Effect of the test apparatus and method - dry mass of the surface material of the cooling conditions

The present invention discloses an apparatus and a method for testing influence of cooling conditions on the sub-surface of the dry mass of material, comprising a test piece, the test piece for fixing and simulated cutting heat resistance furnace, and a gas cooling means cooling a liquid medium means, gas The cooling device in turn comprises an air compressor, an air filter, a temperature controller, gas flow meter, barometer, thermometer and air drying tube, air drying duct connected to a first end of the nozzle; a liquid medium comprising in sequence a liquid medium cooling means, liquid flow gauge and a liquid medium pipeline, the liquid medium after the end of the branch line are connected to the first and second nozzles. The present invention does not require the actual workpiece machining, cutting with heat resistance furnace simulation, test operation simple, easy to operate; the initial processing can be tested before the best cooling conditions and parameters of the material, then these fixed conditions and parameters then the actual process, reduce production costs, improve economic efficiency of enterprises.
