Abstract
The invention discloses a surface compound dope of the side sealing plate of a double-roll cast-rolling strip mill. The compound dope consists of the following components: 50 to 70 percent of black lead, 5 to 15 percent of bentonite, 10 to 15 percent of high-alumina fly, 7 to 10 percent of colophony and 8 to 10 percent of alcohol according to mass proportion. The compound dope of the invention resists the high temperature of 1500 to 1700 DEG C, has the high adhesive attraction, is hard to fall off, improves the service life of the side sealing plate, reduces the maintaining cost, ensures the commercial production in batch, increases the economic benefits and has no effects on the components and the quality of strip steel.
Description
Technical field
The present invention relates to the rolling casting technology of metallurgical industry, be specifically related to the surface recombination coating of the side seal board of double-roller rolling strip steel machine.
Background technology
The double-roller rolling technology directly pours into a pair of counterrotating casting roller by molten steel, and molten steel is crystallisation by cooling on the casting roller, draws the strip steel from two roller gaps.Excessive in order to prevent molten steel, at two roller both ends of the surface installation side shroudings, side seal board is made by refractory material, be generally high temperature melting quartz, side seal board directly contacts high-temperature molten steel, cause the side seal board lost of life, often maintain and replace makes double-roller rolling strip steel machine be difficult to carry out mass industrialized production, has reduced production efficiency.
Summary of the invention
The objective of the invention is to: a kind of surface recombination coating of side seal board of double-roller rolling strip steel machine is provided, and this composite coating is sprayed on the side seal board surface, prolongs side seal board service life, keeps mass industrialized production, enhances productivity.
Technical solution of the present invention is that this composite coating is made up of following component mass percent: graphite 50-70%, bentonite 5-15%, high-alumina fly 10-15%, rosin 7-10%, alcohol 8-10%.
Composite coating of the present invention is made by following method: at first, the porcelain container made of graphite, bentonite, high-alumina fly being put into inclination angle 15 degree rotated 60 rev/mins of rotating speeds 4 hours; Secondly, in container, add rosin, alcoholic solution, continue to stir 2 hours; At last, added water in per 15 minutes once to be coated with feed liquid up to making rheology, wherein moisture content is 20-40%.
The spraying method of composite coating of the present invention is: at first, side seal board is heated to 80-120 ℃; Secondly, paint spray gun coating is sprayed onto side seal board one side surface, coating is done the back and is continued the spray second layer, continuously until thick coating 1-2 millimeter; At last, side seal board toasted 45 minutes in the baking oven of 900-1000 degree.
Composite coating of the present invention is high temperature resistant 1500-1700 degree, strong adhesion, difficult drop-off improves side seal board service life, reduces maintenance cost, guarantees mass industrialized production, increases economic benefit, and does not influence band steel constitution and quality.
