Abstract
The utility model relates to a reinforced steel fiber structure used in a catalytic cracking device. The reinforced steel fiber structure comprises a steel fiber body, wherein the cross section of the steel fiber body is circular, the diameter of the steel fiber body is 0.2-0.4mm, and the steel fiber body is bent into a sawtooth shape or wavy shape. After the reinforced steel fiber structure is used in a refractory castable in the catalytic cracking device, the integral bonding capability between steel fiber and the castable is greatly enhanced.
Description
Technical field
The utility model relates to a kind of reinforcing fibre that uses in catalytic cracking unit, especially a kind of reinforcement steel fiber structure.
Background technology
The normal refractory castable that adopts in catalytic cracking unit for the overall flexibility that strengthens mould material and prevent and the coming off of metal shell, increases a certain proportion of steel fiber in mould material.The steel fiber that adopts is mainly arc and crescent at present.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of reinforcement steel fiber structure that can increase the whole binding ability of steel fiber and mould material is provided.
According to the technical scheme that the utility model provides, described reinforcement steel fiber structure comprises the steel fiber body, and the shape of cross section of described steel fiber body is circular, and the diameter of steel fiber body is 0.2 ~ 0.4mm, and the steel fiber body is bent into zig-zag or waviness.
Described steel fiber body is made by Cr18-Ni8 or Cr25-Ni20 material.
After using in the refractory castable of the utility model in catalytic cracking unit, strengthened the whole binding ability of steel fiber and mould material greatly.
