In the present embodiment, described stainless steel tube CO2Laser instrument includes the sealing stainless steel tube as negative pole and shell body；One end soldering of described sealing stainless steel tube has total reflective mirror pedestal, and described total reflective mirror pedestal is provided with total reflective mirror；The other end soldering of described sealing stainless steel tube has outgoing mirror pedestal, and described outgoing mirror pedestal is provided with outgoing mirror；Described sealing rustless steel inner coaxial tube be provided with interior discharge tube, described interior discharge tube is provided with sparking electrode.Described stainless steel tube has double-deck inwall, has water-cooling sandwich between described inwall；Described interior discharge tube has double-deck inwall, has water-cooling sandwich between described inwall.Described stainless steel tube CO2The power of laser instrument is 100～500W, preferably 200W.Use stainless steel material to be possible not only to improve mechanical strength as shell in the present embodiment, and be conducive to heat radiation, work efficiency can be improved.
In the present embodiment, described metal mesh belt needs to have concurrently good tensile property, toughness, and surface needs to have high rigidity, resistance to heat affecting concurrently, to improve the service life of metal mesh belt and to improve the surface quality of reflective tape.It addition, in order to prevent reflective tape from skidding, its surface needs certain surface roughness.From economic considerations, described metal mesh belt is preferably cast iron guipure.Specifically, described cast iron guipure comprises the Mg of the Zr of the Ti of the Cu of Mo, 0.60-1.0wt%, 0.05～0.15wt%, 0.01～0.05wt%, 0.02～0.05wt% of Mn, 0.02-0.10wt% of Si, 0-0.8wt% of C, 2.5-3.5wt% of 3.1-3.8wt%, the P of below 0.10wt%, the S of below 0.05wt%, and the Fe of surplus and inevitable impurity.The content of described Mo is preferably the Mo of 0.02-0.08wt%.In the present embodiment, C is the important element forming graphite cast iron, be conducive to taking into account tensile strength and ductility in the range of 3.1-3.8wt% by the content of C, if the content of C is more than 3.8wt%, plasticity and processability will be caused to reduce, if and the content of C is less than 3.1wt%, it will cause intensity not enough.The addition of Si is not only necessary to formation spheroidal graphite cast-iron, and the addition of Si is also beneficial to improve thermostability and the oxidative resistance of spheroidal graphite cast-iron.When the content of Si is less than 2.5wt%, it will cause the thermostability of cast iron and oxidative resistance to significantly reduce, and when the content of Si is more than 3.5wt%, the ferritic phase of matrix will become fragile, and causes ductility to deteriorate.Mn is the effective element of sulphur removal, if but the addition of Mn is more than the toughness that may affect cast iron during 0.8wt%.Although Mo can be obviously improved oxidative resistance and be effectively improved intensity, but the membership that adds of Mo causes processability to significantly reduce, and also results in ductility reduction.Therefore, in the present embodiment the addition of Mo is strictly limited in below 0.10wt%, preferably below 0.08wt%；In order to improve intensity, and resistance to elevated temperatures, wherein contain the Ti of the Cu of 0.60-1.0wt%, 0.05～0.15wt%, with 0.01～0.05wt% Zr, especially meet when the weight percentage of Cu, Ti and Zr: during 4.2≤[Cu]/([Ti]+2 [Zr])≤5.0, both can obtain good thermostability and oxidative resistance, and high-strength and good processability can also have been had concurrently.P and S is the impurity element in cast iron, when the content of P is more than 0.1wt%, is susceptible to embrittlement, and when the content of S is more than 0.05wt%, thermal stress will likely result in brittle cracking.As exemplarily, the raw material prepared use intermediate frequency furnace is carried out melting, and smelting temperature is 1500～1550 DEG C, is placed on bottom ladle by nodulizer (Fe-Si-Mg alloy), making molten iron convection current carry out spheroidising, the time of spheroidising is preferably 3～5 minutes；The cast iron obtained after cast was 720-850 DEG C of stove inside holding 2.0～3.0 hours, and then stove is cooled to 500～600 DEG C and is incubated 8.0～10.0 hours, and air cooling is to room temperature.Following present as example and the composition of the spheroidal graphite cast-iron of comparative example, as shown in table 1.
