Casting Grinding sections from China supplier

Specifications

Product Process Features:
1, the chemical composition matches: The chemical composition is reasonable Ningguo Nan Fang company all researchers through years of exploration and gradually formed optimal control curve, has a unique chemical composition matching method so that it can better serve the combination of toughness and hardness, to achieve the best condition.
2, the melting process characteristics: Quenched by electric melting material segregation and effective solution to the problem of composition control, to ensure the quality of steel, give full play to the melting furnace melting capacity and the ability of harmful gas emissions.
3,temperature control process characteristics: Temperature control process is the production of chrome cast ball a very important and complicated process, different tapping temperature, pouring temperature, the mold temperature and the heat treatment temperature, the reaction is very sensitive to the quality of products, to master the appropriate pouring temperature, the mold temperature, the product from the liquid to the solid state process to achieve a good level.
4, the molding process characteristics: In the pouring temperature and mold temperature at 1500 °C when the pouring temperature, internal organization can make the product more compact grain refinement and make carbide radial arrangement, in the grinding work, this carbide embedded in a matrix again, continue to form rigid layer, so that the hardness and toughness to maintain a reasonable rendezvous point, greatly improving the toughness and hardness casting ball combination.
5, the heat treatment process characteristics: Using automatic production line oil quenching, quenching, tempering, it burned through, quenching penetration can reach the abrasive material matrix is not broken, without losing a round, wear coefficient characteristics.
6, the detection means: There are direct reading spectrum analyzer, automatic carbon detector, high-altitude drop ball tester, metallurgical microscope and other equipment to track testing to ensure that substandard products not manufactured.
