Summary: | The invention provides an aluminothermic agent as well as a preparation method and a use method thereof. The aluminothermic agent comprises the following components in parts by weight: 35-45 parts of aluminum, 40-60 parts of metal oxide, 0.1-5 parts of Ba (NO3) 2, 0.1-5 parts of a low-boiling-point gas production coating agent and 4-10 parts of Ni, or 35-45 parts of aluminum, 40-60 parts of metal oxide, 0.1-5 parts of Ba (NO3) 2 and 0.1-5 parts of low-boiling-point gas production coating agent; wherein the metal oxide comprises at least one of Fe2O3 (ferric oxide), CuO (cupric oxide), Cu2O (copper oxide), PbO2 (lead oxide) and W2O5 (tungsten oxide). The preparation method comprises the following steps: weighing the corresponding raw material components in the aluminothermic agent; and drying and uniformly mixing the thermit agent, and pressing to obtain the medicine column. The use method comprises the following steps: detecting and determining the sticking point position of a stuck tubular column by using a |
