At present, the aluminum-zirconium carbon skateboard on the market adopts the traditional carbon combination. Although it has the characteristics of good thermal shock performance and high strength, it is easy to cause carbon oxidation when casting some special steels, resulting in loose structure of the skateboard, reduced strength and slippage. The phenomenon of lama in the district is not strict. Based on the traditional non-burning high-performance skateboard application, Chengding uses self-developed composite carbon materials and composite antioxidants to better solve the thermal shock stability problem of traditional non-burning high-performance skateboards, basically avoiding the lower skateboard. The phenomenon that the sliding zone is off the block has the following remarkable features:
The carbon content of the skateboard is low, and there is little phenomenon that the carbon-containing slide plate is pulled by a large area due to oxidation, and is more suitable for casting of low carbon steel and ultra-low carbon steel;
The high temperature strength of the skateboard is high, which reduces the large reaming of the skateboard when it is repeatedly slipped;
The thermal shock stability is good. When used, the crack is small, which basically eliminates the phenomenon of falling off the sliding area of the lower skateboard and ensures the safety when casting steel.
Add special compound carbon source to reduce the oil immersion process, which is conducive to environmental protection and improve the working environment of workers.
