The process test can be conducted on conventional coal blending tamping coal blending coking experiments, the appropriate coal blending conditions can be explored according to the cold strength thermal strength indicators of the coke produced, the economy possibility of production can be inferred. To guide production provide information for the rational use of coal resources.

    4. The furnace adopts silicon carbide furnace, which has good resistance to rapid cold rapid heat, small expansion coefficient, no peeling cracks in cold hot conditions, long service life. Specific indicators of furnace brick: refractoriness≥1770℃, 0.2Mpa load softening starting temperature≥1620℃, bulk density 2.50-2.80g/cm3, apparent porosity≤21%, reburning line change (1350℃*2h)≤+0.2 %, normal temperature compressive strength≥85Mpa, thermal shock stability (1100℃ water cooling)≥50 times, flexural strength (1100℃*2h)≥20 Mpa, SiC≥86%, Fe2O3≤1.2%.

    5. The coking process is electric heating on both sides, coal loading coking on both sides of the furnace door, with high degree of automation easy operation.

    6. The computer controls the temperature of both sides of the furnace wall, the error of the two sides of the furnace wall at constant temperature is less than 5℃, records the temperature of the coke cake center the furnace top space, with data storage printing functions.

    7. The computer operating system is Win10, the computer starts the control system modifies the system parameters, dynamically displays the system operating status temperature curve.

    8. The temperature control adopts the artificial intelligence adaptive adjustment algorithm, the heating constant temperature control have no overshoot undershoot.

    9. The user can set the heating curve arbitrarily, the program arrangement adopts the method of temperature time arrangement, which is convenient flexible.

    10. With sensor (electric couple) broken wire, reverse connection indication over-temperature alarm function.
