  • the heating rate referred to in the present invention is an instantaneous heating rate (temperature gradient (dT/dt) of the heating pattern), not an average heating temperature ( ⁇ T/t) obtained by dividing an increased temperature ⁇ T °C by a time t required for temperature rising.
  • the inventors of the present invention have studied the method of producing ferrocoke, made measurement of the thermal and mechanical property of a molded product of mixed iron oxide-containing material and carbon-containing material as raw materials of ferrocoke, performed thermal stress analysis based on this property and found the heating method optimal for control cracking of the molded product of mixed iron oxide-containing material and carbon-containing material based on analysis results of deformation and cracking of the molded product in heat treatment under various conditions thereby completing the present invention.

  • the bituminous material includes coal such as pitch, soft pitch, middle softening point pitch, and hard pitch and petroleum bituminous material such as ASP (asphalt pitch) and PDA (propane deasphalting asphalt).
  • the oil coke includes fluid coke and delayed coke.
  • Figs. 1 and 2 the transition of maximum thermal stress occurring inside the molded product when the material is heated is illustrated in Figs. 1 and 2 .
  • a raw material containing 100 mass% coal as carbon-containing material and a raw material containing 10 mass% iron ore as iron oxide-containing material and 90 mass% coal as carbon-containing material which are formed into molded products of volumes 18 cc, 50 cc and 92 cc.
  • the molded products are heated at 5K (Kelvin)/min (5 °C/min) of constant temperature gradient.
  • the transition of maximum thermal stress caused inside the molded product containing 100 mass% coal is illustrated in Fig.
  • Fig. 2 the transition of maximum thermal stress caused inside the molded product containing mixture of 10 mass% iron ore and 90 mass% coal is illustrated in Fig. 2 .
  • the thermal stress first, the density, thermal conductivity, specific heat, Young's modulus and temperature-dependent contraction coefficient of the coal and iron oxide-containing coal are measured and this measurement data is used as a basis to calculate the temperature dependency of the thermal stress by heat transfer and thermal stress calculation.
  • the contraction coefficient is measured by a thermomechanical analyzer, using a test sample of a cylindrically molded product of diameter 5 mm and height 8 mm obtained by mixing predetermined amounts of coal and iron ore.
  • the Young's modulus is measured by the resonance method, using a test sample obtained by mixing predetermined amounts of coal and iron oxide and cutting the mixture into a platy of width 15 mm, length 80 mm and thickness 10 mm.
  • the Poisson's ratio is measured based on the method disclosed in the publication ( J.Fukai, T.Hashida, K.Suzuki, T.Miura and S.Ohtani: Tetsu-to-Hagané, vol.74 (1988), p.2209 ) and the specific heat, thermal conductivity and density are measured based on the methods disclosed in the publication ( K.Matsubara, O.Tajima, N.Suzuki, Y.Okada, Y.Nakayama and T.Kato: Tetsu-to-Hagané, vol.68 (1982), p.2148 ).
  • Fig. 5 is a graph illustrating temperature dependency of contraction coefficient of a molded product composed of 100 mass% coal, a molded product composed of 90 mass% coal and 10 mass% iron ore and a molded product composed of 70 mass% coal and 30 mass% ore.
  • the peak that is, secondary peak of the contraction coefficient
  • the contractile rate of the surface becomes maximum when the surface temperature is around 750 °C, while as the temperature inside the material is lower than that of the surface, the contractile rate is relatively low as compared with that of the surface and there is higher possibility that cracking occurs due to contraction difference between the surface and inside of the molded product.
  • the secondary peak is shown of the mixed molded product of coal and iron ore.
  • the peak that is, primary peak of the contraction coefficient
  • the Young's modulus of the coke as molded product composed of 100 mass% coal is small in this primary peak temperature range, as illustrated in Fig. 1 , the occurring thermal stress is relatively small and becomes insignificant.
  • the contraction coefficient in Fig. 5 is shown.
  • the thermal conductivity of the iron oxide-containing material is 100 times greater than that of the carbon-containing material, the temperature difference between the surface and inside of the molded product becomes smaller than that of the carbon-containing material only. The same tendency is shown even when the volume of the iron oxide-containing material is increased. Therefore, as illustrated in Fig. 2 , the peak of the thermal stress of the mixed molded product of the carbon-containing material and iron oxide-containing material becomes smaller to a degree that it can be ignored around the temperatures of 700 °C to 750 °C.
  • the high peak of thermal stress is shown at the surface temperatures of the molded product ranging from 550 °C to 650 °C where the contraction coefficient ranges from its primary peak value to its minimum value.
  • the Young's modulus is small in this temperature range and therefore, the thermal stress becomes insignificant.
  • the molded product composed of a mixture of carbon-containing material and iron oxide-containing material, as the Young's modulus is larger due to influence of the iron oxide-containing material, larger thermal stress occurs even with slight change in strain in this temperature range.
  • the mixture of the carbon-containing material and iron oxide-containing material shows the temperature of the thermal stress which is different from that of the only carbon-containing material. Therefore, as a new finding, in order to prevent occurrence of thermal stress and crack in carbonization, there is only need to control the heating method at the temperatures of 550 °C to 650 °C irrespective of the volume of the molded product, thereby completing the following invention.
  • the following heating method at the temperatures of 550 °C to 650 °C used in the present invention is effective in carbonization of a molded product composed of a mixture of the carbon-containing material and iron oxide-containing material obtained by hot briquetting as well as by cold briquetting in which the content of the iron oxide-containing material is increased and a binder is used.
  • the heating rate mentioned in the present invention is not a heating temperature ( ⁇ T/t) obtained by dividing an increased temperature ⁇ T °C by a time t required in temperature increase, but an instantaneous heating rate (temperature gradient of the heating pattern (dT/dt)).
  • Fig. 3 the transition of the maximum thermal stress occurring inside the molded product composed of 100 mass% coal as carbon-containing material is illustrated in Fig. 3 and that of the molded product composed of 10 mass% iron ore as iron oxide-containing material and 90 mass% coal as carbon-containing material is illustrated in Fig. 4.
  • Figs. 3 and 4 are graphs each illustrating the transition of the maximum thermal stress occurring inside the molded product when the 18 cc molded product is heated at the heating rates of 5, 10 and 20 K/min (°C/min) of constant temperature gradient. For each raw material, the smaller the heating rate, the smaller the maximum thermal stress.
  • the upper limit of the heating rate at the temperatures of 550 °C to 650 °C in carbonization of the ferrocoke is 20 °C/min (K/min) and when it is heated at the heating rate of 20 °C/min or less that is instantaneous temperature gradient, there occurs almost no crack in the molded product.
