Heat treatment quality direct relation with the subsequent processing quality so that will ultimately affect the using performance and life of the parts, and at the same time,SKF 22206CCW33 Bearings Clearance http://www.skfbearing-china.com/product/SKF22206CCW33-bearings-64905.html heat treatment and mechanical industry of large energy

consumption and pollution. In recent years, with the progress of science and technology and its application in the field of heat treatment, heat treatment technology development mainly embodied in the following aspects:
(1) clean heat treatment formed by heat treatment production wastewater, waste gas, FeiYan, dust, noise and electromagnetic radiation can cause pollution to the environment. Solve the problem of heat treatment of environmental pollution,

implementation of clean heat treatment (or the green environmental protection heat treatment) is one of the developing direction of the heat treatment technology in the developed countries. For reducing SO2, CO, CO2 emissions, dust and

coal cinder, have put an end to coal as fuel, fewer and fewer in the use of heavy oil, diesel oil in the majority of natural gas is still the most ideal fuel. Combustion furnace waste heat utilization has reached a very high degree,

burner structure optimization and the strict control of air - fuel ratio, to ensure the reasonable under the premise of combustion, NOX and CO to reduce to a minimum; Using gas carburizing, carbonitriding and vacuum heat treatment

technology instead of salt bath treatment to reduce FeiYan and contain CN - a poison to the water pollution; With water soluble synthetic quenching oil instead of part of the quenching oil, using biodegradable vegetable oil instead of

part of the mineral oil to reduce the oil pollution.
(2) precision heat treatment precision heat treatment have two meanings: on the one hand, is based on the use requirements of the parts, material, structure, size and the use of physical metallurgy knowledge and advanced computer

simulation and testing technology, optimization of process parameters, to achieve the required performance or maximize the potential of materials; On the other hand is fully guarantee the stability of the optimization of process,

implement quality dispersion is small (or zero) and heat treatment distortion is zero.
(3) energy saving heat treatment of the science of energy production and energy management is the effective use of the most potential factors, establish a professional heat treatment plant to ensure the full production, give full play to

the equipment capacity is the choice of scientific management. In terms of heat treatment energy structure, energy choice time; Make full use of waste heat, waste heat; With low energy consumption, short cycle of process instead of the

long cycle, energy consumption, etc.
