A converter heat treatment parts cooling device

Abstract

The invention relates to a converter heat-treated part cooling device comprising a converter, a cooling oil tank, a smoke exhausting pipeline and a circulating oil way. The cooling oil tank comprises an oil tank, two supports, a lifting basket and a guide pipe; the supports are fixed to the same positions of the opposite inner walls of the oil tank respectively, four side walls and bottom of the lifting basket are in meshed sheet structures, one side wall of the lifting basket is provided with a through hole, and the lifting basket is placed on the supports; the guide pipes include a feed pipe and an oil pipe which are fixed mutually, one end of the oil pipe is provided with a positioning sleeve, the included angle between one end of the oil pipe provided with the positioning sleeve and the feed pipe ranges from 100 to 110 degrees, and the upper end of the feed pipe penetrates a fixed cover plate to connect to the part discharge port of the converter; the smoke exhausting pipeline is connected to the side wall of the oil tank in an inserted manner; the circulating oil way comprises two groups of oil pipelines and oil pumps. By the aid of the device, the rigidity difference of parts is reduced after quenching, and the part quenching quality is improved.

Description

technical field [0001] The invention relates to a cooling device for heat treatment parts, in particular to a cooling device for heat treatment parts of a converter. Background technique [0002] At present, in the heat treatment process of the chain, the oil-cooled quenching process after converter carburizing (or carbonitriding) is more commonly used for parts such as small-sized pin shafts that use low-carbon alloy steel. Conventional converters generally use an open oil tank, and the parts after heat preservation are directly poured into the quenching oil in the oil tank, and the oil tank is circulated or stirred at the same time. During this process, three problems are prone to occur: one is that a large amount of oil fume is produced during quenching, which permeates the workplace and endangers the health of workers; The discharged oil falls on the ground, causing a certain waste of quenching oil. At the same time, if it is not cleaned properly, the quenching oil wil...
