What are the advantages of lost foam casting?

What are the advantages of lost foam casting?

发布时间 : 2020-03-14 点击 : 0
  Lost foam casting (also known as solid casting) is a combination of foam models that are similar to the size and shape of the casting to form a model cluster. After brushing with refractory paint and drying, it is buried in dry quartz sand and vibrated in shape. A new casting method that vaporizes the model, occupies the position of the model, and solidifies and cools to form a casting.   Compared with the traditional casting technology, lost foam casting has the following characteristics: 1. Good casting quality and low cost; 2. Unlimited material and suitable size; 3. High dimensional accuracy, smooth surface, reduced cleaning, saving machining; 4 , Internal defects are greatly reduced, and the organization is dense; 5, large-scale and large-scale production can be achieved, and the automated assembly line is more environmentally friendly. 6, can greatly improve the operating environment, reduce labor intensity, reduce energy consumption.   The process of lost foam casting is as follows: one: process design; two: model making, technicians make wear-resistant casting models according to drawings and connect them into strings. 3: molten steel molten; 4: chemical composition of spectral analysis; 5: pouring; 6: heat treatment; 7: hardening treatment of quenching liquid; 8: tempering 1000 ° C; 9: mechanical processing; 10: hot shot blasting; 11: testing hardness Twelve: packaging;

  The chromium-manganese dual-liquid composite hammer head is an advanced technology in the current domestic foundry industry. The following paragraphs need to be understood and understood when casting dual-liquid composite hammer heads:   The wear-resistant hammer head has been developed for many years, and it has shown a good development trend, and its wear resistance has been the focus of people's attention. As we all know, chromium metal is a wear-resistant material with excellent anti-wear properties, but its toughness is low and brittle fracture is easy to occur. In order to make the high-chromium cast iron operate safely, a composite hammer head was developed, that is, high-chrome inlay is cast on the bottom of high-manganese steel or low-alloy steel hammer, that is, the working part of the hammer head is made of high-chromium cast iron, and the hammer handle part is made of carbon steel. The combination of the two makes the head of the hammer head part have high hardness and high wear resistance, while the hammer shank part has high toughness. It takes full advantage of the two materials to overcome the shortcomings of a single material. The combination of toughness and wear resistance is One, making the product wear-resistant and not broken, is the perfect combination of steel and iron, so that the product has good comprehensive properties such as wear-resistant, impact resistance, safety and reliability. In the cement industry, the service life of broken cement clinker is higher than that of high-manganese steel. The hammer head is raised several times.   Henan Jinyu Wear-resistant Material Technology Co., Ltd. is a professional manufacturer of wear-resistant materials. It is a top manufacturer in Henan Province and the domestic industry. It has a complete management system and a complete quality inspection system, which can provide customers with high-quality, high-performance Various types of castings.
What are the advantages of high chromium alloy hammers compared to traditional forged hammers?

  The hammer head is the main accessory of the hammer crusher. The wear of the hammer head is mainly caused by the friction between the hammer head and the material. In the traditional process, the material of the hammer head is forged with manganese steel, just like a train wheel. Forging is very hard after being beaten and quenched and heat-treated. Generally speaking, it is like the utensils made by ancient blacksmiths. However, the serious defect of the hammer head produced in this way is that it is easy to heat and not wear, not to mention the high-speed rotation like a hammer Under the conditions of high temperature caused by friction, hammer heads produced by forging have been gradually eliminated.   Today, the rapid development of manufacturing industry, Henan Jinyu Wear-resistant Materials Co., Ltd. advances with the times, and cooperates with Zhengzhou University and Zhengzhou Machinery Research Institute to form a professional grinding high-tech development group, in which high-chromium alloy casting hammers are developed. The high-wear-resistant products researched and produced by the group have been enthusiastically sought after by the majority of users. What are the advantages of high-chromium alloy hammers?   Chrome: hard texture, wear-resistant, heat-resistant, is a good hammer material. The melting point of chromium is 1857 degrees, heat resistance, wear resistance, hard and oxidation resistance. Chromium is heat-resistant for stainless steel superalloys and heating alloys. The chromium content of hammers produced by our company is above 26% according to national standards. The high chromium hammerhead has high hardenability due to the content of chromium and carbon. The hardenability is better than medium chromium alloy wear-resistant steel and low alloy wear-resistant steel. After pouring, it is quenched by a quenching furnace. Hammer heads with large wall thickness can add alloy elements such as molybdenum and nickel to further improve hardenability. The mechanical properties of high chromium steels vary greatly due to the different carbon content, which provides conditions for reasonable selection of wear conditions. The high chromium hammer head has the advantages of high temperature resistance, corrosion resistance, fatigue resistance, high wear resistance, long service life, etc. It is an ideal choice for metallurgy, mining, chemical, cement and other industrial sectors.   Of course, there are many types of hammer heads. It is a wise choice to use alloy hammer heads of different materials under different working conditions. Choose Jinyu, choose the most professional production team, and win step by step for your continuous and efficient production.
