As a steel casting manufacturing factory with rich experience, Tenfaye is well aware of the elements of quality control of steel castings. When customers choose steel castings, apart from the price factor, the most important thing they care about is quality. Whether the product can meet various restrictions during use and effectively complete the work. This article shares several factors that control the quality of steel castings.

(1) Control of chemical composition:
Subtle compositional differences can lead to vastly different properties of steel castings. Every time we make molten steel, we must ensure that it gets the composition we want. Therefore, it is essential to analyze the molten steel before pouring begins. Only after the ingredients are ensured to be qualified can pouring be carried out. If there are some compositional differences after inspection, it is generally necessary to adjust the composition of the molten steel and continuously analyze it with a spectrometer until the adjustment ratio is qualified before proceeding to the next step.
(2) Control of mechanical properties:
Mechanical properties can be divided into many types, including mechanical properties, hardness properties, etc., which affect the toughness, pressure resistance, wear resistance, etc. of the product during actual use. Generally, during pouring, we will take part of the molten steel from the same furnace and perform heat treatment in the furnace, and then make a prepared sample after mechanical processing. We can use relevant equipment to conduct subsequent testing steps of mechanical properties.
(3) Control of surface quality:
These are some of the more common problems with steel castings. Ordinary steel castings often produce defects such as cold shut, cracks and shrinkage during the casting process. The reasons are also varied, including molten steel temperature, inaccurate composition, human errors, etc. We must test the castings before leaving the factory to prevent them. Defects that affect performance.

(4) For size control:
From a 2D casting drawing to a 3D solid casting, this is an extremely complex process. Every step in the production process may cause dimensional errors and changes in the shape of the casting. Equipment such as three-dimensional coordinate and three-dimensional inspection can effectively reduce the occurrence of such errors and are an indispensable part of detecting the quality of castings.
Controlling the quality of castings is a vital process. Do not underestimate any detail, otherwise it may cause major consequences during use. We must firmly control the quality of castings and curb the occurrence of casting defects in a timely manner.
