一种抗结焦合金材料及其制备方法和一种抗结焦裂解炉管
摘要：
本发明涉及抗结焦领域，具体地，涉及一种抗结焦合金材料，一种制备该抗结焦合金材料的方法以及一种抗结焦裂解炉管。所述抗结焦合金材料包括合金材料基体和涂覆于该合金材料基体表面的涂覆层，所述涂覆层中含有所述合金材料基体中金属元素的金属氧化物和金属硫化物，相对于所述涂覆层的体积，所述金属氧化物的含量为75.1‑85体积％，所述金属硫化物的含量为15‑24.9体积％。本发明的抗结焦合金材料能够有效地抑制结焦并且能够较长时间保持抗结焦性能。
摘要（英）：

The invention relates to the field of anti cocking, in particular to an anti-cocking alloy material, a method for preparing the anti-cocking alloy material and an anti-cocking cracking furnace pipe. The anti-cocking alloy material comprises an alloy material matrix and a coating layer, wherein the surface of the alloy material matrix is coated with the coating layer. The coating layer contains metallic oxides and metal sulfides of metallic elements in the alloy material matrix. Relative to the volume of the coating layer, the content of the metal oxides is 75.1-85 vol.%, and the content of themetal sulfides is 15-24.9 vol.%. The anti-cocking alloy material can effectively inhibit coking and can maintain anti-cocking performance for a long time.
