西安矿热炉

We are in the process of metallurgical production, the work efficiency is very important to promote work efficiency directly affects the economic benefits, and we are in the time of metallurgical production, when casting speed increased, the molten steel flows into the mold after the shell needs stable and thick enough to ensure the formation of mold out, to prevent leakage of steel therefore, take measures, following on from the small I to give you something to explain simple! 

西安矿热炉

The first point is to reduce the oxygen content in molten steel, smelting to improve a hit rate, eliminate after blowing smelting method, at the same time in the process of tapping with deoxidizer, adhere to adequate enough to reduce the probability of blowing argon in the process of casting nozzle tumor of the product.

The second point is the low temperature casting technology. The low superheat casting is very important to improve the casting speed. The method is: in the steel out of tundish, before entering the mold take heat exchange cooling treatment; adding coagulant in the mold (such as iron powder, iron tablets, iron or iron wire).

The third point is the mould technology of high efficient heat transfer, cooling water flow, using small joints, high velocity, the copper mold processing technology and materials within the same jacket, has guaranteed the water seam uniform avoid off square; multi taper parabolic curve, the solidified shell and the mould are maintained in each section good contact, which greatly improve the efficiency of the crystallizer.

The fourth point is the modification and optimization of the support of the foot roll, and the small diameter foot roller is adopted to prevent the bulging of the billet after the mold is out of shape. At the same time, two rows of strong cold nozzles are added to each slab in the foot roll ring region to strengthen the cooling. In addition, since the three cooling section, the slow cooling method is adopted, and the extended cooling section is extended simultaneously.

The fifth point is to reduce downtime, online replacement of mold, accident accident accident, steel sink groove; the same tundish, steel ingot line replacement head; increase the tundish circular buffer, improve the life of the tundish; the same tundish repair after two times use.

The sixth point is to use multi point bending and straightening, high casting speed, in order to ensure the slab with liquid core in bending and straightening, deformation rate and deformation rate of two-phase region generated control does not occur in the crack allowed value, by 3 point bending straightening technology.

The seventh point is to ensure that the quality of two cold water, in the two cold water into the nozzle before the design of unequal precision of the filter, the water back to the reservoir after the first chemical oil treatment, to ensure that two of the cold water quality.
