Witness the Pouring of the Feeding & Discharging End Cover for Ball Mill by Customer in our Foundry

Recently, the supervisor of Aojin Company visited our company, the purpose of this trip is to witness the casting of the blank of the end cover of mill feeding and discharging undertaken by our company. Before pouring, the two end covers were finished with wooden mold and sand mold. As one of the casting processes, pouring is to inject the molten liquid metal into the corresponding mold for the casting of metal parts or the forming of cement boards and concrete buildings.

The two end covers are about 3.5 meters in diameter, 1.5 meters in height and 7.5 tons in weight. They are ordered by end user from Russia with high quality and technical requirements. The friends who are familiar with hot processing know that casting temperature and time have a great impact on the quality of steel castings. In the workshop, our workers operated strictly as per the operation instructions: before pouring: workers check the equipment, the gate and riser, their labor protection and the name of the casting. During the pouring: sampling, adjusting the pouring ladle position, cleaning around area of the riser, enventing air, filling with insulation covering agent, and taking good measures to ramming riser are carefully done. After pouring, record the work note after pouring and the chemical composition of the molten steel was tested to meet the technical requirements. Finally, the customer was very satisfactory with our casting process and the quality control during the pouring. As a group company founded in 1981 and has more than 40 years of development and design, manufacturing, installation and commissioning, technical services of the whole set f machinery in mining, metallurgy, building materials, washing, shipbuilding and other fields. Our company personnel will give full play to our technical advantages and experience, under the premise of ensuring quality, scientific arrangement of production plan, keep an eye on the production schedule, to ensure the delivery of the two end caps as required.
