The reasonable selection of the furnace bottom strength of the regenerative heating furnace is closely related to the furnace length, actual heating capacity, heating quality, and furnace operating conditions (combustion load, furnace pressure, maintenance cycle, furnace body life, etc.). However, there is no detailed information on the calculation of the bottom strength of the regenerative heating furnace. Through the selection and calculation of the furnace bottom strength in the medium-plate regenerative heating furnace project of a steel plant, it is ensured that the use effect is basically consistent with the actual capacity of the furnace.SU1 UNIVERSAL MILLING MACHINE (1) The selection of the furnace bottom strength of the regenerative slab continuous heating furnace. When the billet is a room temperature billet and the thickness of the raw material is 150-300mm, it should be based on the heat penetration time of the billet. The furnace bottom strength is generally 600-700kg ( m2.h) is more suitable.LIGHT TYPE DRILL PRESS (2) When continuous hot charging, the heat storage continuous heating furnace can calculate the heating capacity according to experience. Taking the normal temperature billet as the benchmark, the heating capacity will increase by 11% to 12% for every increase in the billet. Calculating its thermal charging capacity, the furnace bottom strength is more suitable at 1050-1150kg(m2.h).Vacuum heat treatment of slender hollow parts (3) Because the average radiation temperature and pressure of the regenerative continuous heating furnace is much higher than that of the traditional continuous heating furnace, under the same conditions, the thermal charging heating capacity can be increased by 45% to 55% compared with the traditional furnace.Vacuum quenching of KMN steel structure
