Currently, most of the enterprises utilize the round bar steel rolled by the steel mill as the steel grinding rod directly. The round bar steel has very low hardness of only 12HRC to 25HRC, and the internal stress, leading to broken damage easily and low wear resistance property. Meanwhile, the round bar steel comes with some defects such as loose and not compact internal structure. Just because of that, using the round bar steel for grinding would cause a series of problems such as large wear, easily bending, breaking, winding, two tapering ends, low productivity, failing to reach the expected qualified rate, heavy workload of the follow-up magnetic separation process, etc. Features 1.The wear resistant effect of the new-type alloy wear resistant steel grinding rod is 1.5 to 2 times stronger than that of the rolled steel bar. Marked by excellent wear resistant property, the product can save a lot of cost for the customer. 2.It is manufactured by using the latest production method. The dimension and the specification can be adjusted in accordance with the requirements of the customers. The largely improved flexibility can save the unnecessary waste. 3.The product can serve for a longer time, economize the production cost and mitigate the labor intensity of the workers. Moreover, it eliminates the need for stopping the rod mill to add the new steel grinding rod every day, which is conducive to largely enhancing the productivity. Our domestic clients are full of praise for the product. Our product order process would follow the steps below. 1.Communicate with the customer to understand the requirements of customers to the product regarding length, diameter, quantity, etc. 2.Order the raw material from the steel mill. 3.Carry out the inspection for the incoming raw material. 4.After being inspected to be qualified, the raw material is processed with professional quenching and high temperature tempering, heat treatment, straightness adjusting, and others by using the professional equipment and technology. 5.Inspect the finished steel grinding rod about the hardness, impact value, drop test, etc. 6.After being approved, all the finished products are stored into the warehouse for delivery.
The forged steel grinding ball is excellent in surface quality, toughness, and resistance to impact and abrasion. It won't crack and lose circularity easily. The forging and stamping method that we use is that heating the metal until the temperature reaches 1050ºc (±50 ºc), and utilizing the metalforming machinery to exert pressure onto the metal blank, then the metal blank coming out with plastic deformation to become the forge piece with certain mechanical properties, shape and dimension. The forging can eliminate the defects such as porous as-cast microstructure generated during the smelting process of the metal, and optimize the microstructure. Meanwhile, as a result of the preservation of the complete metal flow line, the forge piece has superior mechanical performance to the casting with the same material. The forged steel grinding ball must use the super wear resistant material to ensure the abrasion resistance, such as the high-carbon steel materials compliant with the national standard, or the high wear resistant alloy steel material researched and developed independently by some companies themselves.
