摘要： Disclosed are a high-pressure liquid-state or supercritical-state quenching apparatus, comprising a working chamber, a heating device, a cooling device, a vacuum pump set, a storage tank, a buffer tank, a gas booster, a first pressure gauge, and a temperature controller. According to the Invention, vacuum liquid-state or supercritical-state quenching is implemented, which satisfies a quenching requirement of a large workpiece, and can also achieve an effect of high-pressure gas quenching. In addition, clean heat treatment is implemented, which avoids waste gas and waste water pollution, and is energy-saving and environmentally-friendly heat treatment.

摘要： An on-line intelligent control method for the cooling characteristics of a quenching liquid in heat treatment production includes the steps of: step 1: subjecting a workpiece to thermal insulation; step 2: measuring the cooling characteristics and the heat transfer coefficient of a quenching liquid followed by correction; step 3: starting cooling; step 4: then changing the internal circulation rate; and step 5: removing the workpiece. This scheme can effectively avoid the problem that the cooling of a workpiece in industrial production deviates from the ideal cooling characteristics of a quenching liquid obtained in a laboratory.

摘要： Disclosed is a supercritical-state cleaning system, comprising a cleaning chamber (4), a gas booster apparatus (11), a first heating apparatus (5), and a carbon dioxide supply apparatus. The cleaning chamber (4) is separately connected to the first heating apparatus (5) and the carbon dioxide supply apparatus. A vacuum pump set (1) is connected to the cleaning chamber (4). Compared with the prior art, in the Invention, air introduced when a workpiece enters a cleaning chamber is completely removed, so as to prevent mixing of CO2 and air, thereby improving a cleaning effect.

摘要： The Invention relates to an atmospheric-pressure acetylene carburizing furnace, comprises a reaction chamber, an acetylene intake duct, an exhaust gas duct, a control and metering apparatus, an exhaust gas measurement apparatus, and a computer controller. The computer controller calculates a total amount of carbon in the furnace and an enrichment rate of a workpiece, and adjusts an acetylene intake volume according to the calculation result until process requirements are met. The Invention realizes carburizing with acetylene under atmospheric pressure and reduces the usage costs while improving the equipment efficiency.
