Problems solved by technology

[0004] In actual use, due to the inevitable contact between the slide lubricating coating and the air, and the graphite in the coating is prone to oxidation and consumption at high temperatures, the working life of the coating is reduced. At the same time, due to the consumption of the coating, It also accelerates the erosion of molten steel and slag on the nozzle of the skateboard

Abstract

The invention discloses a sliding plate lubricant coating sliding plates of a sliding gate system of a steel ladle and a tundish to reduce the friction coefficient between the sliding plates. The sliding plate lubricant comprises the following components in parts by weight: 2-4 parts of xanthan gum, 2-4 parts of guar gum, 0.1-0.5 part of sodium polyacrylate, 2-5 parts of styrene-acrylic emulsion, 85-90 parts of water, 0.5-1 part of sodium bentonite, 0.1-0.5 part of tween, 5-10 parts of sodium silicate, 5-10 parts of potassium silicate, 5-10 parts of sodium dihydrogen phosphate, 5-10 parts of carbon black, 0.1-0.5 part of isothiazolinone, 2-5 parts of boron carbide and 25-35 parts of crystalline flake graphite. The sliding plate lubricant is prepared by stirring and ball-milling. The sliding lubrication and the high-temperature oxidation resistance of the sliding plates can be improved by virtue of the sliding plate lubricant.

Description

Technical field [0001] The invention relates to a sliding plate lubricant for a sliding nozzle, in particular to a water-based lubricant that can improve the surface lubrication and high-temperature oxidation resistance of the sliding plate, and a preparation method thereof. Background technique [0002] Now most of the ladle and tundish at home and abroad are equipped with sliding nozzle system. The skateboard brick is a key component of the sliding nozzle, it is a component that directly controls the molten steel and determines the function of the sliding nozzle. The manufacturing process of the skateboard is different from the previous refractory materials. It has the function of molten steel injection and flow adjustment. In addition to the processes of mixing, forming, firing, and inspection, the manufacturing of bricks also includes mechanical processing of the sliding surface, installation processing and external Overall adjustment process. During use, due to the long-te...
