China Cheap price 6bt Connecting Rod Size - Chain grating machine Grate Plate – Special Metal Detail:
Product Introduction
The grate castings cycle through the grate furnace on a continuous cycle and carry the magnetite iron ore pellets through the process and into the kiln.
Processing Steps:
· In the first section of the grate furnace (drying) the temperatures are fairly low (around 200C to 240C),
· In the second section of the furnace (dehydration) the temperature are higher (around 480C to 520C),
· In the third section of the furnace (pre-heat 1) the process temperature rises (980C to 1020C),
· n the final section of the furnace (pre-heat 2) the process temperature reaches its maximum (1050C to 1100C)
· After the preheat 2 section the grate castings discharge their pellets into the kiln and then run along the return side of the grate in ambient air where they cool down before getting loaded with pellets again and entering the furnace for the next cycle.
The temperatures above are the process gas temperatures that the castings are exposed to. The castings themselves would not quite reach these temperatures and would be slightly cooler.
The thermal cycling of the grate castings is continuous as it cycles through the grate during production.
The maximum temperature of the casting goes to approximately 650C when it discharges its load into the kiln and then the castings cool down to approximately 150C in free air, as it returns to the tail end.
Shanghai Special Metal Co., Ltd supplies very high wear grates for mining environments to maximize its life.
