OTPORAN NA TOPLINU LIJEVANO ŽELJEZO REŠETKA ŠIPKA
prednosti otporan na toplinu lijevano željezo rešetka traka uglavnom uključuju oksidaciju otpornost% 2c rast otpornost, visoka habanje otpornost, udar otpornost, deformabilnost i zavarljivost.
Heat-resistant cast iron grate strip shows excellent performance in high temperature environment due to its unique material and design. First, heat-resistant cast iron has oxidation resistance and growth resistance, which allows the grate strip to remain stable under constant high temperature without damage caused by oxidation. Secondly, the wear resistance of the refractory cast iron grate strip is very high, because the carbon content and chromium content in the chemical composition of the alloy layer are relatively high, the carbide wear phase is vertically distributed, and the wear resistance is more than twice that of the cast alloy. In addition, the heat-resistant cast iron grate strip also has impact resistance, deformation and weldability, can be directly processed like steel plate edge deformation, cutting, punching, the service life can be increased by 5-10 times. These characteristics make the heat-resistant cast iron grate strip become an indispensable part in the industrial grate and furnace floor and other fields, its excellent high temperature resistance and stable and reliable performance, make it can play an excellent performance in a variety of high temperature environment
