Abstract
The invention discloses a centrifugal casting roller paint with high stability. The paint comprises, by mass, 10 to 12 parts of zirconium silicate powder, 8 to 10 parts of quartz powder, 5 to 10 parts of bauxitic clay, 8 to 10 parts of diatomite, 1 to 2 parts of mixed viscous glue and 60 parts of water, wherein the mixed viscous glue is a mixture composed of silica sol, carboxymethylcellulose sodium, sodium alkyl benzene sulfonate, sodium sulfate, n-butanol, n-octyl alcohol and fatty alcohol polyoxyethylene ether. The roller paint does not crack and shed at a high temperature, has high strength, can effectively prevent oxidation of high-temperature liquid metal, does not undergo a chemical reaction during contact with a casting mold and high temperature liquid metal and is capable of preventing generation of gases like nitrogen, sulfur and carbon.
Description
Technical field
The invention belongs to casting technology field, be specifically related to a kind of centrifugal casting roller coatings.
Background technology
Roller coatings plays an important role in roll produces, and crackle is had very big impact.Under the effect of external force or thermal stress, roller cold type can deform, and can produce inner surface cracks or pit under serious conditions, and the paint thickness of cracks will more than region about.Cold mould cracks metal due to heat conduction velocity little, setting rate will be less than other positions, and the metal of such cracks will be subject to the effect of shrinkage stress and produce the crackle consistent with cold mould surface cracks.And the effect of coating adjusts rate of cooling exactly, to reduce the molten iron thermal shock to cold mould.If coating has coming off or in uneven thickness of local, the local heat conduction velocity thin at coating is fast, and the local speed that coating is thick is slow, then molten iron can shrink uneven and crack after pouring into cold mould equally even causing uneven in temperature.If coating is blocked up, under the effect with the friction and centrifugal force of molten iron, coating can become cracking or peel off, and in the process of roll solidification, can crack equally.Centrifugal casting roller coatings poor stability conventional at present, easy to crack in using, affect roll quality and coating cleaning comparatively difficulty, additionally health is also had a certain impact.
Summary of the invention
For the above-mentioned technical problem overcoming prior art to exist, it is an object of the invention to, it is provided that a kind of high stability centrifugal casting roller coatings, do not ftracture, do not fall off under high temperature, intensity is high, and can effectively prevent high-temp liquid burning, good stability.
High stability centrifugal casting roller coatings provided by the invention, the mass fraction of coating is composed as follows: 10～12 parts of zirconium English powder, silica flour 8～10 parts, bauxite 5～10 parts, 8～10 parts of kieselguhr, add 1～2 part of mixing cohesive glue, described mixing cohesive glue composition is the mixture of Ludox, sodium carboxymethyl cellulose, sodium alkyl benzene sulfonate, sodium sulfate, n-butyl alcohol, n-octyl alcohol, fatty alcohol-polyoxyethylene ether, adds water 60 parts.
High stability centrifugal casting roller coatings provided by the invention, it has the beneficial effects that, deposits and transportation safety, and the resting period is long；There is good thermostability, chemical stability and adhesiveness；The amount of gas evolution from the coating is few, has good suspension, preserves and does not precipitate in use procedure；There is good mobility.
Detailed description of the invention
Below in conjunction with an embodiment, high stability centrifugal casting roller coatings provided by the invention is described in detail.
Embodiment
The high stability centrifugal casting roller coatings of the present embodiment, the component proportion of coating is as follows: 10Kg kieselguhr, 12Kg zirconium English powder, 8Kg silica flour, 10Kg bauxite, 1.5Kg compound viscosity glue, Ludox in described compound viscosity glue, sodium carboxymethyl cellulose, sodium alkyl benzene sulfonate, sodium sulfate, n-octyl alcohol, fatty alcohol-polyoxyethylene ether proportioning be 3:2:2:1:1:1, surplus is water, agitated, grind and sieve after namely obtain this coating.
Not ftractureing under this roller coatings high temperature, do not fall off, intensity is high, and can effectively prevent high-temp liquid burning, with not chemically reactive in casting mold and high-temp liquid metal contact process.The generation of the gases such as nitrogen, sulfur, carbon can be prevented simultaneously.
