The invention discloses a low segregation centrifugal casting high speed steel roll and the method. The roll is constituted by high speed steel roll body and alloy ductile ion roll core. The roll is produced by electric furnace. The high speed steel roll body is cast on horizontal centrifuge. As the liquid steel is cast iron powder suspension concentrate with 4%-6% by weight of liquid steel is added. After the liquid steel is cast glass waste sludge is added and then it is cooled by spraying water to form the model. Meanwhile the rotate speed of casting model is changed continuously and finally the ductile ion roll core is cast at the top statically. There is no obvious element segregation in radial section of high speed steel roll manufactured in invention. The macro hardness of roll is high and can achieve 63-65HRC. The difference of roll face hardness is less than 2HRC. The hardness fall of roll along the radial direction is small. The tensile strength of roll body is more than 600MPa and the elongation of roll core is more than 3%. The service life is improved by 5-8 times than high chromium cast iron roll and is improved by 35%-48% than common high speed steel roll. It can decrease the producing cost of rolling steel and prolong roll changing period.

The invention provides a transparent halogen-free fire-retardant paint composition, which consists of 100phr (Parts per Hundred of Resin) of adhesive, 50-400phr of solvent, 50-300phr of foaming agent, 10-200phr of carburetant, 1-100phr of carbonizing promoter and 0-100phr of auxiliary additive; wherein, the carbonizing promoter is a phosphorus-containing compound with reaction functional groups.
