The invention relates to an ambient self-drying high-temperature burning sticking preventing coating which solves the problem of steel slag burning sticking prevention on the external surface of an oxygen blow pipe of a steel furnace. The high-temperature burning sticking preventing coating comprises the following components: 3.0-8.0% of silicon acrylic emulsion, 15.0-25.0% of graphite, 1.0-5.0% of molybdenum disulfide, 1.0-3.0% of rare earth cerium fluoride, 5.0-10.0% of metallic oxide, 1.0-3.0% of aerosol, 0.1-0.2% of potassium pyrophosphate and the balance of water, wherein the metallic oxide is a mixture of two or three compounds selected from antimony trioxide, copper oxide and aluminum oxide in any proportion. A coating layer prepared by using the high-temperature burning sticking preventing coating has good sticking force and excellent burning sticking preventing function and protection function on a metal base, the coating layer can be rapidly self-dried at room temperature. The oxygen blow pipe can complete 1 to 3 times of oxygen blowing process by painting the high-temperature burning sticking preventing coating on the external surface of the oxygen blow pipe once, and the external surface of the oxygen blow pipe is not stuck to steel slag or a little steel slag is burned and stuck.
Description
technical field [0001] The invention relates to a high-temperature self-drying anti-stick coating at room temperature. Background technique [0002] The oxygen blowing tube is a self-consumable oxygen blowing tool that is inserted into the molten pool from the furnace door to blow oxygen during steelmaking. It has been widely used as the main oxygen blowing tool in the production of electric furnaces and some open hearth furnaces in my country. . Oxygen blowing requirements for steelmaking are very harsh, usually the oxygen blowing pipe is inserted into the surface of the molten steel pool with a temperature above 1600°C, a molten steel bath is usually equipped with two oxygen blowing pipes, and the two oxygen blowing pipes are used in turn with an interval of 30- 40 minutes. When the oxygen blowing pipe completes an oxygen blowing process of about 20-30 minutes, the entire outer surface of the oxygen blowing pipe is covered with molten steel and steel slag. The labor inte...
