheaths with matching requirements, it can be directly processed without annealing, and only low-speed cutting can be used, and the production efficiency is too low.

Second, the use of ceramic tool processing
Processing technology: casting - cutting
Brief analysis: 1. Reduce the two heat treatment processes, greatly reduce energy costs, and have a short production cycle. 2, using ceramic knives, can directly carry out rough and fine processing without annealing, not only reduce two heat treatment processes, save a lot of energy consumption costs, and can be processed at a higher speed, greatly improve production efficiency, can meet with less equipment The need for production or the same equipment meets the needs of higher production.

At present, there are many manufacturers of ceramic knives in China. There are many kinds of tool materials, and the performance is quite different. It is very important to solve the cutting process of high-chromium cast iron. It is extremely important for the correct selection of ceramic knives. If it is not properly selected, it will not only affect your promotion. The use of ceramic knives affects your production and can cause you to lose confidence in ceramic knives, which has always been processed by ordinary tools, affecting the company's development.
