Ansteel actively developed and promoted the application of a new process for the installation of calming steel ingot liquid core and achieved significant economic benefits. The process is calculated and analyzed through the mathematical model of large-scale ingot off-line thermal state. The temperature field and solidification field of the ingot are simulated by using the technical parameters of the ingot passing-through. The new ingot condensation mechanism is proposed and verified. Technology to develop a new soaking process system to achieve the calming liquid steel ingot furnace is soaked in heat, after a large number of test data calibration, the process reduces the soaking furnace energy consumption 25 ~ 63%, increasing the soaking furnace production capacity of 12 to 60%, reducing Steel ingot burning 0.3%, improve the ingot pass rate of 0.2%, tons of steel down
