Buy the sowing machine accessories, the choice of the original standard is particularly important, the original standard material of the sowing machine accessories are generally smelting iron liquid, molten iron is an important part of the production of cast iron.

In general, the temperature of the molten iron is at least 500C higher than the pouring temperature, and the specific conditions of the casting structure conditions, the temperature of the molten iron should not be lower than 1380-14600C. When the need to pour special thin (2-4mm) castings, the baked temperature should be increased by 20-300C. In order to meet the needs of the sowing machine accessories, different grades malleable cast iron baked temperature should not be less than 1460-14800C.

Casting quality, including intrinsic quality, appearance quality and whether the formation of defects, etc., which are related to the iron liquid aspects of a direct relationship. Such as the flow of molten iron, thin-walled and complex structure of the castings and cold-formed defects such as the impact of molten iron temperature, and molten iron chemical composition of the composition of the requirements, the mechanical properties of the accessories have a direct impact.

The gas and non-metallic inclusions in the molten iron not only affect the strength of the cast iron and the densities of the parts of the planter, but also with the formation of pores, cracks and other defects. The temperature of the molten iron also has an important effect on the inherent quality of the sowing machine accessories, such as the quality indicators of gray cast iron.
