Problems solved by technology

Since slag contains a large amount of harmful components to molten steel, and these harmful components will return or dissolve into molten steel at any time, affecting the purity of molten steel and the quality of the final steel product. At the same time, a large amount of slag will also form different Form consumption of alloy reduces the alloy yield in the molten steel refining process

Abstract

The invention relates to the technical field of fireproof layer binders and especially relates to a guiding rod fireproof layer binder. The guiding rod fireproof layer binder comprises, by mass, 20-30 parts of propyl methacrylate, 5-12 parts of phenolic resin, 5-10 parts of diphenyl methane diisocyanate, 3-8 parts of nanometer silica, 10-15 parts of borax, 20-35 parts of silicon carbide, 8-13 parts of polypropylene fibers and 4-10 parts of hydroxy propyl cellulose. The guiding rod fireproof layer binder greatly shortens demolding maintenance time in guiding rod production, realizes a short demolding maintenance period, improves production efficiency after demolding and greatly improves guiding rod high temperature resistance.

Description

technical field [0001] The invention relates to the technical field of refractory layer bonding agent, in particular to a guide rod refractory layer bonding agent. Background technique [0002] At the end of the converter smelting, all the slag floats on the surface of the molten steel. During the tapping process of the converter, especially after most of the molten steel is removed, the molten steel at the tap hole will form a strong eddy current, and the slag will inevitably Flow out with molten steel. Since slag contains a large amount of harmful components to molten steel, and these harmful components will return or dissolve into molten steel at any time, affecting the purity of molten steel and the quality of the final steel product. At the same time, a large amount of slag will also form different The form consumes the alloy, which reduces the alloy yield in the molten steel refining process. Contents of the invention [0003] The technical problem to be solved by ...
