Clean heat of SKF bearing
The formation of heat production of wastewater, waste gas, waste salt, dust, noise and electromagnetic radiation etc pollute the environment. Solution heat treatment of FAG bearing environmental pollution, the implementation of clean heat treatment (or green heat treatment) is developed in the direction of heat treatment technology. In order to reduce SO2, CO, CO2, emissions of dust and cinders, has basically put an end to INA bearing the use of coal as fuel, heavy use of less and less, instead of mostly light oil, natural gas is still the best fuel.
Burning furnace waste heat utilization has reached a high degree of optimization of the structure and burner air - fuel ratio of strict control to ensure a reasonable burning under the premise that NOX and CO reduced to a minimum; use of gas carburizing, carbonitriding salt bath and vacuum heat treatment technology alternative waste treatment to reduce the salt and CN-containing toxic contamination of water sources; use of synthetic water-soluble quenching oil to replace part of quenching oil, the use of biodegradable vegetable oil instead of mineral oil to reduce some of the oil pollution.
