Manufacturing process of Shandong Province, Shandong xianjin mining equipment Co., Ltd


1.Shot: a surface treatment, according to the need to adopt a certain diameter steel stylus on the surface of parts, the formation of small pits uniform, in order to improve the surface fatigue strength of chain.
2.Bluing: the temperature is heated to certain parts, chemical solution after cooling, saponification, the parts of the surface color blue. Through the chain bluing of beautiful appearance, and anti rust effect. Is the inadequacy of these chemical solution caused great pollution to the environment.
3.Phosphate: Part immersion phosphating solution at a certain temperature, so that the formation of phosphate layer on the surface of parts, the parts of the surface color is black or grey, improve the chain beautiful at the same time to reach the purpose of preservation. The phosphating solution can be recycled, the environmental pollution is light.
4.Nickel: by electroplating or chemical nickel plating, nickel plating layer formed on the surface of parts, plating layer can be beauty chain, and anti-corrosion. Nickel plated chain is generally used in outdoor occasions.
5.Method: using zinc electroplating and chemical plating, zinc layer formed on the surface of parts, galvanized layer can be beauty chain, and anti-corrosion. Galvanized chain is generally applicable to the open place.
6.Heat treatment: in the heat treatment equipment, using a variety of auxiliary medium at high temperature, improve the structure of parts, improve various physical properties.
7.Carburizing: part of the heat treatment equipment in the heated to a certain temperature and heat preservation time, then the carbon containing medium, the carbon into the surface of parts, in order to improve the hardness and wear resistance of the chain.
8.Quenching: the parts in the heat treatment equipment after heated to a certain temperature, heat preservation time, and then in accordance with the requirements of cooling in different medium, thereby improving the hardness of parts.
9.Backfire: after quenched parts in the heat treatment equipment in a certain temperature and heating, cooling and heat preservation time. Parts after tempering can reduce the quenching hardness, eliminate quenching stress, improved toughness.
10.Oil: oil can prevent rusting of the chain chain, but also more luster.
11.Fat: fat on the chain can prevent rusting of the chain, and more luster. (grease used in maintenance inconvenience oiling,)
12.Stainless steel: no oil and grease, cleaning and hygiene. Suitable for the food industry.
13.Two processes: chain using two patent technology, can make the chain at the initial stage of use can avoid wear of chain transmission, and ensure the efficient anti rust anti-corrosion performance, do not need regular maintenance, long life.
