Today, our ecological environment has been severely damaged. Under the state's efforts to supervise environmental protection, the raw materials used by large-scale steel castings manufacturers have been continuously increasing, and some raw materials have risen as high as 10%-20%. At present, some small cast steel plants have made changes in the raw materials in order to reduce the price of steel castings, which has resulted in poor quality of cast steel and severely affect the normal use of equipment.
Taking the common hollow shaft as an example, if the casting material fails to meet the requirements or the casting process is not rigorous, after a period of wear, it will cause cracks in the hollow shaft, and even a broken condition. The time-consuming maintenance work will also affect the work efficiency. . What are the details that need to be taken into account when casting a hollow shaft?
First of all, the rounded corners of the end of the hollow shaft of the ball mill are stress concentration sites. This site is prone to blisters, pores, and micro-crack defects at the time of casting. Therefore, there must be no casting defects such as porosity and trachoma.
Secondly, in the processing, the part in contact with the spherical tile needs to be processed after grinding to ensure accuracy and finish.
When Luoyang Yujie processes steel castings, it uses a unique heat treatment technology and casts high-strength steel to provide users with cost-effective hollow shafts. It strictly follows the GB 2 level inspection standards and performs a 360° nondestructive testing system. Ensure that the steel castings are of reliable quality and have a long service life.
Luoyang Yujie faced the continuous rise of raw materials, seized from the production workshops, and controlled the waste of raw materials and saved production costs under the condition of guaranteeing quality. The quality of the produced steel castings was guaranteed and was praised by customers as “high cost-effective casting. Steel manufacturer."
