Hunan Fengwei Wear Parts Foundry was founded in the beginning of reform and opening up, is a condensation of the wear parts production enterprises of several generations of painstaking professional. Through the efforts of several generations, the enterprise has entered a new period of rapid development of.2013 enterprise through the German ISO9001:2000 certification in Rhine, and won the first manufacturing China wear-resistant materials industry “Global Award”.

Take the hammer crusher as a hammer, and its production process is reasonable, seriously affecting the crusher’s work efficiency and production capacity, so we must choose the appropriate production process

Most of the material is made of high chromium wear-resistant cast iron, high chromium cast iron has good flow, larger shrinkage, large tendency to crack, so it can extend the service life of hammer head and lining board

1, the casting process of hammer head and lining board

Through the comparison of various elements of burning cupola and medium frequency furnace melting process, the chromium in the cupola burning is too large, and other elements in the melting process is difficult to control, so the use of intermediate frequency furnace molten iron, the melting temperature is 1450 degrees Celsius, the pouring temperature is 1320 ~ 1360 degrees. The pouring temperature is too high will the casting properties of coarse grain, unfavorable; very low pouring temperature, casting surface cold septum, wrinkled skin. In addition, hammerhead and cleading should focus on riser system on the casting process, the iron level steadily filling casting and have good feeding.

2, heat treatment of hammer head and lining board

Heat treatment is the important process of high chromium cast iron casting obtain excellent wear resistance, so the casting must be quenched and annealed in annealing. After cleaning can eliminate the internal stress generated during casting, increase the plasticity and toughness of casting matrix; quenching can make the abrasion resistance of high chromium cast iron to obtain martensite, the hammerhead and cleading to obtain high abrasion resistance. In the heat treatment process, heating heating furnace to maintain the temperature in uniform and warming up slowly, to prevent the parts from cracking during the heating process.

3, product advantages:

  • Hunan Fengwei Wear Parts Foundry hammer, super wear resistance, strong impact resistance, life expectancy;

  • Hunan Fengwei Wear Parts Foundry hammer is good in toughness and difficult to break. It has high reliability and high safety factor;

  • Hunan Fengwei Wear Parts Foundry human services: Hunan Fengwei Wear Parts Foundry wearable parts can be customized to map, and if there is no map, the company has professional mapping personnel to help you mapping, after customization
