direct cost of using castable for burners:
material cost: the unit price of the casting material (NH-70) is as follows: 8500 yuan/t, about 1.52 tons of castable used for replacing 3m, so the material cost is required to be 8500 yuan/t 1.52 tons to 1.292 ten thousand yuan for replacing the castable of the combustor 3 m.
Labor cost: according to the calculation of labor cost in 2019 of our company, the cost of each ton of castable is 1500 yuan/t, and the construction labor cost of the combustor castable is 1500 yuan/t 1.52t 0.228 ten thousand yuan.
The cost of the castable used by the burner is 1.292+0.228 is 1.52 ten thousand yuan.
In summary, the following steps: the combustor uses the prefabricated part within 18 months, the prefabricated part needs to be replaced once, and the directly generated cost is 2.736 ten thousand yuan; the casting material needs to be replaced twice, the cost is 1.52 x 2 to 3.04 ten thousand yuan, and compared with the two, the casting material can be saved by 0.3 ten thousand yuan in one period by using the prefabricated member.
2) Indirectly generated economic effects:
if the 18 months is a service cycle, the kiln shutdown is carried out once due to the burner problem in the cycle, the kiln shutdown time is about 3 days, the loss clinker is 5500t/d 3d as 16500t, the clinker unit price is 350 yuan/t, the cost is 140 yuan/t, and the loss clinker sales profit is 16500 yuan/t (350-.
