In the heat treatment process, the reject rate caused by the quenching process is usually higher. This is mainly in the quenching process, and at the same time, the formation of greater thermal stress and structural stress, in addition, it is easy to be exposed in the quenching and tempering process because of the inherent […]
1. Take a pinch. 2. Exhaust. 3.Slag collection. 4.Logo for the metal filling cavity. Casting riser is a part designed to supply the shrinkage of casting during solidification to prevent shrinkage cavity and shrinkage porosity.
High Chrome cast iron containing 12.30% chrome and 2.4-3.6% carbon can be highly alloyed and heat treated to obtain martensite or austenite or mixed matrix and special carbides of chrome. This particular carbide is a hexagonal system of Me7C3 with hardness as high as HVL200. 1600, much higher than the cementite type of carbides and common mineral […]
This company is a large state-owned enterprise, the production of many varieties of gray iron castings, the previous use of Cupola melting equipment, the production of gray iron castings have been very stable quality. In order to further implement the national requirements for Energy Conservation and emission reduction, optimize the environment, and achieve high efficiency […]
In the traditional production process of ductile iron, about 10% carbon scrap is generally used for the burden. This paper only deals with some problems that should be paid attention to in the process of producing nodular cast iron in an induction furnace after increasing the proportion of carbon scrap used. According to the production […]
