As a bulk raw material for industrial production, high quality and healthy and orderly development require a high quality standard system to support. However, due to the lack of necessary specifications and standards, the quality of sand aggregate products is uneven, and can not meet the requirements of high-quality development of infrastructure engineering construction in China. Through the establishment of perfect standards and standards and quality inspection and testing system, standardize the development of the industry, improve product quality, especially improve the proportion of high-quality sand and stone aggregate, and build a brand has become a top priority.
As a crusher that plays a core role in the production process of sand and stone aggregate, its quality is directly related to the quality of sand and stone aggregate. Today, the crusher market is mixed, enterprises have their own focus, each has their own advantages, the longest international brand in the market to play quality, many imitation manufacturers are at low prices to attract customers. However, the wool comes out of the sheep, the pursuit of low prices, but also to ensure the profits of the enterprise, every penny saved will eventually be reflected in the product.
Take the most commonly used processing parts of cone crusher as an example, the material can choose carbon structural steel, can also choose low alloy structural steel, and carbon structural steel is cheaper, after heat treatment, these two materials can achieve the corresponding hardness and tensile strength, but the same hardness conditions carbon structural steel yield strength is low 10%~20%, This is a cost Sisuper Saipoon cannot save.
In order to save money, let’s take a look at the mystery of the casting process, optimized casting system, expensive software costs, experienced personnel costs are very high. The way the old master leads the apprentice is very economical, but whether the location of the sprue riser is reasonable, whether the cold iron needs to be placed, and whether the setting of the inner sprue is optimal, the apprentice can only rely on the feeling.
The cost of clay sand in the casting process can be a large sum cheaper than that of resin sand modeling, but the accuracy of the casting is much worse and the surface roughness is much worse. Casting flaw detection, repair is the need for professional operation, in short, are cost ah. For castings, heat treatment is very important, parts need to heat up at different speeds under different temperature conditions, so the temperature control accuracy of heat treatment equipment is very important, otherwise, heat treatment cracking, parts decarburization, grain conversion is not ideal, of course, this is also visible cost ah.
