A kind of thermal shock resistance of heating furnace roll thermal insulation layer, its characteristic is using the excellent characteristics of refractory fibre products, choose one or several products package or winding on the furnace roller roller, as the furnace roller thermal barrier.When the parcel or winding insulation blanket, spray adhesive coating of high temperature or high temperature glue, implements triple reinforcement process for thermal insulation layer.The inner layer is made up of evenly spaced welding of metal nail on roller or wrap cladding on the furnace roller roller of metal fixed network, frame to protect thermal barrier reinforcement;Middle is with refractory insulation fibre products or winding roll, reoccupy refractory insulation bandage wrapped fiber rope, protect and reinforce the dual role.Outer layer with high temperature glue or adhesive coating, and refractory fiber of adiabatic insulation layer.When necessary, can also be used in refractory insulation fibre winding heat resistant alloy wire;The overall structure of the internal heat thus formed just outside, triple reinforce protection.
