Description
Technical field
The invention belongs to band steel coating field, be specifically related to a kind of coating machine for the coating of silicon-steel magnesium oxide masking liquid.
Background technology
After orientation silicon steel carries out decarburizing annealing in continuous oven, upper surface and lower surface being with steel is needed evenly to apply magnesia masking liquid.Magnesia mainly plays interleaving agent, to prevent band steel in the adhesion of high annealing stage, simultaneously can remove the impurity such as nitrogen in steel, sulphur, in addition will with the silicon dioxde reaction of surface of silicon steel, form excellent magnesium silicate insulating bottom layer.Therefore, the quality of the coating quality of magnesia masking liquid on orientation silicon steel surface to silicon steel product plays vital effect.
At present, magnesia masking liquid is applied by double-roller type coating machine.This double-roller type coating machine comprises coating roller, lower coating roller, pallet, magnesia is coated with liquid circulating device and the magnesia masking liquid be coated with by magnesia in liquid circulating device is injected into the jet pipe being with steel upper surface; This lower coating roller is immersed in pallet, and jet pipe enters in pallet after being ejected into the magnesia masking liquid overflow of band steel upper surface, and this lower coating roller utilizes the magnesia masking liquid in pallet to carry out being with the coating of steel lower surface.
But because magnesia masking liquid recycles in process in coating, the magnesium oxide solution flowing in pallet is not smooth, and magnesia and water react and forms magnesium hydrate precipitate, generate the magnesium carbonate of easily precipitation after the carbon dioxide of magnesium hydroxide in air is combined.Magnesium carbonate and magnesium hydroxide mobility very poor, easily produce reunion depositional phenomenon.Therefore, in pallet, masking liquid mobility is not high, As time goes on, masking liquid easily produces accumulation fouling, causes lower coating roller coating quality poor, rolls occur width, quantity two-wire bar not etc. to plate face batch along band steel, and the lower coating roller of wearing and tearing, directly cause product quality defect.Also need time serious to shut down and change coating roller, the blocking of cleaning circulating line, the fouling of process pallet etc.These unfavorable factors significantly increase the labour intensity of worker on the one hand, disturb on-the-spot continuous prodution on the other hand, directly affect production efficiency, simultaneously because the magnesia masking liquid after solidification is bonded in pallet and cannot uses, not only clean difficulty, but also cause magnesia to waste.In addition, because paint roller edge gets rid of liquid, affect coating quality, disturb coating machine work simultaneously, cause paint roller edge incrustation, steel edge portion is applied uneven.
Summary of the invention
