Development of heat
(1) Clean the heat
Waste water, waste gas, waste salt, dust, noise and electromagnetic radiation, heat treatment etc. formed on the environment pollution. Solve the heat problem of environmental pollution, the implementation of clean heat (or green heat) is one of the direction of the development of heat treatment technology developed. In order to reduce SO2, CO, CO2, and cinder dust emissions, has basically put an end to the use of coal as a fuel, the amount of heavy oil less and less in favor of the majority of light oil, natural gas is still the best fuel.
Furnace waste heat utilization has reached a high degree of optimization and air burner structure - strictly controlled to ensure that the fuel ratio combustion reasonable premise that NOX and CO reduced to a minimum; the use of gas carburizing, carbonitriding and vacuum heat treatment technology to replace the salt bath treatment to reduce waste and toxic pollution of CN- containing water; water-soluble synthetic oil instead of part of the quenching quenching oil, the use of biodegradable vegetable oil instead of part of the mineral oil to reduce oil pollution.
(2) Precision slim ball bearing Heat Treatment
Precise heat treatment has two meanings: one is based on the requirements of parts, materials, structure size, the use of physical metallurgy knowledge and advanced computer simulation and testing technology, optimize the process parameters to achieve the required performance or maximizing material potential; on the other hand is fully guarantee the stability of the process optimization, and product quality dispersity small (or zero) and heat distortion zero.
(3) energy-saving heat
Scientific production and energy management is the most efficient use of energy has the potential factors that a professional heat treatment plant in order to ensure full capacity, full equipment capacity is scientific management options. In terms of heat energy structure, preference primary energy; full use of waste heat, waste heat; using low energy consumption, long cycle process instead of a short period, a large energy-consuming processes.
(4) less non-oxidation self aligning ball bearings heat treatment
By the use of protective atmosphere heating alternative oxidizing atmosphere heated to a precise control of the carbon potential, the potential of the controlled atmosphere of nitrogen is heated, after the heat treatment improved the performance of parts, such as heat treatment greatly reduced decarburization defects, cracks, etc., finishing allowance reduced after heat treatment improve the utilization efficiency of the material and machining. Vacuum heating gas quenching, vacuum or low pressure carburizing, nitriding, nitrocarburizing and boron penetration can significantly improve quality, reduce distortion and improve life.
