Hot continuous casting technology

Continuous casting method, also known as heat-type continuous casting method. Absolutely prevent melt-type wall nucleation, the mold is heated to a temperature above the solidification of the melt. Solidification of the melt from the mold only at the moment will be. With the continuous slab leaving the crystallizer, along the direction of the solidification of the melt in the heat flow in the opposite direction but it is heated to a temperature above the metal to be cast above the liquidus temperature, performed. This method is the biggest feature is not mold forced cooling. And by type of slab outside the direct water cooling, the heat along the pull direction of the casting mold from the inlet end of the mold by the surface tension of the liquid metal to maintain the shape and gradually pull solidified the connection process. Significantly reduced ingot and wall friction type, transmission entrance to the cooling zone. Remains liquid metal and mold exposure. Easy to obtain surface brightness feeding works well, complicated cross-sectional shape of the slab; unidirectional solidification along the casting direction. Ease of gas during solidification and inclusion exclusion, so as to obtain pure dense cast material. OCC computer simulation technology temperature field and flow is still fragmented, research field and the solid-liquid interface shape and position of the crystallization process and crystal growth of crystals and other aspects of competition. Unsystematic and also focused on the low-melting metals and alloys.
