Converter oxygen lance anti-sticking steel slag refractory coating

Abstract

The invention relates to a converter oxygen lance anti-sticking steel slag refractory coating, which comprises the following raw materials in parts by weight, 15 parts of dimethyl ketoxime, 20 parts of a silane coupling agent, 5 parts of a dispersant, 8 parts of an epoxy resin heating curing agent, 22 parts of lead white, 21 parts of silicon resin, 5 parts of toluene and 4 parts of a pre-filming agent. The raw materials are mixed and uniformly stirred to obtain a finished product. The coating belongs to a ready-to-use type, two forms of spraying and painting are adopted, the use method is verysimple, spraying or painting is conducted three times, and spraying or painting is conducted every 15 minutes, and after being sprayed and coated on the surface of the oxygen lance, a layer of an isolating membrane which has a smooth surface and is not easy to adhere to steel slag can be formed, and the isolating membrane can be continuously used for 3-5 hours at the high temperature of 1700-2000DEG C, so that the working intensity of field coating personnel can be reduced.

Description

technical field [0001] The invention relates to a refractory coating, in particular to a converter oxygen lance anti-sticking steel slag refractory coating. Background technique [0002] Converter oxygen lance anti-adhesive steel slag refractory coatings can be divided into organic coatings and inorganic coatings according to the basic composition, can be divided into normal temperature coatings and high temperature coatings according to the degree of fire resistance, and can be divided into ordinary coatings and special coatings according to performance. [0003] CN100487067C discloses an anti-sticking slag coating, which belongs to the refractory material with physical properties, and cannot be operated continuously. After each painting, it can only maintain one operation, and it needs to be painted again for another operation. , which greatly affects the continuity and efficiency of the operation. At the same time, the repeated brushing operation artificially increases th...
