Characteristics of the present invention and effect are:
1, drying, hydrofuge, the separation of sintering function are carried out in different burner hearths zone;
2, the radiation heating section is carried out drying, hydrofuge, and spacious flame bringing-up section is carried out sintering;
3, significantly improve flatness and the cleannes of coating surface, improve product hierarchy;
4, because of the moisture in the coating in the evaporation of radiant-heat drying-hydrofuge section and discharge out of the furnace, spacious flame heat-agglomerating section heating energy consumption significantly reduces.
When 5, entering sintering stage because of the band steel, face coat is solid state, and the solid particle that imperfect combustion produces can not bond to belt steel surface.
Use oriented silicon steel band insulating coating drying device to oriented silicon steel band coating insulating coating and carry out uniformity and the adhesion property that drying can improve the strip steel surface coating thickness, improve the surface quality of orientation silicon steel.
The drying and sintering stove is divided into radiant-heat drying-hydrofuge section 10 and 11 two functional areas of spacious flame heat-agglomerating section, band steel 1, reaches upper and lower surface and is coated with insulating layer coating, drying, hydrofuge, sintering purpose by these two stove sections through coating apparatus 7 surface coating insulating coating reverse hangs;
Arrange in radiant-heat drying-hydrofuge section and be with radiant tube burner 2, naked light burner 4 is set in the spacious flame heat-agglomerating section reaches in the slow drying of difference in functionality zone realization indirect, concentrate hydrofuge and Fast Sintering purpose;
In radiant-heat drying-hydrofuge section, arrange and concentrate humidity-discharging device 5, be mainly used in this section, concentrating and discharge dried water vapour in the coating solution.Prevent that it from entering sintering stage and increasing this section humidity and thermal energy consumption;
Between radiant-heat drying-hydrofuge section and spacious flame heat-agglomerating section, intersegmental partition wall 3 is set, effectively prevent from entering spacious flame heat-agglomerating section at the steam that radiant-heat drying-the hydrofuge section evaporates in a large number, and the flue gas of spacious flame heat-agglomerating section generation affects drying, hydrofuge, the cleaning effect of dry hydrofuge section.
