Ji'nan pullard Machinery Equipment Co Ltd   

I is the Jinan Prade mechanical equipment Co., Ltd., is specialized in casting, heat treatment, mechanical processing, manufacturing enterprises, can undertake parts of all types of machinery and equipment, steel, iron casting and heat treatment, mechanical processing tasks. After many years of experiments, research and absorption of the international advanced technology, the formation of the world's leading steel tissue homogenization technology.  our company developed the HG30 material after the world's famous FREIBERG Mining Industry University Institute of iron and Steel Research Institute identified as the most hard wear-resistant material in Germany and Europe, see identification certificate.  the company is a high-tech enterprise integrating scientific research, development and production. Company with international advanced new iron and steel tissue purification technology, focus on the production of tool die steel material and wear resistance, heat resistance, corrosion equipment accessories. We are professional producer of imported fine crusher, crushing hammer mill, lining board, our double metal composite hammer, for example, do you believe the reasons are as follows:  1, our liquid liquid composite technique [current domestic is a solid liquid composite technology], which can effectively reduce the fracture rate of the composite surface and use the performance more stable.  2, alloy layer, we added a higher percentage of nickel, chromium, molybdenum, manganese and other rare precious metals, increased the wear resistance and corrosion resistance. The hardness is the highest in China and Europe.  3, why our products are hard and not crisp? The answer is that we have joined the homogenization - our core technology. It is known that the performance of steel depends on the uniformity of its organization. Many micro elements such as sulfur, phosphorus, nitrogen, oxygen, tin, lead, etc., lead to the existence of impurities in the steel structure, resulting in the enrichment effect of grain boundaries in iron and steel structure, and the grain boundary segregation in different degrees. After many years of experiments, research, digestion and absorption of the international advanced technology, the success of the introduction of active elements of steel materials, steel materials to solve the problem of the matrix structure of the purification and the second phase of the enrichment effect, the development of iron and steel organization. With homogeneous agents, purification of the matrix organization, increased the wettability of internal, metallographic organization with a more detailed, so our double metal composite hammer alloy layer hardness and toughness to solve the hard brittle problem.  4, our products in ensuring quality [in the same service conditions, not less than foreign hammer, lining plate life] at the same time, the price is imported hammer and lining board 1 / 2 or less, the delivery period is 20 days. In the localization of accessories, the leader of the leadership seriously consider the use of our products, we believe that the superior performance of our products will give your business to reduce costs and create greater benefits.  the parameters of HG card head lining board Chemical composition: HG card: Hammer tungsten carbide reinforced high chromium cast iron HRC63 ~ 66 HG brand liner: chromium nickel corrosion resistant wear resistant steel HRC46 ~ 52 Service life: Corrosion resistant HG board of the service life of 3000 hours. Abrasion resistance, heat resistance, corrosion resistance, in quartz content is less than 5%, the water content is less than 7%, 6000 kcal of coal quality, brand Hg hammer service life can reach about 1500 hours.
