Problems solved by technology
Because it directly affects the melting and use characteristics of mold slag, it will cause quality problems such as subcutaneous pores of the billet, and in severe cases, it will cause hydrogen increase in the steel, resulting in steel breakout
[0004] It can be seen that mold slag plays a very important role in continuous casting production. With the continuous progress and development of science and technology, an automatic mold slag feeder for continuous casting molds has been produced, which mainly includes storage hoppers, feeding pipes, coil springs and motors. etc., but the storage hopper in this feeder only serves as a material storage function, and cannot control the moisture and viscosity of the mold powder inside
Moreover, if the mold slag in the storage slag is agglomerated, it will not only be difficult to discharge the material but also have an adverse effect on casting

The invention belongs to the field of additive supplying, in particular to a storage device of an automatic feeder for casting powder. The storage device comprises a storage barrel, a driving device and a stirring device, wherein a discharge opening is formed in the bottom of the storage barrel; the stirring device comprises a motor and a stirring arm, the motor is positioned in the middle of the bottom of a discharge barrel, and the stirring arm is of a frame shape and connected with the motor; the drying device comprises a light wave tube and high-temperature far-infrared insulating paint, the high-temperature far-infrared insulating paint is painted on the inner wall of the storage barrel, and the light wave tube is arranged on the outer wall of the storage barrel. The storage device can dry and stir the casting powder so as to avoid the casting powder to have negative effects on the casting production due to moisture and clotting.
Description
technical field [0001] The invention relates to the field of supplying additives, in particular to a storage device for an automatic mold slag feeder. Background technique [0002] In continuous casting production, except for pouring slabs with small cross-sections, mold flux is mostly used. Mold powder is placed on the surface of molten steel in the mold during continuous steel casting to keep warm, prevent oxidation and absorb non-metallic inclusions. The basic functions of the mold powder are: to protect the molten steel on the meniscus of the crystallizer from the secondary oxidation of the air; it has good auxiliary performance and heat insulation performance, preventing the surface of the molten steel from solidifying or crusting; it can absorb well Non-metallic inclusions that float up to the meniscus; control the speed of heat transfer from the slab to the mold to reduce thermal stress; have a good function of lubricating the slab so that it can be pulled out of the...
