In view of the influences of such factors as the distribution of furnace gas temperature, blackness and furnace wall temperature etc, to develop theoretically a mathematical model completely including above factors to describe the heat-transfer from furnace gas into heated objects by radiation in a kind of heating equipments is too complicated even impossible. On the other hand , simulation technique , by which a lot of complicated problem in engineering can be solved practically though still unsolved theoretically, has already been in common use in many fields of engineering design. Thus, an attempt has been made to formulate heat-transfer in different kinds of fire-heating equipments in steel industry with simulation technique so as to realize the computerized thermal calculation.Summary. A concept "simulation parameter" is put forward taking a dimensionless form in which all the theoretically unsolvable terms are included. Using the values measured in a certain extent, simulation parameters or coefficients would be able to be determined by trial and error. Proceeding from experimental data and based on the theory of heat-transfer by radiation , the total heat exchange factor φCG, for example , is regarded as a simulation parameter for slab reheating furnace. Values of φCG have been assigned to be 0.64 and 0.3 for heavy oil and gas firings respectively. In the mean time, furnace gas temperature is indicated by a thermocouple being inserted in the combustion chamber across the furnace wall (cf. Fig. 1,2 and 3). A heat-transfer model of heated slab is then given aswhere Q is heat-transfer power in kcal/m2 φ/ hr, Tg the representative gas temperature(K) and Ts the surface temperature of slab (K). The value of φCG would be more proper if modifying it by a empirical flame blackness obtained from observing flame brightness, thus making the raised temperature of slabs masured in better accordance with that calculated. The thermal calcuation for simulative design of other kinds of heating equipments and thermal processes have been exemplified as well, e. g. φCG determination in a combustion chamber of steam boiler; thermal analysis of a ladel or tundish in continuous casting; thermal calculations of coke oven and rotary kiln; simulation parameter of radiation-heated corrugated sheet pack; heat-transfer simulation of acetylene heating for preseured welding of reinforced barsjheat-transfer simulation of solidification during steel casting taking account of heat convection and solidifying deposition; and methods of determining heat -transfer coefficient by use of simulation technique and their application etc.Fig.1 Schematic of 5-zone pusher-type slab reheating furnaceFig. 2 Simplification of heat-transfer calculation of radiation in a furnace Fig. 3 Relationship between blackness εf and toal heat-exchange factor φCG in slab rehating furnaceFig.4 Change of φCG along the height of a boiler s combustion chamber Fig.5 Schematic of a combustion chamber with cross-sectional spiralwaterpipesFig.6 A ladle preheated by gas burner Fig.7 A CC tundish preheated by gas burnerFig.8 Schematic of coke oven and heat-transfer calculation network Fig.9 Specific heat-temperature curve Fig.10 Thermal conductivity-temperature curve(coal and coke-determinedby heat-transfer simulation)Fig.11 Pellet heating in rotary kiln and its characterisic numbers φCG and εg for heat-transfer simulation ( Tg and Ts are measured by short stopping)Fig.12 Sizes of rotary kiln and pellet for heat-transfer mathematical model Fig.13 Radiation-heating of corrugated sheet packFig.14 Absorbing and reflecting of radiations in corrugated sheet pack Fig.15 Simplified heat-transfer model of corrugated sheet pack Fig.16 Heating of pressured welding of RC bars Fig.17 Heat-transfer model of acetylene heated RC bars Fig.18 Heat-transfer simulation parameter-apparent distribution of latentheat in solidification during steel casting Fig.19 Heat-transfer simulation for shaft water-coolingFig.20 Heat-transfer simulation for melting loss - at, blast furnace tuyere due to hot-ir
