[0020] 7. Since metal is easily oxidized at high temperature, compared with the traditional combustion furnace made of metal material, the combustion furnace of the present invention is cast by high temperature resistant casting material, which can keep the combustion furnace in a high temperature state for a long time without being affected, making it more stable to use and having a longer service life;
