Arc model for continuous casting machine is to check whether the bending radius of the Dan detection tools meet the design requirements, while also the security of the arc model casting casting machine can one-time measurement of measuring success. 
 Because of the design of precision arc model is particularly high, usually bend radius requirements for manufacturing precision ± 0.02-0.05, plane requirements ± 0.05, parallelism requirements ± 0.03. 
 Arc model to with the installation and commissioning of various types of continuous casting machines, casting speed uniform, and to ensure no leakage of steel, keep steel, continuous casting machine should play performance.
